CT: The power curve verification is important for both power output optimization and contractual promising check for wind energy producers. However, the traditional power curve verification by IEC61400-12A is costly and time consuming due to the meteorological metmast tower installation on test sites.
The newly published IEC61400-12B gives the possibility of verifying the power curve and AEP (Annual Energy Production) by the existing anemometers on the wind turbine nacelle. The purpose of this project is to investigate how is the validation of power performance method by IEC61400-12B under different weather conditions (wind shear / temperature /
Turbulence intensity / wind direction variation) and different types of terrain (Complex or flat terrain at site).

N: 1. 1727, from anemo- (before vowels anem-, word-forming element meaning “wind,” from comb. form of Greek anemos) “wind” + -meter (word-forming element meaning “device or instrument for measuring;” commonly -ometer, occasionally -imeter; from French -mètre, from Greek metron “a measure”).
2. The anemometer on a wind turbine is really only used to determine whether there is enough wind to make it worthwhile to yaw the turbine rotor against the wind and start it.
