Wind Turbine Performance
Performance Improvement and Acoustic Level Attenuation.
This technology advantages include reduced blade weight & turbine noise, Increased Airfoil Efficiency & Energy Capture and Gust force mitigation.
Description: We have pioneered the development of plasma actuators for aerodynamic control. Patented technology for the application of plasma-enhanced flow control of wind turbines will translate into increased capacity, normalized output, decreased structure weight, and decreased cost. A proof of concept of plasma-based aerodynamic control on wind turbine blades was demonstrated in 2008 and verified gust force alleviation for the full range of fullscale wind turbine speeds while increasing energy capture. Technology A single dielectric barrier aerodynamic plasma actuator apparatus based on the dielectric barrier discharge phenomenon for application to aerodynamic uses in drag reduction, stall elimination, and airfoil efficiency improvement and optimization. Non-uniform in time and space, partially ionized gasses are generated by one or more electrode pairs each having one electrically encapsulated electrode and one air stream exposed electrode with energization by a high-voltage alternating current waveform. Advantages • Increased Airfoil Efficiency & Energy Capture • Lower Cut-in & higher Cut-out speeds • Reduced blade weight & turbine noise • Gust force mitigation • Normalized output
