ABB technologies: High Voltage Direct Current Transmission
The ABB Group of
companies operates in around 100 countries and employs about 135,000 people.
This is a multicultural business that believes in the latest thinking and
technology.
ABB’s high
voltage direct current (HVDC) technology has had a revolutionary impact on the
way that electrical energy is delivered to consumers all over the world.
Some of the world’s
biggest cities – New York, Los
Angeles, Sao Paulo, Shanghai – receive huge
volumes of electric power, often transported over thousands of kilometers with
remarkably low losses and minimal environmental impact, thanks to this
innovation.
Since developing
the world’s first commercial HVDC installation in the 1950s, ABB has designed
more than 60 HVDC projects worldwide. They include the world’s longest HVDC
installation (the Xiangjiaba- Shanghai power link currently under construction
in China, which will deliver
6,400 megawatts of electricity over a distance of 2,071 km) and the world’s
longest underwater cable (the 580-km NorNed interconnection between Norway and the Netherlands).
ABB’s HVDC
technology has also made it possible for countries to interconnect their
national power grids and improve their energy security by exchanging and
trading power with their neighbours.
HVDC has
interconnected the national grids of Europe, the regional grids of the United States (with each other and with Canada and Mexico),
and has linked Argentina
with Brazil.
