In order to estimate the minimum distance between turbines and their safe position, a turbulence report is required. Turbulence intensity, which is defined by the relation of the standard deviation and the median value is an important measurement value. As long as measurements were taken at the site, we calculate the ambient turbulence for our customers and then produce a turbulence report. For this we work according to the IEC 61400-1 requirements as well as those of the Bundesverband für WindEnergie e.V. The transfer of the turbulence at the site to the planned turbines is carried out with the three-dimensional, non-linear meteodYn model.
