MiCOM P740 Numerical Busbar Protection IEC 61850-8.1 compliant & 2nd rear port Sales Presentation May 2011 Henri GRASSET Product Manager > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Numerical Busbar Protection MiCOM P740 is: Fast & Constant Constant sub-cycle tripping time (13 ms typical) Flexible & Easy to use Centralised or Distributed solution Dynamic substation replica & monitoring tool PSL (Programmable Scheme Logic) Secure Differential algorithms supervised by multiple criteria (CT supervision, Biased Check Zone, etc…) Delayed tripping algorithm with CT saturation CT saturation detection (< 2ms) Dead zone protection & 50 BF protection Communicating Courier, IEC 103 protocol (via KITZ 274), IEC 61850-8.1 communication protocols Second rear port and InterMiCOM > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Low CT requirements The scheme can be used with many different classes and manufacturing standards of CTs (IEC/BEAMA/ANSI) and can accommodate various ratios (up to 1/40) in the same substation. Due to the low CT burden, the MiCOM P740 can be connected in series with any feeder protection. The MiCOM P740 can be easily integrated into the substation with no dedicated CT cores for the busbar protection. The VTs are optional > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Customer benefits Cost effective solution No dedicated CT reduces maintenance costs, Flexible topology software eases the engineering Reliable operation minimises outages Cost monitoring with: Fault analysis & monitoring tools that ease the commissioning and extensions, etc...) “Backup” protections help to increase the plant life They can be used as normal protections > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Applications The MiCOM P740 numerical busbar protection scheme offers high speed discriminative protection for substation busbars at all voltage levels (MV up to EHV transmission), is suitable for a range of applications such as: Distribution substations Transmission substations Pumped storage hydro electric GIS And for Solid, High Impedance or compensated earthed networks > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * Busbar Protection Overcurrent Protection Commissioning Tools CB & Isolator Supervision Measurements Disturbance Recorder Event & Fault records Programmable Scheme Logic Dead Zone Protection Continuous monitoring PU CT Supervision MiCOM P740 Numerical Bus Relay Features Check Zone Function Keys CB Failure Protection Tricolour LEDs IEC 61850-8-1 or 2nd Rear Port > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Numerical Busbar Protection Architecture > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Architecture The MiCOM P740 scheme is made of: P741 - Central Unit (CU), Gathers and processes the measurements from the PUs, with Ethernet board or 2nd rear port board, hotkeys & function keys and tricolour LEDs (comprises all differential protection algorithms) P742 - Peripheral Unit (PU), Measures and trips, with hotkeys (CT saturation detection, local non-directional overcurrent, local circuit breaker failure protection and Dead Zone protection) P743 - Peripheral Unit (PU), same as P742 but with additional opto inputs, relay output and Ethernet board or 2nd rear port board, hotkeys & function keys and tricolour LEDs P741 - P742 - P743 > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Architecture A MiCOM P740 scheme supports: Per Central Unit: up to 28 Peripheral Units, up to 8 zones (with or without SDEF*), up to 28 feeders. Architecture can be either distributed, centralised or mixed *: SDEF is Sensitive Differential Earth Fault) Maximum configuration > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Architecture The Central Unit (CU) and the Peripheral Units (PU) are mounted in one or more cubicles. This architecture is ideal for the refurbishment of existing substations Centralised Solution > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Architecture The Peripheral Units are installed in individual switchgear bays distributed around the substation The maximum fibre optic length between the Peripheral Units and the Central Unit is 1 km That leads to wiring cost reduction Distributed Solution > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Numerical Busbar Protection Central Unit > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * Numerical Busbar Protection P740 8 Optically isolated logic inputs* Plus 16 virtual inputs 8 Relay ouputs* (Plus 16 virtual outputs) Optional Irig-B board (GPS Time Sync) Modulated or demodulated Up to 7 Communication boards 4 Peripheral Units per communication board 1 Main Processor board & 1 Coprocessor board 22 LEDs (18 three-coloured programmable LEDs) 10 Programmable Function Keys & 2 Hotkeys & back lit LCD 2nd rear port board for additional Courier protocol or Ethernet board for IEC 61850-8.1 protocol * Extended inputs / outputs possible using a P742 or a P743 Central Unit Hardware - Size 19 inches - 4U P741 Central Unit > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Central Unit Main Scheme Differential Elements Check Zone Differential Element Communication Master Scheme Stability and Signal Processing Commissioning Facilities CT Supervision (Circuitry Fault) > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Central Unit Phase segregation + Sensitive Differential Earth Fault A B C N SDEF sensitivity is controlled by phase elements ibiasph idiffph ibiasN idiffN Check Zone biased element [ iinfeed + ioutfeed ] Main Differential Elements Optional Voltage criteria From P923(s) Vx< or Vo> iT iD > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Central Unit Sampling control by saturation detectors (in Peripheral Unit) Algorithm tripping decision before CTs saturation (Max 2 ms) t Biased characteristic against differential errors due to different CTs responses in transient behaviour (before saturation) iT iD Multiple Confirmation Tripping Criteria & 1 4 Circuitry fault detection Stability and Signal Processing > MiCOM P740 - 03/04 - P740C/EN PR/Bf * * MiCOM P740 Central Unit: Trip Logic CU Tripping Logic decisions (for Zone and Check Zone): “Instantaneous Algorithm”: If 2 consecutive samples verify tripping condition (are above (ID>2) and k x Ibias) AND no CT Saturation detected “Delayed Algorithm”*: If all samples verify tripping condition (are all above (ID>2) and k x IBias) during 5.8 ms AND at least one sample does not verify it in the previous 3.3 ms AND at least one sample verified it in the previous 4,2 ms (i.e. an internal fault is detected if a differential current is detected on 2 consecutive half-periods) *: never affected by the CT saturation blocking information.
