Methodology V: GWS® Windnode und GWS® DATA von Al-Pro


GWS® Windnode

Weibull distribution for 12 individual sectors

For each of the 12 sectors of a site the calculated wind velocity distribution by the GWS® mesoscale modeling will be approximated by the Weibull distribution. The A and k values (and thus the mean wind velocity) thereby determined are given for each sector in the lower part of the windnode report.
A park calculation can be performed using the A and k parameters for the 12 sectors. As the underlying wind velocity distribution is based on values from a mesoscale simulation (with resolution of 2 x 2 km!), the determined park yields can only be interpreted as rough estimates! The sectorwise display of the wind velocity distribution can on the other hand help to establish or optimize a first park layout by indicating the main wind direction.
The windnodes (and the GWS® wind maps) can be used for accredited wind studies, when they are validated and eventually scaled with real energy yield data of adjacent wind turbines or wind measurements.

GWS® DATA

Frequency table

For each of the 12 individual sectors the frequency of the wind speed values in bins of 1 m/s are given, based on our GWS® mesoscale modeling (with resolution of 2 x 2km!).
GWS® DATA offers direct access to the GWS® database and provides digital meso-scale input data for wind flow simulations - for any model system.
