摘　　要：调水工程中泵站建成后,在不同的时期承担不同的调水任务,为了完成各种调水任务,往往使水泵在不同的工况点运行。基于离散的单级泵站运行工况点,对泵站的流量分配进行了优化研究;在满足水泵流量、扬程和各种水力学条件的约束下,以泵站整体效率最高为目标函数,基于一些工况进行了不同机组流量分配的对比研究,建立了流量优化分配数学模型,得出了各个工况点下泵站内机组流量分配的最优组合。After the pumping st ation of the water transfer project is built, it may carry on different water transfer tasks at differ-ent times. In order to finish water transfer tasks, the pumping stat ion operates under different working conditions. Based on the discrete working points of a single-stage pumping station, flow distribution of the pump station was optimized. To achieve the maximum efficiency of the pumping station syst em, w e established the flow dist ribution optimization model under the con-straints of pump flow, pump assembly head, and number of operating units. Flow dist ributions of different units w ere compared under several working conditions, and the optimal combination of flow distribution of different units in a single-stage pumping stat ion was obtained.
