Fixed speed wind turbine consisting of induction generator is the simplest wind energy conversion system because of its robustness, reliability and simplicity. Due to the development of power electronics different configurations of variable speed concept in wind energy schemes are available. But still in India, grid behavior is dominated by fixed speed wind farms consisting of induction generators. In olden days wind power penetration into grid was very low. A grid connection requirement in order to keep acceptable and reliable operation of the power system was not needed because of this low level of wind penetration. There are an important amount of fixed speed generators still in use that have to be upgraded to the new grid code requirements. Wind turbines with induction generator need reactive power support. A simulation based analysis is carried out to investigate the suitability of application of a STATCOM to achieve Indian grid code compliance of 60MW wind farm with fixed speed induction generator. The rating requirement of the capacitor bank for the wind generation application has been investigated. The compatibility of wind farms having fixed speed generators with Indian grid code requirement is evaluated using Matlab/Simulink.
