Title (EN) VOLTAGE REGULATION FOR A SUBSEA CONTROL SYSTEM
(FR) RÉGULATION DE TENSION POUR UN SYSTÈME DE CONTRÔLE SOUS-MARIN
Abstract: front page image
(EN)A subsea control system comprises: at least one electrical cable (12, 14) having first and second points spaced apart along the length of the electrical cable or cables; a power supply electrically (6) connected to said first point, and arranged to supply a first alternating voltage to said first point; at least one subsea control device (4), for assisting in the control of a subsea oil and gas production system, said subsea control device being electrically connected to said second point so as to receive at said second point a second alternating voltage as a result of transmission along said cable or cables of said first alternating voltage; and • a voltage regulator (8) for varying the magnitude of said first alternating voltage in dependence on the electrical load applied to said second point.
(FR)L'invention concerne un système de contrôle sous-marin qui comprend: • au moins un câble électrique (12, 14) ayant des premier et second points espacés le long de la longueur du ou des câble(s) électrique(s); • une source de courant électriquement (6) connectée audit premier point, et disposée pour fournir un première tension alternative audit premier point; • au moins un dispositif de contrôle sous-marin (4), pour aider au contrôle d'un système sous-marin de production d'huile et de gaz, ledit dispositif de contrôle sous-marin étant électriquement connecté audit second point de manière à recevoir audit second point une seconde tension alternative en résultat de la transmission le long dudit câble ou desdits câbles de ladite première tension alternative; et • un régulateur de tension (8) pour varier la grandeur de ladite première tension alternative en fonction de la charge électrique appliquée audit second point.
