The Jindo–Jeju HVDC system is a 105 km HVDC submarine cable connection in South Korea between the island of Jindo, close to the Korean Peninsula, and the more distant island of Jeju. The system has a capacity of 400 MW and transmission voltage of ±250 kV and was put into service in 2014. It is the second HVDC link to Jeju Island, after the Haenam–Cheju link completed in the late 1990s (the spelling of the island’s name was changed from Cheju to Jeju in 2000). The converter stations use Line-Commutated Converters with a conventional arrangement of a single Twelve-pulse bridge per pole.
