Chapter 1 Introduction 
The Advanced Reporting Module is an add-on module for the VestasOnline® 
Business extending the features available in the Standard Reporting Module. 
The Advanced Reporting Module consists of a number of sub-modules all 
targeted at different system users. The Advanced Reporting sub-modules 
described in this manual are Shadow Data Editor, Template Designer, 
Calculation Procedures and Profile Administrator. 
Besides the sub-modules this manual also describes the Calculation Procedures 
by means of the collected data, shadow data, reporting system process work 
flow and calculation formulas behind report columns. 
 
Shadow Data Editor - is used for the maintenance of data in the 
database. It is primarily a tool for on-site 
operators responsible for downtime 
allocation and data integrity. 
 
Template Designer - is targeted at the system administrator 
enabling him or her to make custom 
report templates that address site-specific 
requirements. 
 
Profile Administrator - is designed to be used by the person 
responsible for the configuration of the 
system and the creation and maintenance 
of reporting profiles. 
 
Calculation Procedures - describes collected data, shadow data, 
reporting system process work flow and 
the formulas behind some of the report 
columns used by the VestasOnline® 
Business Reporting Module (Standard and 
Advanced). 
 
 
 
 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 2 
Chapter 2 Shadow Data Editor 
The Shadow Data Editor sub-module enables users to edit the data that form the 
basis of the reports created by the Report Generator. 
 
Shadow data are data generated by copying, calculating or modifying the 10-
minute data received from all the units of the wind park. The basic idea of 
reporting using Shadow Data is that the original 10-minute data are kept 
unchanged as when they were received by the VestasOnline® Business Server. 
Neither automatic nor manual data modifications will influencethe original 10-
minute data as all modifications are made on the shadow data only. 
 
Apart from the automatic calculations of shadow data by the report module, it 
further allows for manual editing in the Shadow Data table and the Shadow 
Data Editor is the tool provided for this purpose. 
 
Note: It is very important that people using the Shadow Data Editor agree on the detail 
level used in the Shadow Data Editor so that information will be stored in a consistent 
way. 
2.1 The basic windows for editing of shadow data 
Start editing by clicking the menu item Shadow Data Editor in the Maintenance 
submenu in the VestasOnline® Business Server menu. 
 
 
Figure 1 - The opening window of the Shadow Data Editor 
The opening window in Figure 1 that is part of the Shadow Data Quick Tools is 
used for selecting the profile, the time period, the view and the park unit – see 
section 2.4 The Shadow Data Quick Tools for more details. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 3 
2.1.1 Profile 
Report profiles contain the basic rules for data handling and report generation – 
see chapter 4 – Profile Administrator for more information. 
Start by selecting the profile (the profile selection is the only part of the window 
that is active when the window is opened). To select a profile, click the down 
arrow and choose a profile from the drop-down menu. 
 
When you have selected the profile, the opening window changes as the rest of 
the window becomes active. This is indicated by change of text colour from grey 
to black for the now active features. At the same time, the first unit of the profile 
is selected as default in the unit field. 
2.1.2 Date and time details 
The editing period can be selected by means of the calendar and the duration 
selectors at the right hand side of the window. At the top of the calendar, you 
select the month. By clicking on the left arrow you can go to the previous month 
and by clicking on the right arrow you will go to the next month. If you point to 
one of the arrow keys with the left mouse key and hold it down, the calendar 
will continue to change months. A left-click on the name of the month opens a 
month list in which the month may be selected by left or right clicking on the 
name of the month. A left click on the year opens an up-down selector where 
you can change the year by clicking on the up and down buttons. The date is 
chosen by clicking the date in the month calendar. The present date can be 
selected directly by clicking at the bottom left corner of the calendar. To select 
the editing period, use the selectors below the calendar. The one to the left is the 
number of days, weeks, months or years that is selected in the field to the right. 
2.1.3 Park unit 
The desired unit can be selected in the Park Unit field placed below the Profile 
field. Select a unit from the drop-down list. 
2.1.4 View 
All 10-minute values: 
 
Offers a 10-minute data detail level where it is possible to view all relevant 
details and to make manual changes 
 
Collapsed view: 
Only displays events with processed information for the relevant report 
columns 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 4 
2.1.5 Retrieving data 
When you have selected the profile, the time period and the unit, click the 
Retrieve button. 
 
The data retrieval may take 
some time depending on the 
length of the time period 
selected. As long as the data 
retrieval is active, the 
information box shown to 
the left will be open.

selector in the toolbar. The drop-down list of this field 
comprises all the wind turbine units of the profile selected. 
Select the unit to be edited from the drop-down list and the data for this unit 
will be retrieved. If data from another unit are already in the editor, you will be 
prompted to save these data before they are overwritten. 
2.2.3 Presentation of unit information 
 
The View Information icon in the tool bar presents basic information 
about the selected park unit. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 6 
 
Figure 4 - Unit information window 
The Information window provides information about the unit such as type, 
power, reference curve, event list, neighbouring turbines and associated 
meteorological stations as well as commissioning date and information about 
last service/maintenance visit. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 7 
2.3 Database maintenance tool 
Many of the columns in the shadow data table are editable and values may be 
inserted in the fields of these columns. Section 2.6 describes how values can be 
inserted, but the procedures described in section 2.6 may take a while if a larger 
amount of data is missing. In this case, you can use the following procedure: 
 
 
Figure 5 - Shadow data table 
 
 
 
 
 
The example in Figure 5 contains a shadow data table in which data 
from the time interval from 15:20 to 15:50 are missing. 
 
You can insert average values in such rows by using the tool 
associated to the icons shown to the left. A click on one of these icons 
will open a selection window. 
 
The first icon will open a park maintenance tool for the park unit 
currently selected while the second icon will open the tool for all units. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 8 
 
Figure 6 - Selection window for the shadow data – Park Maintenance tool 
 
The selection window shown in Figure 6 (which can be opened only if a row 
without data has been selected (Figure 5)) displays general information in the 
upper part and contains selection boxes in the lower part. 
 
When you open the window, the Set Production option is selected as default 
and the values derived from the production counters are shown as blue on 
white in the selection boxes. Furthermore, you can select status code, wind 
speed and expected production. 
 
The values shown in blue are the ones suggested by the maintenance tool (you 
can change these values, however). The proposed wind speed is calculated from 
the proposed, average production by going backwards through the reference 
power curve. 
 
In the Description field, you may add a comment. See an example in Figure 6. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 9 
 
Figure 7 - The selection window after selections have been made and a comment has been added. 
Figure 7 shows howselections can be made. All selection fields have check 
marks indicating that all the values at the right hand side will be inserted in the 
database. A comparison between Figure 6 and Figure 7 shows that some of the 
values/settings and a comment have been added. 
 
When you have made your selections, click the Proceed button. 
 
 
Figure 8 – Save manually entered data dialog box 
The Save dialog box will pop up. Click Yes to save the data.

 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 10 
When the data selected in Figure 7 has been inserted, the shadow data table will 
look as shown in Figure 9. 
2.3.1 Mass-editing tool 
The Mass-Editing function is a convenient and time-saving tool as it lets you 
insert or modify shadow data for a number of units in one operation. The 
specified information will overwrite any existing shadow data information. The 
maximum period for a mass-editing operation is 48 hours. 
The icon for the Mass-Editing function is located at the far right in the 
Shadow Editor toolbar. Click the icon to open the Mass-Edit window. 
 
The upper part of the window lets you select the wind turbines on which you 
want to make corrections to the shadow data. 
 
The middle part contains the actual editing tools, while the lower part lets you 
specify the time period for the corrections. 
 
 
Figure 10 – Mass-Editing Tool window 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 11 
Select the checkboxes for the information columns that you want to modify and 
enter the new values. These values will be applied to all selected units for the 
specified time period. 
 
In the above illustration three fields are labelled “Not used”, as these categories 
have not been configured for the selected reporting profile. If configured, they 
will appear as shown below. 
 
Figure 11 – Mass-Editing Tool window – Modify shadow data section

keying the event code directly in the Find all Turbines with Event Code field. 
2.4.3 Filter 
The Filter function acts on the data for the selected wind turbine and is used to 
search for 10-minute periods fulfilling specific criteria among the displayed 10-
minute periods. The Filter function allows you to find the relevant 10-minute 
periods in an easy way even when data for a longer period are being analysed. 
 
