Analysis of light detection and ranging wind speed measurements for wind turbine control

Abstract: Light detection and ranging (LIDAR) systems are able to measure the speed of incoming wind before it reaches a wind turbine rotor. These preview wind measurements can be used in feedforward control systems designed to reduce turbine structural loads. However, the degree to which such preview-based control techniques can reduce loads by reacting to turbulence depends on how accurately the incoming wind field can be measured. This study examines the accuracy of different measurement scenarios that rely on cohere… Show more

“…The LIDAR model includes the estimation of this wind component based on a line-of-sight measurement containing along-wind, horizontal, and vertical wind speeds using the assumption that the wind speeds are confined to the along-wind direction. The spatial averaging of wind speeds along the laser beam due to the LIDAR optics [7] are also modeled (see Fig. 2).…”

“…2). Additional details regarding the LIDAR measurement scenario are provided in [7]. A preview distance of d = 90 m and a scan radius of r = 44.1 m are used (resulting in a LIDAR focus distance of 100.2 m).…”

“…Lidars also have applications in wind energy resource estimation and wake characterization (Banta et al, 2013;Barthelmie et al, 2013) due to their ability to accurately and precisely measure flow structures both in front of and in the wake of a wind turbine (Simley et al, 2013;Aitken et al, 2014) and spatial variability of wind speeds over prospective wind farms .…”
