- Combining SCADA data analysis and LiDAR measurements can help identify underperformance issues in wind turbines. SCADA data from one site showed turbines with dropping performance and bearing failures. A subsequent LiDAR campaign validated issues and measured power curves. - LiDAR can accurately measure power curves, yaw misalignment, and help optimize asset performance. Campaigns include installing LiDAR, monitoring performance, recommending corrections, and re-measuring. This helps reduce production losses from issues. - Data analysis and LiDAR campaigns together can identify and explain performance problems to help maximize asset output and prevent major failures. Starting with SCADA data analysis helps identify which turbines need further LiDAR investigation.

Real case : Performance analysis Sonic anemometer (FT) exchange between turbine 7 and 8 From 2015-05 to 2015-10 : Turbine 7 is the one of the best performing turbines, its p Turbine 8 is 5th performer of the site From 2015-10 to 2016-06 : Turbine 7 performance dramatically decreased Turbine 8 performance improved Turbine 7 Turbine 8 Turbine 9 Turbine 10 Turbine 11 Turbine 12
ALLA-05 and ALLA-08 temperature higher than the other since commissioning Real case : Bearing failure
ALLA-05 generator bearing failure and replacement (19/09/2015). Significant drop of the temperature while ALLA-08 remain really high. Real case : Bearing failure
• How much could have been saved : – Hypothesis : • 2 weeks before generator replacement. • 30 % capacity factor • 80 €/MWh – Actual downtime : 8 days. – Total downtime : 528 hrs. (8 days + 2 weeks) – Production loss : 475 200 kW/h – Revenue loss : €38k / £32K Real case : Bearing failure
Lidar campaign
Presentation of the measurement WPO developed a fully independent measurement system based on a two-beam nacelle LiDAR and a specially developed real time data-logger. The systems acquire the following values (1Hz sampling rate): • Lidar radial Wind Speed • Lidar relative direction • Lidar tilt • Lidar roll • Lidar status • Turbine power • Ambient temperature • Ambient pressure • Ambient humidity • Nacelle orientation 10
Lidar Power performance campaign • Campaign objectives – Accurately and independently measure the turbine power curve. – Measure the turbine misalignment : yaw error.
Lidar Power performance options • Depending on the customer needs 2 options are available: – Option 1 : yaw error estimation, correction and validation. • Installation and set up of the Lidar (≈ 1 day) ; • Daily monitoring of the system and yaw measurement trends during the first phase (≈ 15 days*) ; • Yaw correction recommendation ; • Technical recommendation ; • Daily monitoring of the system and the yaw measurement trends during the second phase (≈ 15 days*); – Option 2 : yaw error estimation, correction, validation and operational power curve before and after correction. • Installation and set up of theWind Iris Lidar (≈ 1 day) ; • Daily monitoring of the system and yaw measurement trends + operational power curve including air density correction during the first phase (≈ 30 days*) ; • Yaw correction recommendation ; • Technical recommendation ; • Daily monitoring of the system and yaw measurement trends + operational power curve including air density correction during the second phase (≈ 30 days*) ; *Time is wind condition dependant.
Campaign example of results The nacelle anemometer is showing a very poor power curve Comparison of the nacelle anemometer and the Lidar shows a very good correlation but indicates that the sonic anemometer is overestimating the wind speed. 13
Campaign example of results This could be explained by the overestimation of wind speed measured by the nacelle anemometer.The transfer function may need to be adjusted on this turbine. Discussion are engaged with the wind turbine manufacturer A power curve based on the Lidar data is better than the guaranteed power curve up to 10 m/s and then under it. 14
Conclusion • Various techniques can be used to identify and explain performance issues. These can be applied one after the other or in parallel. • WPO strongly advises to begin with a data analysis study to identify underperforming turbines. • Once the underperforming turbines are identified and if the data analysis does not provide answers then a Lidar campaign is required to further investigate.
