Fault analysis of power system. checking of relay and network healthiness.
What you’ll learn
⚡ Requirements for Fault Analysis,
⚡ Comtrade files exporting and saving from MiCOM, Siemens, ABB and DFR.
⚡ Different fault types, tripping from one end or two ends. Simple files, only current , also voltage, two currents.
⚡ Harmonics segregation in different channel for each order during fault.
⚡ OV during fault, different reasons.
⚡ Contribution of Delta connection of power transformer.
⚡ Motor sharing in fault current
⚡ CT and VT double ground effect
⚡ Transformer differential trip after restoration, special case.
⚡ DOC, DEF signal generation of absent components.
⚡ Subsidence effect on BF Protection
⚡ Short time trip signal effect on trip coil.
⚡ BBP delayed trip reasons. BBP didn’t trip with fault inside bus zone.
Requirements
❗ knowledge of SLD, RMOLD, CT ,VT and basics of Power System Protection
Description
Requirements for Fault Analysis, to whom, Any one interested in Fault Analysis with minimum knowledge about Single Line Diagram (SLD), Relay and Metering one Line Diagram (RMOLD), Current Transformer (CT) and Voltage Transformer (VT) location and connection. Data collection for Fault Analysis. Time reference for all data sources.
Comtrade files exporting and saving from MiCom, Siemens, ABB, and DFR.
Test Cases
Simple Cases: Recorder with only current waveform, current and voltage waveforms or two currents waveform. Different fault types, tripping from one end or two ends. new sources feeding CT and VT after tripping from one side only.
Advanced Cases: Harmonics segregation in different channel for each order during fault. Over voltage during fault, different reasons. Contribution of Delta connection of power transformer. Motor sharing in fa ult current. CT and VT double grounded point effect protection system.
Transformer differential trip after restoration, special case. Directional over Current (DOC), Directional Earth Fault (DEF) signal estimation of absent components, phase to phase voltage, neutral current, or residual voltage. Subsidence phenomena effect on protection system specially Breaker Failure (BF) Protection. Repeated short time trip signal (without trip) effect on trip coil. Bus Bar Protection (BBP) delayed trip case study and why it happened. BBP didn’t trip with fault inside zone.
