梯级泵站能耗大，对其进行优化调度，节能效果显著。结合一梯级泵站的实际，建立了级间无分水任务的梯级泵站优化调度的动态规划数学模型，给出了优化调度图。阐明了改善级间流量配合是提高梯级泵站效率、降低供水能耗的主要途径。 The energy consumption of the cascade pump station is large, and it is optimized and dispatched. The energy saving effect is remarkable. Combined with the actuality of a cascade pumping station, a dynamic programming mathematical model for optimal scheduling of cascade pumping stations without dividing task is set up, and the optimal scheduling diagram is given. It is clarified that improving the inter-stage flow coordination is the main way to improve the efficiency of the cascade pumping station and reduce the energy consumption of water supply.
