With the large-scale spread and application of intelligent substation,it has a higher demand on the dynamic performance testing of secondary system under various fault and abnormal situations.Based on real-time digital simulator (RTDS),the dynamic test method for the secondary system of intelligent substation was studied,and the test mode was proposed.Then,the close-loop test scheme was designed for the secondary system of intelligent substation,which could be applied in protection performance test,secondary system special test and station overall test,etc.Finally,combined with the integration test of a 500 kV intelligent substation project,the digital dynamic test was conducted for the secondary system to assess its performance.The results show that the test scheme is scientific and effective.
