一种针对双馈感应发电机风能转换系统的高效故障穿越策略

This article proposes an improved fault-ride-through (FRT) system for a wind turbine with a doubly fed induction generator (DFIG) that is based on the proper stator voltage control to address symmetrical as well as unsymmetrical and unbalanced grid voltage sags. This is accomplished by adopting a properly modified topology of the conventional wind energy conversion system (WECS) with DFIG that pro...
