WebSep 9, 2012 · When an individual turbine is being considered, performance is typically expressed in terms of a power curve, which relates power production to hub-height wind speed and assumes that there is one value of turbulence intensity. If there is no change in wind direction with height, high turbulence will lower the power curve near the rated speed. WebA variable speed wind turbine is one which is specifically designed to operate over a wide range of rotor speeds. It is in direct contrast to fixed speed wind turbine where the rotor speed is approximately constant. The reason to vary the rotor speed is to capture the maximum aerodynamic power in the wind, as the wind speed varies.
