Optimal operating method of gate and pump switching in water transfer project

Abstract The Yellow River diversion project consists of three gates, two pumping stations, and one plain reservoir, with a total river length 17.46 km in the Panzhuang irrigation area, which provides primary water source for Dezhou central city, Shandong Province, China. is subject to constraints sluice diverting time, reservoir combinations stations self-flowing gates. opening closing forms gates pumps are complicated irregular, switching mainly depends on experience staff, makes transfer cost high time long. Based engineering compositions study an optimal mathematical model constructed by dynamic programming method. By combining flow level, objectives minimum operation cost, shortest combination established. A new optimization scheme switch between combined level proposed, reduces 20% 8%, providing efficient mode.
