    Abstract: In this study, a control of totque and unity stator side power factor of the Doubly-Fed Induction Generator (DFIG) is proposed. First, a mathematical model of the doubly-fed induction generator written in an appropriate d-q reference frame is established to investigate simulations. In order to control the rotor currents of DFIG, a control law is synthesized using PI controllers; under conditions of the stator side power factor is controlled at unity level. Results obtained in Matlab/Simulink environment, are presented illustrating a good control system performance.
