Abstract:
The"Database on Wind Characteristics" is established in 1998 in an EU subsidised
project. This database is presently operated as a project of the International
Energy Agency, IEA Wind R&D Annex XVII. The database constitutes
a valuable tool for a consistent and rational calibration of essential
wind characteristics for wind turbine design. In addition, investigations
of a more fundamental and phenomenological character can conveniently
be supported by the large selection of full-scale wind field measurements
contained in the database. At the start of the project, the partners
in the Annex agreed that additional wind data were needed to complete
the data selection. Most important data were identified as additional
wake measurements, three component offshore measurements suitable for
validation of especially the low frequency part of offshore wind spectra,
additional combined wind- and wave data from representative offshore
locations, extreme complex terrain measurements and long term data sets
covering time spans of at least 20 years.
The Dutch partner in the IEA Annex XVII, ECN, has provided several data
sets to the database. This report describes the work that has been done
over the project period, from September 1st 2002 to June 1st 2004. During
the project, data have been added by ECN to the international wind database.
These data have been described in earlier reports [1] and [2]. In addition,
analyses have been performed on the data, which is described in [2].
