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.
The consideration of several windsturbines can be found in article winds farm, more applications and energy aspects in Articles Winds Energy, Renewable Energy and Energy Transition. The first documented system for power generation Established in 1887, the Scotsman James Blyth to charge batteries for lighting his holiday cottage.
Analog increased the average hub height and power ratings up to first half of 2014 to 113 m and 2.65 MW and a rotor diameter of 97 m, with significant differences due to regional winds speeds. Modern windsturbines have become weak rotor diameter to about 130 meters and hub heights up to 150 meters, the total amount of investment shall not exceed 200 m far in most cases. In offshore area (as of 2013) systems with a rotor diameter of 170 meters in test mode.
The Dane Poul la Cour came in 1900 through systematic experiments - among others aerodynamic airfoil in winds tunnels - the concept of speed engine, in which only a few blades sufficient to exploit the energy of flow over the entire rotor surface. During the First World War, over 250 plants of this type in Denmark were in operation. In other countries winds engines were built for decentralized power generation in early 20th century. With the widespread electrification in interwar period, many ofse plants disappeared, equipped with DC generators and battery saving winds engines were not compatible with the AC power grid since.
After the Second World War, the winds energy research has been driven in different states. States such as France and Britain invested until c. 1965 heavily in winds power research. The promoted by the aviation improving the profile geometries in 1950s and 1960s to glide ratios well over 50 allowed extreme high speed with only a single rotor blade. Rotors with more than two leaves were regarded as backward. In view of low energy prices barely plants were built, with the exception of a few prototypes.
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 exported also to thousands in 1980s in US plants had three rigid rotor blades (= no rigid blade angle adjustment) and a grid-connected inverter without phase machine with one or two fixed speeds. The capacity limitation was performed by flow separation. Archetype of this very successful concept was designed by Johannes Juul and in 1957 commissioned in Gedser windsturbine. It worked reliably up to its preliminary decommissioning in 1966 and was in late 1970s put back into service for a joint test program by scientists and NASA .
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.
