水电站集水自排技术的探索与实践——以靖西县那多水电站为例

广西靖西县那多水电站原设计为“三井五泵”机电抽排水，运行后发现，所有水泵都正常工作时，可以满足防洪要求，而其中某一套抽水设备发生故障时，电站防洪工作便吃紧。为此，技术人员将排水系统改为集水自流自排式，实现了水电站集水自排系统可靠运行又节约站内用电，还减轻了值班员劳动强度。

Research on and Practice of the Catchments Automatic Drainage Technology --Taking the Example of Naduo Hydropower Station

Naduo Hydropower Station, Jingxi County, Guangxi, has designed the ＂three wells five pumps＂, the mechanical pumping and drainage system. When all pumps works appropriately, it meets the flood control needs. And yet, the flood control work will have problems when one of the pumps fails. The catchments automatic drainage system is reliable and energy conservative and reduces the labor intensity of duties.