 
Figure 15 - The Filter tab of the Shadow Data Quick Tools 
As shown in Figure 15, a number of filtering options are available. Except for 
the No Filter option, it is possible to display only those 10-minute periods that 
fulfil a specific criterion regarding either Status Code, Category, Wind Speed, 
Production or Expected Production. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 14 
The Status Code and Category options both have a field for defining search 
criteria. Click the down-arrows to have the possibilities listed. The Missing 
possibility is always an option and the other possibilities will be the Status 
Codes or Categories that are part of the data selected for display. 
 
Figure 16 - Example of possibilities - Category 
The section of the window shown above illustrates how a category is selected. 
In this example, three different categories are present in the selected 10-minute 
periods. 
 
The three options - Wind Speed, Production and Expected Production - are to be 
selected in the same way. The user may ask for all 10-minute periods in which a 
value is missing, for all 10-minute periods containing a value below a user-
defined limit or for all 10-minute periods holding a value above a user-defined 
limit. 
 
 
Figure 17 – Example of selections – Wind speed, Production, Expected production 
The selections Missing, Above and Below are made by using the down-arrow

Figure 20 – Example of shadow data from a meteorology station 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 17 
2.5.1 Colour coding of shadow data (Legend tab) 
The shadow data concept implies that the data in the shadow data table can 
have different origins. Some data come from the original 10-minute data 
packages from the units; some are based upon data from other units and some 
have been manually entered etc. Therefore, colour coding is applied to make it 
easier for the user to see how the data have been created. 
 
 
Details about the colour coding are available in the Shadow Data Quick 
Tools. Click the icon in the toolbar of the Shadow Data Editor window 
(Figure 3) and further click the Legend tab.

Note that shadow data are affected by the selection of AOM service contract 
(AOM 4000 or 5000) for each turbine in the wind power plant. Thus, for turbines 
with an AOM 5000 service contract, an additional shadow data column value is 
available – Average actual production (located in line 42 of the Shadow Data 
Details window for turbines with an AOM 5000 contract – see Figure 23). 
Average actual production calculates average production from all turbines of the 
same type, except production from the actual turbine itself, primary and 
secondary neighbour turbines, and de-rated turbines. As seen in Figure 23, the 
additional column affects the prioritisation for calculating lost production for 
turbines with an AOM 5000 contract. 
Configuration of shadow data according to service contract is defined in Profile 
Administrator, Profile properties (see 4.3 Creating profiles). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Figure 23 - Shadow Data Details – turbines with AOM 5000 service contract 
The information columns preceded by a check mark are displayed in the default 
setup of the shadow data table shown in Figure 19. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 20 
To include/exclude a column, click the corresponding check box. 
 
In the Shadow Data Details table, the columns with the check marks, the line 
number column and the Property column are common for the whole data table 
whereas the Value column contains the actual value for the selected row in the 
shadow data table. 
 
The rows in blue text in the shadow data details table have all been edited 
manually. 
 
Line 5 – “Edited by” text deviates from this general rule. The user name of the 
user editing in a row of the shadow data table is automatically inserted when 
the changes are transferred to the database. 
Smart columns 
Some of the lines in the Shadow Data Details table appear in grey. This indicates 
a “Smart Column”, i.e. a column where the value is determined by selection 
among a number of options with a certain order of priority. For example, 
Expected power (line 42, AOM 4000 / line 43, AOM 5000) will display the value 
from line 37 (Expected Production – manually edited) if this information is 
available. Otherwise, it will display the value from line 38 (Neighbour 
production) if this information is OK and so on down to the last option which is 
the value of line 39 (AOM 4000) / line 42 (AOM 5000). 
2.6.1 Editable columns in the Shadow Data table

selection for historical presentation. 
 
 
Figure 44 – View of a Historical Report 
The print options for Historical reports are identical to those of the General 
reports (see section 3.6 Standard Reports). 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 40 
3.8 Event Reports 
In contrast to the Standard and the Historical reports that are based on 
customized report templates, the Event reports are based on a single pre-
defined report template that cannot be modified. 
Instead, selections for targeting reports are made directly from the Report 
Generator every time an Event report is generated (see Figure 45). Note that 
Event reports can be filtered to include a single wind turbine event or all events 
for the selected reporting period

Chapter 4 The Profile Administrator 
The Profile Administrator module manages creation and maintenance of report 
profiles. 
 
A report profile is a set of basic setup rules for data handling and report 
generation. The profile defines the Reference curves, the park units and the 
parameters to be used and states the categories to be used for categorization of 
the events. It is possible to define many profiles for the same wind park, 
allowing creation of reports in different ways all depending on the purpose of 
the reports. 
 
An owner could, for example, have some profilesreflecting his needs, the 
manufacturer other profiles focusing on e.g. availability and maintenance and 
the utility could have profiles delivering information about the influence of the 
wind park on the grid and vice versa. However, Vestas recommends that you 
limit the number of reporting profile per wind power plant due to the 
maintenance of report profiles. 
 
A profile once created cannot be deleted. If a profile might need to be deleted, a 
JIRA SCADA Support task has to be created. Subsequently, the SCADA Support 
team will delete the informed profile. 
 
 
Figure 48 - The basic window of the administrator sub-module 
The window shown in Figure 48 appears when you select the Profile 
Administrator item in the Administration submenu in the VestasOnline® 
Business Server menu. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 43 
In all VestasOnline® Business modules, a number of tools are available. The 
toolbar icons shown in most windows of the Profile Administrator are described 
below: 
 
 
Closes the application window. 
 
Opens a report menu where different print output options can be 
selected. 
 
Refreshes the data (reloads the data from the database). 
 
Copies table data to the clipboard. For example to export the data to a 
spread sheet. 
 
4.1 Overall configuration 
The area just below the toolbar contains information about the overall 
configuration of the park and not only for a specific profile. The icons have the 
following functions: 
 
 
Opens the Reference Curve Editor window (see section 4.9). A power 
and a wind distribution reference curve should be made for each wind 
turbine type and can be attached to a wind turbine in the park unit 
configuration. 
 
 
Opens the profile and template access setup facility (see section 4.12). 
In this window, access to profile and templates can be setup for all 
users. 
 
 
Opens the Validation Parameters window (see section 4.13). 
 
 
Opens the Free Wind Parameter Setup window (see section 4.13). A 
correlation of parameters can be attached to a wind turbine in the park 
unit configuration. 
 
 Opens the Wind Exclusion Sectors window. A wind sector group can 
be defined with a number of wind sectors. A wind sector group can be 
attached to a wind turbine in the park unit configuration (see section 
4.14). 
 
Reference curves, validation parameters and free wind parameters should be 
defined before a report profile is defined. In case you change these after you 
have defined a profile, the shadow data will need to be regenerated. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 44 
4.2 Report profile configuration 
The Report Profile Configuration area of the Profile Administrator window 
(Figure 48) contains information about the profiles available for the user logged 
in. The list of profiles only shows the profiles to which the user has access 
according to his or her password. 
 
The first column is the title of the profile. 
 
The second column indicates if the profile is locked. If a profile is locked, 
nobody can change the configuration of the profile. All users with access to a 
profile may lock it. A locked profile can only be opened by the system 
administrator. 
 
The Start Date column indicates when data are available for the selected profile. 
You select the start date when you create the profile. The start date cannot be 
changed. 
 
A continuous generation of shadow data can be enabled or disabled. The status 
for this job is shown in the Auto Generate Shadow Data column and can be 
changed in Profile Properties. 
 
A change in the profile configuration will require that all shadow data have to 
be regenerated. The Shadow Data Status column indicates whether regeneration 
is needed or not. 
 
Below the list of profiles, a description of the selected profile is found. This text 
can be edited by clicking the Profile Properties button. 
 
A number of buttons have different functions that concern the profile 
configuration. Select a profile from the profile list before activating one of the 
functions. 
4.3 Creating profiles 
Note: Before creating a new report profile, make sure that this report profile has not been 
created already by one of your colleagues who has forgotten to grant you access to the 
report profile. 
 
The creation of a profile comprises a number of steps. 
 
Click the Create New Profile item. 
 
