摘　　要：分析了双馈电机调速的工作特性,借助于定子磁链定向矢量控制方法,提出了一种U-N模型定子磁链观测器,研究了定子磁链定向双馈调速数学模型,建立仿真模型,验证了双馈电机在次同步和超同步下调速的可行性。Characteristics of doubly-fed induction motor speed regulation system is analyzed, by stator flux vector control methods, a kind of U-N model stator flux observer is put forward, and simulation model of stator flux oriented doubly-fed induction motor speed regulation system was established. Set up simulation model, it is proved that vector system with time synchronization and super synchronous speed is feasible.
