WIND RESOURCE- AND ENERGY YIELD ASSESSMENTS (accredited acc. to DIN EN ISO/IEC 17025:2005)
EuroWind provides independent
and internationally accredited wind resource- and energy yield assessments as well as area-wide
wind potential
maps for your wind farm projects in Germany
and abroad. The in-house developed, optimized simulation procedure WIEN (accredited acc. to DIN EN ISO/IEC 17025:2005)
thereby ensures to comply with the increased demand in the
energy yield prognosis for wind turbines at complex
sites. Since 1997 our procedure for wind resource- and energy yield assessments
is successfully applied for planned on- and offshore wind farms - world-wide.
Therewith EuroWind deliberately renounces the standard
model WAsP for wind farm assessments in the midland.
Since the program system WIEN
is fulfilling demonstrably the advanced requirements of
complex onshore- and exposed offshore sites, our procedure is often also used
to recheck already existing energy yield assessments.
To simulate the wind con-
ditions that are
affected by the orography a three-dimensional
numeric flow model is being used and
combined with a sta-
tistical dynamical climate model.
This complex procedure is also able to assess
the climatological wind conditions for sites,
where no long term wind measurements
had been performed.
Marking of profitable areas by means of the results of our three-dimensional numeric flow modell
Being an active member
of the wind expert advisory board of the Bundesverband
Windenergie (Federal association of wind energy),
wind resource- and energy yield assessments by EuroWind comply with
the specifications supplied by the expert advisory
board concerning the quality and the scope of wind resource- and energy yield assessments. To our customers this mean approved, bancable results and an increased
reliability in planning for the design and financing of wind farms.
Following services are being offered in the range of wind- and energy yield assessments:
Detailed inspection of the site and the environment
Digitalization of the site and assessment of obstacles and the surface roughness
Inclusion of measured wind statistics from several sites
Inclusion of measured production data from neighbouring wind farms
Provision of the site-related wind speed
Provision of the site-related direction-depending wind speeds
Provision of the site-related Weibull parameters
Provision of the site-related vertical wind profiles
Provision of the site-related wind power density
Provision of the site-related wind roses
Provision of the site-related number of full load hours
Provision of the degree of efficiency of
the wind farm
Provision of the energy yield of the wind
farm
Provision of the losses by the wind farm specific shadowing effects
Optimization of the wind farm configuration
