GE and TenneT have installed two 685 MVA power transformers at the Dorpen West converter station for the DolWin3 HVDC offshore wind grid link.
The 685 MVA power transformers were designed, built and tested at GE’s Monchengladbach factory in Germany.
GE said each unit is equipped with a tap changer to adjust individual power flows so that associated voltage fluctuations in the mains can be levelled out.
The Dorpen converter inverts the electricity transmitted from the offshore converter station DolWin Gamma and feeds it into TenneT’s extra-HV network.
GE said the overall DolWin3 project is on schedule to be completed in 2017.
GE Grid Solutions Central Europe region general manager Gerhard Seyrling said: “We are on track with the project, from the construction of the onshore and offshore converter stations to the assembly of the connecting cables.”
