摘要：Energy is one of the most prominent factors in shaping the civilization of today. Under consideratio n for non- conventional energy source wind energy has turned out to be a leading source of energy. In recent years there has been a significant global commitment to develop a clean and economical alternative sustainable power source especially from wind. In this field of development wound rotor induction generator has seen considerable success. One scheme of wound rotor induction generator is realised when a converter ca scade is used between the slip rings terminals and the utility grid to control the rotor power. This configuration is called D oubly Fed Induction Generator (DFIG). In this paper analyses the voltage sag in a grid connected to a DFIG. The paper implements a control technique to mitigate the voltage sag generated due to a fault. Finally the pap er concludes with an inference of the voltage profile generated by a DFIG and a vivid study of various parameters at varied conditions
