乐滩水电厂线路安稳装置增设

Provision of Line Stability Control Equipment for Letan Hydropower Station

按照目前广西电网结构及运行方式,当乐滩水电厂及近区水电机组出力较多时,220 kV乐溯Ⅰ、Ⅱ线任一回线路跳闸,另一回线路过流。为了保证电网安全及乐滩水电厂的送出,充分利用乐滩水电厂的水能资源,因此在乐滩水电厂增设线路安稳装置。

When Letan Hydropower Station and hydroelectric generating sets nearby have much output under the present structure and operation mode of Guangxi power grid, either of 220kV Lesu Ⅰ circuit and Ⅱ circuit trips, and the other bears over current. In order to ensure safety of the power grid and power transmission from the station and to make full use of the station＇s hydropower resources, line stability control equipment is provided.
