Use of remote sensing for performance optimization of wind farms

The main purpose of the project is to gain experience on the use of remote sensing technology in the post construction phase. The turbine performances have been evaluated using a nacelle mounted lidar at four different wind turbines at two Swedish wind farms.  

The nacelle mounted lidar has been useful in the evaluation of the turbine yaw alignment relative to the wind direction in short measurement periods. No major yaw errors have been found at the observed wind turbines within this research project. There are large discrepancies found between operational power curves and commercial power curves. Moreover, large discrepancies have also been found in comparison of nacelle anemometry measurements with nacelle mounted lidar measurements.

Main challenge for all the measurement campaigns in this research project has been the issues related to the sites terrain complexity, in addition to fact that chosen sites being located at forested and cold climate environments. Relevant topics have been addresses as future work with the use of newly developed remote sensing techniques with the investigation of uncertainty sources.
