Technology.am (May 4, 2009) — Researchers have developed a technique that uses sensors and computational software to constantly monitor forces exerted on wind turbine blades.
Purdue University and Sandia National Laboratories engineers have developed a smarter wind turbine structure.
The system could help improve wind turbine reliability by providing critical real-time information to the control system to prevent catastrophic wind turbine damage from high winds.
The engineers embedded sensors called uniaxial and triaxial accelerometers inside a wind turbine blade as the blade was being built.
Such sensors could be instrumental in future turbine blades that have “control surfaces” and simple flaps like those on an airplane’s wings to change the aerodynamic characteristics of the blades for better control.
