Abstract Improving the electricity production and enhancing the overall and the quality of the electrical grid are obligatory to reach nowadays clients requirements regarding the quality of energy. Thus, the integration of green power such us solar, Wind Power Systems (WPS) and biomass has changed the energy world face, and contributed to satisfy the international needs of energy. The renewable energies are strategic objectives to lead this energetic revolution. In this work, we are interested in the Doubly Fed Induction Generator (DFIG), which is the most used machine in the case of wind power systems. This machine has many advantages such us efforts control over the WPS shaft and the other mechanical parts, less noise and the control of the active and the reactive powers. It uses a back-to-back inverter between the rotor and the grid. The used inverter design can be optimized to reduce the power electronics components losses and then insert it into the grid through transformer. The power control is related to both the DFIG and the way its inverter is controlled. In this paper, we will proceed the structural integrity analysis of a WPS. Indeed, we proceeded a modeling of the DFIG in the rotating (d-q) frame. Then, we applied the vector control of the DFIG, called field oriented control, by approximating the machine model as naturally decoupled current-field machine according to the Park transformation. All the results have been confirmed by simulation in the Matlab\simulink framework.
