Air density atmospheric stability equivalent wind speed Heating Poles and towers power curve Power measurement turbulence intensity wind profile wind shear wind turbine power Wind turbines
Wind turbine power performance for the energy production calculations has traditionally been modeled assuming a set of simple average input meteorological conditions. Wind turbine power curve tests are also performed with this assumption, based on criteria defined in the IEC-12-1 standard. While this approach has proven to be adequate for the wind industry for several years, the increasing size of wind turbines (WT)-coupled with an improved awareness of the wind flow variation throughout the boundary layer-has generated concern that the effects of complex meteorological conditions on turbine power performance are not well understood. However, the uncertainty of power performance measurements is closely related to the uncertainty in the wind velocity, turbulence and other meteorological parameters and their effects on the wind turbine performances.
