Abstract
Climate concerns and the need for distributed renewable generation have increased interest in small wind energy systems. A mini windmill offers a practical, low-cost platform to study wind energy conversion, rotor design and electrical power generation at student level.
This project develops a Mini Windmill Power Generation system that harnesses wind through a multi-blade rotor coupled to a permanent-magnet DC generator. Key subsystems include the fabricated rotor and tower, generator mounting, rectification/charge control and battery storage. The unit demonstrates core concepts of renewable energy engineering suitable for academic evaluation.
It is an excellent final-year project for Mechanical, Electrical, Mechatronics and Renewable Energy students, combining fabrication, aerodynamics and power electronics.
