[Abstract]:Taking advantage of the advantages of information sharing in intelligent substations, a method of substation backup protection based on current differential principle is proposed, and an intelligent substation backup protection device in accordance with IEC 61850 standard is developed. In order to verify the performance of the backup protection device in station domain, a full digital protection test system based on RTDS is proposed. By setting up the substation simulation model and configuring the GTNET-SV and GTNET-GSE modules, the closed-loop test of the backup protection device in the station area is completed. According to different working conditions such as normal operation of substation, fault inside and outside the substation, the action logic and action time of the protective device are tested, and its performance index meets the design requirements.
