WebCharacteristic power–speed curves of two wind turbines. Some authors use analytic curves with linear, quadratic or cubic forms, or a combination of these, to represent the power curve PWT (v) of a wind turbine ( Haslett and Kelledy, 1981; Koeppl, 1982; Jones 1986, 1988; Celik, 2003; Chang and Tu, 2007). 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. peace n plenty
