Considerations for testing full-scale wind turbine nacelles with hardware-in-the-loop

Abstract: In this paper, pole placement control techniques are utilized to compensate for variations in the torsional dynamics resulting from the different boundary conditions experienced by a wind turbine nacelle when mounted on a test bench. Simulation case studies are used to understand the baseline torsional characteristics of the nacelle coupled to the test bench versus that coupled to the rotor. It was found that the frequency shifts by up to 200% and 400% for the first and second torsional modes, respectively. Th… Show more

“…The importance of WT component testing is also growing due to the advent of machine learning algorithms that rely on sensor data collected during operation to learn patterns of interest [6,7]. A common challenge among such tests is the need to identify time efficient test procedures as well as reach load levels of interest in a controllable or, at least, a predictable manner during testing [8][9][10]. This challenge is only exacerbated when performing such tests in the field as wind conditions are difficult to predict leading to a lack of controllability [1,3].…”

“…This testing platform enables full-operational testing and evaluation of sub-system interactions which become very important as the turbines become larger, especially for offshore applications. Heinold et al (2020Heinold et al ( , 2021 studied modeling requirements for real-time implementation and proposed control techniques necessary to compensate for differences between the virtual and real drivetrains in the HIL setup. Another aspect for successful implementation of HIL platform is the capability of the test bench to apply dynamic loads with enough bandwidth and understanding of the acceptable load tracking performance.…”
