Windarea.First automated location analysis for small wind potentials.
We find the perfect location for your small wind turbine.
Determination of the optimal position – solution of the location problem.
The biggest challenge in the field of small wind power is the choice of a suitable location for the turbine.
The correct positioning is indispensable for the economic efficiency, as the yield from wind power increases in third power depending on the speed of winds.
Wind-area is the first tool to solve the problem of location.
The analysis at building and terrain level allows the precise determination of local wind conditions. In this way, it is shown in detail at which point turbulences occur and which location is optimally suited, taking into consideration any obstacle.
Wind currents and their behaviour in the area of obstacles can be accurately modelled by wind-area and thus determine the most economical locations for small wind turbines. Expensive test measurements can be limited by the modelling of wind-area to the locations, which are shown to have a particularly high wind speed in the simulation.
Wind-area is the first potential analysis specialized for small wind turbines on the basis of 3D-geodata. The method is based on the grading of high-resolution laser scanning data with regional wind data through tools of air flow theory.
The result of wind-area is a graphical information, which is the wind speed in high resolution in certain altitudes, e.g. From 1 m to 10 m above the surface of the terrain, obstacles or buildings. The wind potential maps show the exact currents on building roofs and other areas with high wind speeds.
As a data basis for the modeling of the 3D-surface, high-resolution data of the National Office for Geoinformation and Land development as well as wind measurement data of the National Institute for Environment, Measurements & Nature Conservation are used. Planning data, for example from a building application, can also be used for the design of the 3D-model.
Wind conditions in the planned area are strongly influenced by the ground roughness, as well as by orographic effects (the terrain structure). The location is particularly important: the difference in altitude of the area, the prevailing wind directions at the planning site, which are represented in a separate graphic as orography. On the basis of frequency distribution, these leading directions are chosen in the simulation (main wind direction) and the average wind velocity over the year is taken into account in 10m height above ground.
Results and objective of the analysis.
A brief description of the circumstances influencing a maximum wind speed at a detailed building site. The expected average annual wind speed is indicated in the most suitable position. In addition, the analysis contains a height profile of the wind speeds, as well as pictorial representations of the wind conditions at each part of the building. In addition, you will receive videos that show the wind flow conditions.
Which building or which part of the building is best suited for small wind turbines?
An example from an analysis:
“It is advisable to install small wind turbines up to 3m above object height depending on the type of turbine. In the vertical section, it can be clearly seen that the highest wind speeds can be found directly at the rear part of the roof ridge (northern part) due to the local turbulence. ”
We are happy to provide you with an example analysis.
