CONTRIBUTION DES CONVERTISSEURS MULTINIVEAUX AU RACCORDEMENT DE LA PRODUCTION D'ORIGINE EOLIENNE SUR UN RESEAU ELECTRIQUE

Abstract : This work deals with the evaluation of the possibilities which offer the multilevel converters for the connection of a wind generation system including a storage system. First of all, modeling and control of the connection are given. Classically, the grid converter is controlled to regulate the intermediate continuous bus. The use of a NPC converter topology requires the balancing of the DC-bus voltage. A solution based on the redundant configurations is proposed. Then, the modeling and the control of a three-phase multilevel inverter are presented by extending the presented concepts, which are established by using the vectorial mathematical tools. The storage unit is used to control the continuous bus and consequently compensate the fluctuations of the wind power. The energy supervision of the association of both sources is presented and the operation range is given. Various possibilities of the connection of both sources are proposed and evaluated. Experimental validations are given. Finally, the use of a converter using four series capacitors in the DC-bus is developed for the multi source system connections. Various possibilities of connection on this continuous bus are investigated. The supervision system of the powers for each case is also given.
