Title : PARAMETERISATION OF TURBULENCE INTENSITY
Authors : Kurt S. Hansen and Gunner Chr. Larsen

Summary :
In order to continue cost-optimization of modern large wind turbines it is important continuously to increase the knowledge on wind field parameters relevant to design loads. This paper contains a parametrisation of the turbulence intensity at given sites, relevant for fatigue loading of wind turbines. The parameterisation is based on wind speed measurements extracted from the “Database on Wind Characteristics” (www.winddata.com). The parameterisation has been based on the LogNormal distribution, which has proven to be a suitable distribution to discribe the turbulence intensity distribution.
