泵站可为工、农业用水提供保障，在不同的季节、不同的时间段用水需求不同，所以供水泵站要根据实时的需水要求供水。首先分析了泵站运行的准则，通过选择泵站运行功率最小为准则，针对泵站站内采用逆序递推动态规划法，以某提水工程总干二级为例进行站内优化，优化结果与实际运行相比，其机组组合情况发生变化，单位时间内降低了18.6%的能耗。优化后泵站站内运行情况可根据用水区的需求，保证泵站安全运行的前提下寻求最优的调度方式，提高泵站的运行效率，降低泵站整体运行的成本，最大程度地创造经济效益和社会效益。
Abstract
Pump stations can guarantee industrial and agricultural water. The demand for water is different in different seasons and periods. Therefore, the pump station should supply water according to real-time water demands. Firstly, this paper analyzes the operation criteria of pump stations. The minimum operating power of pumping station is selected as the criterion. The reverse sequence recursive dynamic programming method is used in the pumping station. The station optimization is carried out by taking the second stage of the general trunk of a water lifting project as an example. Compared with the actual operation, the optimization results show that the unit commitment changes. The energy consumption per unit time is reduced by 18.6%. The optimal operation mode can be found according to the demand of water and the premise of ensuring the safe operation of the pump station. It can improve the operation efficiency and reduce the operation cost of the pump station. It can create maximum economic and social benefits.
