Title (EN) CONTROLLING A VOLTAGE SOURCE CONVERTER IN A DC SYSTEM
(FR) COMMANDE D'UN CONVERTISSEUR DE SOURCE DE TENSION D'UN SYSTÈME À COURANT CONTINU
Abstract:
(EN) The invention is concerned with a first voltage source converter (14) and converter station (10) comprising such a first voltage source converter (14) as well as to a method and computer program product for controlling the first voltage source converter. The first voltage source converter (14) has a DC side for connection to a DC system (22), has an AC side for connection to an AC system (ACB1) and is interconnected with an AC side of a second voltage source converter (16), which has a DC side connected to the DC system(24). The first voltage source converter (14) comprises a number of converter valve pairs, each being connected to a corresponding AC phase of the AC system (ACB1) and a control unit controlling the converter valves to generate at least one AC waveform and to reduce oscillations between the converters (14, 16).
(FR) L'invention concerne un premier convertisseur de source de tension (14) et une station de conversion (10) comprenant ledit premier convertisseur de source de tension (14) ainsi qu'un procédé et un produit programme d'ordinateur permettant de commander le premier convertisseur de source de tension. Le premier convertisseur de source de tension (14) comporte un côté CC prévu pour une connexion à un système CC (22), comporte un côté CA prévu pour une connexion à un système CA (ACB1) et est interconnecté avec un côté CA d'un second convertisseur de source de tension (16), qui comporte un côté CC connecté au système CC (24). Le premier convertisseur de source de tension (14) comprend un certain nombre de paires de tubes électroniques de convertisseur, chaque paire étant connectée à une phase de CA correspondante du système CA (ACB1) et une unité de commande commandant les tubes électroniques de convertisseur pour générer au moins une forme d'onde de courant alternatif et réduire les oscillations entre les convertisseurs (14, 16).
