摘　　要：在分析了风力机功率特性和DFIG运行特性的基础上,通过对双馈机转速控制进行最大风能追踪具体过程的深入研究,提出了一种基于最大风能追踪的双馈电机有功、无功功率的解耦控制方法。建立了基于发电机定子磁链定向矢量控制的双馈风力发电系统最大风能追踪系统模型,并利用PSCAD/EMTDC对其进行仿真,结果验证了控制策略的正确性。On the basis of the analyzing output power of wind turbine and the operation characteristics of DFIC, a deeoupling control method of the active and reactive power of DFIG based on the maximum wind energy tracking is proposed, by means ofanalyzlng the specific process of controlling the rotor speed of DFIG to track maximum wind energy. Then, a control system model for tracking the maximum wind energy based on a stator flux-oriented vector control is built, the simulation ofwhieh is tan＇led out with PSCAD/EMTDC. The results have verified the feasibility of the control strategy.
