中文说明：
基于MATLAB中的Simulink模块中的双馈风机仿真示例，在此基础上重新设定合理的风机、配网及大电网的参数，设计加入四分量叠加法的风速模型。同时设计了110KV电网电压突然下降，在风电场并网点选择不同模式下的仿真结果分析和35KV配网发生三相短路故障时的风电机组输出特性仿真。
English Description：
Based on the simulation example of doubly fed fan in Simulink module of MATLAB, the reasonable parameters of fan, distribution network and large power grid are reset, and the wind speed model with four component superposition method is designed. At the same time, the simulation results of 110kV power grid voltage sudden drop under different modes of wind farm network selection and the output characteristics simulation of 35kV distribution network with three-phase short circuit fault are designed.
