【摘要】 针对微型水电站中水轮机组频率波动较大且运行不稳的问题,本文采用了一种单纯形法与遗传算法相结合的混合遗传算法对其PI调速器进行了优化设计,根据工程实际完成了调速系统的数学建模,并应用MATLAB6.5软件对遗传算法和传统PI算法的控制效果进行了仿真分析和比较,实践证明应用该方法能够有效的解决此问题。更多还原

【Abstract】 Aiming at the great fluctuating of hydraulic turbine unit’s frequency and the problem of unsteady operation, by using the blending genetic algorithm which is a combination of simplex method and genetic algorithm, this thesis carried on an optimizing design to its PI velometer, and established the mathematics model of speed regulating system based on project practice.This thesis also carried on simulation analysis and comparation to the control effect of the genetic algorithm and the traditional PI algorithm by using MATLAB 6.5 software. The practice proved that this method is able to solve this problem effectively.更多还原
