Flatness-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...
متن کاملLidar Assisted Control of Wind Turbines
LIDAR systems are able to provide preview information of wind speed, direction and shears at various distances in front of the wind turbines. This technology paves the way for new control concepts such as feedforward control and model predictive control to increase the energy production and to reduce loads of wind turbines. This paper describes how the necessary information can be obtained from...
متن کاملDFIG Based Wind Turbines Behavior Improvement during Wind Variations using Fractional Order Control Systems
This paper is concerned with behavior analysis and improvement of wind turbines with Doubly Fed Induction Generator (DFIG) when using a new fractional-order control strategy during wind variations. A doubly fed induction generator, two types of variable frequency power electronic converters and two input wind waveforms are considered. A fractional-order control strategy is proposed for the wind...
متن کاملModel of the Correlation between Lidar Systems and Wind Turbines for Lidar Assisted Control
Investigations for lidar assisted control to optimize the energy yield and to reduce loads of wind turbines increased significantly in recent years. For this kind of control it is crucial to know the correlation between the rotor effective wind speed and the wind preview provided by a nacelle or spinner based lidar system. If on the one side the assumed correlation is overestimated, the uncorre...
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...
