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.
On 9 April at 17:15, we’ll also hold the main poster session and distinguish the 7 best posters of this year’s edition with our traditional Poster Awards Ceremony. Join us at the poster area to cheer and meet the laureates, and enjoy some drinks with all poster presenters!
We look forward to seeing you there!
PO050: Black blades: A comparative study into the flight behavior of birds around turbines with white and black blades
Joep Breuer, Senior Consultant Wind Energy, TNO
Abstract
Earlier studies in Norway [May 2020] have indicated that painting one of the turbine blades black can potentially reduce bird fatality rates by 70%. It is hypothesized that the effect of motion smear is reduced by having one blade painted black, therefore improving the visibility of the turbine and allowing birds to take evasive action early on. This experiment is now being repeated in RWE's windfarm in the Eemshaven (Netherlands), where besides counting bird casualties, also a wide range of other measurement techniques are employed. A 3D bird radar is installed, which together with a set of IR camera's tracks the flight behavior of birds around the regular turbine and the turbine with the black blade. Furthermore, WT-bird® systems [Wiggelinkhuizen 2006] have been installed in the blades of both turbines. The WT-bird system registers blade vibrations at various positions in the blade and by analyzing this data one can determine whether a bird impact occurred and also approximately where the impact must have happened. Additionally, also microphones have been installed in both turbines to acoustically register potential bird impacts. The combination of these different measurement techniques should provide clear insights on the effectiveness of black blades in reducing bird casualties. Analyzing the flight trajectories recorded by radar and camera will furthermore shed light on the evasive actions taken by birds in a wind farm and close to a turbine.
