The back-to-back converter station has been in operation for more than 30 years and the modernization is expected to significantly improve grid reliability and help reduce maintenance needs. The project, executed for the leading power utility Hydro-Québec, includes the installation of ABB’s latest generation MACH control and protection system and enhancement of the valves and associated cooling system.
“This upgrade will enhance power availability, reduce outages and improve grid reliability in the region.” said Claudio Facchin, President of ABB's Power Grids division. “The success of this project reflects our drive for world class execution and reiterates our focus on service and life extensions, a key element of our Next Level Strategy. ABB’s digital MACH control and protection system acts like the brain of the HVDC link, incorporating advanced fault registration and remote control functions, supporting our efforts to support customers with increased grid automation and digitalization.”
ABB has significant experience in the upgrade of HVDC links around the world, as many such installations are coming of age and this is the 23rd major HVDC modernization project awarded to ABB since 1990.
ABB’s MACH system offers a high degree of integration capability to handle control and protection functions and designed to run around the clock for decades. It is the world's most extensively deployed control solution for HVDC and Flexible Alternating Current Transmission Systems (FACTS) installations, with over 1,100 such systems in operation throughout the world.
