Off the North Sea coast of Germany is an impressive array of wind farms that feed an enormous amount of renewable energy to the European power grid.
Due to their physical distance from land however, the medium voltage AC power generated by the individual wind turbines is first routed to a central point in the field where it is then transformed into high voltage AC and subsequently converted into DC power via a giant 25,000 ton platform-based converter station.
The converter room is the heart of the platform. This is where HVDC-Plus technology is used to convert the AC current generated in the wind farms into low-loss DC current. This is then transported to the mainland by marine cable, with minimal losses of less than four percent. The converter technology is installed in two separate converter rooms on the platform and also used on the land station. Image courtesy Siemens
The DC power, which incurs far less transmission losses than AC, is then routed shoreside via a power cable to the grid.
Siemens released a video today that describes this system:
The Trump administration has expanded its newfound strategy of unwinding offshore wind development through negotiated buyouts, announcing two new agreements that will see two projects give up federal offshore leases...
The Trump administration has struck a $928 million deal with TotalEnergies to abandon two major U.S. offshore wind leases and redirect the capital into LNG and oil and gas development, marking a decisive shift in strategy after federal courts blocked efforts to halt projects on national security grounds.
A string of federal court rulings has effectively unraveled the Trump administration’s attempt to halt offshore wind construction along the U.S. East Coast, with the latest decision clearing Ørsted’s Sunrise...
