Switzerland-based ABB group has won orders worth over $22 million from Vattenfall Eldistribution AB to upgrade the world’s first commercial high-voltage direct current (HVDC) power transmission link.
ABB will install its state-of-the-art MACH control and protection system, which is like the brain of an HVDC link. ABB’s MACH control system offers unmatched calculation capacity and a high degree of integration capability to handle control and protection functions, designed to run around the clock for 30 years or more. The cooling system will also be upgraded as part of the project. The upgrades replace aging equipment and will help improve security of power supply to the island.
The 150-kilovolt (kV) link has the capacity to transmit 320 megawatts (MW) of power 100 kilometers from Västervik, on the east coast of mainland Sweden, to Ygne, on the island of Gotland. The link provides electricity to meet the needs of the 58,000 residents of Gotland and enables wind power, generated on the island, to be transmitted to the mainland.
This upgrade will help enhance capacity and enable greater amount of wind power generation on Gotland, to be integrated into the grid for use both locally in Sweden and across borders.
