Wind Energy Conversion Systems Using Doubly Fed Induction Generator

Abstract

Doubly-fed induction generator (DFIG) are widely used for variable speed wind energy conversion systems(WECS). This paper presents a detailed analysis on various topologies, configuration, power converters and control schemes usedwith the operation of the DFIG. The main involvement of this work fabrication 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. of both GSC and RSC control algorithms are presented in detail. DFIG-basedWECS is implemented 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.
