ABSTRACT
Nowadays due to increasing demand and increased gap between supply and demand, distributed generation plays an important role in bridging that gap.
Due to the rapid development of distributed generation technology is gradually reshaping the conventional power system.
wind power is among the most actively developing distributed generation.
This project will develop the issues related to reactive power consumption by induction generators during power evacuation
INTRODUCTION
Majority of the wind power based DG techtnologies employ wind turbine induction generators instead of synchronous generators.
Wind turbine induction generator (WTIG) can be viewed as a consumer of reactive power.
With the variation in the wind speed, the reactive power drawn/supplied by the WTIGs from the distribution network varies.

There are two types of utility-scale wind turbines, fixed and variable speed. Fixed speed wind turbine is used here.
Islanding is a phenomenon which generally occurs in a network with wind generation.
Island is a condition where a portion of a grid is energized solely by distributed generators while that portion of grid is electrically separated from the rest of the power system
