DeWind is an internationally active producer of wind power plants, originating in Germany. The company was founded in 1995 and is based in Irving, Texas, and Hamburg, Germany. DeWind has the legal form of a corporation, and, since September 2009, it has been a subsidiary company of Daewoo Shipbuilding and Marine Engineering (DSME), a large shipbuilder based in Korea. Manufacturing takes place in Lübeck and Round Rock, Texas. More than 900 DeWind turbines have been erected worldwide, with a total capacity of over 1600 MW. == Turbine types == The first produced wind turbine was the D4 1996, with a capacity of 500 kW (later 600 kW). In 1999, this turbine was followed by the D6 with 1 MW capacity. In 2000, the capacity of this plant was increased to 1.25 MW.〔(Technical Data D6 )〕 After a development period of two years, in 2002 the D8 went into production with a capacity of 2 MW.〔(Technical Data D8 )〕 Already in the mid-1990s, the D4 was produced with active pitch regulation as well as a doubly fed induction generator. This technology proved itself and, therefore, was implemented in the following models D6 and D8. Especially advantageous are the decoupling of the rotational speed of the turbine rotor and the grid frequency. By using the inertia of the turbine rotor, it reduces mechanical loads on turbine components and prevents peaks in electricity feed-in. The D8.2 has been developed based on the D8 and has been in production since 2006. The plant has been equipped with a hydrodynamic windrive〔(Technical Data 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.〔(Technical Data D8.2 )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DeWind」の詳細全文を読む スポンサード リンク
