摘　　要：变桨距风力机在不同风速下具有不同的运行状态和输入输出关系。文章根据空气动力学理论研究了风力机静动态特性;探讨了不同风速下,变桨距风力机的控制方案及运行状态;根据变桨距风力机不同的运行状态,设计了发电机特性和桨距角控制方案;在matlab/simulink环境下,建立了适应变桨距风力机全状态的模拟系统;在匀速风、阵风、渐进风和阶跃风下,对模拟系统进行了全面的实验验证。结果表明模拟系统的控制方法切换,输出量变化,变量参数的改变均与实际设计期望相符,证明了所建模拟系统能准确实现变桨距风力机的特性,并能全面模拟多运行状态下的变桨距风力机。Wind turbine with variable blade pitch adopts different running-status and different input output relationship at different wind speed. On the basis of theoretical aerodynamics, the static and dynamic characteristics of wind turbine are studied. Control methods of wind turbine with variable blade pitch at different wind speed are explored. According to the different running-status of variable blade pitch wind turbine, generator characteristic and pitch angle control system are designed. In matlab / simulink environment, the simulation system of variable blade pitch wind turbine for total statuses is built, as well as the simulation system experiments are made under the action of wind load which has the characters of uniformity, gust, gradualness and step. During the test, the responses of control method, output and parameter are identical with expectation. Test result confirms that the simulation system can accurately simulate working characteristic and different running-status of variable blade pitch wind turbine.
