EMD is an appointed reseller of the WAsP Engineering software developed by DTU Wind Energy, Denmark.
The WAsP Engineering (WEng) software can be used independently or as an “internal calculation engine” within the windPRO SITE COMPLIANCE module for site suitability analyses.
WAsP Engineering is a linear flow model (LINCOM) to support the estimation of loads on wind turbines and other civil engineering structures situated in moderately complex terrain. The wind conditions that are treated are:
- Extreme wind speeds, e.g. the 50-year wind. If a wind turbine is well situated on a hill the mean wind speed and thereby the power production can be increased significantly compared to that over flat terrain. Unfortunately, the 50-year wind will increase correspondingly, maybe calling for increased strength of the blades or other parts of the turbine.
- Wind shears and wind profiles. Strong mean wind shears (large differences in the mean wind speed over the rotor) give large fluctuating loads and consequently fatigue on the wind turbine blades, because the blades move through areas of varying wind speed.
- Turbulence. Turbulence (gusts of all sizes and shapes) causes dynamic loads on various civil engineering structures, including wind turbines. The strength of the turbulence varies from place to place. Over land the turbulence is more intense than over the sea. Also the hills affect the structure of turbulence. WEng model various terrain dependent properties of turbulence.
The WAsP Engineering software package consists of three Microsoft installer files: the WAsP Engineering program, the WAsP Climate Analyst and the WAsP Map Editor. The installation files may be downloaded from the software download page. Scripts are found at the script download page. In addition, the package contains the Windfarm Assessment Tool (WAT), a set of sample data files and several demonstration projects. Documentation is included as on-line help files.
