GE implements upgrades on DolWin gamma in North Sea

Germany, Manheim: GE Renewable Energy’s Grid Solutions business announced the offshore grid connection DolWin3 in the North Sea was recently successfully upgraded.

The upgrades included enhancements to the valves and control system. In addition to improving the overall performance of the grid connection system, the upgrades also reduce maintenance.

Located approximately 80 km from land, DolWin3 with the offshore converter platform DolWin gamma connects Merkur Offshore wind farms and Borkum Riffgrund 2 in the south-western part of the German North Sea with the onshore transmission grid.

The DolWin3 project uses voltage source converter technology, the newest HVDC technology featuring highly specialised power electronics, which allows for enhanced operational capability and greater power and frequency control, compared with line commutated converter technology.

“The completion of the final certification tests for DolWin3, along with our recent award of the Sofia HVDC link, are further evidence that GE’s Voltage Source Converter technology is now well established and that GE has the ability to commercially deliver on these solutions,” said Raj Iyer, Head of Grid Integration Solutions for GE’s Grid Solutions business.
