Abstract

When a fault occurs in power transmission systems, protective relays play a roles of protecting the power system according to there setting values. Therefor, it is important that protective relays have high selectivity and sensitivity by correct setting the involves a large volume of data and is a complicated and very tedious, therefore vulnerable to the human errors. Also, it is very difficult to verify that the relays have correct operating parameters before the fault occurs. This paper porposed a method to testify the reliability of realys by showing the operation response to faults in the simulation of the real power system operation environment.
