摘　　要：通过对双馈电机精确数学模型的研究,提出了基于传统矢量控制策略的改进方案,建立了考虑电网电压波动下定子磁链定向的质量控制系统模型并进行了仿真。仿真结果表明该方案可以提高双馈发电机在电网故障下不间断运行的能力。Based on the precise model of doubly - fed induction generator （ DFIG）, the improved control scheme for the vector control was proposed, and the simulation model that considering the network fluctuation was also established. The validity of the proposed scheme to improve ride - through ability of the DFIG was proved by the result of simulation.
