Abstract: |
The test structure of traditional RTDS-GTNET is briefly introduced and the practical requirements for the test of protective equipments in smart substation are analyzed. Aiming at the requirements,the updated GTNET-SV module technique is synchronously tracked,the protocol and packet jitter of SV module are compared between new and old versions,and a solution applying the parameter-recognition-and-matching method to realize the normal SV message interaction between RTDS and protective equipment is proposed. With a substation area protection as an example,the implementation of closed-loop test based on GTNET is introduced and the test precision is verified. |
