摘　　要：水库调度图以其操作简单、方便直观等优点,成为指导水电站水库运行调度的常用工具,但依据常规调度图运行时,调度结果很难达到最优,难以充分发挥水库的运行效益。针对水库发电调度图难以充分发挥水库运行效益的特点,建立了梯级水库联合发电优化调度模型,并采用动态规划逐次逼近法(DPSA)与动态规划(DP)嵌套方法进行求解。通过调度图模拟结果与所建发电优化模型的结果进行对比分析,对优化模型的合理性进行了验证,同时应用概率统计方法进一步挖掘水库汛期和非汛期的发电调度规律。对某流域梯级水库的实例应用研究表明,优化运行能够获得更好的发电运行效益,同时,发电调度规律对水电站年调度计划的制订和水库的实际运行具有指导意义。The reservoir scheduling chart has already become the guidance for reservoir operating and scheduling thanks to its advantages of being simple, direct and viewable. However, it is hard for the scheduling to achieve optimal results and make full use of reservoirs when operation is performed following the chart. In this paper, aiming at this problem, the model integrating cascade reservoirs with optimized power dispatch is established and solved by adopting dynamic programming successive approximation （DPSA） and dynamic programming （DP） nesting algorithms. Through comparison between the results of scheduling chart simulation and optimized operation, the rationality of the model is verified, and the power dispatch laws in the flood season and the non-flood season are developed by using probability statistics method. The application in the cascade reservoirs of a watershed shows that the optimized operation will achieve better generation benefits, and the power dispatch laws can provide guidance for annual scheduling programrning and reservoir operating.
