100-летний опыт создания HVDC

2010

ABB links the Xiangjiaba hydropower plant in southwest China to Shanghai using UHVDC (ultrahigh voltage direct current) at a capacity of ±800 kV (kilovolts) and 7,000 MW (megawatts) of power over a distance of about 2,000 km (kilometers).

2009

One of the world’s most remote offshore wind farms is connected to the German grid by an HVDC Light transmission system. The 200 km long connection reduces CO2 emissions by nearly 1.5 million tons per year and supports wind power development.

2008

NorNed, the longest submarine HVDC cable in the world at 580 km, links the power networks of Norway and the Netherlands with a transmission capacity of 700 MW.

2005

ABB delivers electricity through a DC (direct current) link originating 70 km away on land to a gas platform in the North Sea, helping avoid annual emissions of 230,000 tons of CO2 and 230 tons of NOX.

2002

ABB links the AC (alternating current) networks of South Australia and Victoria with the world’s longest underground transmission, a 177 km HVDC Light cable with a capacity of 220 MW. ABB also linked Conneticut and Long Island with the world’s first extruded HVDC submarine transmission, a 40 km HVDC Light cable with a power rating of 330 MW.

1997

The first HVDC Light test connection between Hällsjön and Grängesberg in central Sweden marked the start of a completely new power transmission technology – underground and underwater, also over long distances.

1984

The Itaipu link brings hydropower to Sao Paulo, the largest city in the Southern hemisphere, via the world’s first 600 kV HVDC transmission.

1970

Thyristor valves were used for the first time in a commercial HVDC transmission project.

1965

In the 1960s, ABB built several HVDC transmissions systems with converters based on mercury-arc valve technology, for example the Konti-Skan link, the first interconnection between Sweden and the western grid in Denmark.
