摘　　要：介绍了级联式无刷双馈发电机的结构和发电原理,根据异步电机的电压方程和坐标变换理论,推导出无刷双馈电机的转子机械速dq坐标系下的数学模型,并进行了Matlab建模和仿真。仿真结果验证了该数学模型的正确性,并为级联式无刷双馈变速恒频发电系统的进一步研究提供了理论基础。Cascade Brushless Doubly-Fed Generator （CBDFG） is very suitable for wind power generation due to its brushless character. Based on the voltage equations of asynchronous motors and the transformation theory of reference frame, a rotating reference frame dq model of CBDFG was derived and related simulation with Maflab was achieved. Detailed curves of the simulation demonstrated the validity of this mathmatic model of CBDFG and its excellent quality for Vari- able-Speed Constant-Frequency （VSCF） power generation.
