ABB to transmit wind power from North Sea

Switzerland, Zurich: ABB’s Power Grids business has been awarded a triple digit million-dollar order from the Aibel/Keppel FELS consortium, which will design, construct, and build the high voltage direct current (HVDC) transmission system for the offshore wind connection project DolWin5.

ABB is the HVDC technology provider. This project will deliver 900 MW of zero-carbon electricity – enough to power around 1 million homes – from three wind farms some 100 km off the German coast. It is scheduled for completion in 2024.

The order includes the converter platform in the North Sea, as well as an onshore converter station located in Emden, in the Lower Saxony region of Germany. TenneT is responsible for providing power links to the offshore wind farms in this cluster.

ABB’s HVDC solution is used to transport the power generated by offshore wind farms very efficiently by converting the alternate current (AC) to direct current (DC) on the converter platform. That makes it possible to transmit the power through a 130 km DC cable system with very low losses to the mainland.

With the use of ABB’s voltage source converter technology, commercialized under the name HVDC Light®, it is possible to keep the conversion losses very low. Additionally, the order will also include the ABB Ability™ Modular Advanced Control for HVDC (MACH TM), which is instrumental in controlling the complex connection between wind farms and the on-shore AC grid.
