摘　　要：通过介绍光纤电流差动保护在固原电网中的应用,说明了光纤电流差动保护的动作原理,分析阐述了光纤电流差动保护对通信系统的要求及在运行维护中容易忽视的环节,进而从如何运行维护光纤电流差动保护,保证固原电网安全、可靠运行角度,对继电保护专业技术人员和通信技术人员提出了的新的要求。Through the application of the line current differential protection to the Guyuan power system, this paper illustrates the principle of the fiber optical current differential protection. The communication system requirement and the easily ignorant juncture of running and maintaining for fiber optical current differential protection are analyzed, in the view of the how to run and maintain the fiber optical current differential protection, assure the Guyuan power supply safety, the new requests for relay protection operators and communication operators are put forward.
