摘　　要：论述在分析级联式无刷双馈电机原理的基础上,根据d-q轴数学模型,通过转子和功率绕组、控制绕组之间的坐标变换,得到同步数学模型,并在此基础上推导出无刷双馈电机数学模型。根据次模型进行仿真,仿真结果表明:并网过程中,通过改变励磁电流的大小可调节功率侧输出电压的幅值,从而可实现变速恒频。In order to make growth of the service life and improve its reliability in double-feed machine,synchronized mathematical model through the winding coordinate transformation among rotor,power and control coordinates in d-q axis model,and brushless double-feed motor mathematical model is given.The simulation results show that ：in the course of the grid,by changing the excitation current size,power side output voltage amplitude is adjusted,and VSCF is achieved.
