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.

Active fault tolerant control for twin wind turbine subject to asymmetric fault [PDF]
2021 International Conference on Control, Automation and Diagnosis (ICCAD), 2021 This paper addresses the problem of control of a twin wind turbine which is subject to an electrical fault affecting only one stator phase of one turbine. An active fault tolerant control is proposed. The performance and robustness of the proposed control, comparing to a passive fault tolerant one developed in the literature, are shown through ...
