Pavana is accredited for the planning, execution and evaluation of wind measurements. The wind measurements carried out by the PAVANA team have gained a strong reputation over the years and are regularly rated as good to very good.
Using a range of sensors, wind conditions at the site are measured on met masts or by remote sensing devices (RSD). It is important that they are representative of the proposed site and enable the wind conditions to be modelled for all of the turbine locations. Proper coordination between the accurately surveyed site, the resources allocated and their costs is essential.
Pavana distinguishes between two different sets of measurements:
- Assessment of the wind conditions at a site using remote sensing devices (RSD) or met masts. LiDAR measurements are relatively easy to implement as the equipment does not require a planning permission and can be installed quickly. These measurements take between three and six months.
- Long-term measurements as the basis for financing or marketing of wind farms: these take 12 to 24 months. The longer the wind is measured, the more reliable the results. LiDAR devices are often used for measurements of around 12 months. For longer measurements, special met masts are generally more cost-effective and efficient.
We constantly monitor all wind measurements in order to optimise analysable data volumes and to prevent losses of data. For this reason, the data is pre-analysed electronically on a daily basis and then checked manually.
