HVDC DolWin2 is a high voltage direct current (HVDC) link under construction 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 900 MW, ±320 kV are used and the total cable length is 135 km. The project is similar to the HVDC DolWin1 project but has a slightly higher power rating and uses a different design of offshore platform. The platform topside was built by Drydocks World in Dubai〔( Drydocks World reinforces its leadership in offshore construction with the completion of the pioneering mega structure – DolWin beta ), Drydocks World website, 10 June 2014.〕 and transported to Europe in the summer of 2014〔(Smit Lamnalco Aid in DolWin Beta Transport ), Offshore Wind.biz, 22 July 2014.〕 to be fitted out at Haugesund in Norway.〔(DolWin Beta to Arrive in Haugesund Tonight ), Offshore Wind.biz, 21 August 2014.〕〔(DolWin Beta Becomes Resident of North Sea (Gallery) ), Offshore Wind.biz, 2 September 2014.〕〔(Photo of the Day: Work Underway on DolWin Beta ), Offshore Wind.biz, 17 November 2014.〕 The platform, which is of a floating, self-installing design not previously used in an HVDC project, sailed out from Haugesund on 1st August 2015〔(Dolwin beta on the move ), ABB Group Press Release, 1 August 2015. 〕 and was installed in the North Sea ten days later.〔(ABB installs world's most powerful offshore converter platform in the North Sea ), ABB Group Press Release, 10 August 2015.〕 The overall project is being built by ABB and is expected to be handed over to its owner, TenneT, in 2016. ==See also== *High-voltage direct current *Offshore wind power *HVDC BorWin1 *HVDC BorWin2 *HVDC BorWin3 *HVDC DolWin1 *HVDC DolWin3 *HVDC HelWin1 *HVDC HelWin2 *HVDC SylWin1 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HVDC DolWin2」の詳細全文を読む スポンサード リンク
