Pavana works according to a quality management system (DIN ISO 17025) for the planning, execution and evaluation of wind measurements. The wind measurements carried out by our team are regularly rated as good to very good by our customers.
With the help of various sensors, we determine the wind conditions at the site on measuring masts or by means of so-called remote sensing devices (LiDAR and SoDAR measuring devices), RSD for short. Here, it is important that they are representative for the planned site and allow the modeling of wind conditions for all turbine locations. A reasonable coordination between the perfectly measured site, the resources used and their costs is essential.
Pavana basically distinguishes between two different measurements:
- Estimation of wind conditions at the site with remote sensing devices (LiDAR and SoDAR measuring devices) or measuring masts. LiDAR measurements do not require a building permit and are installed in a very short time. These measurements take between three and six months.
- Long-term measurements as a basis for financing or selling wind farms: they last 12 to 24 months. The longer wind is measured, the more reliable the results. LiDAR is often used for measurements of about twelve months. For longer measurements, special measuring masts are mostly cheaper and more efficient.
We constantly monitor all wind measurements in order to optimise analysable data volumes and to prevent losses of data. To do this, we pre-analyze the data electronically on a daily basis and then check it manually.
