ABB is working with SEV, the main electrical power producer and distributor for the Faroe Islands, to deliver innovative synchronous condenser technology that will stabilize its power grid as renewable generation replaces fossil-fueled plant. The first SC unit is currently being commissioned on the island of Suðuroy. SEV has now placed an order for a similar unit to be located at Sund on Streymoy, the Faroes’ largest and most populous island. Switching off the existing diesel-fueled generating plant could impact the stability of SEV’s grid. This is because the rotating equipment provides vital “spinning inertia” that keeps the system in balance. A particular challenge is that there are no power cables connecting the Faroe Islands to neighboring countries so its grid is unable to use external support. To tackle this challenge, ABB is working with SEV to deliver innovative technology in the form of synchronous condensers. An SC is a rotating electrical machine that provides vital services to strengthen a power system and keep it stable as both loads and renewable energy production change. These services include inertia, fault level and reactive power for voltage regulation.
