Abstract

The response analysis program of various protective relay systems has been developed, which program is able to analyze relay systems' responses against power system faults with high accuracy and also to check the setting values and coordination among relay systems.
Various relay systems are simulated by arbitrarily assembling six kinds of elements( relay, logic, timer, etc.). Relay elements are newly classified into 28 kinds of functions by concerning their principles and characteristics, which are able to cover relay systems installed for 66kV and above transmission system.
Voltage and current distribution on power system are calculated using method of symmetrical coordinates which are expanded from the fault calculation part of the power system dynamic analysis program (developed by CRIEPI).
It is confirmed that this program is useful for operation and has enough accuracy for analysis of relay systems through simulations of real power systems at various complex faults.
