AN INDEPENDENT MONITORING AND OPTIMIZATION TOOL

The nacelle-mounted wind LiDAR Advisor provides valuable information that enables multiple types of analysis of wind turbine performance and optimization:

1. Yaw misalignment detection, leading to increased performance and decreased stress loads :

• Average Static Yaw misalignment
• Yaw behaviour at different wind speeds
• Yaw behaviour in different wind sectors.

2. Turbulence Intensity in different wind sectors

Thanks to its short range measurement in front of the wind turbine blades, the EPSILINE Advisor is the unique lidar which is able to measure precisely Turbulence Intensity for each wind turbine.

The wind farm operator can thus check and optimize its curtailment strategy.

3. Comparative performance analysis using Operational Power Curves

• Power Curve analysis to compare performance before and after improvements on the wind turbine e.g. yaw or pitch modifications, blade extensions, upgrades, retrofitting, etc

• Power Curve for Long term monitoring of performance and evolution over time.

4. Free-stream equivalent Power Curve. Comparable with site assessment data or power curve verification.

5. Gust detection

Thanks to its 2s wind speed measurements, the lidar-based sensor suite is able to detect rapid changes in wind speed or gusts.

6. Usable data for Wind turbine life extension estimations and reducing uncertainty in these estimations.
