Abstract
The world first field test of plasma aerodynamic controlled wind turbine was conducted. Mie University’s 30kW horizontal axis wind turbine with a 10m diameter and 13.4m in hub height was used. Dielectric barrier discharge electrodes of 4m in length were installed on the surface of the leading edge of each blade. Alternating voltage of 5.5kV in pulse modulation mode was applied to each electrode from inverters under the nacelle through slip rings. Atmospheric pressure plasma was successfully generated on the electrodes on actual rotating blade. In the case of 60rpm fixed rotational speed, a significant enhancement in rotor torque was confirmed in high wind speed region. Averaged power generation was also increased by the plasma effect.
