Applications of Hybrid Genetic Algorithm in Frequency Speed Control Pumping Station

Circulating cooling water system of high speed wire factory was in trouble for pumps working in higher energy consumption and lower efficiency. The paper analyzed the characteristic of speed water pump. Mathematical model was established with the optimized goal of the lowest energy consumption and it simplified inequality constraint conditions. A new hybrid genetic algorithm to handle constrained problems was proposed. It simplified handling constraint condition and the premature convergence of genetic algorithm, which made handling constraint problem easier and improved the global search ability of the algorithm. Simulation results show that it is an effective algorithm to solving optimal problem of frequency speed control pumps in water circulating system.
