Monitoring campaign in an onshore wind farm: Installation description and preliminary results

Abstract

In the context of the WindFarmSHM project a quite extensive experimental campaign is being performed in Tocha wind farm, an onshore wind farm located in Portugal. This includes the instrumentation of at least two wind turbines aiming the development, validation and optimization of monitoring strategies at the level of the wind farm for damage detection and fatigue analysis, using the response to operation loads measured by strain gages and accelerometers distributed in the tower and blades. The paper presents the experimental layout, introduces the processing tools under development and shows some initial results. At this preliminary stage, it will be evaluated the ability of the different monitoring components to track the modal parameters of the system composed by the tower and the rotor.
