All wind farms operate on the same principle:
- Wind wheel (rotor), converts the incident wind flow energy into mechanical energy of rotation of the turbine axis . Rotor diameter varies from a few meters to several tens of meters. Rotational speed is from 15 to 100 rev / min. Typically, grid connected wind turbine wind wheel speed constant. For autonomous systems with rectifier and inverter - usually variable ;
- Multiplier - intermediate between wind wheel and an electric generator, which increases the speed of the wind wheel shaft and secures agreement with the generator speed. The exception is a low-power wind turbine generators with special permanent magnet; wind turbines in such multipliers are not commonly used;
- Tower (sometimes strengthen steel braces), which established the wind wheel. At high power wind turbine tower height is 80 meters is usually cylindrical mast, although used and lattice towers;
- Foundation ( foundation) is intended to prevent the fall of the installation in a strong wind . Furthermore, to protect against damage by strong gusts of wind and hurricanes almost all high power wind turbines stop automatically if the wind speed exceeds the limit.
