Task 32 Workshop 10: Turbulence Intensity Measurements with LiDARs – Applications to Loads Verification and Site Suitability

Date: 20. – 21. September 2018

Venue: Ørsted, Gentofte (5 km North of Copenhagen), Denmark

Workshop leader: Ameya Sathe (Ørsted)

Organization team: Eric Simley (NREL), Detlef Stein (Multiversum), David Schlipf (HS Flensburg)

Background to the workshop

Organized by Ørsted and held at their offices in Gentofte, Denmark, this two-day workshop considered how lidar-derived TI could be used for load verification and site suitability. Different methods for estimating TI from lidar measurements were presented by wind turbine manufacturers, lidar suppliers, researchers, and consultants. Barriers to the widespread application of these methods for wind turbine load verification and site suitability studies were identified and potential solutions were discussed.
