Abstract:Aimed at the minimal energy consumption, pump unit commitment and adjusting-speed selected as variables, and pumping flow and speed-adjusting range as constraint condition,the optimal mathematical model for mixed pumping stations was established. Used the method of chaos and Matlab, the optimization program was given.The method of penalty function and scale transformation were used in equality constraints and inequality constraints, respectively. Operation date of a pumping stations was also studied, showing that 3.67% energy could be saved comparing with its actual energy consumed in the same day. The new method is simple and easy to implement, with high accuracy and reliability,so it is an effective way for solving the optimization problem in mixed pumping station.
