ABSTRACT When extracting energy from the wind using horizontal axis turbines, ability to align rotor with mean direction is crucial. In previous work, a method for estimating yaw error based on measurements spinner mounted light detection and ranging (LIDAR) device was developed tested. this study, simulation parameter space extended include higher levels of turbulence intensity. Furthermore, applied experimental data compared met‐mast corrected calibration that not discovered during work. Finally, shortcomings LIDAR estimation are discussed. The study shows method, can be estimated precision few degrees, even in highly turbulent flows. Applying reveals an average approximately 9° period 2 h, good correlation seen between LIDAR‐based estimates data. final discussion suggests number challenges when complex flow.
