基于一种新型变极无刷双馈电机的控制系统仿真

Simulation of Control System for A New Type of Pole-Changing Brushless Double-Fed Machine

这种新型的无刷双馈电机转子采用变极原理设计。建立无刷双馈电机的双轴模型,利用该数学模型建立起无刷双馈电机调速系统的仿真模型,进行动态仿真,针对起动过程中产生的过大电流,研究了采用软起动对电机起动过程的影响。

This new type of brushless double-feed machine＇s rotor is designed by pole-changing method. In this paper, the simulation model of speed-adjustable system of BDFM is proposed by the two-axis mode. Then it researches the influence of the soft starting on the starting performance of BDFM in accordance with the overlarge current caused at starting.
