摘　　要：在双馈电机定子磁链定向控制系统中,针对传统稳态下电压前馈补偿存在转子电流d、q分量小幅振荡问题,设计了一种改进的考虑定子磁链微分在内的电压前馈补偿解耦控制方法。仿真结果表明,该方法解耦控制效果良好,改善了定子无功调节对系统稳定性的影响,抑制了磁链和转速的振荡,增大了无功调节范围,对于提高系统的稳定性意义重大。In the doubly-fed induction machine control system with stator flux oriented, aiming at the problem of oscillations occurred in the rotor current＇s d, q components under the traditional voltage feed forward compensation, an im proved decoupling control method was designed, which considered the derivative of the flux in the compensation of voltage feedforward. The results of simulation show that this method achieves better performance of decoupling control, im proves the effect of stator reactive power control on system reliability, restrains the oscillations of the flux and the rotor speed, and extends the range of the reactive power control. So, it has great significances for improving system reliability.
