摘　　要：在建立叶片可调式泵站日优化运行数学模型的基础上,选择日运行时段划分方式、日均扬程和日提水量要求作为已建泵站运行工况下的敏感参数,通过分析其变动对泵站运行费用、机组运行方式等的影响,开展敏感性分析研究,探究各参数在叶片可调式泵站日优化运行中的作用,为泵站经济运行和流域泵站系统联合优化调度提供指导。以淮安四站为例进行计算分析,结果表明：①泵站日优化运行,宜考虑峰谷电价,每隔2～4h划分一运行时段。②越接近设计扬程,单位扬程所用电费越少。③日提水量较小时单位提水电费少,经济性更好。A mathematical model for optimal daily operation of single adjustable-blade pump station is proposed in this paper.On this basis,the division manner of operation time,the average pumping head and the daily water volume to be pumped are selected as sensitive parameters,changes of which have influence on the cost of energy consumption and operation mode of unit.Sensitivity analysis of the parameters reflects the important roles they play in optimal daily operation of single adjustable-blade pump station,providing guidance for the economical operation of pump stations and united optimal operation of basin pumping station system.The No.4Huai＇an Pump Station is taken as a case study.The application result shows that：①in optimal adjustable-blade daily scheme,suitable division manner of operation time is considering the electric price in peak-valley loads,managing every 2～4hours as an operation period;②the specific cost per meter pumping head is less when it is closer to the designed average pumping head;③it is economical to pump small water volume in one day,as the specific pumping cost per cubic water is less when the water volume to be pumped is relatively small.
