The doubly-fed induction generator (DFIG) is widely used in variable speed wind energy conversion systems(WECS). This paper presents a review on various topologies, configuration, power converters and control schemes usedwith the operation of the DFIG. The main contribution of this work lies in thecontrol of GSC for supplying harmonics in addition toits slip power transfer. The rotor-side converter (RSC)is used for attaining maximum power extraction and tosupply required reactive power to DFIG. Wind energyconversion system (WECS) works as a staticcompensator (STATCOM) for supplying harmonicseven when the wind turbine is in shutdown condition.Control algorithms of both GSC and RSC arepresented in detail. Implemented project DFIG-basedWECS is simulated using MATLAB/Simulink. Aprototype of the proposed DFIG based WECS isdeveloped using a digital signal processor (DSP). Thewind energy is the preferred for all renewable energysources.

KEYWORDS-Variable speed DFIG, MPPT, windenergy, power quality, active filtering, GSC
