随着可持续发展理念的深入，风力发电作为可再生能源得到了快速的发 展。风力发电系统的仿真在风力发电系统分析，发电量分析和电网的能量的 分析中都起到了非常重要的作用。 本文应用 MATLAB 软件，对风速、风轮、传动机构、发电机、与风力发 电相关的电力电子系统建立了数学模型，并进行仿真进方面的研究，得到了 可供分析的仿真结果。介绍了风力发电机组的控制技术，主要是变桨距控制 和发电机变速控制，并利用 MATLAB 软件对变桨距控制系统和低于额定风速 和高于额定风速时的变速风力发电系统进行了仿真。对双馈发电机的解耦控 制进行了仿真。并列举了典型的风力发电系统仿真实例。 (With the wild spread of concept of continuable development ， wind power generation, as a renewable resource, is getting fast development. The simulation of wind power system play a important role in yield of analysis of wind power generation system, the quantity of wind power generation , power generation system. This paper establish wind model, the wind turbine rotor model, drive trains model, induction machine model ， the electric power electron parts of wind power generation model, Then using soft of MATLAB, we realize the simulation. It introduces the control technology of wind turbine, mainly including variable blade pitch and variable speed control of wind turbine. Using Matlab simulate these. And lists an example of practical applying.)
