摘　　要：针对跨流域调水工程运行线路中经验型闸泵切换启闭形式的问题,选取位于山东省德州市中心城区潘庄引黄灌区马颊河左岸辛店闸至沟盘河水库整条线路为研究区域,基于动态规划的正向递推法,以调水线路经济最优、调水最快为目标函数分别建立2个调水过程模型;利用Python语言对2个调水过程模型进行计算,确定不同运行阶段的闸泵切换方式、开启时刻及开启时长,得到流量与水位相结合的经济优且调水快的闸泵切换优化调度方案。结果表明,沟盘河水库初始水位为影响总运行费用及总调水时间的主要因素,闸泵切换优化调度方案可使运行费用降低20%,总调水时间缩短8%,提升了调水线路的经济效益与运行效率。Aiming at the problem of experiential gate and pumping switching station opening or closing forms in operation lines of inter-basin water transfer projects,the whole line from Xindan Gate sited on the left side of Majia River to Guopanhe Reservoir in Panzhuang Irrigation District along the Yellow River in central Dezhou city,Shandong province was selected as a research area.On the basis of forward recursive method of dynamic programming,two water transfer process models were established with objective functions of optimal economy and the fastest water transfer of water transfer routes.The two water transfer process models were calculated by using Python language to determine gate and pump switching modes,starting instants,and starting time at different operating stages,and economical and fast water transfer optimal dispatching schemes of gate and pump switching combined with flow and water level were obtained.The results show that the initial water level of Goupanhe Reservoir is the main factor affecting the total operating cost and the total water transfer time.The optimal dispatching schemes of gate and pump switching can reduce the operating cost by 20%,sh orten the total water transfer time by 8%,and improve the economic benefits and operating efficiency of the water transfer lines.