The Profile Properties window shown in Figure 49 appears. 
Enter the title of the profile in the Title field and make a description in the 
Description field. In the Contract field, select the service contract that should be 
applied to the report profile (AOM 4000 or AOM 5000 contract). The selection 
made is decisive for the calculation and presentation of shadow data in the 
Shadow Data Editor (see 2.6 Editing and presenting shadow data). 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 45 
 
 
Figure 49 - Window for profile name, description and contract selection 
Do not select the Lock Profile for all Future Changes field, as this will inhibit 
further editing. This field should only be signed off when you have finished 
editing the profile and only if you want to prevent subsequent modifications of 
the profile. 
 
The field Auto Generate Shadow Data should be selected if you want shadow 
data to be generated continuously. It is possible to disable/enable the auto-
generation of shadow data by editing in the Profile Properties window after the 
profile has been created. 
 
The third option - Enable integrity calculation on standard reports - includes 
information about the percentage of categorized 10-minute values in all 
standard reports. If the categorization value for a wind turbine is below 100%, 
this will be indicated by the actual categorization percentage in the reports - see 
Figure 36 – Example of a standard report with categorization percentage. To 
secure accurate calculations in reports, all 10-minute values must be 
categorized. 
 
Finally, the fourth option – Add park units to profile – automatically includes 
all units in the new profile. To close the Profile Properties window and save the 
profile, click OK. Click Cancel if you want to stop the creation of a new profile. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 46

list boxes moves the selected (blue) units from the Available list box to the 
Selected list box. The button above the green single-arrow button moves all 
units to the Selected list box. 
 
The red single-arrow button moves the selected (blue) units from the Selected 
list box back to the Available list box. The button below the red single-arrow 
button moves all units in the Selected list box to the Available list box. 
 
The selected units in the right list box will be assigned to the profile when you 
click the OK button. When you assign the first units to a new profile, the start 
date for the new profile must be selected.VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 48 
If any units have been removed from the profile, all shadow data for these units 
will deleted from the database. A warning will be displayed before this 
happens. 
The start date selection 
window will have the current 
date as default and further 
shows the date limits for the 
database. The start date must 
be within the allowed range. 
To select a date different 
from the default date, click 
the down-arrow. A calendar 
will pop up. 
 
At the top of the calendar, you can select the month.

Editing units selected for the profile 
The window indicates that the profile now has a number of wind turbines 
assigned. The default settings for the wind turbines have been transferred to the 
profile but you may edit them as required. 
 
The editing of park units is not possible if the profile is locked - please note that 
if the profile is locked both the Edit and the Add and Remove buttons will be 
dimmed. 
 
Reference curve assignment 
A wind turbine normally has a reference curve assigned per default. To choose 
a different reference curve, double-click the Reference Curve field and select a 
reference curve from the options in the drop-down list. 
 
 
Hint: The button in the toolbar of the basic window of the Profile 
Administrator module gives access to the Reference Curve Editor 
described in section 4.9. 
 
Editing hub height 
The hub height of the wind turbine is of importance when the expected output 
is calculated because the air pressure and temperature and thus also the air 
density depends on the actual height. The hub height is used when processing 
the height difference from the wind turbine to the met mast as the air pressure 
changes with the height. 
 
The hub heights of the different units are entered by selecting the hub height 
fields one by one. To edit the hub height, left-click the hub height field twice 
and enter the hub height as metres above sea level. 
 
Editing assignments of neighbouring wind turbines 
A wind turbine may have a default assignment of primary and secondary 
neighbours indicating the priority of the neighbour wind turbines to be used 
when data from a neighbouring wind turbine are required. In the example in 
Figure 52 assignment of both primary and secondary neighbouring wind 
turbines is made. 
 
To edit an assignment, left-click on the field and select from the options in the 
drop-down list. 
 
Editing meteorology station assignment 
Usually a wind turbine has default assignment of the primary, secondary and 
alternative meteorology station, indicating the priority of meteorology stations 
regarding meteorology station data for calculations on the wind turbine. 
To edit an existing assignment or to create a new assignment, left-click the 
respective met-station field and select an option from the drop-down list. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 50 
Editing site calibration 
To edit a value, left-click on the field twice. The field will go into edit mode and 
a wind speed compensation value can be entered. Typically, this value is used 
to compensate for difference between wind speed measured at the wind turbine 
and at the meteorology station or to compensate for turbulence from 
neighbouring wind turbines. 
 
Editing pitch angle 
To edit a value, left-click on the field twice. The field will go into edit mode and 
a value can be entered. 
 
Editing free wind parameter 
To edit an existing assignment or to create a new assignment, left-click the field 
and select from the options in the drop-down list. 
A new configuration set of the free wind parameters can be made in the Free 
Wind Parameter Editor. 
 
The free wind 3rd order polynomial will be applied to the collected wind speed 
and stored as the free stream wind speed in the shadow data. This is marked as 
green in the Shadow Data editor. 
 
The correlation is processed based on an analysis performed in the wind power 
plant by measuring the wind speed on the reference met mast and the wind 
turbine – giving the wind speed angle and data from a few months, a 3rd order 
polynomial can be extracted. These wind studies are typically performed by a 
third party institute. 
 
 
Editing wind sector group 
To edit a value, left-click on the field twice. The field will go into edit mode and 
a value can be entered – see section 4.14 Wind exclusion sectors for more 
information. 
 
The wind sector group contains a definition of a 3rd order polynomial that can 
be applied to a given sector, defined as a range of degrees from the nacelle 
position. Each sector can also be defined to be excluded for Power curve 
presentations. The corrections are applied on the wind speed measurements 
from the nacelle anemometer using the angle from the nacelle position. 
 
 
Editing connection point 
To edit a value, left-click on the field twice. The field will go into edit mode and 
a value can be entered. 
 
The connection point defines the Grid connection point of the Wind Power 
Plant. This can be applied if there is a Grid measuring station (VestasGridPanel 
(VGMS III) / ION76x0) installed on the Wind Power Plant. 
 
To select the grid station, you will need to add the grid to the report profile. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 51 
Typically, this is used for processing possible power and other data related to 
the grid connection point - often used for wind forecasting purposes. 
Transfer of selected and edited data 
 
Figure 53 - The park units after user editing 
When you have finished editing all unit parameters, the park units may look as 
shown in Figure 53. 
 
To transfer the result of the selections and the subsequent editing to the 
database, click the Apply-button. When the Apply button turns grey, the 
transfer is finished and you can close the window by clicking the OK button. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 52 
4.3.2 Selecting and creating categories 
Events and categories 
Each wind turbine type includes a list of events. The wind turbine controller 
records changes in the operational status of the wind turbine as events. Each 
event has a descriptive text and an event code which is a number used in the 
registration of the events. 
Typical events are: 
 Overvoltage 
 Vibration 
 Overproduction 
 High wind speeds 
 Warnings 
 Service 
and more. 
 
Warnings are always considered 'Normal operation', as the turbine is available 
and can produce power during this state. Only downtime when the turbine has 
an alarm and stopped/paused should be categorized to other categories than 
'Normal operation'. 
 
Occurrences of events indicate that the wind turbine has an abnormal or 
unintended status, normally causing loss of productionand reduction in 
availability. 
 
One group of events is related to grid problems, another is related to the 
environmental conditions, and some events can be grouped as wind turbine 
alarms etc. 
 
Events with certain similarities are grouped in categories such as Owner, Utility, 
Environmental and Manufacturer. 
Selecting and adding categories 
For each profile, a selection of the categories must be made. You may also create 
new categories for a profile. All categories created are available for all the 
profiles in the report module. 
 
To select categories, start by clicking the Category 
Configuration button in the Profile Administrator 
window. 
The Categorize Events window emerges. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 53 
. 
Figure 54 – Window for selection of categories 
The Category Set function in the upper part of the Categorize Events window 
allows you to group frequently used combinations of categories into Category 
sets. 
 
Four Category sets are available: 
 Standard 
 Downtime type 
 System Component 
 Spare 
 
The pre-defined combination of categories for each Category set is modified by 
including or excluding categories from the group. Your modifications are saved 
by clicking OK. 
 
