Optimal Dispatching Schemes of Gate and Pump Switching in Water Transfer Project Based on Dynamic Programming Method
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％,shorten the total water transfer time by 8％,and improve the economic benefits and operating efficiency of the water transfer lines.
