免疫遗传算法在变频调速泵站中的应用

针对高速线材厂冷却水循环系统中调速泵站能耗高、效率低的问题，对调速水泵的性能进行了研究，建立了基于免疫遗传算法、变频调速技术以能耗为最小目标的优化运行数学模型，对不等式约束条件进行了简化。在求解数学模型的过程中，免疫遗传算法中融入了一种新的处理约束条件的方法。避免了处理约束条件时遇到的困难和遗传算法易早熟、易收敛等缺陷，使得处理约束问题简单化，并提高了收敛速度。最后通过仿真实验验证了此算法对于解决水循环系统中多台变频调速水泵并联优化运行问题的有效性。

Applications of immune genetic algorithm in frequency speed control pumps

Circulating cooling water system of High speed wire factory had the problem that many pumps of regulating speed operate in higher energy consumption and lower efficiency.The paper analyzed the characteristic of variable speed water pump around the problem.The mathematics model was established with the optimization goal of the lowest energy consumption,which was on the basis of immune genetic algorithm and frequency speed control technology,and it simplified inequality constraint condition.A new way of handling constrained optimization is proposed,which was produced through combining immune genetic algorithm.It avoided the difficulty of handling constraint condition and the premature convergence of genetic algorithm,which make handling constraint problem simplify and improves the global search ability of the algorithm.Simulation results show that it is an effective algorithm to solving optimal problem of many pumps of speed-frequency control in water circulating system.
