Abstract
Growing interest in distributed renewable generation has increased demand for vertical axis wind systems that operate in variable wind directions without complex yaw mechanisms. An enhanced large-size VAWT with 24V output offers practical power levels for battery charging and laboratory demonstration.
This project develops an Enhanced Vertical Windmill System featuring a multi-blade vertical rotor, sturdy tower, 24V permanent-magnet generator, charge controller and battery bank. Key subsystems include rotor and hub fabrication, structural support, generator coupling and power conditioning. The unit demonstrates wind energy conversion at a scale suitable for academic evaluation and outdoor testing.
It is an excellent final-year project for Mechanical, Electrical, Mechatronics and Renewable Energy students, combining large-scale fabrication, aerodynamics and power electronics.
