【摘要】：利用智能變電站信息共享優(yōu)勢,提出了基于電流差動原理的站域后備保護方法,并開發(fā)了符合IEC 61850標準的智能變電站站域后備保護裝置.為了驗證站域后備保護裝置的工作性能,提出了基于RTDS的全數(shù)字化保護測試系統(tǒng)方案.通過搭建變電站仿真模型,并配置GTNET-SV和GTNET-GSE模塊,完成了站域后備保護裝置的閉環(huán)測試.針對變電站正常運行、站內故障及站外故障等不同工況,測試了保護裝置的動作邏輯和動作時間,其性能指標滿足設計要求.
[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.
