AN INDEPENDENT MONITORING AND OPTIMIZATION TOOL
The WINDEAGLE SaaS solution, backed by nacelle-mounted laser-based IoT sensors provides valuable information and analysis for wind turbine performance diagnostics and optimization:
1. Static yaw misalignment detection :
60% of wind turbines are misaligned, some with a yaw up to 15°. This leads to a sharp drop in performance. EPSILINE WindEagle provides accurate and reliable measures of wind direction directly in front of the blades where it is relevant.
With EPSILINE WindEagle, wind farms operators can accurately correct the yaw and can lead to typically 1-3% AEP gain. In some specific cases, the improvement is up to 10%.

2. Turbulence Intensity in different wind sectors
Thanks to its short range measurement in front of the wind turbine blades, the unique laser included in EPSILINE WindEagle is able to measure precisely Turbulence Intensity for each wind turbine.
You can find more precise information on Turbulence Intensity here
The wind farm operator can thus check and optimize its curtailment strategy.
In addition, Wake steering control strategy brings 3-5% AEP gain.
Finally, Turbulence Intensity data are the most important data in Wind turbine life extension estimations by reducing uncertainty in these estimations.
