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 the academic community. We look forward to seeing you there!

PO311: How to reach a tolerable risk for human on windfarms using Thunderstorms warning systems?

Stéphane Schmitt, Expert in lightning detection, METEORAGE


The aim of this study is to calculate the contribution of Thunderstorms Warning Systems (TWS) based on Lightning Locating System (LLS) in reducing the risk for workers on a Wind Turbine (WT) in the event of a thunderstorm. We used the methods described in the IEC 62305-2 (risk assessment) and IEC 61400-24 (lightning protection of wind turbines) standards, applied to the analysis of 100 wind farms spread across 11 countries in Western Europe. The main aim was to calculate the effective complementarity of a TWS with several classes of Lightning Protection Systems (LPS), and in the case of high lightning densities, to determine whether the combination of LPS and TWS made it possible to achieve a tolerable risk or not. The results obtained show that a TWS, even with a low efficiency of around 85%, reduces the total lightning risk for people by a factor of 1.5. They also show that in combination with the highest class of LPS, they can be effective even in the event of lightning strike densities of up to 6 ground strike points/year/km² (Gsp).
