Frequency distribution of turbulences
Our last post showed that the turbulence rose and the wind frequency rose are particularly noticeable in the wind directions in which other wind turbines of the wind farm are located. The turbulence intensity is comparatively high (usually greater than 15%) and the wind frequency comparatively low from these shaded wind directions.
The statistical frequency distribution of the turbulence intensity can now be viewed in a histogram plot. If you integrate the area on the right of 15%, you get a specific percentage that indicates the proportion of the operating hours that the system was shaded.
In this case, about 23% of the time the system was shadowed.
