| 摘 要： | 将三种极对数的无刷双馈电机(BDFM)与一台绕线转子感应电机进行比较研究。用双向变频器对BDFM进行速度控制，做到减小额定值，并可以实现对BDFM的转速和功率因数进行控制。本文说明了选择变频器的额定值和BDFM的极对数的方法。

| Abstract: | Three alternative brushless doubly fed induction machine (BDFM) pump drive confi gurations are investigated as a replacement for a wound rotor induction machine drive. The BDFM with a bi-directional converter to realize precise speed c ontrol requires a power electronic converter of substantially reduced rating. In addition, the BDFM system offers controlled, unity power factor oper ation. This paper explains the design method in regards to conv erter rating and pole-pair selection. |
