摘　　要：某地三级泵站调度方式常为人工经验调度,泵站运行能耗较大。为减少泵站在凌晨时段叠压供水条件下的运行能耗,降低供水成本,利用水力模型技术与遗传算法对泵站进行两级优化调度,求解得出在凌晨时段满足最不利点用水需求的泵站出口压力。计算结果表明,泵站富裕供水压力降低,水泵调速比得到优化,水泵运行效率提高了7.2%,与实际运行能耗相比节能5.25%,达到了优化运行的目的。One tertiary pump station is often dispatched by manual experience, and the operation energy consumption is high. In order to reduce the operation energy consumption of the pump station under the condition of superimposed water supply in the early morning and reduce the water supply cost, the two-level optimal dispatching of the pump station was carried out by using hydraulic model technology and genetic algorithm, and the outlet pressure of the pump station that met the water demand at the most unfavorable point in the early morning was obtained. The calculation results showed that the abundant water supply pressure of the pump station was reduced, the speed regulation ratio of the pump was optimized, the operation efficiency of the pump was improved by 7.2%, and the energy saving was 5.25% compared with the actual operation energy consumption, achieving the purpose of optimal operation.
