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 will give delegates an opportunity 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 industry and the academic community.
PO118: Suitability of Ground LiDAR for the performance of Power Curve Test (PCT) in complex terrain including Site Calibration (SC) by combination of Ground LiDAR at the Ref_pos and hub height met mast at the WTG_pos.
Ana Barreno, Wind Turbine Test Engineer, Barlovento Applus+
Abstract
The analysis compares the results of one Power Curve test (PCT) in a highly complex terrain, requiring a previous Site Calibration (SC), obtained through the conventional methodology based on met masts and through Ground LiDAR. For that purpose, one Ground LiDAR was located at the Ref_pos in parallel with the conventional hub height met mast both during the SC phase and also during the PC phase. This approach is based on the principle that most relevant during the Site Calibration phase is the accurate characterization of the wind speed at the future WTG location. This can be achieved by using a conventional anemometry hub height met masts at that WTG location. However, the measurements at the Ref_pos. do not need to be so precise but need to be consistent throughout the entire measurement period from the Site Calibration to the Power Curve measurement, and traceable from the Ref_pos to the WTG_pos. This is supported by the fact that those measurements in that Ref_pos. are corrected via the Site Calibration correction factors, and thus the possible errors of the LiDAR devices in complex terrain (measurements based on the assumption of homogenous flow conditions) are corrected and cancellated, being at the same time, consistent between the two phases provided that some basic measures are taken (same model of LiDAR; same location and alignment,..) . This alternative approach: * represents significant advantages in terms of feasibility and cost (the LiDAR unit can be removed during the period between the two phases for other services). * is currently under discussion within the MT-12 of the IEC standard, with a view to be included as an alternative procedure in the next edition of the IEC 61400-12-X standard
