| Abstract: | 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. |
