Study on Optimization of Control Mechanism in Vertical Axis Wind Turbine


Objective-This paper describes an attempt to streamline the execution of the Vertical Axis Wind Turbines (VAWT) utilizing dynamic sharp edge pitch control. Methods/analysis- Aerodynamic model is chosen based on the surface profile and NACA 4-digit series was found to be the most suitable category under which NACA 0018 aerofoil design parameters have been chosen for the VAWT blade design, based on the previous research. The outline of wind turbine picked here is an H-sort Darrieus VAWT which deals with the lift drive of the wind. Findings- Active Pitch controlled VAWT with individual pitch control of each blade along with vertical roller bearings in the system is done to obtainmaximum coefficient of power harnessed from the wind turbine setup and increase the efficiency by 12.5%. Applications: The proposed design system is suitable for low wind speed areas which turbine is installed at lower heights.
