摘　　要：选取梯级发电量最大模型,采用具有精度高、收敛快的大系统分解协调算法对模型进行求解,以乌江梯级电站为例,通过对流域不同频率来水情况的发电量进行计算,进而总结了乌江梯级电站短期优化调度的发电规律,为短期调度计划的制定提供了决策指导。For studying the short-term optimal operation of cascade hydropower stations, the maximum cascade power generation model is selected and the model is solved by using large system decomposition and coordination algorithm with high precision and fast convergence. Taking cascade hydropower stations in Wujiang River as an example, the power generations under different runoff frequencies of basin are calculated, and the power generation rule under the scale of short-term operation is summarized, which provides guidance for formulating short-term scheduling plan.
