Study on the Dynamic Characteristics of Wind Turbine Based on MATLAB

能源危机和环境污染问题日益严重,人们对其越来越重视,在世界范围内,风力发电技术得到了快速的发展。使用有效的方法提高风电机组的运行效率、最大限度地利用风能,已成为风力发电技术研究的主要内容和方向。因此,对风力发电机组进行仿真建模,为保证风电机组有效地运行提供了客观必然条件。变速恒频风力发电系统的仿真和数学模型的建立是目前国内外的研究热点,也是本文主要分析研究的内容。该文介绍了变速恒频双馈风电机组的工作原理,并对风电机组的数学模型进行分析,最后在Matlab/Simulink平台环境中建立风电机组及电网仿真模型并进行仿真。从仿真结果看,变速恒频双馈风电机组具有优越的运行特性和良好的输出特性。

With attachment importance to energy source scarcity and environment pollution,the wind power generation syster^PGS） has developed dramatically all over the world.How to enhance operation effectively and use the wind energy becomes important matter about the technology of the wind turbine generator system （WTGS）.So the simulation of the model of WTGS provides a necessary condition for the operation of WPGS effe- ctively.VSCF（variable speed constant frequency） wind power generation Simulation Modeling is the main direc- tion at home, is the main contents of this paper.This paper introduces the double-fed VSCF wind turbine＇s work- ing principle.Then analyzes the mathematical model of wind turbine, include.Finally,wind turbines and power simulation model was established Matlab/Simulink simulation supporting platform and simulated.It is proved the superior operation characteristic and good output performance of double-fed VSCF wind turbine.
