In mid-November, transmission system operator TenneT connected the offshore wind farm (OWF) Veja Mate to BorWin2. TenneT’s offshore grid connection system BorWin2 has been in operation since January 2015. It consists of the converter station BorWin beta, where the alternating current (AC) of the connected wind farms is transformed into direct current (DC). From BorWin beta the direct current flows via 125 kilometres of sea cables and 75 kilometres of land cables to the converter station in Diele, where it is transformed in AC again and fed into the high voltage grid. BorWin2 has a capacity of 800 MW and is already connecting the OWF Global Tech I to the high voltage grid.
The connection between BorWin beta and Veja Mate’s substation is realised by two 11,4 km AC cables with a voltage of 155 kV. TenneT and Veja Mate carried out the so called Soak Test, a 24 hours high voltage cable quality test, from 16 to 17 November and completed it as planned.
“We had a very ambitious schedule”, says Wilfried Breuer, Executive Manager at TenneT, “but thanks to the good team work between TenneT and Veja Mate and the continuous support and confidence which our shareholder in this project, Mitsubishi Corporation, placed in our project team we managed to connect Veja Mate’s substation in time to the grid.
For TenneT this step marks the successful completion of Veja Mate’s connection to the grid. As Veja Mate’s turbines are still to be erected, the wind farm will use the grid connection in the construction phase to obtain power for their construction works from the grid. .
Lutz Falta, Veja Mate Electrical Package Manager, said “Throughout the whole project, TenneT and Veja Mate managed to keep an atmosphere of good cooperation which helped both parties achieve their goals. Even in the most difficult situations, TenneT proved to be a solution and customer oriented provider to our satisfaction.”
