利用RCS-900系列线路保护远传命令双端联调的方法

Methods for synchronous tests by using remote-transmitted order of RCS-900 series line protection

提出在高压输电线路两侧,不使用时间同步装置触发继电保护试验仪,同步进行模拟线路故障试验的方法。该方法利用RCS-900系列线路保护装置远传命令功能,通过线路一侧手动触发继电保护试验仪、线路保护装置经光纤通道传输远传命令,另一侧线路保护装置接收远传命令、输出开关量触发继电保护试验仪,同步进行模拟线路故障试验,检验线路保护动作逻辑的正确性。分析了试验方法的可行性,提出了同步误差补偿措施和实用化建议。

This paper proposes that both sides in the high-voltage transmission lines do not use time synchronization device trigger relay tester and simulate line fault tests synchronously. Using RCS-900 series line protection remote command function, in the one line side, through triggering relay tester by hand, remote command is transmitted by line protection devices via fiber channel; in the other side, the line protection device is used to receive remote command, the switch output is used to trigger relay tester, then to synchronously analog line fault test and test correctness of line protection action logic. This paper analyses experimental feasibility and proposes synchronization error compensation measures and practical recommendations.
