Title (EN) DIRECT CURRENT HANDLING IN AN INTERFACE ARRANGEMENT
(FR) GESTION DE COURANT CONTINU DANS UN AGENCEMENT D'INTERFACE
Abstract:
(EN) An interface arrangement for connection between a first Alternating Current (AC) power system (ACS1) and a second power system comprises a first converter (14), converting between alternating current (AC)and direct current (DC),and having an AC side and a DC side, where the DC side is connected to a DC network (DCN),an AC line (L1) connecting the first power system to the AC side of the first converter (14) and at least one current sensor (20) sensing the currents of the AC line (L1). The first converter (14) comprises a set of converter valves and a control unit operative to control the set of converter valves to generate at least one AC waveform on the AC line (L1) and to remove DC current components of the currents (iva1, ivb1, ivc1) being sensed by the at least one current sensor(20) in the AC line.
(FR) L'invention concerne un agencement d'interface pour la connexion entre un premier système d'alimentation en courant alternatif (CA) (ACS1) et un second système d'alimentation comprenant un premier convertisseur (14), convertissant un courant alternatif (CA) et un courant continu (CC), et présentant un côté CA et un côté CC, le côté CC étant connecté à un réseau CC (DCN), une ligne CA (L1) connectant le premier système d'alimentation au côté CA du premier convertisseur (14) et au moins un capteur de courant (20) détectant les courants de la ligne CA (L1). Le premier convertisseur (14) comprend un ensemble de valves de convertisseur et une unité de commande destinée à commander l'ensemble de valves de convertisseur en vue de générer au moins une forme d'onde CA sur la ligne CA (L1) et d'éliminer les composantes de courant continu des courants (iva1, ivb1, ivc1) détectés par ledit capteur de courant (20) dans la ligne CA.
