摘　　要：基于变速恒频双馈风力发电机组,通过调节发电机转侧子电流的大小调节系统的有功功率和无功功率,实现解耦控制,并在理论推导的过程中建立数学等效模型。最后运用MATLAB/Simulink电力系统建模与仿真平台分析发电机组在无功控制模式下风电系统在稳态和三相短路故障下运行输出特性。Based on the variable speed constant frequency doubly-fed wind power generator set, the decoupling control was realized by adjusting the size of the side son current generator/lctive power and reactive power control system, and the equivalent mathematical model was build up in the process of theoretical derivation. Finally, generator reactive power control mode in the wind system running under the steady state and the three-phase short-circuit fault output characteristic was analyzed by using MATLAB/Sirnulink platform of power system modeling and simulation.
