2WindScanner.dk From new Wind Lidar Technology towards new Wind Energy Research Infrastructures…:WindScanner.dkCurrent StatusSpinnerEX 2009EU ESFRIRoad Map2010 ?MusketeerEX 2007/2008RI focusFirst CW Wind lidar 2004Scientific focusTechnical focus
3WindScanner.dk methodology is based on 3-dimensional scanning with wind lidar's to determine the instantaneous turbulence fields:Since 2005 new wind lidar's have enabled replacement of tall ( m) MET masts
34Scope for further wind LIDAR integration: Rotor PlaneUpwindBlade integrated lidarSpinner integrated lidar34
35Future research and applications: More precise yaw alignment using lidarProactive (typically +10 s) Pitch controlPro-active RPM controlWarning and mitigating of extreme loads (from gusts)More percise power-curve measurememts…Acknowledgements:The Tjæreborg “Lidar-in-spinner Experiment” was conducted as part of the Windscanner.dk RI activities 2009.Meteorology and turbine data have been provided via the Danish DAN-AERO MW project.Access to the NM80 research Turbine was granted by Vestas and Dong Energy.
