介绍了一种双馈风力发电机在电网电压不平衡条件下转子侧和网侧变流器的控制方法。特别地，电网侧变换器的控制方案适于在转子侧变换器控制DFIG转矩脉动时辅助控制总功率振荡。在Matlab/Simulink中实现了DFIG模型，仿真结果表明，由于施加的电压不平衡而产生的功率和转矩振荡减少，并且高不平衡电流减少。
The paper describes a method to control the rotor-side and grid side converters in a DFIG when subjected to the effects of network voltage unbalance conditions. In particular the control scheme of the grid side converter is adapted to assist in the control of the total power oscillations when the rotor side converter is controlling the DFIG torque pulsations. A DFIG model is implemented in Matlab/Simulink and simulations show the reduction in power and torque oscillations and a reduction in the high unbalanced currents generated as a result of the applied voltage unbalance.
