用于扩展风速范围的小型并网风力发电系统的电路配置与控制

In this paper, a grid-tie small-scale wind generation system is proposed with innovations in both of the topology and the controller. A novel high step-up zero-current turning-on soft-switching rectifier and a storage branch are employed to improve the low-wind-speed (LWS) and high-wind-speed (HWS) performances. The optimized LWS operation is guaranteed by the rectifier, the battery pack, and film...
