Research on wind field visualization based on UAV wind measurement method

Abstract

This study introduces an efficient and precise method for gathering atmospheric wind field data in specific regions, utilizing unmanned aerial vehicles (UAVs) equipped with anemometers. We conducted outdoor wind field measurements over complex terrains using a six-rotor UAV equipped with an ultrasonic anemometer. The results obtained include a vertical wind field profile at the center of the measured site, along with two planar wind field profiles at 20 m and 40 m heights. The analysis reveals a remarkably high fitting accuracy for the wind profile and turbulence intensity results obtained. Furthermore, the planar wind field data partially demonstrates the impact of terrain on the upper-level wind field within the surveyed area. Lastly, we established a three-dimensional wind field visualization approach using the data gathered through the UAV wind measurement method, implementing Kriging interpolation. This study’s outcomes offer novel insights and methodologies for local wind field measurement, micro-siting in wind farms, and the creation of visualized wind fields.
