中小型灌区排涝泵站优化运行模式探讨

Study on Optimal Operation Mode of Drainage Pumping Stations in Small or Medium Irrigation District

以靖江市孤山灌区为例,依据中小型提水灌区排涝泵站的特点,分别以排涝泵站开机机组总耗能最少、能耗率最低为目标函数,采用按开机机组装置效率最大和动态规划的方法,探讨了在满足特定排涝设计标准下孤山灌区内自成排水体系的竖河大港排水片排涝泵站最优运行方式,对提高中小型提排灌区泵站管理水平,减少能源浪费有一定的指导作用。

According to drainage pumping stations＇ characteristics in small or medium pumping irrigation areas, the paper takes the minimum total energy consumption of start-up units of drainage pumping stations and the minimum energy consumption rate as object functions. By means of the maximum start-up units efficiency of a pumping station and dynamic programming, the paper discusses the optimal operation mode of Shuhe-Dagang drainage area, which is a complete and closed system in Gushan irrigation district in Jingjiang city,under particular drainage design standards. The management level of small or medium drainage areas is improved. The paper offers a reference to reducing energy waste.