Note: You cannot de-select a category if it is in use, i.e. if one or more events 
have been allocated to the category in question, or if the category has been 
entered manually in the Shadow Data Editor.
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 54 
The Manage button lets you modify the name of a Category set and its position 
in the Category set drop-down list. 
 
 
 
The center part contains a list of the available categories. 
 
The bottom part of the window contains a Description field with a description 
of the category selected (shown highlighted) in the upper part of the window. 
The lower right field displays a list of the profiles using the category selected in 
the upper part of the Categorize Events window. 
 
Categories are selected by clicking the respective check boxes in the upper part 
of the Categorize Events window. The selection is transferred to the database 
when you click the OK button that also will close the window. 
4.3.3 Categorizing events in the event list 
After having selected/created categories, you must assign one of the categories 
to each event, which is to be categorised in the profile. In case an event is not 
categorized, the 10-minute data will not be auto-categorized and this will have 
to be handled manually. 
 
A profile may contain different wind turbine types having different event lists. 
In such cases, the event list to be categorised must be selected before the 
categorization. 
Select event list 
The categorization is initiated by clicking the Categorize 
Events button. If all the wind turbines in the profile have 
the same event list, the window shown in Figure 56 is 
opened. 
 
Figure 55 – Category – Event List selection window 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 55 
In case of profiles having more than one event list, the above selection window 
is opened. The window contains list boxes with all the categories and event lists 
relevant for the profile. 
 
Select the event list to be categorized and click the OK button. The selection 
window then closes and the window in Figure 56 opens. 
 
 
Figure 56 - The Categorize Events window 
Categorize events 
The toolbar in the allocation window shown in Figure 56 contains the following 
icons: 
 
 
The two icons can expand and collapse the list. The expanded 
view shows all events; the collapsed view shows only events that 
are enabled by default for the controller type. 
 
The list with categorised events can be exported to a XML file 
and exported files can be imported into an existing list. 
 
The table contains all the events in the selected event list shown with Event 
Code number and Event Title to the left. The rest of the table contains columns 
with all the categories selected for the profile. 
 
The check marks indicate the actual category event allocations. The 
checkmarks indicate the default category event allocations (system stem 
data). An event can only have one category allocated but does not necessarily 
have one allocated. 
 
Note: The event code: “ 0 – Turbine OK” is always assigned to Normal Operation and 
cannot be assigned to other categories. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 56 
Event Codes that do not apply to the specific wind turbine can be removed in 
the Expanded view by left-clicking the event text. The text will turn red and is 
not displayed in the Collapsed view. 
Unless the profile is locked, you can add or remove a check mark by left-
clicking the check box. By left-clicking an existing check mark you can remove 
the mark and thus the event will have no category assigned. When the 
categorisation matches your wishes, click the OK button. The information will 
then be transferred to the database. 
 
The space key on your keyboard can be used instead of left-clicks with the 
mouse and the four arrow-keys on the keyboard can be used to move around in 
the allocation area. 
 
If the profile has more than one event list associated, the steps in section 4.3.3 
have to be repeated until all event lists have been categorised. 
 
Event 309 – Remote pause over RCS 
Event 309 – Pause over RCS is unique as this event has associated ‘source’ 
information. The ‘source’ information is used to indicate the responsible party 
for pausing a wind turbine. Consequently, event 309 will occupy several lines in 
the list for categorization of events – see figure 54 below. 
 
Event 309 is the only event with associated ‘source’ information.

Remapping categories 
The Remap function offers a fast way of modifying a previous categorization as 
it lets you move all events from one category column to another. 
 
Click the Remap button to open the Map Category window; then select the 
source and destination columns from the two drop-down lists and click Move. 
 
The checkmarks are now moved from one column to the other. 
 
 
Figure 58 - Map category window 
4.3.4 Shadow data generation 
Generation of shadow data is the last step in the creation 
of a new profile. If the start date lies earlier than the 
current date, click the Regenerate Shadow Data button in order to have shadow 
data generated for the period elapsed since the start date selected. 
 
For more details about the generation of shadow data, see section 4.7. 
4.4 Locking a profile 
When you have completed the profile, you can choose to lock the profile. This 
could be relevant if e.g. the profile is used in a contractual context. 
 
Locking the profile is done in Profile Properties window (See Figure 49). You 
will be asked whether the profile is to be locked and informed that future 
changes in case of locking will require unlocking by the system administrator. If 
you confirm that the profiles shall be locked, the check mark changes to grey 
and the information is transferred to the database when you click the OK 
button. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 58 
A profile may be locked as soon as it has been created or any time after. 
 
When a profile is locked, this buttonmay be used to 
unlock the profile (for system administrator only). 
 
4.5 Editing existing profiles 
It is possible to edit an existing profile by using the procedures described in 
section 4.3 if the profile is unlocked and the user has the appropriate access 
rights. 
 
Regeneration of the shadow data may be required after editing (see section 4.7). 
4.6 Removing profiles 
It is possible to remove a profile if the profile is unlocked and the user has the 
appropriate access rights for doing so. Click the Remove button shown in Figure 
48 when you have selected the profile from the list of profiles. 
 
 
Figure 59 – Remove profile dialog box 
The window shown above will pop up informing you about the consequences if 
you remove the profile. To confirm the removal, write YES (in capital letters!) in 
the white text field and click OK. 
 
All reports based upon the profile and the profile's shadow data will 
subsequently be deleted together with the profile. 
 
4.7 Generation/regeneration of shadow data 
The shadow data may need regeneration if the profile has been modified in the 
Profile Administrator in order to have the changes reflected in the existing 
shadow data. This signalled by the “Config changed – regeneration needed” 
message in the Shadow Data Status column in the Profile Administrator 
window. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 59 
 
Figure 60 – Regeneration is required 
In case a new profile has just been created, shadow data will need to be 
generated if the start date of the profile differs from the present date. Shadow 
data will thus be generated for the period lying between the start date and the 
present date. 
 
The generation/regeneration of shadow data is started by clicking the 
Regenerate Shadow Data button in Profile Administrator window. 
 
 
Figure 61 – Regenerate Shadow Data window 
The box shown above pops up when you click the button. A regeneration may 
change all the existing shadow data apart from the manually inserted values 
and you are therefore asked to confirm the regeneration. 
 
After the confirmation is given, the regeneration of data will start. This is 
indicated by the Generate Shadow Data dialog box shown below. 
 
Note: This dialog only indicates the start of the regeneration process – NOT that the 
full Shadow data generation has completed! 
 
 
Figure 62 – Status window for generation of shadow data 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 60 
The actual generation/regeneration can be a time-consuming process, which for 
a large wind park and/or data for a long period may last for more than an hour. 
This information is shown in the Profile Administrator window. 
 
 
Figure 63 - Status of the regeneration process in the Profile Administrator window 
When the generation/regeneration is finished, “OK” will be displayed in the 
Shadow data status field. 
4.8 Shadow Data Sign-off Management 
Shadow data can be locked (‘signed off’) for a selected period of time. The 
purpose of the locking functionality is to prevent further editing of shadow data 
when Vestas and the customer have come to an agreement about the allocation 
of events for a time period. 
 
Locking and unlocking of shadow data can be done at any time both by a 
designated Vestas administrator and by the customer upon agreement between 
the parties. 
 
 
Figure 64 - Periods of locked and unlocked shadow data in the Shadow Data Sign-off Management window 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 61 
Shadow data are locked or unlocked by selecting the time period in the drop 
down menus and setting or removing the ‘Lock shadow data’ check mark. The 
Description field must also be filled in before the action can be performed. To 
confirm the locking or unlocking of a period a password is also required as 
shown in Figure 65. 
 
 
Figure 65 – Locking shadow data for a specific time period 
The dongle is used to recognize whether locking or unlocking of data is being 
done by a customer or by a Vestas administrator. Thus it is not possible for a 
Vestas administrator to lock/unlock shadow data as a customer and vice versa. 
 
As soon as one of the parties has locked a period of shadow data, it is no longer 
editable until the period is unlocked again. 
 
Figure 66 shows how locked periods are indicated in the Shadow Data Editor. 
The locked shadow data from May 28th 2010 are marked with a grey 
background colour while the periods before and after have a white background 
colour and can still be edited.

