Modeling and Simulation of Wound-Rotor Brushless Doubly-Fed Motor

从基本方程出发,通过坐标变换,建立了绕线型BDFM的d-q转子速数学模型,导出了电磁转矩表达式,利用转子速数学模型建立了绕线型无刷双馈电机的Matlab/Simulink动态仿真模型,并利用该仿真模型进行了各种运行方式的仿真,仿真结果验证了绕线型无刷双馈电机模型的正确性和可行性,同时也为对该类电机的进一步研究奠定了一定的理论基础。

Based on the fundamental equation of brushless doubly-fed motor（ BDFM）, the mathematical d-q rotor speed model of wound-rotor BDFM was established by coordinate trans- formation, and the electromagnetic torque expression was derived. The MATLAB/ SIMULINK dynamic simulation model of the motor was established by the mathematical rotor speed model and then the simulations with various operating ways were carried out by the simulation model. The simulation result verifies that model of the wound-rotor BDFM is correct and feasible, thus it provides some theoretical basis for further research of this type of motors.
