GE implements successful upgrades on converter platform DolWin gamma

Wednesday, October 14 2020

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

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

Located approximately 80 kilometers from land, DolWin3 with the offshore converter platform DolWin gamma connects the wind farms Merkur Offshore, containing 66 Haliade 150-6MW GE Renewable Energy wind turbines, and Borkum Riffgrund 2 in the south-western part of the German North Sea with the onshore transmission grid.

“The offshore grid connection DolWin3 has been transferring power from wind generation in the North Sea to the German grid since the third quarter of 2018. The updates that have recently been tested and certified give us confidence that our grid connection will still be stable and reliable in the future as we move toward our ultimate renewable energy goals in the future,” said Marco Kuijpers, Director Large Projects Offshore of TenneT. “In all these years of trustful cooperation, we have always had a solution-oriented partner in GE.”

The DolWin3 project uses Voltage Source Converter (VSC) technology, the newest HVDC technology featuring highly specialized power electronics, which allow for enhanced operational capability, greater power and frequency control, compared with line commutated converter (LCC) technology.

“The completion of the final certification tests for DolWin3, along with our recent award of the Sofia HVDC link, is 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. “The DolWin3 upgrades incorporate learnings from our recently released industry-leading second-generation VSC valve and eLumina control system.”
