In studies of the conversion of wind energy to variable speed, this article proposes a simplified method based on electronics to inject the energy produced in the public electricity network. To reduce the effects of harmonies resulting from commutations, an algorithm of control of active and reactive power is used, but the constraint of WECS is the slow speed of the synchronous permanent magnet generator (PMSG). The strategy of vectorial control on decoupling by singular perturbations was chosen for this work. In our study, the control of the speed and current of PMSG are discussed. Results of simulation are given to show the effectiveness and the performance of the system. |
