摘　　要：变速恒频双馈风电机组是目前风电机组发展和应用的主流;风电机组控制技术是大规模利用风能的关键。基于变速恒频双馈风力发电机组的工作原理,探讨了目前出现的各种空载并网控制策略和励磁控制方式,重点对矢量控制策略进行了全面的分析。结论总结了当前的研究热点,展望了未来的发展趋势。Variable speed constant frequency doubly fed induction generator （VSCF-DFIG） is the main direction in development and appliance of wind turbine generator. The control technology plays significant role in large-scale wind power usage. Based on the analysis of the operating characteristics of VSCF doubly-fed induc- tion generator, no-load grid-connection techniques and the excitation control strategies, especially the vector control methods, for the DFIG were generalized and analyzed by comparison. Finally,it summarizes the current research hotspots and forecasts the tendency in future.
