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 provide an opportunity for delegates 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!
PO226: Online application of a linear aero-hydro-elastic model for virtual monitoring of an operational wind turbine
Marco Turrini, Junior Scientist, TNO - Netherlands Organisation for Applied Scientific Research
Abstract
Monitoring the state of wind turbines during their operational life is key to good asset management. While monitoring based on measurements is reliable, it can also be expensive, especially when (distributed) load measurements are required. For this reason, standard operational measurements on wind turbines often do not include these extensive sensor setups. However, real-time numerical simulations of the actual operation of physical assets (a 'digital twin') can be used to provide these additional (virtual) measurements. In addition, the information from the Digital Twin (DT) can be used to intervene in O&M decision-making, system control, and more Using real-time aero-hydro-elastic simulation for wind turbine monitoring introduces several challenges, such as how to handle the unknown disturbance from the wind, how to align the states that are driven/controlled and how to accommodate the non-linear behaviour of the wind turbine model. To tackle these issues, this work presents the development of an online wind turbine digital twin based on a Kalman filter augmented state space Linear Time-Invariant (LTI) wind turbine model. The DT tool was tested both offline and online[1], simulating and monitoring a fully functional test wind turbine. It demonstrated the possibility of fast virtual measurements gathering and processing similarly to physical measurements of the wind turbine of interest. [1] Hereafter, online and real-time are considered interchangeable: a speed of virtual measurement generation (simulation) matching with the speed of operation (and monitoring) of the physical system.
