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!
PO212: Impact on wind turbines lifetime due to high presence of shear values that exceeds standard limit
Eliana CORNALINO, Wind Energy Specialist, UTE
Abstract
The aim of this work is to analyze and quantify the effect on wind turbine lifetime of the vertical wind profile characteristic of Uruguay and the region. Observed wind shear at 100 m of height in this region presents shear values significantly larger than the value established by the IEC 61400 standard for wind turbine design. This is due to the high frequency of strongly stable atmospheric states which are recorded at night. The difference between the normative and real values can have a direct impact on the durability of wind turbines. A more aggressive wind profile generates higher stresses on critical components such as the rotor, blades, and tower, potentially shortening the estimated lifespan due to fatigue. Uruguay has a total of 1,516 MW of installed wind power, which accounts for nearly 40% of the country's annual electricity supply. Almost all of the installed wind turbines have been in operation for between 8 and 10 years, so it is expected that in less than a decade all wind farms will begin to reach the end of their expected lifetime. In this context, the present study is developed towards estimating the potential impact that the mentioned wind resource particularities, could have on the lifetime of our current wind power installed capacity. are also made about the impact of the characteristic wind profiles of this region on larger wind turbines, considering that the following stages of our wind expansion will follow the global trend in this regard.
