Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics and provide an opportunity for delegates to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please, join us at the conference and take advantage of this opportunity to learn and engage with your peers in the academic community. We look forward to seeing you there!
PO161: A highly flexible control software for adaptive and synchronized long-range multi-lidar measurements
Tobias Klaas-Witt, Research staff, Fraunhofer Institut for Energy Economics and Energy System Technology (IEE)
Abstract
Long-range scanning lidars in dual- or multi-lidar configurations offer the possibility for new and efficient measurement setups for multiple applications in onshore and offshore wind energy. Besides the application of e.g. plane-position indicator (PPI) scans that enable to measure and visualize the two-dimension wind flow field, especially synchronized line-of-sight (LOS) scans allow to derive highly accurate wind speeds and directions at multiple positions and heights in a planned wind farm. By the application of advanced methods it is also possible to significantly improve turbulence measurements based on Doppler lidar measurements. However, so far, there is now standard procedure or tool to make advantage of the full potential of multi-lidar measurements. The process of installation and configuration requires a lot of resources. In addition, continuous monitoring and quality control of running measurement campaigns is time consuming. Combining multiple scanning lidars also creates a huge dataset that needs to be analysed and combined to generate the final wind speed and wind direction time series. This makes multi-lidar measurements error-prone and often generates a lack of repeatability. In addition, the synchronisation between multiple systems, which is desirable for e.g. turbulence measurements, cannot be achieved without a central control-software. This poster presents Fraunhofer IEEs software to perform synchronised multi- and scanning lidar measurements with a user-friendly GUI. It has been developed in the course of several research projects about scanning lidar measurements for wind energy applications. The software is currently designed for Vaisalas lidar API but can be adapted to other devices as well.
