摘要
针对农村微型水电站水轮机组转速波动较大且运行不稳的问题,采用了一种单纯形法与自适应遗传算法相结合的混合遗传算法,对调速器的比例积分系数进行了优化设计;根据工程实际,完成了对水轮机调速系统的数学建模;应用MATLAB6.5软件,对该改进算法和传统比例积分算法的控制效果进行了仿真分析和比较。实践证明,应用该法能够有效地解决工程中的实际问题。
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 voltmeter, and established the mathematics model of speed regulating system based on project practice. This thesis also carried on simulation analysis and compared 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.
