针对风电机组复杂、非线性的特点，建立了完整的风电机组变桨距模型，并运用Matlab／Simulink强大的功能对其进行仿真研究。根据风电机组的数学模型，在Simulink环境下搭建了系统仿真模块，并在给定风速下对不同P ID参数的变桨距控制系统进行仿真实验。实验结果表明：参数的设置决定了系统性能的好坏，合适的参数选取能使系统获得较好的动态特性。利用Simulink进行仿真实验，能促进学生对风电机组控制系统的理解，提高学生的仿真能力，使学生掌握变桨距控制系统的结构和动态特性。

Matlab/Simulink , which has strong functions , is used in dynamic simulation research for the complex nonlinear variable pitch control system .Based on the mathematical model of wind turbines ,the simulation modules are built in Simulink environment .Under the condition of a given wind speed ,the simulation experiments are carried out for the variable pitch control system with different PID parameters .The experimental results manifest that the parameters determine the performance of the system and the suitable parameter selection can make the system to achieve better dynamic performance . The simulation experiment with Simulink can not only promote students’ understanding of theoretical knowledge;but also improve their ability of simulation so as to grasp the structure and properties of variable pitch control system further .
