Improved DFIG capability during asymmetrical grid faults [PDF]
IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015 In the wind power application, different asymmetrical types of the grid fault can be categorized after the Y/d transformer, and the positive and negative components of a single-phase fault, phase-to-phase fault, and two-phase fault can be summarized.
