摘要:

基于无刷双馈电机的功率绕组电压定向的统一矢量模型的研究,提出了一种矢量控制策略,该控制策略可以对电机转速和无功功率实现解耦控制,同时避免了定子磁链的计算。通过变速调频实验研究,证明了所提出的控制方法具有良好的控制性能。

Abstract:

A vector control scheme was proposed for the Brushless Doubly-Fed Machine (BDFM) based on the PW (Power Windings) voltage-oriented generalized vector model. The control scheme could realize the decoupling control of speed and reactive power, and avoided the calculation of the stator flux-linage. An experimental platform had been built to validate the performance of the control strategies, and experimental results show that the proposed controller had good performance.

Key words: vector control, stator-voltage-oriented frame, brushless doubly-fed machine (BDFM), generalized vector model, frequency conversion velocity modulation experiment system, power windings (PW)
