Research on Individual Pitch Control Based on Inflow Angle

2011 International Conference on Control, Automation and Systems Engineering (CASE), 2011
The pitch-controlled techniques for large scale wind turbine are deeply analyzed in this paper. Based on wind turbine aerodynamics, the basic law of pitch control is deduced, and a design of hydraulic pressure system of individual pitch control is introduced. The correlative theoretical calculation results are also analyzed.

Periodic wind disturbance rejection using robust individual pitch control

Smart Materials and Nondestructive Evaluation for Energy Systems IV, 2018
A robust individual pitch control strategy is presented to deal with periodic load disturbances on wind turbines under operating point variation. The asymmetric loads are mainly caused by the tower shadow and wind shear effects. Multi-blade coordinate (MBC) transformation is utilized to model the turbine dynamics under various operating points.

Performance Similarities Between Individual Pitch Control Strategies

2018
The use of blade individual pitch control (IPC) offers a means of reducing the harmful turbine structural loads that arise from the uneven and unsteady forcing from the oncoming wind. In recent years two different and competing IPC techniques have emerged that are characterised by the specific loads that they are primarily designed to attenuate. In the

Reduction of wind turbine tower oscillations based on individual pitch control

2012 20th Mediterranean Conference on Control & Automation (MED), 2012
The use of wind power has been increasing rapidly over the last few decades and according to all predictions this trend is likely to continue. At the same time, the need for better cost effectiveness of wind power plants has stimulated growth in wind turbines' size and rated power, thus making wind turbine structure very flexible. Therefore an advanced

Torque smoothing control of wind turbine generator system using individual pitch control

Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012
The uneven force of the wind rotor on the rotation plane causes the torque fluctuation of wind rotor and unbalanced load because of wind shear, tower shadow turbulence and other factors. In this paper the dynamic aerodynamic model of three-blade wind turbine applied to individual pitch control is built using the blade element theory, and the wind rotor

Experimental analysis of yaw by individual pitch control

2020
This study is a collaboration between Technische Universität München (TUM) and University of Perugia and consists in analyzing, through wind tunnel tests, the mechanical aspects of yaw by Individual Pitch Control (IPC) on a wind turbine scaled model. A total of about 60 tests have been executed in different conditions in order to assess a comparison ...

Machine Learning Control for Floating Offshore Wind Turbine Individual Blade Pitch Control

2020 American Control Conference (ACC), 2020
The cost of energy from current floating offshore wind turbines (FOWTs) are not economical due to inefficiencies and maintenance costs, leaving significant renewable energy resources untapped. Co-designing lighter less expensive FOWTs with individual pitch control (IPC) of each blade could increase efficiencies, decreases costs, and make offshore wind ...
