白莲河抽水蓄能电站首台机组低扬程下水泵工况抽水断电水力过渡过程研究

Research on Interim Process in Condition of Water-pumping Power Failure under Low Head in Bailianhe Pumped-storage Power Station

通过建立抽水蓄能机组水泵工况抽水断电的数学模型,结合白莲河电站特殊的上库—前池边界条件,研究抽水蓄能电站首台机组低扬程下水泵工况抽水断电的水力过渡过程,探讨上库(前池)水位变化和导叶关闭规律对水力过渡过程的影响。

Base on the special upper reservoir-forebay boundary condition of Bailianhe Pumped-storage Power Station and the mathematical model of the pumped-storage power station in the condition of water-pumping power failure, the interim process of the pumped-storage power station in the condition of the water-pumping power failure under low head is analyzed and studied, meanwhile, the effects on the interim process with the change of reservoir level and the closure nile of guide vane are discussed.
