SYSTEM FOR TESTING OF DIGITAL PROTECTIVE RELAY FOR MAIN POWER FACILITY ON NUCLEAR POWER PLANT, AND OPERATION METHOD OF SAID SYSTEM

摘要

Disclosed is an operating method of a system for testing a protective relay for a nuclear power plant. The operating method of a system for testing a protective relay for a nuclear power plant comprises: a step where a protective relay performance verification device acquires malfunction waveform data through system modeling for the main power facility in a nuclear power plant; a step where a voltage/current generator uses the acquired malfunction waveform data to generate a real malfunction waveform voltage and current; a step where the voltage/current generator applies the generated voltage and current to the protective relay; and a step where the protective relay performance verification device analyzes transient interaction characteristics of the protective relay to verify performance of the protective relay.
