ABB wins $180 million order for
Norway-Denmark power transmission link
Feb 26, 2011 - abb.com
the leading power and automation technology group,
has won an order worth about $180 million from utilities
Statnett of Norway and Energinet.dk of Denmark to
supply an HVDC Light® (high-voltage direct current)
converter solution to support the interconnection
of the Norwegian and Danish power grids.The 500 kV
(kilovolt) link is a new record in transmission voltage
using this technology.
The underwater link will boost transmission capacity
between the mainly hydroelectric-based Norwegian
system and the wind and thermal power-based Danish
system. It will enable both networks to add more
renewable energy to their energy mix, and to use
electricity more efficiently.
ABB will design, supply and commission two 700 MW
(megawatt) converter stations based on the company’s
leading-edge HVDC Light® technology.The converter
stations will be located at both ends of the 240-km
long interconnection, and will be situated at the
same site as the existing converter stations for
Skagerrak 1-3 previously supplied by ABB, in Kristiansand,
Norway and Tjele, Denmark. The bipolar link will
be operated with the Skagerrak 3 transmission system.
An advanced control system is key to optimizing converter
performance, and ABB will install its world-leading
MACH2 control system. The project is scheduled for
commissioning in 2014.
“This HVDC Light solution will boost power
capacity, enable better load balancing in both grids
and help draw more renewable generation into the
energy mix,” said Peter Leupp, head of ABB's
Power Systems division. “It will also reduce
the impact of power system disturbances and contribute
to the stability and reliability of the grids. The
higher voltage level will also help minimize transmission
HVDC Light® continues to be a preferred choice
for underground and underwater long-distance power
interconnections as well as new applications, such
as providing mainland power supplies to islands and
offshore oil and gas platforms, city center in-feeds
where space is scarce, and more recently in the integration
of renewable energy generation from sources such
as land based and offshore wind farms.
Controllability, compact modular design, ease of
system interface and minimized environmental impact
are some of the key advantages of this technology.
These systems help overcome distance and grid constraints
while ensuring robust performance, power quality
and minimal electrical losses. In the rare case of
a power system outage, the technology’s ‘black-start’ capability
allows for fast network restoration using power from
the other end of the link. ABB leads the way in this
technology and has delivered 20 such converter stations
across the world.
