In this work, the doubly fed induction generator (DFIG) for wind energy conversion system is studied. First, the dq model of the wound rotor induction machine in rotor reference frame and then how it can be implemented in simulink for fast simulations. In order to control the power flowing between the stator of (DFIG) and the grid, a control law is synthesized using PI controllers. Simulation results have demonstrated its excellent performances, with stator flux orientation control (SFOC).
