摘要
介绍了光纤纵联保护的原理、光纤通道作为保护通道的特点和继电保护装置与光纤通道的几种连接方式及各自的时钟设置。根据光纤纵联保护在内蒙古500千伏电网的应用,提出了在运行维护工作中应该注意的几个问题,以提高保护的正确动作率,确保电网安全运行。
The principle of Pilot protection and the connect ways of optic-fiber Channel with Relay protection devices as well their clock settings is introduced in this paper. Based on the application of optic-fiber Pilot Protection in the 500 kV power line at Inner Mongolia, Some issues that should be noted at Routine maintenance work are presented to increase success rate for protection and ensure the safe operation of power grids.
