摘要由于没有电刷和集电环,无刷双馈电机运行可靠,维护成本低廉,因而在风电领域具有广阔的应用前景。在现有的无刷双馈电机的各种控制方法中,定子功率绕组和控制绕组磁链的观测都是必须的。当需要其中一个绕组的磁链在另外一个定子绕组静止坐标系的表达式时,两个静止坐标系之间的坐标变换成为必然,但在实际系统中该坐标变换实现起来十分困难。该文提出一种笼型转子无刷双馈电机在任意一个定子绕组静止坐标系观测另外一个定子绕组磁链的方法,该方法简单且不需要坐标变换,因此易于在实际系统中实现。仿真和实验结果表明,该方法观测结果比较准确,可以满足实验系统对于动态性能的需求。所提方法同样适用于绕线型转子无刷双馈电机。

Abstract：The brushless doubly-fed machine (BDFM) has the benefits of low maintenance cost and high reliability due to the lack of a brush gear and slip ring, so it has broad application prospects in the field of wind power generation. In the existing control methods of BDFM, the flux linkage observation of the power winding and the control winding is necessary. However, when the flux linkage of one stator winding needs to be transformed to another stator winding static reference frame, the coordinate transformation is difficult. A new method to observing the flux linkage of one stator winding in another stator winding static reference frame is given. The method is simple and easy to accomplish because it does not require coordinate transformation. The simulation and experiment results show that the method is accurate and can meet the requirements of the experimental system for dynamic performance. The proposed method is also suitable for wound-rotor brushless doubly-fed machine.

Key words： Cage-rotor brushless doubly-fed machine static reference frame coordinate transformation flux linkage observation
