Components of wind measurement systems
The better the quality of the components of a measuring system are, the more accurate are the results of the wind site assessment.
The wind measurement system
- has to work independent from the grid,
- has to be weather-resistant and
- must meet the requirements for flight safety.
Even in very remote areas the measurement system has to reliably transfer measurement data to the wind consultant.
A measurement system has to meet the local requirements of climate and landscape.
In general, the wind measurement system includes the following components:
- Met mast
There are two types of masts in use:
- Lattice masts
- Telescope masts
- Steel cabinet
The steel cabinet containing
- Data logger
- Communication system
- Components for the power supply and
- All additional system components
is mounted typically at a height of approx. 6 m to prevent from thieves or vandalism, while allowing maintenance and service access.
Additional system components can be:
Remote Sensing Divices as addition
In addition to a met mast, remote sensing devices like LiDAR and SoDAR can be used to increase the number of available measurement data in the region. If LiDAR or SoDAR devices should be used for wind site assessment, the requirements described in the latest IEC 61400-12-1 and the German TR6 guideline should be considered.
