光纤通信在继电保护中的应用

Application of Optical Fiber Communication in Relay Protection

介绍了利用光纤通信来进行继电保护的三种方式:光纤纵联差动保护,分相允许式光纤纵联保护,过电压或失灵启动远跳。另外,也分析了两个工程应用实际问题:光纤通道故障检测和光纤纵差保护旁路切换。

At the moment, optical fiber communication is used widely in relay protection. This paper introduces three ways of relay protection based on fiber communication ： fiber current longitudinal differential protection, segregated permissive fiber pilot protection, trip because of over voltage or reject tripping in other side. Besides, this paper also discuss two question in practical engineering. The trouble checking up of fiber passageway and shunt - transfer, this paper can provide technique reference to working personnel in power system designing.
