Contexte
Cette publication a été menée dans le cadre de WEAMEC et du projet MATILDA sur la « mesure de l’intensité de turbulence par un LiDAR flottant », avec le financement de la région Pays de la Loire.
Résumé de la publication
- The mean overestimation of the Floating WindCube v2 Turbulence Intensity measurements : ~0.03 (at Fécamp, buoy WINDSEA_02)
- No meteoceanic conditions can ensure a proper TI measurement from the FLS : need for a correction of the motion induced TI
- We have created a model that quickly evaluates the 10min TI error induced by the motion of the buoy : inputs: the six degrees of freedom of a IMU and the 10min mean wind speed data from the floating lidar
- Using the model drastically reduces the TI measurement error of the floating WindCube v2 : It increases the coefficient of determination and reduces the mean error to ~0.005 compared to the ground lidar (could be improved with clever spike removing methods)
