Abstract

L'invention concerne un système d'alimentation en énergie destiné à des réseaux isolés, situés en particulier sur des plateformes de forage pétrolier ou des navires. Ce système d'alimentation en énergie comprend au moins un générateur (3) et au moins deux systèmes à courant triphasé (1a, 1b). L'invention se caractérise en ce que le générateur (3) comprend au moins deux systèmes d'enroulement triphasés de sorte que les deux systèmes à courant triphasé (1a, 1b) déphasés, dans lesquels les systèmes d'enroulement du générateur (3) sont disposés dans l'espace conformément au déphasage électrique des systèmes à courant triphasé (1a, 1b), peuvent être alimentés sans ou sensiblement sans utilisation de transformateurs convertisseurs. Les deux systèmes à courant triphasé (1a, 1b) forment le système primaire (1) et alimentent un système à courant triphasé secondaire (2) au moyen d'un dispositif transformateur (4). De par son poids et son encombrement réduits, le système selon l'invention présente un intérêt tout particulier pour les systèmes isolés.
