中文摘要：

随着能源的大量消耗，人们越来越重视可持续发展能源，风力发电由于其可再生性得到了很好的发展．现阶段的风力发电是比较成熟的一种发电形式．在分析了变速恒频双馈发电机组的工作原理的基础上，建立了风电机组的数学模型，利用Matlab软件对基于双馈感应发电机的变速风电机组进行了仿真，得到了风电机组正常运行和电网故障两种条件下的动态输出特性．

英文摘要：

Along with the consumption of energy, more and more attention is paid to the sustain- able development of energy, and wind power, due to its renewable, has obtained the very good de- velopment. At this stage of wind power is a kind of mature power form. Based on the analysis of the principle of variable speed constant frequency doubly-fed generator, on the basis of establishing the mathematical model of wind turbines, in full consideration of the wind speed and two kinds of conditions of power grid failure, the use of Matlab software simulation has carried on the simula- tion of wind turbines and their interconnection model, doubly-fed wind-power generator for the simulation of the dynamic output characteristics of wind turbines.
