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.
In addition, the rotor diameter is greater. A doubling of rotor blade length effected according to circle formula to quadruple the rotor surface. Until the late 1990s, the diameter was usually less than 50 meters, by around 2003 mostly between 60 and 90 meters. Since 2008, often come windsturbines with rotor diameters exceeding 90 meters used, which in 2012 the average value of new was installed systems.
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.
To estimate the annual income the so-called average windspeed is given for the location windsturbine. It is an average winds velocities occurring over the year. The lower limit for the economic operation of a system is dependent on the feed-in tariff, at an average windspeed of 5-6 m / s at hub height. However, other factors need to be considered.
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.
About calculation programs on the internet can be the income of certain investments to be elected under conditions determined approximately. However, information on the actual income of a site can be only on winds measurements based winds reports. In this case, the degree of turbulence due to geological conditions, vegetation, higher buildings or adjacent windsturbines must be considered.
The yield reduction due to reduced winds velocity and turbulence behind other windsturbines is called a wake or terminal loss. Since the power supply increases with the cube windsspeed, it is useful to introduce the system for a significantly higher than the mean windsspeed.
Their rated power, sometimes called the installed capacity reaches a windsturbine at the rated windsspeed. In capacity of plant is kept constant in order to avoid overloading. At very high windsspeeds (storm), the system is completely switched off. With a slight crescent shape in outer region of rotor blades soft gusts from the blade tips to leeward. The associated distortion of sheets reduces the angle of attack and therefore the winds load. Accordingly, material can be saved
