摘要
介绍了江苏500 kV双泗变电站保护复用光纤通道概况,将投运中的保护复用光纤通道发生数次通道异常和中断等故障现象归并成4种类型,并对各种类型的故障作出分析,提出相应的解决方案和对策,探讨了500 kV线路继电保护复用通道在设计、施工、运行管理等方面存在的共性问题。
This article introduces the general situation of multiplexing optical channels in 500 kV voltage Shuangsi substation, and induces several channel abnormities and interrupts to four types. Then the causes of these faults are analyzed and the solving schemes and countermeasures against these faults are put forward. At last ,some common problems existing in design,construction,running and administration of multiplexing optical channels for 500 kV line relay protection are discussed.
