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.

Impedance Reshaping Method of DFIG System Based on Compensating Rotor Current Dynamic to Eliminate PLL Influence [PDF]
IEEE transactions on power electronics, 2023 The phase-locked loop (PLL) used in the doubly-fed induction generator (DFIG) can cause frequency-coupling phenomena, which will give negative-resistance characteristics of the DFIG at a low frequency, resulting in stability issues under weak-grid ...

A Novel DPC Approach for DFIG-Based Variable Speed Wind Power Systems Using DSpace
IEEE Access, 2023 The integration of wind energy systems into the electric grid has become inevitable despite the many problems associated with this integration. Most of these problems are due to variations in wind speed.
