Field Testing of Feedforward Collective Pitch Control on the CART2 Using a Nacelle-Based Lidar Scanner
This work presents the first results from a field test to proof the concept of LIDAR assisted collective pitch control using a scanning LIDAR device installed on the nacelle of a research turbine. The purpose of the campaign was to show that a reduction of rotor speed variation is feasible with a feedforward update without changing the feedback controller. Although only a small amount of data c...
متن کاملField Testing of Flatness-Based Feedforward Control on the CART2
Nacelle-based lidar systems are offering a good opportunity for new wind turbine control strategies, since inflowing wind information can be used in the controller. The benefits of lidar-assisted collective pitch feedforward control have been presented over the last years and was successfully demonstrated in several field testings, latest results see [1, 2]. This controller yields an improved r...
متن کاملNacelle LiDAR online wind field reconstruction applied to feedforward pitch control
This paper presents innovative filtering and reconstruction techniques of nacelle LiDAR data, and exploitation of obtained wind anticipation capabilities for wind turbine control strategy. The implemented algorithms are applied under industrial constraints, on a MAIA EOLIS wind turbine, equipped with a LEOSPHERE 5-beams pulsed LiDAR, during experimental campaigns of SMARTEOLE collaborative proj...
متن کاملLoad Analysis of Look-ahead Collective Pitch Control Using Lidar
Nacelle based LIDAR (Light detection and ranging) systems provide preview information of wind disturbances at various distances in front of a wind turbine. Preliminary work towards this objective [1] has shown that the predictive knowledge of the rotor effective wind speed can be used to improve the speed regulation by a predictive feedforward update to the collective pitch feedback controller,...
متن کاملFlatness-based Feedforward Control of Wind Turbines Using Lidar
Current lidar technology is offering a promising opportunity to take a fresh look at wind turbine control. This work evaluates a flatness-based feedforward approach, that allows to calculate the control action based on trajectories of the rotor speed and tower motion using wind measurements. The trajectories are planned online considering actuator constrains to regulate the rotor speed and mini...
