Siemens Energy will install a turnkey grid connection in the North Sea for the SylWin cluster for Dutch-German transmission grid operator TenneT.
Through a partnership with Italian cable manufacturer Prysmian Powerlink, Siemens will connect DanTysk via the SylWin collective connection. Equipped with 80 Siemens wind turbines, DanTysk will have a total capacity of 288 MW.
The wind farm will be connected to the mainland grid via a high-voltage direct-current (HVDC) transmission link using subsea and underground cable.
TenneT has estimated the total investment at approximately 1 billion euros. The grid connection is scheduled to be ready for operation by early 2014.
The HVDC system, transformers and gas-insulated high-voltage switchgear will be installed on an offshore substation platform for energy-efficient transmission of the electrical energy generated by the wind farm to the mainland.
The alternating current produced by the wind turbines will be converted to direct current on the platform, which will later be located directly adjacent to the wind farm in the North Sea. The direct current will be brought to a transmission voltage of 320 kV.
