Overview

DeWind was established in 1995 and since that time has delivered over 550 Wind Turbines,
with a total nominal output of more than 500 MW. Early adopters of variable pitch
combined with variable speed operation wind turbines were designed to obtain the
maximum energy yield from the wind. The D4 was introduced in 1996 as a 500 kW turbine
but was later upgraded to a rating of 600 kW. Over two hundred and sixty D4s have been
installed to date. In January 1999, the first D6 was commissioned and since then some
two hundred and forty D6 turbines have been installed. In 2002 the first D8 2 MW turbine
was installed with its distinctive Porsche designed Nacelle.

The current product range comprises three models of Wind Turbines; the D6 50 Hz
with a nominal output rating of 1.25 MW; the D8 50 Hz with a nominal output rating of
2.0 MW and the D8.2 2,000kW 60/50Hz with a Synchronous generator that connects
directly to the grid.

The DeWind D8.2 is an evolution of the DeWind D8 turbine. The DeWind D8.2 integrates the advanced WinDrive® hydrodynamic torque converter developed by Voith Turbo and a Cummins Synchronous generator. The WinDrive® and generator combination is attached to the D8’s proven drive train and connects directly to the power grid at up to 13.8 kV without the use of power conversion electronics.

The first DeWind D8.2 Prototype was installed in December 2006 in Cuxhaven, Germany and commissioned in January 2007. It has received a Statement of Compliance for Design Assessment, according to Dibt Wind Zone III conditions from DEWI-OCC. The first 60 Hz demonstrator will be installed in Sweetwater, Texas at the end of 2007.

Serial production of the DeWind D8.2 will take place in the USA at the TECO Westinghouse facility in Round Rock, Texas. DeWind is leveraging TECO Westinghouse resources and experience in assembling large capital goods. The facility is fully ISO 9000 certified and will allow DeWind to assemble turbines to exacting quality standards.

DeWind D6 (50 Hz only)

The DeWind D6 is a well proven three-blade upwind turbine with pitch control and horizontal axis. The turbine has a rated power of 1.25 MW and can be supplied with different rotor diameters and different hub heights to suit the par­ticular site conditions and planning requirements. The outstanding features of the DeWind D6 are effective utilization of available wind, quiet operation, good grid compatibility and attractive design. The turbine operates with variable rotor speed and is thus capable of producing electric power efficiently at low wind speeds, and utilizing the energy of gusts without overloading the grid or turbine components.

DeWind D8 (50 Hz only) 

The DeWind D8 is a proven three-blade upwind turbine with pitch control and horizontal axis. The turbine has a rated power of 2.0 MW and can be supplied with different hub heights to suit the particular site conditions and planning requirements. The outstanding features of the DeWind D8 are effective utilization of available wind, quiet operation, good grid compatibility and attractive design. The turbine operates with variable rotor speed and is thus capable of producing electric power efficiently at low wind speeds, and utilizing the energy of gusts without overloading the grid or turbine components.

DeWind D8.2 (50 and 60 Hz)

The DeWind D8.2 is a three-blade upwind turbine with pitch control and horizontal axis. Evolved from the D6 and D8 lines, it incorporates many lessons learned along with advanced new features. The turbine has a rated power of 2.0 MW and can be supplied with different hub heights to suit the particular site conditions and planning requirements. The outstanding features of the DeWind D8.2 are effective utilization of available wind, quiet operation, good grid compatibility and attractive design. The turbine operates with variable rotor speed and is thus capable of producing electric power efficiently at low wind speeds, and utilizing the energy of gusts without overloading the grid or turbine components. The directly connected synchronous generator with its inherent fault ride-through and other grid support capabilities, without reliance on power electronics, make it an attractive option for grid operators.
