摘　　要：根据风力机的运行特性以及双馈发电机的数学模型,提出了一种不需要检测风速的最大风能捕捉控制策略,这种控制策略实现了双馈发电机在亚同步速、同步速以及超同步速的有功功率、无功功率的解耦控制,利用Matlab/Simulink软件,建立了定子磁场定向的双馈电机风力发电系统的仿真模型,分析了相关的输出特性,其控制策略的正确性和稳定性得到了验证。According to the characteristics of wind turbines and the model of double-fed induction generation(DFIG),the strategy was put forward which need not detect the wind speed.This control strategy realized the decoupling of the stator active and reactive power regulating of DFIG.The simulation model of doubly fed induction generator(DFIG)wind power generation system with stator field oriented is established by using Matlab/Simulink software.The related output characteristics are analyzed,and the correctness and stability of the control strategy are verified.
