中文摘要：

以单机组运行耗电费用最小为目标函数,采用动态规划法,对江都站不同型号机组、不同日平均扬程、不同运行负荷组合生成的45种方案,分别按考虑分时电价与不考虑分时电价,进行叶片全调节（变角）优化计算,同时进行相应的常规运行计算,最后以单位提水费用作为分析指标,对不同型号机组变角优化运行效果进行比较分析,其结论为考虑分时电价、长江潮位影响等因素的站群变角优化研究提供决策依据,同时为大中型泵站改造与经济运行提供参考。

英文摘要：

According to 45 combination schemes of different-type pumps in different daily-average lifts and operation loads in Jiangdu Pumping Station,and selecting the minimum electricity consumption cost as the objective function,this paper gives the results of blade-adjusting optimal operations of each scheme with dynamic planning methods in considering time-sharing electricity prices and without.Simultaneously,it gives the corresponding results of conventional operation.Then based on the unit energy consumption cost,the paper gives comparison analysis of the effect of different-type pumps in blade-adjusting optimization operation,the conclusions can offer decision-making for optimization research of pumping stations considering time-sharing electricity prices and tide levels of the Yangtze River,and references for transformation and economical operation of large and medium-sized pumping stations.
