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!
PO070: Power on floating wind turbines: are the optimal power settings from fixed foundation adequate in a floating wind turbine?
Albert Meseguer, Lead Wind Turbine Egineer, BlueNewables
Abstract
Wind turbine controller tunning requires finding a compromise between loads and power. In the below-rated wind speed region, controllers typically maximize power by tracking an optimal Tip Speed Ratio (TSR) at a given pitch angle that is found optimal for a given aerodynamic design. The strategy is normally defined based on the Tip Speed Ratio (TSR) - Power Coefficient (CP) - Thrust Coefficient (CT) curves. The CP-CT-TSR curves are generally simulated without a foundation since it is assumed that the effect of the tower deflection is small and will not change the overall power tracking defined purely based on the aerodynamic optimality. However, the inclinations of a floating wind foundation are large enough to potentially have an impact on the power tracking strategy due to the change in inflow angle. The floater dynamics introduce another variable in the equation where the pitch of the floating foundation, or backward rotation due to the thrust force, changes the inflow angle therefore the power. As larger is the thrust, larger is the rotation and the potential loss of power due to the reduced inflow angle. This paper aims to answer a straightforward question: are the controller settings that maximum power in fixed foundation also optimal in a floating platform? In another words, optimal power is associated to optimal thrust tracking but, is it possible that operating the turbine in lower thrust settings, therefore infringing a smaller platform tilt, can compensate the reduced baseline power generation?