 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 62 
4.9 Reference Curve Editor 
The Reference Curve is a corner stone in the report module as it forms the basis 
of a number of expected production calculations. It is also possible to create 
wind distribution curves, which can be used in efficiency reports (Power curve 
module). 
 
The Profile Administrator sub-module contains a reference power curve editor, 
which can be used to create and edit reference curves. 
Creation and modification of reference curves require that the user has special 
access rights. 
 
 
 
The window of the Reference Curve Editor is opened by clicking the 
icon in the toolbar of the basic administrator window shown in Figure 
48. 
 
 
Figure 67 - Reference curve editor window 
The left hand side of the area in the Reference Curve Editor window contains a 
list of the available reference curves, a text box with a descriptive text for the 
reference curve selected in the list above, information about whether the 
selected reference curve is locked (cannot be edited) and information about the 
air density for which the selected reference curve is valid. 
 
Profiles containing wind turbines need a reference curve so if the list of 
reference curves is empty; a reference curve has to be created before a profile 
containing wind turbines is workable. 
 
The Add New button is used for adding a new reference curve. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 63 
Edit is used for the editing of an existing reference curve. 
 
The Delete button is used for deleting a reference curve. Deletion of a reference 
curve cannot be done if the reference curve is locked or used in any of the 
profiles defined. 
 
The Interpolate button makes an automatic linear interpolation between non-
zero values in the reference curve table. 
 
The Reference Curve Data table contains the power output in kW for all wind 
speeds from 0 m/s to 30 m/s in steps of 0.1 m/s, 0.5 m/s or 1.0 m/s. The Filter 
Wind speed Values drop-down box controls the “size” of the steps. 
 
The Generate Weibull button allows wind distribution curves to be made based 
on 2 Weibull parameters and a y factor that is multiplied with the function 
showed at the bottom of the window. 
 
 
Figure 68 - Example of Weibull generation of wind distribution curve 
The selected reference curve is presented graphically at the right hand side of 
the window. 
4.10 Creating a reference curve 
To create a new reference curve, click the Add New button. 
Select the curve type “Power reference curve” or “Wind distribution curve”. 
 
Enter the title of the new reference curve in the Curve Title field. In the 
Description field a text may be entered (optional). 
 
The Cut-in / Cut-out fields let you specify when the wind turbine pauses due to 
low and high wind speeds. 
 
The Air Density field will per default hold 1.225 kg/m3. If needed, enter the 
actual value for the new reference curve. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 64 
 
Figure 69 – Selecting reference curve type 
It is very important thatthe correct air density is entered as the results 
generated by the report module are strongly influenced by the reference curve 
air density. 
 
The Lock Curve for Changes check box should not be selected at this point 
because this will prevent reference curve data from being entered! 
 
Click OK to close the window. 
Inserting power/bin values for a reference curve 
Next step is to enter the power output for each wind speed value. Normally, 
power output values are available for integral m/s - values such as for 0, 1, 2, 3 
…. m/s wind speed. If these values are entered, the Interpolate button may be 
used for obtaining an automatic interpolation between all the non-zero power 
values entered. All power values lying before the first non-zero power value 
and after the last non-zero power value will remain equal to zero. 
 
It is of course possible to insert power output values for all the individual wind 
speeds but this is a time-consuming process. 
 
The graphical area at the right hand side of the Reference Curve Editor window 
is updated concurrently with power values being entered. This makes it easy for 
you to check whether the correct reference curve values are being entered. 
When you have entered the power values and interpolations have been made, 
click the Apply button to transfer the new reference curve to the database. 
Copy-paste of power output values from Excel 
You can also copy-paste power output values from an Excel spread sheet. 
 
In Excel, select two columns with wind speed and power output values; copy 
this information. Then select a cell in the kW column in the Reference Curve 
Data table and paste the information from Excel into the columns. Finally, use 
the Interpolate button to create the reference curve. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 65 
The values from the spread sheet will be assigned to the correct wind speeds in 
the reference curve automatically. This way it is not necessary to include all 
wind speed values in the spread sheet list. 
 
 
Figure 70 – Excel Figure 71 – Reference curve editor 
4.10.1 Locking a reference curve 
It is possible to lock reference curves and thus prevent subsequent 
modifications of the reference curve. To do this, click Edit and check off the 
Lock Curve for Changes check box. 
 
A locked curve cannot be unlocked by the user, only the system administrator is 
able to do so. If the user then confirms that the curve shall be locked, the locking 
is made. The status shown in the Reference Curve Editor window (Figure 67) 
will then change from Open to Locked. 
4.11 Setup of validation parameters 
The report module performs validation of both the data received from the units 
and the manually inserted values. Hence, the Profile Administrator has a special 
function that allows users to change the validation parameters and to 
activate/deactivate the individual validations. Special access rights are required 
make changes in the validations. 
 
 
To open the Validation Parameters window, click the icon in Profile 
Administrator window shown in Figure 48. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 66 
 
Figure 72 – The validation window 
4.11.1 Selecting group or unit type parameters 
A selector is placed below the toolbar to let you select the validation parameters 
to be shown/edited. A click on the down-arrow to the right in the selection field 
opens a menu from which parameters can be selected. 
 
The list contains all the unit types. At the top a special group with the 
meteorological parameters, which are common for the whole site is found. 
When the group or unit type is clicked in the list, the related parameters are 
shown. 
 
A red check mark in the Active column indicates that the validation is active. 
The name of the unit is stated in the Entity column and to the right the lower 
and the upper validation limits are stated. 
4.11.2 Editing validations 
In order to be able to edit validations, the user must have the appropriate access 
rights. 
 
To activate/deactivate, click the leftmost field in the row. This will make the red 
check mark appear or disappear. When changes have been made, click the 
Apply button. The transfer of the change is confirmed by the Apply button 
being greyed out. 
 
To change the lower and upper limits left-click on the limits to be changed. 
Enter the new limit values and transfer the changes to the database by clicking 
the Apply button. In addition, here, greying out of the Apply button confirms 
that the changes have been transferred to the database. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 67 
4.11.3 Shadow data regeneration after validation changes 
The validation changes will automatically be used on future data but for the 
existing data to be validated in accordance with the new validation parameters, 
a regeneration of the shadow data is necessary. For a description on 
regeneration of shadow data, see section 4.7. 
 
Changes in the group of meteorological parameters have impact on all the 
profiles made for the site. Hence, shadow data for all profiles may need 
regeneration as each profile has its own set of shadow data. 
 
Changes in validation parameters for a unit type have impact only on the 
profiles containing this unit type. Only these profiles may need shadow data 
regeneration. 
 
The green plus-sign changes to the red minus-sign in front of those profiles, 
which need a shadow data regeneration to have the validation changes to take 
effect also on the existing shadow data. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 68 
4.12 Profile and template access 
The administrator for the report module has a user access setup facility, which 
is used for administration of the user access rights to profiles and report 
templates. 
 
 
The Profile and template access setup facility is started by clicking the 
icon in the Profile Administrator window shown in Figure 48. 
 
The Profile & Template Access window has two tab sheets one for profile access 
and another for template access. 
 
 
Figure 73 – Window for assigning access rights 
The user roles or individual users are shown in the left column; the report 
profiles or templates in the center column while access is indicated in the 
Enabled column by a checkmark. The user creating the new profile may now 
add check marks for the users who shall have access to the new profile. 
 
The information is transferred to the database when you click the floppy disk 
icon (Save) in the toolbar or the window is closed. 
 
The user cannot change his or her own access rights. An attempt to do so will 
result in an error message from the system administrator. 
 
Note: You can see the report profiles and report templates that YOU have access 
to. A special permission is required for setting permissions for other users. 
Contact your system administrator for access rights. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 69 
4.13 Free wind parameter setup 
The Free Wind Parameter Setup contains a number of correlation parameters, 
which can be set up for one or many parameter configurations. The correlation 
parameters can be attached to a park unit in the park unit configuration 
specifying how to calculate the free wind speed. 
 
 
Figure 74 – The Free wind parameter window 
 
The Free wind parameter setup facility is started by clicking the icon 
in the Profile Administrator window shown in Figure 48. 
 
If you click the remove button, the selected correlation parameters are removed. 
Clicking the Add and Edit buttons activates the window shown in Figure 48 - 
The basic window of the administrator sub-module . 
 
