As demand of energy is increased very fast in the world, installed capacity of wind turbine increased rapidly. Doubly fed induction generator (DFIG) is popularly used in wind turbine application due to its many advantages. When grid voltage is reduced due to fault, dc chopper connected in parallel to dc-link capacitor is activated. In this paper the effect of dc chopper is highlighted to control the rotor current and dc-link voltage. Simulation results are based on MATLAB-SimPower System.
