华光潭梯级水电站远方过载切机装置的应用

Application of Remote Overload Shutdown Devices at Huaguangtan Cascade Hydropower Stations

分析了远方过载切机装置安装的必要性和动作原理。当电网线路过载时,有条件地切除华光潭梯级水电站的部份机组负荷,避免了可能出现的全部厂用电失去和输水长隧洞水锤冲击的安全隐患。

This paper analyzes the installation necessity and action theory of remote overload shutdown device.When the circuit of grid is overloaded,shut down the loads of part of the units conditionally in Huaguangtan cascade hydopower stations to prevent the potential safety hazards of the failure of all the auxiliary powers and water hammer effects on long-distance water diversion tunnel