 
The High Pitch angle must always be 
smaller than theLow Pitch angle. 
 
Interpolation is performed using the 3rd 
order polynomial parameters. 
 
The 3rd order polynomial is applied on the 
wind turbine anemometer wind speed. 
 
Note: IF wind exclusive sectors are applied, the 
specifications in the Free wind parameter setup 
will be overwritten. 
 
Click OK to save and close the window and 
Cancel to close the window.

4.14 Wind exclusion sectors 
The data in a wind sector group is used in the calculation of free wind speed for 
the shadow data. Additionally, wind exclusion sectors can also be used for the 
calculation of power curves. 
 
A wind sector group can be defined by means of a number of wind sectors. A 
wind sector group can be attached to a wind turbine in the Park Unit 
Configuration window – see Figure 52. 
 
Note: Be sure to cover the full 360 degrees! 
 
 
 
Figure 76 – Creating wind exclusion sectors 
The following window appears when you click the Add or the Edit buttons. 
 
 
Figure 77 – Definition of wind exclusion sector 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 71 
 
Excluded: Select this option to exclude a wind sector which means that the 10-
minute data from wind directions within the specified sector will not be used in 
the calculations. 
 
The excluded wind sectors can also be applied to the calculation of power 
curves if the Include WSG (Wind Sector Group) option is selected in the Power 
Curve window (see chapter 13 in the VestasOnline Business Operator’s Manual 
for more information). 
 
Angle: A start angle and a stop angle can be defined for a sector. The example 
shows that the start angle is included and the stop angle is excluded. 
Parameters: The parameters in the last part are used in the calculation of free 
wind speed. 
 
The Run parameters are applied when the rotor of wind turbine is running and 
creating turbulence; the Stop parameters are applied when the rotor is not 
moving. 
 
Note: Wind Exclusion sectors include the 3rd order polynomial and will overwrite any 
existing parameters in the Free Wind parameter setup. The 3rd order polynomial is 
applied on the wind turbine anemometer wind speed.

Chapter 5 Calculation Procedures 
This chapter describes the calculation formulas behind the report columns used 
by the VestasOnline®Business Report Module. 
 
The report column descriptions provide a detailed explanation on how results 
are calculated together with a description of resolution and uncertainty. 
 
The VestasOnline® Business Server database operates with two main data tables 
for data storage. The tables are the following: 
 
 Collected 10-minute data from the wind turbines (raw data tables) 
 Auto-processed and manually entered data (shadow data tables) 
 
5.1 Collected 10-minute data from the wind 
turbines 
The collected data from the wind turbines are processed, time stamped and 
stored in a local 10-minute database in each wind turbine controller. The Data 
Collection Module (DCM) installed on the VestasOnline® Business Server 
collects the data packages every 10 minutes from all wind turbines and stores 
these packages in the central SQL Server database. The number of values in 
each 10-minute data package is dependent on the type of wind turbine. 
 
Note: The 10-minute data collected from the wind turbines are never manipulated or 
post-processed in any way. 
5.2 Automatically processed and manually entered data 
Shadow data are auto processed and manually entered. The auto-processed 
data are used for pre-calculations of complicated expected outputs of the wind 
turbine, downtime allocation and of free-stream wind speeds. 
5.2.1 Auto-calculated shadow data 
The following data are automatically calculated and stored as shadow data for 
each wind turbine: 
 10-minute average wind turbine expected output based on the reference 
curve with air density correction using the wind turbine anemometer 
 10-minute average wind turbine expected output based on the reference 
curve without air density correction using the wind turbine anemometer 
 10-minute average wind turbine expected output based on the reference 
curve with air density correction using the meteorology anemometer 
 Wind turbine free-stream wind speed using the 10-minute average wind 
speed measured on the wind turbine applied with a 3rd order correction 
polynomial 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 73 
 Downtime category according to event information collected from the 
wind turbine (e.g. Manufacturer, Owner, Substation, etc.) for all 10-
minute values based on the event allocation table entered into the Profile 
Administrator module 
 Downtime category based on manually entered status/event 
information, which has been entered to overwrite existing information 
from the wind turbine or to fill in information gaps due to data loss 
5.2.2 Manually entered shadow data 
To ensure 100% database integrity it is necessary to add manually entered data 
into the database. In case a wind turbine loses power for an extended time 
period, the normal 10-minute data cannot be generated and the data will be 
missing in the database. Part of the database integrity procedure is to ensure 
that all 10-minute periods hold valid data for: 
 
 Actual average production (kW) 
 Free-stream wind speed (m/s) 
 Status code 
 Category (Normal operation – Manufacturer – Owner – Substation – 
etc.) 
 Expected output (kW) 
 
The following data can be manually entered into the shadow data tables for all 
wind turbines: 
 Average free-stream wind speed 
 Average production 
 Status code 
 Category 
 Expected production 
 Blade pitch angle (applies only to certain wind power plants with 
passive stall wind turbines from the former NEG-Micon turbine range) 
 Comments (used for documenting manually entered data) 
 
Note: The 10-minute data stored in the shadow data tables will always be manipulated 
or processed data. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 74 
5.3 Reporting process work flow 
The reporting process involves all sub-modules in the Report Module. 
5.3.1 The Report Generator module 
The Report Module includes five different sub-modules in the reporting 
workflow: 
 The Report Archive is available for all users who can access archived 
reports 
 The Report Generator is available for all users who can generate reports 
 The Template Designer is available for the on-site operator who needs to 
design new reporting templates 
 The Shadow Data Editor is available for on-site operators who are 
responsible for event downtime allocation and database integrity 
 The Profile Administrator is available for the administrator who is 
responsible for the contractual system configuration. The module 
includes event allocation list, wind turbine neighbour setup, power 
reference curve, allocation category setup, report template user-rights 
and raw data validation parameters 
5.3.2 The reporting work flow 
The reporting process consists of a number of different steps and processes. In 
the following, the different stages will be described: 
Collected 10-minute data 
The raw data have been collected from the wind turbines and stored in the SQL 
Server database. 
Auto-generating shadow data 
The shadow data are generated for all wind turbines with a 10-minute 
resolution based on the configuration in the Profile Administrator. 
Profile Configuration (Profile Administrator) 
The contractual information such as power reference curves and downtime 
allocation is made available for the auto-generatedshadow data. 
Shadow data 
The auto-generated shadow data have been stored in the wind turbine shadow 
data tables in the SQL Server database. 
Manually entered shadow data (Shadow Data Editor) 
The Shadow Data Editor is used for validating the collected 10-minute data. The 
manual database integrity procedure is executed and all necessary data are 
entered into the shadow data tables. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 75 
Generating results and storing them in a new report table 
Reports are generated by means of combined data from the collected 10-minute 
raw data and the shadow data. In combination, these merged data offer a 
database with full integrity. 
Report template configuration (Template Designer) 
The generated reports use the predefined template, which has been set up and 
configured in the Template Designer. 
Report results (Report Generator) 
A report result table is generated and stored in the SQL Server database. 
Extracting reports (Report Archive) 
Already processed reports can be presented, edited, re-calculated or removed. 
Reports 
Reports can be copied to a spread sheet, printed on paper or to a PDF file. 
 
 
Figure 78 – Diagram of report generation 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 76 
5.4 Reporting data basis 
Report columns available in the Template Designer all use data from the SQL 
Server database tables. All generated reports are based entirely on shadow data 
tables and/or the collected 10-minute data tables (raw data). 
5.4.1 Combining shadow data and collected 10-minute data 
The philosophy in combining shadow data and collected 10-minute data is 
prioritization. 
An example of prioritization is the reported wind turbine wind speed 
information, which is presented in three ways: 
 
 1) The actual wind speed measured at the wind turbines (collected 10-
minute raw data) 
 2) The free-stream wind speed which is automatically calculated using a 
3rd order polynomial 
 3) The manually entered wind speed which is added to the shadow data 
using the Shadow Data Editor 
 
All three above values may exist in the tables but only one of the above value 
types is allowed to be used in the reporting process. 
In this case the order of priority is 3 > 2 > 1, meaning that manually entered data 
always have the highest priority and will be used for reporting when they are at 
hand. 
 
