Study on the establishment of dynamic performance test environment for the digital protective relay using RTDS

A performance test of digital protective relay is divided into three parts; a static test, a dynamic test, a EMC test. Among these, a dynamic test is increasingly important, but it is not easy to diffuse a technique for dynamic test because of the intricate approach to real time digital simulator. In order to solve these problems, KEPRI(Korea Electric Power Research Institute) has established environments for performance test, which consist of a system model and a performance test procedure for the dynamic test.
