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(Based on the simulation example of the doubly fed fan in the Simulink module in MATLAB, the parameters of the rational fan, distribution network and large power grid are reset on this basis, and the wind speed model with four component superposition method is designed. At the same time, the sudden drop of 110KV power grid voltage, simulation results analysis in different modes of wind farm and dot selection and the simulation of the output characteristics of the wind turbine when the three-phase short circuit fault occurs in the 35KV distribution network)
