摘　　要：给出一种基于实验测量确定无刷双馈电机等效电路中各参数的方法。根据不同运行状态下的不同等效电路,列写回路电压方程,通过推导,得到等效电路中参数的解。以一台15 k W类鼠笼转子无刷双馈电机样机为例,得到无刷双馈电机折算到功率绕组侧等效电路中的参数值。通过与仿真得到的T-n曲线以及实验得到的稳定运行区的T-n曲线段进行对比,验证了该方法的正确性。A method to determine the parameters of the brushless doubly fed machine equivalent circuit based on the experimental measurement was presented.According to the different equivalent circuit under different operating conditions,the loop voltage equation is written.Through the derivation,the solution of the parameters in the equivalent circuit was obtained.Taking a 15 kW,squirrel cage rotor brushless doubly fed machine prototype as an example,the parameter values of the brushless doubly fed machine converted to the equivalent circuit of the power winding side were obtained.The correctness of the method is verified by comparing the T-n curve obtained by simulation and the T-n curve segment of the stable running area obtained experimentally.
