Control of Large Wind Turbines

Please attend the Lockheed-Martin sponsored ASSET seminar in Thornton Hall, Room E316, the University of Virginia, at 3:00 PM on Friday September 14, 2012.

Prof. Mark Balas, “Control of Large Wind Turbines: It Doesn’t Take a Weatherman to Know Which Way the Wind Blows”

Abstract: The next generation of utility-scale wind turbines will be larger and more flexible than earlier designs to promote greater energy capture and reduce the cost of energy.  It is here that the implementation of active feedback control is crucial to meet design objectives.  Not only must there be power regulation or optimization but also load mitigation to extend the life of the turbine.  Wind turbine dynamics modeling for active control is composed of four principal parts: (1) Aerodynamics and Inflow Behavior (2) Structural Dynamics (3) Feedback Control Algorithms and (4) Power Electronics.  Active control is a relatively new technology for wind turbines.  Basic control theory used in this talk is linear time-invariant and periodic control using disturbance accommodation, but with a strong connection to the aerodynamics and structural dynamics of wind turbines.  This talk will be a non-specialist’s tutorial on control of large wind turbines but will also introduce our adaptive control work in this research area.  I hope, when we are done, no one will ever be able to “kick sand in your face” about utility-sized wind turbine control.

This seminar is a great opportunity to broaden your base of knowledge, which can help spark new ideas in your own research, and could be invaluable in job interviews.  The Q&A based Fireside Chat session will be useful to learn best-current practices. Plan some questions for this distinguished faculty member.
