Small Vertical-Axis Wind Turbine with Charge Controller

Approx. component budget: Rs. 6,000 - 12,000

Objective

Build and test a small wind turbine, and plot power against wind speed.

What you will build

A small Savonius or H-Darrieus rotor with a permanent-magnet generator, a rectifier and a charge controller that charges a battery and logs power.

Results you can expect

• Power curve (W vs m/s) with an anemometer
• Cut-in speed
• Power coefficient estimate
• Battery charging record
• And a comparison of two blade designs

What you will learn

Wind energy basics, generator characteristics, rectification and charge control.

Tools and notes

PMDC or hub generator, anemometer, rectifier, buck-boost charge controller, Arduino. Test in open areas with a safe guard around the rotor and a brake.

Resume points from this project

• Built and tested Small Vertical-Axis Wind Turbine with Charge Controller; objective: build and test a small wind turbine, and plot power against wind speed.
• Measured and analysed power curve (W vs m/s) with an anemometer and cut-in speed; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
