HVDC HelWin2
HVDC HelWin2 is a high voltage direct current (HVDC) link built to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 690 MW, ±320 kV are used and the total cable length is 130 km. The project was built by the Siemens/Prysmian consortium with the offshore platform built by Heerema[1][2] in Zwijndrecht, Netherlands. The topside measures 98 m x 42 m x 28 m and weighs 10200 tonnes. The project was handed over to its owner, TenneT, in June 2015, the fourth such project to be completed in 2015.[3]
