摘　　要：根据风力机的特性 ,探讨了追踪、捕获最大风能的方法 ;在分析双馈型异步发电机数学模型和磁场定向矢量变换控制的基础上 ,提出了变速恒频风力发电机的有功、无功功率解耦控制策略 ,详细的仿真研究验证了控制策略的正确性和可行性。Based on the analysis of wind turbine characteristics, the idea of tracing and capturing maximal wind energy is investigated. By analyzing the mathematical model of a doubly fed induction generator (DIFG) and the field oriented vector transformation control scheme, the control strategy of a variable speed constant frequency (VSCF) wind energy generator which can realizes the independent regulation of the active power and reactive power of DIFG is put forward. Detailed simulation study verifies the correctness and feasibility of the proposed control strategy.
