摘　　要：和双馈感应电机相比,无刷双馈感应电机大大提高了运行可靠性。近年来无刷双馈感应电机研究的热点集中在优化设计和控制策略上。间接转矩控制策略是一种新的控制方法,与矢量控制方法相比,该方法无需旋转坐标变换,所用的电机参数较少。在无刷双馈感应电机间接转矩控制系统的基础上进一步提出了一种无功功率的控制方法,在功率绕组静止坐标系推导出无功功率与控制绕组磁链之间的关系,从而设计了无功功率的控制器对无功功率进行控制,仿真结果证明所提无功功率控制策略的有效性。Compared to the doubly fed induction machine（ DFIM）,the brushless doubly fed induction machine（ BDFIM） has higher reliability by virtue of the absence of a brush gear. Recent research on structure optimization design and control strategy of BDFIM has made remarkable progress. BDFIM indirect stator- quantities control is a new control strategy,in comparison to vector control strategy,which requires fewer parameters and does not need rotating coordinate transformation. The method that further adds the dynamic control of reactive power for the BDFIM with indirect stator- quantities control scheme was proposed. The relation between reactive power and control winding flux was derived on the basis of BDFIM mathematical model in the power winding static reference frame. As a result,the reactive power regulator was designed for the reactive power control. The simulation results show the feasibility of the proposed reactive power control scheme.
