A windsturbine with their harvests the energy of winds rotor, converts it into electrical energy and feeds it into power grid. Also use the designations winds power plant, sometimes winds power converter (CHP), colloquially windsturbine or winds mill (wind turbine maintenance Idaho). Small plants that can be economically isolated operation are treated under winds generator; winds-driven pumps.
Like all machines can not reach windsturbines, the theoretical maximum. Aerodynamic losses resulting from air friction on the leaves, by vortices at the blade tips and swirl in wake of rotor. In modern systems, these losses reduce the power coefficient of cp, Betz 0.593 on cP equals 0.4 to 0.5. Of above 320 W / m ie up to 160 W / m expected. A rotor with 113 m diameter (10,000 m) is then 1.6 megawatts to shaft. To calculate the power at the mains addition, the efficiencies of all mechanical and electrical parts must still be considered.
Its simple, rugged design with a vertical axis of ten meters high and four arranged on a circle of eight meters in diameter Sailing a modest efficiency. Almost simultaneously, Charles F. Brush in Cleveland, Ohio oriented with a 20-meter-high plant at the time quite advanced windsmill technology. When it comes mills rather than on the torque on the speed; Brush used a two-stage translation with belt drives to drive a 12 kW generator.
Enercon was initially a long time the only manufacturer with direct drive. Several manufacturers are now set a gearless design. In 2013, the global market share of gearless plants was 28.1%. Windsturbines was made by around 2010 by stationary dock assembly; Since then, manufacturers on cost grounds increasingly on mass production assembly line techniques and industrialization and standardization ofir products.
Parallel to sit down - as in automotive industry has long been standard - modular platform strategies through, which are developed on the same technical basis of plant types or variants for different winds classes; z. B. By different rotor sizes with largely identical or different powertrain concepts generator with the same rotor diameter.
To a renaissance of winds energy came from the 1970s, among others as a result of environmental and energy debate and two oil crises. In some countries (such as Germany and the USA, among others) were reacted first to demanding industrial projects such as the two-leaf GROWIAN; but these had major technical problems and proved to be failures.
This energy is transported by the winds. In free flow far ahead of rotor of windsturbine, the power density of this transport. Due to this sharp increase in power density with the winds speed winds energy sites are particularly interesting. The tower height plays an important role, especially in inland areas where (buildings and vegetation) reduced the winds speed and increases the degree of turbulence.
The performance of a winds rotor is usually expressed by its power is supplied to shaft relative to rotor surface and on the power density of winds. This fraction is referred to by Albert Betz as a power coefficient cp, colloquially called harvestable. He led the early 1920s from basic physical principles from a maximum achievable power coefficient.
