Special Issue Information

Dear Colleagues,

Wind turbines, both onshore and offshore, have become one of the largest machines on Earth and, consequently, one of the most challenging structures for engineers. The large size of the blades and supporting structures makes them very flexible and, therefore, sensitive to the dynamic loads induced by both wind and waves. Furthermore, the evolution of offshore installations towards deeper waters, using larger bottom-fixed foundations or floating platforms, has even further increased the importance of good dynamic performance. Therefore, the dynamic testing and monitoring of their components and of the complete structure is crucial for design validation, condition assessment during operation, and fatigue analyses, with the aim of estimating the wind turbine components’ lifetime.

In this Special Issue, we aim to collect papers reflecting the current state of the art in the dynamic testing of wind turbine components such as blades and drivetrains, and in the field dynamic testing and monitoring of these wind turbine components and their supporting structures, such as towers and onshore or offshore foundations and their connection.

Papers including a strong experimental component with in-field validations are preferred, but works based on the illustration of new data-processing strategies using numerical simulations or scaled laboratory models with high changes of application in full-scale structures may also be accepted. The description and validation of new sensing technologies applied to wind turbines’ components are very welcome.

We look forward to receiving your contributions!

To develop reliable numerical models and better interpret monitoring campaigns experimental data of wind turbines, knowing the structure operation conditions, in particular the rotor angular velocity and blades’ pitch angle, is of paramount importance, but often not known due to confidentiality restrictions, or known with low time resolution (typically 10 min average values). In this work, it is shown analytically that blades accelerations measurements contain valuable information that allow for a better characterisation of the effective rotor shaft tilt and blades cone angle for different operating conditions. It is also shown that these measurements can be used to reconstruct the time history of the rotor angular velocity and blades’ pitch angle. After presented in an analytical framework, the methodology is validated with experimental data of two full scale wind turbines. The successful reconstruction of the rotor operating conditions shows that the method presented can be used to provide further insight into the dynamics of the structure that aids monitoring data analysis and provides an alternative method to monitor the SCADA systems themselves. The paper combines quite unique experimental data collected at two operating rotors with original data processing strategies that provide very valuable information to researchers and wind turbine operators.
