Time-response of a wind turbine: role of kinematics

Abstract : During the course of a recent research project, we carried out a measurement campaign in the south-east of France, near Narbonne. There, we measured the time-varying RCS of many wind turbines in operation, and gathered data for several manufacturers as well as in different environmental conditions. Thus, we did assemble a large database of wind turbine signatures (S-band). Due to their very large electrical size as well as their rotation, wind turbines RCS varies greatly, by several tens of dBs, over a small angular range or time interval. Therefore, to understand the origin of the main contributions to the RCS for a given measurement, it is essential to have a good knowledge of wind turbine kinematics. To make the most of our database, we thus gathered extensive SCADA data, with the help of wind turbines operators, to help correlate signatures with kinematics. In this contribution, we share the lessons learned from the collected SCADA data, highlight the main factors underpinning wind turbines RCS, analyze the possible shortcomings of our interpretation, and discuss possible avenues for future comparison with simulations.
