Abstract

La présente invention concerne un système couplé directement au réseau de transmission ou au réseau de distribution, avec lequel une machine asynchrone doublement alimentée et à vitesse de rotation variable est combinée avec un volant d'inertie. En plus de la fonction en tant que déphaseur régulant la tension, de l'énergie peut être simultanément accumulée ou prélevée dans le volant d'inertie par la modification de la vitesse de rotation. Les propriétés proposées concernent une combinaison de contrôle de la fréquence, de stabilisation de la tension, d'accumulation d'énergie et de capacité en court-circuit. Dans un mode de réalisation particulier, la vitesse de rotation du volant d'inertie est surélevée par rapport à la vitesse de rotation du rotor au moyen d'engrenages; de manière préférée, la capacité du volant d'inertie à accumuler de l'énergie augmentant de manière surproportionnelle à la vitesse de rotation.
