Design and Control of a Wind Turbine Blade with an Actively Variable Twist Angle Distribution Khakpour Nejadkhaki, Hamid Hall, John Mechanical and Aerospace Engineering mechanical engineering Ph.D. The topic of this work is the design and control of a wind turbine blade with active-variable twist angle. In this approach the twist angle distribution (TAD) is controlled in relation to wind speed. This capability can improve partial-load efficiency and reduce drivetrain loads that promote fatigue. To realize these benefits it is necessary to determine the optimal TAD geometry across a range of wind speeds in the partial-load region. A physical embodiment must also be devised through a mechanical design. This step is challenging since the blade must conform to the wide range of TAD. Finally, a control framework must be implemented to adjust the TAD during operation. A concept for a flexible blade with an active TAD has been devised at part of this work. 2019-04-04T20:12:26Z 2019-04-04T20:12:26Z 2019 2019-01-18 13:23:48 Text Dissertation http://hdl.handle.net/10477/79329 eng Users of works found in University at Buffalo Institutional Repository (UBIR) are responsible for identifying and contacting the copyright owner for permission to reuse.
