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.

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 conaidering 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.