If no manual data are entered into the shadow data table, the free-stream wind 
speed will be used. If the free-stream wind speed has not been calculated, the 
collected data will be used. 
5.4.2 Shadow Data Details 
The Shadow Data Details menu in the Shadow Data Editor can be used for 
viewing detailed information on shadow data and collected 10-minute data. The 
table contains several values per wind turbine for each 10-minute period. 
 
The Shadow Data Details screenshot shown in Figure 79 is an example of one 
10-minute period from the wind turbine A1. Note that the values present in the 
Shadow Data Details window differ depending on the selected report profile for 
a turbine, i.e. whether the turbine has an AOM 4000 or AOM 5000 service 
contract. For AOM 5000 contracts an additional line: 42 – Average actual 
production – is added. For further information, see section 2.6 Editing and 
presenting shadow data. 
 
The lines in the data table are colour coded to illustrate the different types of 
data. On the screen, the different colours will appear more distinct. For a 
description of the different colour codes, see Figure 21 in chapter 2. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 77

42 is not present in shadow data for AOM 4000 turbines. 
Note: ADC (appears in line 39-41) is an abbreviation for Air Density Correction 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 78 
5.4.3 Priorities used in the reporting process 
In the following section, all priorities used in the reporting process are 
explained. 
5.4.4 Expected production priority 
The priority for calculating expected production used in the reports and 
calculations is given as follows in the Shadow Data Details window: 
 
 For turbines with an AOM 4000 service contract: line 42 (37, 38, 40, 41, 
39) – see table 3 
 
 For turbines with an AOM 5000 service contract: line 43 (37, 38, 40, 41, 
39, 42) – see table 4

turbines of the same type (except production from the actual 
turbine, primary and secondary neighbour turbines and de-
rated turbines).

reports on Lost or Expected production 
Table 4 - Expected production values with priorities (AOM 5000) 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 79 
The value presented in the Expected production line (42 for AOM 4000 / 43 for 
AOM 5000) and hence used in reports and calculations is taken from the highest 
priority line of the lines containing valid values. 
Line 38 contains the production from a neighbouring wind turbine or – if the 
neighbouring turbine has been de-rated – the expected production for the 
neighbouring turbine. The use of the production data from a neighbouring 
wind turbine is optional. Each wind turbine can be set up in the Profile 
Administrator to have two neighbours; a primary and a secondary. The 
validation and priority of wind turbine neighbours is auto-calculated and stored 
as shadow data - see line 6 in Figure 79. 
Often, the wind turbines selected as neighbours are placed close to the wind 
turbine but a neighbour can also be situated further away. The important thing 
is that neighbouring wind turbines have similar wind and terrain conditions. 
To secure the highest degree of data integrity, it may be advantageous to select 
the secondary neighbouring wind turbine from a separate communication loop 
or feeder, if available. This will secure data for expected production if the grid 
connection is lost for parts of the wind power plant. 
5.4.5 Wind speed and priority

5.5.3 Calculation of Standard Contractual Availability 
The Standard Contractual Availability is based on the event codes of the 
collected 10-minute data. The event categorisation is set up in the Profile 
Administrator according to the contractual settings. 
 
This report column contains a calculation of the Vestas Standard Contractual 
Availability using the generic formula: 
( TA / TCT ) * 100%, 
where 
 
 - TA means "Turbine Available" and shall be the accumulated number of hours 
the WTG is operating or ready and available for operation for any given period 
according to allocation of turbine events into categories in the VestasOnline 
Business SCADA system. 
 
 - TCT shall mean the "Total Calendar Time" in hours of the calculation period 
(i.e. for availability on an annual basis TCT = 8760 hours). 
Downtime allocated to other categories than Manufacturer and Unscheduled 
Maintenance is not considered as WTG errors and is included in TA. TA is 
though calculated as "TCT - T,Manufacturer - T,UnscheduledMaintenance", 
where 
 
 - T,Manufacturer is the downtime hours due to turbine events allocated to the 
Manufacturer category 
 - T,UnscheduledMaintenance is the downtime hours due to turbine events 
allocated to the UnscheduledMaintenance category 
5.5.4 Calculation of Manufacturer Loss kWh 
Manufacturer Loss in kWh is calculated as a summation of the difference 
between the expected production and the actual production divided by 6 
(conversion from kW to kWh) for all 10-minute periods having the 
Manufacturer category. 
 
Description of the expected production calculations is found in section 5.4.4, 
and the calculation of actual production is described in section 5.5.12. 
5.5.5 Calculation of Normal Operation Hours 
Normal Operation Hours are calculated as the sum of periods having the 
Normal Operation event category within the report period. 
 
The resulting number of seconds is converted into hours after summation. 
5.5.6 Calculation of Normal Operation Percentage 
Normal Operation Percentage is calculated as the ratio of Normal Operation 
Hours to the reporting period (TCT). 
 VestasOnline® Business 3.9 – Advanced ReportingModule Administration Manual Page 84 
5.5.7 Calculation of Manufacturer Downtime Hours 
Manufacturer Downtime Hours are calculated as the sum of periods having the 
Manufacturer event category within the report period. The calculation 
procedures do not distinguish between events causing a wind turbine to stop 
and events not causing a wind turbine to stop (Warnings). All periods having 
the Manufacturer category are included in Manufacturer Downtime Hours. 
For periods having the Manufacturer category based on the event code from the 
wind turbine, the time used for summation is the value in line 20 (see Figure 79 
– Example of Shadow Data Details), which varies varies between 0 and 600 
seconds. 
For periods where the Manufacturer category is either entered manually or 
based on a manually entered event code, the time used for the summation is 
always 600 seconds. 
 
The resulting number of seconds is converted into hours after summation. 
5.5.8 Calculation of Manufacturer Downtime Percentage 
Manufacturer Downtime Percentage is calculated as the ratio of Manufacturer 
Downtime Hours to the reporting period (TCT). 
5.5.9 Calculation of Missing Allocation Hours 
Missing Allocation Hours are calculated as the sum of periods having the no 
event allocation within the report period. 
The resulting number of seconds is converted into hours after summation. 
5.5.10 Calculation of Missing Allocation Percentage 
Missing Allocation Percentage is calculated as the ratio of Missing Allocation 
Hours to the reporting period (TCT). 
5.5.11 Calculation of Average Free-Stream Wind Speed m/s 
The Average Free-Stream Wind Speed in m/s is calculated as the average of the 
wind speed values in line 11 (see Figure 79 – Example of Shadow Data Details) for all the 
10-minute periods of the report period. 
The wind speed value in line 11 is, as taken in order of priority: 
1) Wind speed manually edited (line 8) 
2) Free-stream wind speed (line 9) 
3) Actual wind speed (line 10) 
 
Priority 1 is simply a manually inserted value while priority 3 is the actual 
average wind speed received from the wind turbine. Priority 2, the free-stream 
wind speed, is a wind speed value derived from the actual wind speed by 
means of a set of correlation expressions, as described below: 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 85 
Calculation of the free-stream wind speed for wind turbines in 
operation 
The relation between the actual wind speed and the free-stream wind speed can 
be established as a third order correlation expression:

kAWSkAWSkAWSkFSWS  
 
where FSWS is the free-stream wind speed in m/s and AWS is the actual wind 
speed in m/s. 
 
Stall regulated wind turbines 
For a wind turbine in operation the set of constants depends on the pitch angle 
of the wind turbine blade1, so the calculation procedures have room for two 
correlation expressions for each shadow database, valid for two different pitch 
angles. 
 
Figure 80 – Free wind parameters 
By means of these two correlation expressions and the pitch angle of the wind 
turbine, which can be found in line 48 (see Figure 79), it is possible to calculate 
the set of correlation constants valid for that wind turbine by 
interpolation/extrapolation. 
 
 
1 Stall-controlled wind turbines operate with a constant pitch angle of the blades but the pitch angle will normally vary as the 
optimal pitch angle depends on the surroundings of the individual wind turbines. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 86

The expression above is used if the generator status code is equal to 1, meaning 
that the generator was connected to the grid during the whole 10-minute 
period. 
Calculation of the free-stream wind speed for wind turbines not

For a non-producing wind turbine a single correlation expression independent 
of the pitch angle is used:

This formula is used when the generator status code is equal to 0, meaning that 
the generator was not connected to the grid during the whole 10-minute period. 
Calculation of the free-stream wind speed before correlations have 
been established 
It requires some months of operation to collect sufficient data to establish the 
correlation expressions. Until the correlations are ready, the free-stream wind 
speed calculation is suppressed by using constant sets of the form k3=0, k2=0, 
k1=1 and k0=0. 
 
