摘　　要：阐述了双馈风力发电机实现变速恒频的工作原理,讨论了双馈电机的运行状态,推导了双馈电机功率传输方式与转差率的关系,指出了变速恒频风力发电系统的优点是拓宽了风速的可利用范围,对提高风电场发电能力具有重要意义。Expounds the working principle of variable speed constant frequency doubly-fed wind power generator in the aspect of variable speed constant frequency. Discusses the running state of doubly-fed motor and the relationship was deduced between power transmission mode of Doubly-fed motor and the slip ratio. Points out the advantages of variable speed constant frequency wind power generation system is that the range of available wind speed is widen, which is of great signi^cance to improve the wind power generation capacity.
