This report has been written as part of the DTU Wind Energy V52-CCA cross-departmental measurement campaign in the autumn of 2018. and it describes the experimental details concerning the Shortrange Windscanner measurements performed as part of the campaign. The goal of the measurements is to investigate the wake turbulence characteristics of the Vestas V52 test turbine located at DTU Risø campus.
Because scanning the full wake cross-section would be quite time consuming and would thus impede the aim of measuring the turbulence it was decided to instead scan along two orthogonal lines stretching about 120 m in the horizontal and 90 m in the vertical direction and crossing approximately 110 m East of the turbine. This meant that a scan rate for the full trajectory of about 1 Hz could be achieved while measuring 322 points along the path. As an extra feature an additional scan trajectory was designed with
the purpose of capturing the wake from the Babylon or multirotor turbine in case of southwesterly winds. The raw measurement data were converted into three orthogonal wind velocity components (u,v,w) together with associated spatial and temporal coordinates and stored in a DTU Wind Energy database.
The report is organised in the following way that. First the Shortrange Windscanner system is presented and the most important aspects of it explained. Then the measurement setup geometry is described together with the scanning trajectories optimised for fast scanning of the turbine wake. Finally, the processing of the most important measurement outputs is described together with a description of how and where they can be accessed
