It is very important to establish an accurate model of permanent magnet synchronous wind power generator for analyzing and controlling the security and stability of power system,but the generator parameters are difficult to determine accurately.As the fact that current fundamental component and harmonic component of three-phase short-circuit current occurred in electric power system are determined by generator parameters,a parameter identification method of permanent magnet synchronous wind power generator based on improved SVD-Prony algorithm is proposed.Through the case studies of two types of examples,it is proved that the proposed parameter identification method of permanent magnet synchronous wind power generator is feasible,the identification model is effective and the parameters are accurate.%准确建立永磁同步风力发电机模型对分析与控制电网安全稳定至关重要,但发电机参数难以准确确定,因此依据永磁同步风力发电机定子侧三相短路电流的基波分量和谐波分量变化规律由发电机参数决定的特征,提出了基于改进SVD-Prony算法的永磁同步风力发电机参数辨识方法.通过对2种类型的算例进行参数辨识,验证了本文提出的永磁同步风力发电机参数辨识方法可行、辨识模型有效、辨识参数准确.
