WAsP has been employed for more than 20 years within wind power meteorology and in the wind power industry – and has become the industry-standard PC-software for wind resource assessment and siting of wind turbines and wind farms. WAsP runs on Windows 2000, XP, Vista, and 7.
The WAsP software package
The WAsP software package consists of four Microsoft installer files: the WAsP program, the WAsP Climate Analyst, the WAsP Map Editor and the WAsP Licencing System.
The WAsP installation program also installs the WAsP Turbine Editor, a complete set of sample data files, several demonstration projects and the Danish Wind Atlas. Documentation is included as on-line help files.
The wind atlas methodology
WAsP is a PC-program for the vertical and horizontal extrapolation of wind climate statistics. It contains several physical models to describe the wind flow over different terrains and close to sheltering obstacles. WAsP is an implementation of the so-called wind atlas methodology, which may be summarised as follows:
time-series of wind speed and direction —> observed wind climate (OWC)
observed wind climate + site description —> regional wind climate
atlas data sets)
regional wind climate + site description —> predicted wind climate (PWC)
predicted wind climate + power curve —> annual energy production (AEP)
of wind turbine
Wind farm production
predicted wind climates + WTG characteristics + wind farm layout —>
farm wake losses
annual energy productions + wake losses —> net annual energy
