| 中文摘要 |
| 无刷双馈风力发电机中的3套绕组电流(功率绕组、控制绕组和转子绕组)产生的磁场在电机空间相互作用,绕组间复杂的耦合关系导致无刷双馈电机模型具有高维数特征. 为了更有效地对无刷双馈风力发电机进行运行分析与功率控制, 充分利用无刷双馈风力发电机的多时间尺度特征, 实现模型降阶是必要的. 研究了无刷双馈风力发电机的多时间尺度特征, 建立了无刷双馈风力发电机的三时间尺度奇异摄动模型, 为无刷双馈风力发电机的模型降阶奠定了基础. |
| 英文摘要 |
| Since the magnetic fields caused by currents of the three windings (power winding, control winding and rotor winding) of brushless doubly-fed wind generator (BDFWG) interact one another in electric machine space, and the complex coupling relation among the windings exists, consequently, BDFWG model has the nature of high dimensions. It is important to reduce the order by making use of the characteristic of multi-time scale of BDFWG, either for operation analysis or for power regulation of BDFWG. In this paper, the nature of multi-time scale of BDFWG is discussed and the relevant singular perturbed model with three-time scale is built. The model of BDFWG derived in the paper lays the theoretical foundation for order reduction of BDFWG. |
