Azeddine Chaiba - Rachid Abdessemed - Mohamed L. Bendaas
In this paper a torque tracking control algorithm for 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 torque tracking control law is synthesized using PI controllers, while the stator side power factor is controlled at unity level. Results obtained in Matlab/Simulink environment are presented illustrating good control system performance.
