As the conventional sources of power generation are reducing every day there is a strong need for a sustainable and clean source of power which could supply the need. Wind energy conversion systems play a very vital role in production of clean and sustainable energy. In this paper, a DFIG based wind energy system employing DFIG as the power generator is modeled. To improve the transient and steady state performance and the power factor of generation, a stator flux oriented vector control scheme is used in this work. The vector control structure employs conventional PI controllers for the decoupled control of the stator side active and reactive power. This paper emphasizes only on the control of the rotor side bidirectional converter. The whole system is modeled and simulated using Matlab/Simulink and the results are analyzed.
