BorWin Gamma
BorWin gamma is an offshore platform in the German Exclusive Economic Zone in the North Sea , which serves as a converter station for high-voltage direct current (HVDC) transmission "BorWin 3".
Location
The BorWin gamma converter platform is 90 kilometers north of the island of Borkum on the southern corner of the Hohe See offshore wind farm (EnBW Hohe See).
history
In December 2010, the network operator TenneT TSO applied for the construction and operation of this converter platform to the responsible Federal Maritime and Hydrographic Agency (BSH) together with the HVDC BorWin 3. Approval took place on June 29, 2017. The platform was set up in October 2018. The test operation began in August 2019. Since February 2020 BorWin gamma has been "officially" online.
HVDC converter platform BorWin gamma
The electrical systems on the BorWin gamma offshore platform convert the three-phase current from the offshore wind farms “Hohe See” with 400 MW, “Albatros I” with 50 MW and “ Albatros ” with 345 MW into direct current before it is transmitted to shore .
The Drydocks World shipyard in Dubai received the order to build the platform from the manufacturer consortium Petrofac and Siemens . The electrical equipment is provided by Siemens.
background
The systems on HVDC converter platforms work in this harsh environment with clean room technology. The superstructures built in a shipyard were mounted as so-called "top side" on the foundations in the sea. They are around 20 to 25 meters above the surface of the water.
The overall system consists of the transformer platforms of the individual wind farms, the cable connections from these transformer platforms to the HVDC converter platform, the systems on this platform for converting the three-phase current into direct current, the direct current submarine cable and a converter station on land. The 600 kV direct current line (BorWin 3) will connect BorWin gamma to the new shore-side converter station Emden-Ost. Here the direct current is converted back into three-phase current and fed into the 380 kV transmission network of the TenneT TSO via a switchgear.
