Procede d'amelioration d'une installation de transmission d'energie electrique et installation associee

A method of upgrading a plant for transmitting electric power and such a plant

Abstract

A plant for transmitting electric power through HVDC comprises two converter stations interconnected by a monopolar direct voltage network (7) and each having an alternating voltage side for feeding electric power from one of said alternating voltage sides to the other. Each station has a line commutated converter (3, 4). The plant is upgraded by making the direct voltage network bipolar, providing each station with a Voltage Source Converter (11, 12) and providing two switches (17-20) for both line commutated converters or both Voltage Source Converters and means for controlling said four switches.
L'invention concerne une installation de transmission d'énergie électrique en CCHT qui comprend deux postes de conversion interconnectés par un réseau en tension continue monopolaire (7) et ayant chacun un côté tension alternative pour alimenter l'énergie électrique d'un des côtés tension alternative à l'autre. Chaque poste est équipé d'un convertisseur à commutation de ligne (3, 4). On améliore l'installation en rendant bipolaire le réseau en tension continue, et en fournissant à chaque poste un convertisseur de source de tension (11, 12) ainsi que deux commutateurs (17-20) aux deux convertisseurs à commutation de ligne ou aux deux convertisseurs de source de tension ainsi que des moyens de régulation desdits quatre commutateurs.
