摘　　要：以南水北调东线源头泵站江都四站为例,建立了考虑峰谷电价的站内多机组日变角优化运行非线性规划模型.以站内机组耗电费用最少为目标函数,时段为阶段变量,水泵叶片角、开机机组台数为决策变量,日抽水量为约束,采用动态规划逐次逼近的方法,对江都四站进行计算分析,确定了不同水量约束条件下泵站机组的开机台数与水泵叶片角.结果表明,该模型可有效解决站内机组优化运行问题,效果良好.A nonlinear programming model （NPM） for the optimal day-operation in Jiangdu No. 4 pumping station with multi-units by adjusting blade angles has been put out, where the peak-valley electricity prices are considered. The NPM takes the minimal operation cost of pump assembly as objective function. In the meantime, the time periods are defined as stage variables. The blade an- gles and the number of the working-pumps are expressed as decision variables and the water volume pumped in one day as constraint condition. Taking use of DP with successive approximation method in optimal operation of Jiangdu No. 4 pumping station, which is the source pump station of eastern route project of south-to-north water diversion, the blade angle and the number of the working- pumps under different water volumes pumped in one day can be obtained. The result of the model shows that the method above can effectively solve the optimal operation of pumping station with multi-units and get good effects.
