Les Microcentrales Hydrolectriques: Etude Du Systme De Conversion Electromcanique D'Une Microcentrale Hydrolectrique Vite,Used
Delivery time: 8-12 business days (International)
La petite hydraulique possde un fort potentiel de dveloppement, les applications vises tant l'alimentation de sites isols, non lectrifis, ainsi que la fourniture d'appoint au rseau interconnect, notamment par association avec d'autre sources renouvelable. Le but de ce travail concerne l'tude thorique et exprimentale de la structure d'une microcentrale hydrolectrique vitesse variable. Le systme est constitue par une machine asynchrone double alimentation, excite, au rotor par une machine synchrone aimants permanents; ces deux machine tant montes sur le mme arbre. Deux convertisseurs MLI, rversibles, ralisent la connexion lectrique entre les deux machines. Cette tude concerne les aspects lis la commande des machines lectriques, le fonctionnement de la microcentrale en lotage et en dbit sur un rseau puissant et l'association d'autres sources dcentraliss de production. L'association avec une centrale olienne vitesse fixe a t tudie. En plus, on a ajut un dispositif de stockage supercondensateurs ayant le rle d'augmentation de la capacit de pntration dans le rseaux lots ou puissantes.
