摘　　要：对比了不同的定向矢量控制方式的优缺点 ,采用定子磁链定向的矢量控制方式来控制双馈电机 .双馈电机的控制主回路采用交 /直 /交的形式 .电机的转速在一定范围内从亚同步到超同步速任意可调 .无功功率可调 ,可以为正亦可为负 .根据设计 ,进行了计算机仿真 。The various control strategies for different space vector oriented were compared for the doubly fed machine. The strategy for stator flux oriented vector control was introduced to control the doubly fed machine. The main circuit topology was AC/DC/AC. The rotation speed of machine was adjustable from sub synchronous speed to super synchronous speed in corresponding scope. The reactive power was adjustable. It could be adjusted to positive or negative. According to the design, simulation for Matlab was carried out. It was shown that this control strategy and its topology structure were valid.
