摘要
分析了双馈电机速度调节和功率因数调节的基本原理,从主电路拓扑结构、定向矢量选择、磁链观测器结构和原理、前馈解耦控制等方面对双馈调速系统进行了研究,搭建了定子磁链定向双馈调速系统仿真模型,验证了双馈电机调速的优越性。在基于DSP(TMS320LF2812)的实验平台上,初步完成有速度传感器定子磁场定向矢量控制实验,证明了矢量控制的可行性与优越性。
Analysis was made on the basic principle of the doubly-fed induction motor＇s（DFIM）speed regulation and power factor adjustment.Some research was made on speed regulation system of the DFIM,including the main circuit topology,selection of the oriented vector,flux observer structure and principles,feed forward decoupling control,etc.The simulation model of stator flux oriented doubly-fed induction motor＇s speed regulation system was established to validate its superiority.Stator field-orientation vector control experiment has been done in the test-bed based on the digital signal processor（TMS320LF2812）.It is proved that the vector system is feasible and superior.
