Wind turbine wake tracking and its correlations with wind turbine monitoring sensors. Preliminary results

Within the frame of the French project ANR SMARTEOLE, a 6-month measurement campaign has been set-up in the north of France to study the wake behaviour of two wind turbines, with an original set-up using: one ground based scanning LIght Detection And Ranging system (LIDAR), 2 nacelle-mounted LIDARs and a nacelle-embedded 2-axis inclinometer. The present paper will give first insight into the results and describe the different post-processing strategies used to prepare the data to be cross-correlated; within the project the final objective is to characterise the influence of the large-scale atmospheric turbulent eddies on the overall wind turbine nacelle displacement and wind turbine wake behaviour.
