蒲石河抽水蓄能电站水库冰情研究

Study on Reservoir Ice Regime of Pushihe Pumped-storage Power Station

蒲石河抽水蓄能电站地处严寒地区,冬季水库会发生结冰现象,为保障电站冬季运行,有必要开展电站水库冰情研究。为此,采用资料分析和数值模拟方式,总结了电站水库冰情的形成及消长规律,分析了电站机组运行和水库冰情之间的关系,给出了该电站建议的冬季运行方式,提出了电站水库冬季最大冰厚的计算方法,模拟了电站水库冬季结冰过程,研究成果可供同类工程借鉴。

The Pushihe Pumped-storage Power Station is located in cold area,so it is necessary to study the reservoir ice regime for safeguarding the safe operation of station in winter as reservoir icing.By data analysis and numerical simulation,the formation and growth law of reservoir icing condition of station are summarized,the relationship between unit operation and reservoir icing regime is analyzed,and the winter operation mode of power station is recommended.The calculation method of maximum ice thickness of reservoir in winter is put forward as well as the freezing process in winter is also simulated.The research results can be used for reference to similar projects.
