EPSILINE has successfully concluded a wind measurement campaign in partnership with the company Valemo.  EPSILINE’s YawAdvisor™, is a wind LIDAR dedicated to yaw misalignment detection on wind turbines. The YawAdvisor™ gathered data on a commercially operated wind farm in the region of Loire-Atlantic, France.


The diagnostic report has indicated a significant misalignment of the Yaw and recommends an investigation by the manufacturer and owner, to determine the cause of the misalignment. The corrective measures could include a recalibration of the traditional wind vane, or a correction of the NTF to take into account the Yaw error.


Once the corrective measures have been implemented, a second campaign is recommended to validate the correction. It would also provide an ideal comparison of the power curves before and after the correction of Yaw.
