摘要：Renewable Energy Sources are non-pollutant of environment and environmental friendly when compared to non-renewable sources of energy. Therefore, the integration of renewable energy sources like Wind Energy Conversion System with utility grid is inevitable. Wind Energy is predominant among the non-conventional sources of energy where different conversion technology have been proposed to generate electric power .The Doubly-Fed Induction Generator (DFIG) is popular technique for variable speed wind power generation owing to its flexibility, efficiency, less mechanical stresses, extensive control ability of the generated real and reactive power and cost effective rated power electronics converter.The report x-ray a background study of DFIG in order to introduce the basic features such as variable speed and normal operation of DFIG systems for wind power applications based on three-phase wound rotor induction generator.
