Abstract

This report is a project report on the EUDP research project SpinnerFarm. The objectives of the project were to improve software and hardware on the spinner anemometer concept and to demonstrate improvement of wind farm performance by opitmized yaw control. The hardware was improved by a more powerful microprocessor and heating was added to the sonic sensor arms plus a range of smaller redesigns. Software was revised with an improved internal calibration procedure. The improved system was tested on a 2MW wind turbine at Tjæreborg wind farm. Measurements on this turbine includes calibration of K factors, determination of induction in center of rotor, measurements of yaw error, inflow angles and turbulence intensity, and measurements of power performance, comparing the spinner anemometer with the mast cup anemometer and the nacelle anemometer. A statistic of yaw error measurements were made in the Vedersø Kær wind farm on nine wind turbines. Finally, estimates of potential power performance gain on the wind farm and the test wind turbine by optimized yaw error measurements was made.
