DeWind is a German company owned by Daewoo who design and manufacture wind turbines.
The D8.2 Turbine has been developed based on the previous D8 and is in production since 2006.
The plant has been equipped with a hydrodynamic windrive Gearbox.
This allows the variation of the rotor speed independent of generator speed. A decoupling of generator rotation speed and grid frequency becomes redundant by this means.
The synchronous generator of this turbine is coupled directly with the grid. The system is unique on the wind energy market.
According to DeWind it is advantageous regarding the quality of fed-in electricity as well as regarding behaviour in case of grid failure.
Also, patents of the wind turbine producer GE Energy are not violated with this technology. The turbine is offered with 50 Hz as well as 60 Hz design.
