Accredited system for wind- and energy yield assessments
for WInd ENergy
turbines
On the basis of the model system WIEN, the
EuroWind GmbH is offering wind resource- and energy yield assessments as well
as area-wide wind potential studies for your wind farm project
in Germany and abroad. The computation procedure has
been developed in order to fulfill the higher requirements
for energy yield assessments at complex sites - on- and offshore.
WIEN is internationally accredited according to DIN EN ISO/IEC 17025:2005 and is successfully applied for climatological wind resource- and energy yield assessments since 1997 to improve your strategy in the field of designing and financing planned wind
farm projects.

Procedures
The prognosis system is based on the combination of
a complex three-dimensional wind field simulation model
with a statistic-dynamic climate model. This comprehensive
procedure is able to forecast the climatological wind
conditions at any site, even without the availability of on-site long-term wind measurements.
The physics of the flow model allows taking into consideration
the influence of the topography on the wind field in the boundary layer for different weather situations. The
ground characteristics are having a considerably higher
influence on the wind field during high pressure
weather conditions with low wind speeds, as, for example, during a distinct weather
situation with westerly winds. The wind energetic characteristics
and energy yields can be computed for the site analysis
for optional turbines and hub heights
(Figure 1).
Comprehensive three-dimensional wind field simulations of the prognosis system WIEN allow to provide wind energy yield assessments as well for large hub heights of more than 100 meters as for sites in complex low mountain ranges or for exposed offshore sites.

Results
Besides the climatological wind resource- and energy yield assessments for
individual wind farms we can also provide an identification
of the existing profitable areas for your individual
area of investigation. Especially for areas which are, up to
now, poorly developed in terms of wind energy, this
is offering a cost-efficient and time-saving possibility
to identifyt appropriate sites (figure 2).

Validation
The very high quality of the prognosis of our model system WIEN is proven by comprehensive validation results. The forecast quality is ensured by the individual calibration of the simulation results with measured wind statistics (figure 3). The best results are achieved by using wind statistics from close to the ground.
