Abstract: The two extreme floods occurred in Erdao Songhua river in 2010 and 2013 exerted great influence on design flood of Liangjiang hydropower station, which resulted in the problem of insufficient reservoir flood control capacity. In this paper, the feasibility of flood divided into stages in flood season of Liangjiang hydropower station is analyzed, and the application and effect of flood regulation by stages in actual operation of Liangjiang hydropower station are discussed by inspection of flood regulation results by stages.

Key words: Liangjiang hydropower station, flood divided into stages, flood regulation

摘要： 二道松花江先后在2010年和2013年发生特大洪水，对两江水电站设计洪水成果有较大影响，由此带来了水库防洪能力不足问题。文章分析了两江水电站汛期洪水分期的可行性，并通过对汛期分期调洪成果的检验，表述了分期洪水调度在两江水电站实际运行中起到的作用和效果。
