Validation of ExpertWind’s yaw misalignment detection method by comparing results to met mast wind measurements. The use case compares both the wind speed correction function as well as the final diagnosis provided.

ExpertWind’s Performance monitoring root-caused a significant change in the operational Power Curve that was created by a change in the NTF rather than its actual performance.

ExpertWind’s Yaw misalignment diagnosis was able to detect a significant yaw misalignment on multiple operating wind turbines, one example is here shown to illustrate the method and the gains in terms of AEP.

ExpertWind’s Performance monitoring was able to separate the apparent underperformance created by a faulty sensor from an underlying pitching issue hidden behind the wind speed underestimation. Once the sensor was replaced, the turbine went back to a normal operation.
