摘　　要：为了最大限度地利用风能,风力发电系统应采用变速恒频控制策略。分析了鼠笼异步发电系统、双馈发电系统、无刷双馈发电等变速恒频风力发电系统的原理、性能及特点,通过对比各种风力发电机和各种控制方法的优缺点,对未来风力发电机和风力发电控制技术的发展趋势做了展望:风力发电机大型化;采用变桨距和变速恒频技术;风力发电机采用直接驱动;采用智能化控制等。Wind power generation system should adopt the variable speed constant frequency （VSCF） control strategy in order to maximize the use of wind energy. This paper respectively analyzes the principle, performance and characteristics of the cage asynchronous power generation systems, doubly-fed power generation systems and power generation brushless doubly-fed VSCF wind power system. By comparing the advantages and disadvantages, this paper looks forward the development trends of the wind generator and wind power generation control techniques, such as large-size wind turbine, using variable pitch and variable speed constant frequency （VSCF） technology, wind turbine direct drive, and adoption of intelligent control, etc.
