In this study, the relationship between lidar-assisted yaw control and the measurement parameters was clarified using an experimental approach. To investigate the influence of the nacelle lidar configuration on lidar-assisted yaw control, two scan patterns and pulse-integration number settings were varied. The field tests revealed that, in most cases, the relative wind direction was reduced by the lidar-assisted control. The condition with high lidar data availability avoids the influence of noise, and the lidar-assisted control reduces the relative wind direction. These results suggest that in lidar-assisted yaw control, the management of the appropriate lidar data availability is more important than the scan pattern.
