Abstract:
This paper addresses three aspects of testing relay protection systems using a real time simulator: (1) simplify the setup by using low level analog signals to the relay; (2) use a ‘threading’ process when a hybrid setup (commercial relays and simulated relay models) is chosen; (3) test substation protection system together with control and communication systems.
