ABB to Upgrade Transmission Control for Vital North American Power Interconnector
ABB, the leading power and automation technology group, has been selected by Hydro-Québec, Canada, for an upgrade of a high-voltage, direct current (HVDC) converter station. The 25-year-old 1000-MW (Megawatts) Châteauguay back-to-back HVDC station will be equipped with ABB’s control and protection system, MACH 2.
ABB has the widest experience of control system upgrades in the HVDC industry. Recent upgrade projects delivered by ABB include the Square Butte and the CU HVDC links in the U.S., the two Skagerrak HVDC links in Scandinavia and the on-going refurbishment of the Apollo converter station of the Cahora Bassa HVDC link in Southern Africa.
Hydro-Québec generates, transmits and distributes electricity, mainly using renewable energy sources. The company provides electricity to customers in Québec, other parts of Canada, as well as to northeastern parts of the U.S. and is one of the world’s largest producers of hydroelectricity.
The new control and protection system in Châteauguay will be commissioned during April and May in 2009, with an outage time of only seven weeks. Since the station comprises two blocks and each block will be renovated separately, the station will maintain at least half of its capacity during the installation period.
