摘　　要：通过对万家寨引黄工程梯级泵站运行中影响泵站用电量较大的机组、变频器等的深入研究,从泵站能源单耗入手,以单方水耗电量为切入点,推导出尽可能降低总一、总二泵站的扬程和机组定速运行是降低万家寨引黄工程泵站运行能耗的关键因素,并在实践中得以验证。这一结论可以对类似泵站的经济运行提供借鉴和参考。Through our in-depth research on the units,frequency converters,and other factors that have a significant impact on the power consumption of the cascade pumping stations in the Wanjiazhai Yellow River Diversion Project,starting from the energy consumption of the pumping stations,taking the power consumption per cubic meter of water as the starting point,it is deduced that reducing the head and unit speed operation of the first and second pumping stations as much as possible is the key factor in reducing the energy consumption of the pumping stations in the Wanjiazhai Yellow River Diversion Project,and has been verified in practice.This conclusion can provide reference and reference for the economic operation of similar pumping stations.
