Title (EN) PROTECTION FOR AN HVDC NETWORK
(FR) PROTECTION D'UN RESEAU HVDC
Abstract:
(EN) The invention relates to a method for protecting a network comprising: -electrical lines (120, 130, 230); -three nodes (10, 20, 30) for interconnection with: -a high-voltage interface with controlled switches; -a local network interface; -local networks for each respective node (10, 20, 30), comprising: -an MMC converter (16, 26, 36); -a protective circuit with, in parallel, a first controlled switch (14) and a first limiter (15), a second controlled switch (12) and a second limiter (13). The method comprises the steps of: -keeping said first switches (14) closed and said second switches (12) open; -measuring voltage and current at the high-voltage interfaces; -communicating the direction of the current, to the other end of a high-voltage line; -for each node: -identifying a fault; -checking that the current is lower than the breaking capacity of the high-voltage interface switch and opening this switch.
(FR) L'invention concerne un procédé de protection d'un réseau comprenant : -des lignes électriques (120,130, 230); -trois nœuds d'interconnexion (10, 20, 30) avec: -une interface haute tension avec des interrupteurs commandés; -une interface réseau local; -des réseaux locaux pour chaque nœud respectif (10, 20, 30), comprenant : -un convertisseur MMC (16,26, 36); -un circuit de protection avec en parallèle, un premier interrupteur commandé (14) et un premier limiteur (15), un deuxième interrupteur commandé (12) et un deuxième limiteur (13). Le procédé comprenant les étapes de : -maintenir lesdits premiers interrupteurs (14) fermés et lesdits deuxièmes interrupteurs (12) ouverts; -mesurer tension et courant sur les interfaces haute tension; -communiquer le sens du courant, à l'autre extrémité d'une ligne haute tension; -pour chaque nœud: -identifier un défaut; -vérifier que le courant est inférieur au pouvoir de coupure de l'interrupteur d'interface haute tension et ouvrir cet interrupteur.
