AN INDEPENDENT MONITORING AND OPTIMIZATION TOOL
The nacelle-mounted wind LiDAR YawAdvisor™ provides valuable information that enables multiple types of analysis of wind turbine performance and optimisation:
1. Comparative performance analysis using Operational Power Curves (OPC)
- 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 analysis to compare wind turbines in a single wind farm, to detect above and below average performance.
- Power Curve for Long term monitoring of performance and evolution over time.
2. Yaw misalignment detection, leading to increased performance and decreased stress loads : Average Static Yaw, Yaw behaviour at different wind speeds.
3. Sector analysis to determine yaw behaviour and Turbulence Intensity in different wind sectors.
4. Usable data for Wind turbine life extension estimations and reducing uncertainty in these estimations.
5. Free-stream equivalent Power Curve. Comparable with site assessment data or power curve verification.
Technology
The traditional measuring instruments on a wind turbine (anemometer and wind vain) are used to control the wind turbine. In particular, the wind vain allows the wind turbines to rotate and follow the wind direction.
However these measurements, down wind from the blades are subjected to turbulence and will be inherently erroneous, despite sophisticated software to correct them. Consequently wind turbines will not be perfectly aligned with the oncoming wind direction, causing Yaw misalignment, lost performance and additional stress loads on the wind turbine.
The solution is to install on the top of the nacelle roof a LiDAR (laser anemometer) and measure in front of the blades. Consequently the Lidar provides precise and continuous measurements of wind speed and direction.
