| 摘 要： | 变速恒频风电机组采用矩阵变换器励磁的双馈感应发电机，利用定子磁链定向的矢量变换控制，将同步d-q坐标系下的双馈电机数学模型简化后得到矢量控制模型，该模型与m-t坐标系下的双馈电机数学模型一起构成有功和无功功率解耦控制的双闭环PI控制方案。实验结果验证了定子磁链定向的矢量控制策略既能保证定子输出频率恒定，又能较好地跟踪风力机的最大功率输出。

| Abstract: | Doubly Fed Induction Generator(DFIG) based on matrix converter excited is applied in Variable-Speed Constant-Frequency(VSCF) wind power unit.The mathematical model of DFIG at d-q coordinate system is simplified by stator flux-oriented vector transform controlling.The dual closed loop PI scheme of decoupling control active and reactive powers of DFIG is established by merging the simplified vector controlling model and the mathematical model of DFIG at m-t coordinate system.The stator flux-oriented vector controlling strategies of keeping stator frequency constant and capturing the maximum wind power are verified by experiment results. |

| Keywords: | matrix converter wind power DFIG stator flux-oriented decoupling |
