【摘要】 梯级泵站采用变速调节可以很好地满足各级站之间的水位、流量约束，故运行时的动态配合过程简单，其运行优化问题可以简化为整个提水系统的静态扬程分配问题。本文以整个梯级提水系统的总能耗最小为准则，通过求解动态规划模型来确定各级站的最优扬程和相应的开机方案及各机组的最优转速。更多还原

【Abstract】 Changing speed of pumps can easily meet the restriction in water level and discharge grading pumping stations. Moverover, the dynamic cooperation in the operation of the stations is simple and the optimum operation am be simplified to the optimum dis- patch of the static had of whole pumping system. Tak- ing the consumed energy be minimum as operating criteri- on, the optimum distribution of head, the operating scheme, and the optimum speed of each pump are deter- mined by the solution of the built dynamical program- mined model.更多还原
