Upgrade of world's
first multi-terminal link boosts supply of renewable energy and grid stability
for coming decades
ABB has completed the upgrade and
refurbishment of the three high voltage direct current (HVDC) converter
stations on the power transmission link between Québec, Canada and New England,
US for the leading Canadian and US utilities Hydro-Québec and National Grid. The
1,500-km link will enable populous centers like Boston to benefit from
alternative sources of electricity.
interconnection was the world's first multi-terminal link and since entering
service in the early 1990s, it has provided the highly populated areas of
Montreal and Boston with clean hydropower. With a total capacity of 2,000 megawatts, the link
can provide enough hydro-electricity for 3.8 million people, based on average
US household consumption.
critical part of the project has been ensuring minimal power interference and
enabling commercial operation to be restored swiftly. As part of this latest
upgrade, ABB has replaced the link's hardware and software with its
state-of-the-art MACH control and protection system. This ensures a continued,
reliable and highly controllable power supply and enables advanced smart-grid
studies for further grid optimization in a timely manner.
As a key
element of the upgrade, ABB has installed its MACH control and protection
system, which acts like the brain of the HVDC link. It offers a high degree of
integration capability to handle control and protection functions, designed to
run around the clock for decades. It also incorporates advanced fault
registration and remote control functions. There are over 1,100 such systems in
operation throughout the world.
pioneered HVDC technology and continue to lead the way through innovation, as
with the latest control system being installed for this project" said Patrick Fragman, Managing
Director of ABB's Grid systems business, a part of the company's Power Grids
division. "The upgrade of the world's first multi-terminal link reinforces
ABB's commitment to supporting customers through the lifecycle, and reiterates
our focus on the service business, as part of our Next Level Strategy."
ABB has been
awarded over 110 HVDC projects since it pioneered the technology more than 60
years ago, representing a total installed capacity of more than 120,000
megawatts and accounting for about half the global installed base. ABB further
developed HVDC in the 1990s by introducing a voltage sourced converter (VSC)
solution named HVDC Light® and leads the way in this technology as well, having
delivered 18 out of 24 VSC HVDC projects commissioned in the world.
