动态规划在小型灌溉泵站群布局优化与调整中的应用

Application of dynamic programming in optimization and adjustment of small-scale irrigation pumping station groups

机电泵站的改造与建设规划,必须随着灌区内用地布局的大面积调整而进行优化与调整.采用动态规划法,以泵站为阶段变量,水量为决策变量,泵站群灌溉净效益最大为目标函数,对区域灌溉泵站群进行优化,并根据优化结果提出泵站建设和改造的调整方案,对当前提高农村水利建设资金使用率和水资源利用率具有很重要的意义.通过对淮安市淮涟灌区的优化规划改造,提高了灌区工程的效益,保证了灌溉需求.

The reform and construction planning of mechanical and electrical pumping station must be adjusted along with the adjustment of irrigation area. By using the dynamic planning, and taking the pumping station as the stage variable, the water volume as the decision variable, and the largest irrigation efficiency as objective function, the optimization to the regional irrigation pumping station group is conducted, and the adjustment schemes of the construction and rebuilding of the pumping station are proposed,which is important to the efficient use of water resources in rural area. By the optimization and rebuilding of Huai-Lian Irrigation District, the project efficiency in the irrigation area is improved and the demand of irrigation is ensured.
