Protection Relay Simulation Results
Run simulation with the following fault. line “ELDORDO” 500.0 “LUGO” 500.0 “1 ” is modeled with zonedef and distrelay.
At 1 cycle, apply a 3 phase fault at line “ELDORDO” 500.0 “LUGO” 500.0 “1 “, 85% from the from bus with fault r = 0.01, x = 0.001
Line current “ELDORDO” 500.0 “LUGO” 500.0 “1 “
