为提高梯级水库调度管理的科学水平和水资源利用效率，分析了蓄供水判别式法运用于梯级水库调度所存在的三点不足，以梯级调度期总发电量最大为目标，构建了基于梯级总出力调度图优化和时段内最优出力分配的双层嵌套模型，并给出了基于逐步收索方式和逐步优化算法的模型求解流程。以我国西南某流域梯级水库为实例进行计算，其结果与常规方案相比，不仅年发电量有所提高，保证出力和保证率也有较大程度的提升，验证了所建模型的合理性。

In order to improve the scientific level of operation management of cascade reservoirs and the utilization efficiency of water resources , this paper analyzes three shortcomings of discriminant criterion method in the appli-cation of cascade reservoirs operation .With the goal of maximizing total generating capacity in the cascade opera-tion period , this paper sets up a double nested model based on cascade total output dispatching figure optimiza -tion and the optimal period output distribution .The progressive search method and progressive optimality algo-rithm are used in the solving process of the model .Taking a certain cascade reservoir in Southwest China as an example , the power generation and the reliability both have a certain degree of ascension compared with the conventional dispatching scheme .So the rationality of the model is verified by the result .
