【Abstract】 The optimal scheduling problem of city water supplying pumping station is discussed in this paper. Based on fitting the basic performance curve of pump accurately, the mathematic model of the minimum shaft power optimal scheduling of water supplying pumping station is established, because the constraint conditions are mixed with the characteristics of discrete and continuous variables, this paper uses the method of genetic algorithm. Through the simulation experiment to get the optimized combination and speed ratio of pump, ensure the constant speed pumps and timing pumps running in high efficient area, the results show that the algorithm is reasonable and effective.更多还原
