Background
This work was carried out within the framework of the WEAMEC project MATILDA “MeAsurement of Turbulence Intensity by floating LiDAr”, with funding from the Pays de la Loire Region“
Abstract
- 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)
