摘　　要：围绕双馈异步机的等效电路参数,首先根据经典的π型等效电路,推导等效电路中各参数的理论计算方法,并兼顾实际测量中的可行性问题,提出了一种等效电路参数的有限元计算方法,有限元方法可考虑到电机内磁场及磁路的实际工作状态,使得等效电路参数计算更加精准,为后期电机与变流器的匹配提供准确依据。For the equivalent circuit parameters of doubly-fed induction generator,this paper firstly deduces the theoretical calculation method of each parameter according to classicalπ-type equivalent circuit,and proposes a finite-element method of calculating the parameters through combining with the feasibility of practical measurement.The method can take into account the actual working state of magnetic field and magnetic circuit in the motor,which makes the calculation of equivalent circuit parameters more accurate and provides an accurate basis for the matching of the generator with the converter in later stage.
