In power performance testing, it has been demonstrated that the effects of wind speed and direction variations over the rotor disk can no longer be neglected for large wind turbines . A new generation of commercial nacelle-based lidars is now available, offering wind profiling capabilities. Developing standard procedures for power curves using lidars requires assessing lidars measurement uncertainty that is provided by a calibration. Based on the calibration results from two lidars, the Avent 5-beam Demonstrator and the Zephir Dual Mode (ZDM), we present in this paper a generic methodology to calibrate profiling nacelle lidars.
