Abstract

L'invention concerne un mode de gestion de l'énergie pour assurer la commande d'ensembles modulaires pour des opérations de traitement et/ou de transport, au niveau de machines et d'installation. L'invention vise à mettre au point un concept de commande permettant, pour des applications à masses d'inertie élevées en mode de fonctionnement réversible, d'atteindre des rendements élevés de l'ensemble du système. A cet effet, il faut éviter une conversion de l'énergie de freinage en énergie thermique, atteindre une tension de circuit intermédiaire élevée pour une utilisation maximale optimale des moteurs (courbe caractéristique de tension) et ne solliciter le réseau qu'avec la puissance active réellement requise. A cet effet, la tension de circuit intermédiaire (UDC) est générée par traitement régulé du circuit intermédiaire et est traitée de sorte que la tension de circuit intermédiaire (UDC) ne passe pas en dessous d'une valeur (UDCmin) pouvant être définie au préalable. L'invention concerne dans ce contexte un dispositif qui complète le réseau en énergie lorsque de l'énergie est prélevée dans le circuit intermédiaire, de sorte à maintenir la tension de circuit intermédiaire (UDC) à une valeur (UDCmin) constante et à interrompre la capacité d'alimentation de retour du réseau, en cas de tension de circuit intermédiaire UDCmin < UDC < UDCmax.
