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!
PO108: New concepts für wind turbine power curve testing in complex terrain
Albers Axel, Managing Director, Deutsche WindGuard Consulting GmbH
Abstract
According to current standards, wind turbine power curve testing in complex terrain requires an empirical site calibration prior to the installation of the test turbine and the application of meteorological (met) masts reaching hub height for both, the site calibration (two masts at turbine and reference position) and the power curve test (mast at reference position). As the application of hub height met masts becomes more and more impracticable, new wind measurement techniques for site calibrations and power curve tests are desirable. A breakthrough in this respect has recently been made in the frame of commercial wind turbine power curve testing in Japan: A new measurement configuration combining small met masts with a height of 60m and ground-based lidars has been implemented successfully. In this context, the uncertainty assessment of site calibrations and power curve tests as defined in IEC 61400-12-1 and IEC 61400-12-3 has been completely revised and has been formulated consistently on the basis of the rules of error propagation by Deutsche WindGuard. This new formulation has found broad acceptance within the MEASNET Power Curve Expert Team, and based on that formulation this team has worked out a detailed uncertainty assessment for site calibrations and power curve tests implementing hub height met masts with the intention to propose this method to the maintenance team of the IEC 61400-12-series. The new formulation provides new insight which properties of wind measurements at the different measurement positions are important to keep the uncertainty of the combination of site calibration and power curve test at acceptable levels. This makes the application of new wind measurement techniques for wind turbine power curve testing in complex terrain viable for the first time. Considered new measurement techniques include different combinations of met masts and ground-based lidars as well as the application of nacelle-mounted lidars.
