WAsP Engineering software

WAsP Engineering is a PC program for the estimation of extreme wind speeds and wind shears, wind profiles, and turbulence in complex (and simple) terrain.

 
WAsP Engineering is an umbrella of activities including measurements, analysis and modelling of those properties of the wind, which are relevant for the estimation of loads on wind turbines and other civil engineering structures situated in all types of terrain. Most of the results of these activities are unified in the computer program called WAsP Engineering. The wind properties treated in version 2.0 of this computer program are described briefly below.

Extreme wind speeds – such as the 50-year wind. If a wind turbine is well exposed on a hill, the mean wind speed and thereby the energy 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 rotor blades or other parts of the turbine. A utility program to calculate the observed extreme wind climate based on measured data is provided with version 2.0.

Wind shears and wind profiles – Strong mean wind shears (large differences of the mean wind speed over the rotor) give large fluctuating loads and consequently fatigue on wind turbine blades because the blades move through areas of varying wind speed.

Turbulence – i.e. gusts of all sizes and shapes which cause dynamic loads on various civil engineering structures, including wind turbines. The strength of the turbulence varies from place to place. Over land, turbulence is more intense than over the sea. Also hills affect the structure of turbulence. We model the various terrain-dependent properties of turbulence. A new standalone program for time series of turbulence according to IEC61400-1 ed.3 is included in 2.0.

WAsP Engineering 2.0 runs on Windows 2000, XP, Vista and 7. For further information, please visit www.waspengineering.dk.
