MODELING AND SIMULATION OF DFIG TO GRID CONNECTED WIND POWER GENERATION USING MATLAB

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 induct ion generator. The evolution of technology related to wind systems industry leaded to the development of a generation of variable speed wind turbines that present many advantages compared to t he 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.
