METHOD AND APPARATUS FOR SIMULTANEOUSLY TESTING A DIGITAL TYPE PROTECTIVE RELAY USED IN TRANSMISSION SYSTEM

摘要

The present invention relates to a method and an apparatus for simulating a transmission system of a digital protective relay used in a power system.;The simulated test apparatus 10 is connected to the 154 KV digital protective relay 108 via the connection cable 111 via the test connection device 109 of the transmission system simulator. The simulation test apparatus 10 includes a key input unit 100 for inputting setting parameters necessary for a setting system, an LCD 101 for graphic display, a microprocessor 104 equipped with an OS, and a memory unit 106 . Since the microprocessor 104 is equipped with an operating system (OS), the microprocessor 104 can execute the system application program (EMTP) itself and apply it to the actual system.
