摘要:
Abstract: This paper presents the procedure for efficiently preparing the data necessary to perform aPSCAD Relay transient simulation study for relay testing. An existing 1300+ bus ASPEN Oneliner phasor based system model was converted to an equivalent 4-bus
PSCAD Relay model. A comparison of steady state 60 Hz results for both 3 phase and single line to ground faults verify that the transient and phasor system models are
equivalent. The transient model can be used with confidence to generate transient fault waveforms simply not possible to develop with phasor based simulation method. Transient fault waveforms were used toinvestigate the operations of the forward and reverseground directional overcurrent elements of the Nxtphase L-PRO line protection relay.
