抽水蓄能电站上水库运行条件下冰厚数值模拟研究

Numerical simulation of ice thickness in upper reservoir of pumped storage power station

寒区抽水蓄能电站上水库在冬季运行时,在热力因素和动力因素共同作用下,电站冰层的形成过程十分复杂。本文通过数值模拟方法,模拟某抽水蓄能电站上水库不同运行工况对冰厚的影响,其研究结果可为抽水蓄能电站冬季运行提供指导和参考,对寒区新建抽水蓄能电站冬季运行具有借鉴意义。

When the upper reservoir of pumped storage power station in cold region runs in winter,the formation process of ice sheet is very complicated under the combined action of thermal and dynamic factors.In this paper,the influence of different operating conditions on the ice thickness of the upper reservoir of a pumped storage power station is simulated by numerical simulation method.The research results can provide guidance and reference for the winter operation of the pumped storage power station,and have reference significance for the winter operation of new pumped storage power stations in cold areas.
