线路光纤电流差动保护在西藏电网中的应用

Application of Line Optical-fiber Current Differential Protection to Tibet Power Grid

线路光纤电流差动保护动作原理简单,在西藏电网中得到了广泛的应用。介绍常规的线路光纤电流差动保护的数据同步、数据采样,同时介绍了保护光纤通道形式,最后提出了运行中需注意的几个问题。

The actuation principle of line optical - fiber current differential protection is easy, so it is widely used in Tibet power gird. The common data synchronization and data sampling of llne optical - fiber current differential protection are introduced as well as the channel type to protect optical fiber, and finally the points needing attention during operation are put forward.
