Abstract: The present research work deals with the control of grid frequency by controlling the operation of doubly fed induction generator and also control regulation of active power of demand and Supplied by grid with help of doubly fed induction generator. The evolution of technology Related to wind systems industry leaded to the development of a generation of variable speedWind turbines that present many advantages compared to the fixed speed wind turbines. These Wind energy conversion systems are connected to the grid through Voltage Source Converters (VSC) to make variable speed operation possible. The studied system here is a variable speed Wind generation system based on Doubly Fed Induction Generator (DFIG). The rotor side Converter (RSC) usually provides active and reactive power control of the machine while the Grid-side converter (GSC) keeps the voltage of the DC-link constant. The additional freedom of Reactive power generation by the GSC is usually not used due to the fact that it is more preferable to do so using the RSC. This paper deals with the introduction of Doubly fed induction Generator, AC/DC/AC converter control and finally the MATLAB simulation and build the Model in D-space platform, for isolated Induction generator as well as for grid connected Doubly Fed Induction Generator and corresponding results and wave forms are displayed.
