【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。
[Abstract]:Reservoir operation chart with its simple operation, convenient and intuitive advantages, become a common tool for reservoir operation of the hydropower station guidance, but on the basis of plans to run the routine operation, it is difficult to achieve the optimal scheduling results, to make full use of the operational effectiveness of the reservoir. The reservoir generation scheduling to the full operation of the reservoir, the establishment of a joint power generation optimal scheduling model of cascade reservoirs, and using dynamic programming successive approximation method (DPSA) and dynamic programming (DP) method. Through the nested graph scheduling simulation results and results the power optimization model were analyzed to optimize the rationality of the model was verified, and applying the method of probability statistics and further mining reservoir in flood season the non flood season generation scheduling rules. Study on Application of cascade reservoirs in a basin, optimal operation can achieve better power efficiency, At the same time, the rule of power generation dispatching is of guiding significance to the formulation of the annual scheduling plan for hydropower stations and the actual operation of the reservoir.

【正文快照】： 0引言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[1],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。近年来,水电站水库的优化调度研究成为一个重要课题[2]。同时水电站中长期优化调度可不考虑水流时滞的影响
