摘要
水电站非正常运行情况下,引水系统流量突变往往会引起库区及下游河道涌浪传播,对于有航运要求的水利枢纽,这种涌浪往往会影响引航道附近的水流流场,恶化通航条件。本文建立了库区涌浪计算的平面二维水流数学模型,并应用于凌津滩水电站和琅琊山抽水蓄能电站中,表明该模型具有较强的计算模拟能力。
Under abnormal operation of hydropower station, the flow in the diversion system will suddenly change and result in the wave propagation to downstream channel and reservoir. This often changes the flow field and influences the navigation situation. A numerical model has been developed to simulate this wave propagation in this paper and applied to two examples. The computed results show this model is an effective tool for predicting wave propagation due to flow change.
