Germany, Bremerhaven: Siemens has introduced a new solution for connecting offshore wind turbines to the grid, a direct-current technology enabling a cost-efficient and simplified connection of offshore wind power plants far from the coast.

With the new solution, a direct-current cable can connect several smaller platforms sequentially in a wind farm and then route them to an onshore transformer substation, the company states in the press release.

The core of the new transmission technology consists of the DRU (diode rectifier unit), the transformer, the smoothing reactor, and the rectifier – all combined in one tank.

According to the company, the use of the DRUs and the encapsulated DC-CS direct-current switchgear decreases the installation space by more than 80 percent compared with air-insulated technology.

Also, for the first time Siemens is using biodegradable ester liquids in the DRU to insulate high-voltage direct-current equipment.
