Public ISBD Titre : Etude d’une chaine de conversion de l’energie Eolienne Type de document : texte imprimé Auteurs : Naim Cherfia, Auteur ; Djallel Kerdoun, Directeur de thèse Editeur : جامعة الإخوة منتوري قسنطينة Année de publication : 2018 Importance : 144 f.

Index. décimale : 622 Electro-Technique Résumé : This work presents the study of the conversion of energy produced by Doubly Fed Induction generator connected directly to the network by its stator and driven by its rotor by two bidirectional converters. First, we presented the state of the art on wind energy and the conversion systems used (types of generators, most used configurations, etc ...). Then we exposed the mathematical models of each element of the wind turbine (the wind turbine and its command MPPT + the generator). Then we evaluated and examined two methods of vector control in power of the MADA in generator mode, the first to know: the direct command and the indirect command with the help of the correctors PI. According to the simulation results obtained, the indirect vector control with two cascade loops shows better performances for an invariant system. Finally, for nonlinear systems where with non-constant parameters, we applied the sliding mode control to control the active and reactive power with the use of an inverter controlled by the SVM technique to improve the electrical energy quality. to inject this energy into the electricity grid or we note that the simulation results show the reliability and robustness of this command which is given a good track of active stator power its reference with a negligible error.