Using such a set of constants in all correlation expression causes the free-stream 
wind speed to be calculated as: 
 
AWSFSWS  
 
 
AWS, the wind speed based upon the wind turbine anemometer, approximates 
because of the conversion formulas in the wind turbine controller the free-
stream wind speed. Hence, reasonable results are obtained also in the first part 
of the operating period where the third order correlations have not been 
determined yet. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 87 
5.5.12 Calculation of Actual Output kWh 
The calculation of Actual Output in kWh is based upon the average kW for each 
10-minute period. The average kW (the production) is taken from line 14 (see 
(see Figure 79 – Example of Shadow Data Details). 
The actual output for each wind turbine is calculated as the sum of the 
production values for all 10-minute periods of the report period. Conversion of 
kW to kWh is done by a division by 6. 
5.5.13 Calculation of Operating Net-Expected Energy kWh 
Operating Net-Expected Energy, kWh is used in the calculation of the 
theoretical operating efficiency (see section 5.5.15). 
 
The calculation of the Operating Net-Expected Energy in kWh is based upon the 
Expected reference production WTG anemometer with air density correction in 
line 40 (see Figure 79 – Example of Shadow Data Details). No other lines with 
expected production can be used, not even the lines 37 and 38 which have 
higher priority. 
 
A 10-minute period is excluded from the calculation if the user manually 
changes wind speed, air temperature, air pressure, actual output, event code 
and category or if the wind turbine has not been in normal operation during the 
whole 10-minute period. A 10-minute period is furthermore excluded from the 
calculation if the data received from the wind turbine or meteorology station are 
invalid. 
 
Contributions to the operating net-expected energy kWh from 10-minute 
periods fulfilling the above requirements are calculated and converted to energy 
through a division by six and then summed. 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 88 
5.5.14 Calculation of Load Factor 
The Load Factor is based upon the actual production of the wind turbine in the 
report period in kWh together with the production, which would have been 
produced if the wind turbine had been operating at rated power during the 
whole report period. 
 
The following example illustrates how the Load Factor is calculated: 
 
The report period is assumed to be one week (168 hours) and the rated power of 
the wind turbine is assumed to be 900 kW. Hence, if the wind turbine had been 
producing at rated power during the whole report period, a total of 151200 kWh 
would have been produced. If the actualoutput for the report, calculated as 
described in 5.5.12, is 28000 kWh, the Load Factor will be the following: 
 
%.%FactorLoad 5218100
151200
28000
 
 
The Load Factor is influenced both by wind turbine stops because of 
disturbances and by the wind resources available in the report period. A load 
factor of 100% requires so much wind during the report period that the wind 
turbine has been able to run at full load all the time. In practice, Load Factors of 
more than 50% are extremely rare. 
5.5.15 Calculation of Operating Efficiency 
The Operating Efficiency for the report period compares the measured 
production in kWh to the operating net-expected energy (the theoretical 
expected output). This means that if an event (untwisting, wind vane error, etc.) 
has stopped the wind turbine and the actual output is zero or lower, the 
expected output is calculated based on the wind speed from the wind turbines 
or the meteorology mast. 
 
The sum of measured production in kWh and the sum of operating net-
expected energy for all 10-minute periods with normal operation in the report 
period are calculated. The operating efficiency for the whole report period is 
calculated as the sum of measured production in percent of the sum of 
operating net-expected energy. The Operating Efficiency is based on original 
wind turbine and manually entered data. 
5.5.16 Calculation of Power Curve Efficiency 
The Power Curve Efficiency is a traditional presentation on how the wind 
turbine performance compares to the guaranteed power curve. This means that 
the data used in the efficiency column are all the data where the wind turbine 
was connected to the grid for the entire 10-minute period, no faults, etc. 
 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 89 
The power curve efficiency for the whole report period is calculated as the sum 
of the measured production in percent of the sum of operating net-expected 
energy. Everything that is questionable (manually entered data etc.) is excluded 
from the calculation in order to get a correct picture. 
5.6 Report Columns and Calculation – Energy-Based 
Availability 
The following provides an overview of the available report columns for Energy 
Based Availability (applying to wind turbines with AOM 5000 service 
contracts). In addition, the formula for calculating Energy Based Availability is 
given, including an elaboration of the concepts of availability and production. 
5.6.1 Wind turbine reporting columns 
 
Available Report Columns in Energy Based Availability 
Actual Production WindAware Actual production in kWh when wind 
speed is between the cut-in and cut-out 
wind speed, excluding the turbine’s 
consumption of energy (‘WindAware’). 
Actual Production Actual production in kWh for each of 
the following turbine event categories: 
Utility, Owner, Manufacturer, Scheduled 
Maintenance, and Unscheduled 
Maintenance. Note: The calculation of 
Actual Production corresponds to the 
calculation of Actual Output used for 
Standard Contractual Availability 
(turbines with AOM 4000 service 
contracts). See 5.5.12 above. 
Expected Production Expected production in kWh for each of 
the following turbine event categories: 
Utility, Owner, Manufacturer, Scheduled 
Maintenance, and Unscheduled 
Maintenance. 
Note: The calculation of Expected 
Production corresponds to the 
calculation of Operating Net-Expected 
Production used for Standard 
Contractual Availability (turbines with 
AOM 4000 service contracts). See 5.5.13 
above. 
Possible Power WMS 
Reduction 
Value in kWh calculated by the turbine 
controller as an estimation of the 
possible power that the turbine can 
produce in the given environmental 
condition for the turbine event 
categories Utility and Owner. 
Calculated when the turbine is de-rated 
and running in external power reduction 
mode imposed by a power regulation 
unit. 
Energy Based Availability: The total energy-based availability in 
% for the report period (see formula in 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 90 
5.6.2 below). 
 
5.6.2 Calculation of Energy-Based Availability 
 
Energy-Based Availability is based on the event codes and power reduction 
modes of the collected 10-minute data. The event categorisation is set up in the 
Profile Administrator according to the contractual settings. 
 
This report column contains a calculation of the Vestas Energy-Based 
Availability using the formula:

where 
 
 Available Production indicates the actual energy produced (in MWh) by a 
turbine during an availability period, plus the expected production 
registered by a reference measurement (e.g. primary neighbouring 
turbine) during each assumed available period during the availability 
period. 
 
 Unavailable Production indicates the expected production (in MWh) 
registered by a reference measurement during each unavailable period 
for a turbine during an availability period. 
 
The concepts of availability period and production are further explained below. 
 
Availability Period 
As seen from the above formula, availability is calculated based on an 
availability period and the energy produced during the availability period. Every 
10-minute timestamp in the period is allocated to a sub-period (see below). Any 
period that does not fall with any of the below definitions is considered as a 
normal operation period. 
 
Assumed Available Period 
An Assumed Available Period is a period where the turbine is not able to operate 
or is de-rated due to events such as downtime which the customer (owner) or 
the grid operator (utility) is responsible for. 
 
Excluded Period 
An Excluded Period is a period where the turbine is not able to operate or is de-
rated due to unforeseen events such as Force Majeure, Environmental 
(lightning, hail storms, ice, etc.), and corrupt or loss of data. As such events 
 VestasOnline® Business 3.9 – Advanced Reporting Module Administration Manual Page 91 
cannot be attributed to a responsible party, excluded periods are not included in 
the calculation formula. 
 
Unavailable Period 
An Unavailable Period is a period where the turbine is not able to operate or is 
de-rated due to an event that does not fall within any of the above two 
categories. Scheduled Maintenance is an Unavailable Period, as are other 
periods where downtime is caused by Vestas. 
 
Production 
Production values are calculated based on the above specified periods and 
events. 
 
Available Production 
Available Production consists of two elements: 
 Actual energy produced during the availability period 
 Expected production from any Assumed Available Period during the 
availability period 
 
Unavailable Production 
Unavailable Production is the production that would have been expected in any 
Unavailable Period during the Availability Period (i.e. the turbine was not 
operating or was de-rated because of Vestas).
