| 摘 要： | 变桨距控制技术是风力发电机组提高对风能的利用的有效方法,由于外界环境的随机性和控制变量的多样性,风力发电系统是一个非线性的系统,其数学模型的建立和仿真是一个难点。本文基于Matlab软件平台,采用机理建模法建立了风力发电机组的各个分系统的子模型,组合成整个机组的数学模型,并采用PID控制算法实现风力发电机组在不同风速下对风能利用的最大化,仿真结果验证了系统模型和控制算法的正确性,为风机控制的创新奠定了理论基础。

| Abstract: | Variable-pitch control technology is an effective method to improve utilization of wind energy Uia the wind turbine.Because the randomness of the external environment and the diversity of control variables,wind power generation system is a nonlinear system,so the modeling and simulation of its mathematical model is difficult.Method in this paper is based on MATLAB software platform.It establishes sub-model of the various subsystems of wind turbine by using mechanism modeling method,then combines them into a mathematical model of the entire unit.And the PID control algorithm is used to realize the maximize use of the wind energy by wind turbines under different wind speed simulation.Results validate the correctness of system model and control algorithms and lay a theoretical foundation for the fan control innovation. |
