Abstract

Two synchronized ground-based WindScanners and a nacelle-mounted SpinnerLidar were deployed to measure wind fields in a vertical and in a crosswind plane within the induction zone of a Vestas 52 m diameter (D) test turbine located at DTU Risø Campus. First, the WindScanners are shown to be able to reproduce the vertical profiles of the horizontal mean wind speed from a reference met-mast located upwind at +2.2D. Secondly, the WindScanner measurements were used as reference for crosswind rotor plane axial wind component measurements from a two dimensional rotor plane scanning SpinnerLidar measuring at +1D. Four different algorithms are then applied to calculate and compare axial wind component derived from the SpinnerLidars multiple line-of sight wind speed measurements.
