摘要
光纤纵联保护在电网中得到较为广泛的应用,在实际运行中PSL600G系列光纤纵联保护暴露出了存在的不足和软件设计中的缺陷。针对PSL602GC光纤允许式纵联保护的方向元件与弱馈功能的配合关系存在的问题,易造成保护装置误动,以及PSL603GF光纤差动保护装置无监测通道是光纤自环、还是通道正常通讯的手段易引起保护装置误动两个问题,结合实际运行中发生的故障分析了其产生的原因以及采取的相应措施。确保电网的安全稳定运行。
Optical fiber pilot protection gets more and more widespread application in the electrical network. The PSL600G series optical fiber pilot protection exposed to the existent insufficiency and software design＇s flaw in the actual movement.In view of the two existent questions： protective device is easy to moved by mistake due to the assorted relation between PSL602GC optical fiber permissible type pilot proteetion＇s direction element and weak reactive function, and this mistake movement is caused by the optical fib~ loop or normal communication method in PSL603GF optical fiber differential protection device non-monitored channel. According to the generant malfunction in the actual movement, this paper analyses the reason and takes some relevant measures to guarantee the secure and stable movement of electrical network.
