Enhanced Fault Diagnosis of DFIG Converter Systems [PDF]
2019 54th International Universities Power Engineering Conference (UPEC), 2019 The converter is a crucial part of the doubly fed induction generator (DFIG) wind energy conversion system (WECS). Breakdown of the converter will lead to huge economic loss; this is relating to the downtime of the converter that will shut down the whole turbine-generator system and curtail the energy production.

Improved Fractional-order Damping Method for Voltage-controlled DFIG System Under Weak Grid
Journal of Modern Power Systems and Clean Energy, 2022 When a doubly-fed induction generator (DFIG) is connected to a weak grid, the coupling between the grid and the DFIG itself will increase, which will cause stability problems. It is difficult to maintain the tracking accuracy and ro-bustness of the phase-
