OFFSHORE WIND RESOURCE- AND ENERGY YIELD ASSESSMENTS
(accredited acc. to DIN EN ISO/IEC 17025:2005)
For the effective planning of your offshore
wind farm project, EuroWind provides - based on the internationally accredited model system WIEN - detailed wind resource- and energy yield assessments and optimizes the configuration
of your wind farm.
For offshore assessments EuroWind statistically evaluates all available wind measure-
ments. In addition, reanalysis data, such as e.g. data of the NCAR/NCEP project, can be consulted in order to determine and complete the existing measuring data (the adjoining figure shows the long term average wind speed of the NCEP reanalysss).
Regional variations of the long-term average wind speeds over the North Sea and the Baltic Sea using the example of NCEP/NCAR reanalyses.
By using the program system WIEN (accredited acc. to DIN EN ISO/IEC 17025:2005) it is guaranteed that the model results are best possible adapted to the measuring data in the simulation area and that they correspond to the local conditions of the region even at those places where no long-term wind measuremnts are available. This is achieved by predefining the physical drive mechanisms, such as e.g.
roughness parameterization depending on the sea conditions,
thermal temperature profile above sea,
wind statistics from several sites
to the three-dimensional atmospheric flow model as input data.
Since the wind field within offshore wind farms are
not only significantly influenced by the local conditions
but also by the superimposed synoptic weather conditions,
the wind field simulations are being performed for
larger areas of about 150 km x 150 km.
Roughness parameterization depending on the sea conditions
Consideration of the thermal layering above sea
Consideration of wind statistics from multiple different sites
Application of an advanced three-dimensional flow model
Exact vertical wind profile also for large hub heights
