The new HVDC power link features ‘black-start’ capability in order provide faster grid restoration in the event of a blackout.
The black-start system, which can replace local auxiliary power supply needs such as diesel generators, has been tested prior to the delivery.
During the Åland real-time simulation trial, the power supply was restored with an automatic start-up sequence following a planned suspension.
ABB Power Systems division Grid Systems business head Patrick Fragman said: "We are pleased to hand over this project, and demonstrate the innovative ‘black start’ feature embedded in our cutting-edge HVDC technology – a key focus area of ABB’s Next Level strategy.
"The link will deliver clean energy and enhance security of power supply to the inhabitants and we are grateful to the community for their support in conducting the real-time simulation."
Designed to supply power to 28,000 inhabitants, the Åland link can transmit renewable energy between mainland Finland and the archipelago, which lies between the Finnish west coast and Swedish east coast.
In addition to enabling integration of more renewable energy, the HVDC Light link will provide power supply security and grid reliability to Åland while reducing co2 emissions.
The delivery is a part of a $130m contract awarded to ABB in 2012 which involved supply of two 100 MW, ±80 kV HVDC Light converter stations for installation in Ytterby, Åland and the other in Nådendal, Finland.
Capable enabling underground and subsea transmission, the HVDC Light technology provides several environmental benefits including neutral electromagnetic fields, oil-free cables and compact converter stations.
