Flexible Alternating Current Transmission Systems News

ABB, the leading power and automation technology group, has won an order worth about $35 million from Hydro-Québec to upgrade the 350 megawatt (MW) Madawaska high-voltage direct current (HVDC) transmission link, that connects the grids of New Brunswick and Hydro Québec in southeast Canada. The order was booked in the second quarter of 2014. The project scope includes installation of ABB’s MACH control and protection system and the upgrade of the valves and valve cooling system. The back-to-back converter station has been in operation for more than 25 years and the modernization is expected to significantly improve grid reliability and help reduce maintenance needs. The new station is scheduled to go into full operation in 2016.
