摘要：针对风力发电系统中恒速恒频控制低风能利用率的问题，对双馈异步发电机构成的变速恒频风力发电系统，采用在定子磁链定向矢量控制基础上的参数自整定模糊PI控制方法，实现了发电机转子励磁电流在风机变速时的快速跟随，使发电机网侧输出频率保持恒定。仿真结果表明，系统具有良好的动态性能。

Abstract: Aiming at the problem of low utilization of wind energy in the constant speed constant frequency system, the parameter self-tuning fuzzy-PI controller based on stator flux oriented vector control was adopted on the variable speed constant frequency wind power generator system composed by double-fed induction generator(DFIG),which realized the rapid tracking of rotor currents when the rotor speed was changed and kept the output frequency constant. The research results show that the system has good dynamic performance.
Key words: wind power generation; double-fed; vector control; variable speed constant frequency; fuzzy-IP
