摘　　要：文章描述了定子和转子分别由电网和交-直-交电流逆变器馈电的双馈感应电动机。在双馈电动机数学模型的基础上,对其进行稳态仿真。利用仿真结果设计功率因数调控系统,并对转子侧逆变电路进行设计和控制。考虑到电动机及功率器件的特点,在转子侧通过一个双馈变压器实现与逆变电路的耦合。经调试,系统可达设计要求。In the paper,the doublefed induction machine is introduced in which the stator and rotor are supplied respectively by the power net and the ACDCAC inverter. The mathematical model of the doublefed machine is described,and the simulation results of the stable system are obtained. According to the simulation results,the adjusting and controlling system of the power factor is presented and the inverter circuit of the rotor is designed. Considering the characteristics of the motor and power device, a doublefed transformer which can be connected with the inverter circuit in the rotor is designed. The test result shows that the system meets with the design requirement.
