In a multi-terminal HVDC power transmission network (10) comprising at least three HVDC converter stations (1 to 6) interconnected by at least two transmission lines (12, 14, 16, 18, 20), where at least one of the transmission lines is a long line, an active voltage source device (30) is series connected to one of the transmission lines (20), which maintains the DC voltage of the transmission lines of the network to be within a predefined voltage range by injecting an additional DC voltage in series with the one transmission line (20).
Dans un réseau CC (10) de lignes à haute tension à plusieurs terminaux comprennant au moins trois postes de conversion (1, 2, 3) interconnectés par au moins deux lignes (12, 14, 16, 18, 20) de transmission dont l'une au moins est une ligne longue, un dispositif (30) actif de source de tension monté en série sur une une (20) des lignes de transmission maintient la tension CC des lignes de transmission du réseau dans une plage prédéfinie en injectant une tension CC additionnelle en série avec la ligne de transmission (20).
