The Trans Bay Cable is a high-voltage dire … The Trans Bay Cable is a high-voltage direct current (HVDC) underwater transmission cable interconnection between San Francisco, California and Pittsburg, California. The 53 mi (85 km) cable under San Francisco Bay and through the Carquinez Strait can transmit 400 megawatts of power at a DC voltage of ±200 kV, enough to provide 40% of San Francisco's peak power needs. The line connects PG&E's Potrero Substation (formerly the switchyard for Potrero Generating Station) to its 230 kV transmission line in Pittsburg. The system was completed in November 2010. The Trans Bay Cable project was the first HVDC system to use the Modular Multi-Level Converter (MMC) system.odular Multi-Level Converter (MMC) system.
, Trans Bay Cable est une ligne HVDC par câb … Trans Bay Cable est une ligne HVDC par câbles sous-marins reliant San Francisco à Pittsburg. La liaison tire son nom de la baie de San Francisco qu'elle traverse. Elle passe également par le Carquinez Strait. Elle a une longueur d'environ 86 km, une tension de ±200 kV et une capacité de 400 MW, soit 40 % de la demande de pointe de la ville. Du point de vue technologique c'est la première ligne HVDC à utiliser la technologie VSC multi-niveaux, c'est-à-dire source de tension avec peu d'harmoniques. La connexion possédée par SteelRiver Transmission Company, relie le poste électrique de Potrero à celui de Pittsburg, tous deux gérés par PG&E. Son coût est d'environ 505 millions de dollars. Elle a été mise en service en novembre 2010.le a été mise en service en novembre 2010.
