This book presents a modified model reference adaptive system (MRAS) observer for sensorless vector control of a wind driven doubly fed induction generator (DFIG). A mathematical model of the DFIG as influenced by core loss and main flux saturation is developed. The authors describe and evaluate grid synchronization enhancement of a wind driven DFIG using adaptive sliding mode control (SMC). Besides, grid synchronization of a wind driven DFIG under unbalanced grid voltage is also fully covered in this book.

Presents ?control system behaviors of grid side converter (GSC) and rotor side converter (RSC) based on stator flux oriented (SFO) and stator voltage oriented (SVO) controllers, respectively Reviews the application of multi-level converters in wind turbine-generator sytems Proposes a robust control scheme based on adaptive sliding mode for grid synchronization of DFIG in wind generation system Includes supplementary material: sn.pub/extras
