  • Utilization of wind energy for power generation
    Windmill (Wind turbine Generator)
  • Objective
    Our objective is to utilize wind energy (non-conventional energy resource) for the generation of electricity.
    A small-scale windmill (wind turbine) can generate electricity if coupled with a generator and exposed to fast blowing winds.
  • Wind Power
    It deals with the conversion of wind energy into an-other usable form of energy such as electrical energy, mechanical energy (for pumping water, sailing ships, feeding water to crops) etc.
  • Wind-mill
    Windmill is a simple dynamic machine used directly to convert kinetic energy from fast blowing winds to rotational energy (mainly to turn shaft or any other assembly).
    As the wind strikes
    the blades, it causes
    the blades to
    rotate …
  • Principle of WindMill
    When the wind strikes
    blades of windmill,
    kinetic energy of wind
    is utilized by blades
    and blades rotate.
    Rotating shaft is
    connected to
    electric
    generator, which
    in turn rotates as
    the shaft does.
    Mechanical Energy from Shaft
    Since blades are
    directly connected to
    shaft, so blades
    rotate the shaft.
    Kinetic Energy from Winds
    Electrical Energy from Generator

  • Estimated Costs andProposed Materials
    Blades
    Proposed material for blades is Aluminum, PVC plastic (Aluminum foil’s price is Rs. 300 per kg, while PVC’s is 500 per kg) or Cedar wood.
    Hub
    Proposed material is ‘Steel’ or Wood (~ Rs. 200).
    Shaft
    Proposed material is ‘PVC’ (~ Rs. 150).
    Main Body
    Proposed material is ‘Aluminum sheets’ or ‘Wooden case’ (~ Rs. 500).
  • Estimated Costs andProposed Materials
    Tail
    PVC is the most suitable material (~ Rs. 150).
    Tower and Base
    PVC, Steel or Wood may be used here (Rs. 400).
    Electric motor (as generator)
    DC motor, with about 1000 rpm and 12 to 18 volts (~ Rs. 400).
    Bulb and Wires
    2 copper wires and 1 filament bulb (LEDs are also under consideration) (~Rs. 50).
    Total cost ranges from Rs. 2000 to 2500.
  • Specifications & Expectations
    We may use 3 or 4 blades for our windmill design (of about 18’’ to 24’’ length).
    We shall use dc motor as generator rated against 12 to 18 VDC.
    We hope to generate from 2 V to 5 V of potential from electric generator.
    We hope to get minimum of 100 mA of current from generator.
    If we wouldn’t be able to achieve expected results, we may increase the size of blades or rating of generator.
  • Advantages of Windmill
    Wind Energy (fuel for windmill generator) is renewable, so it will never run out.
    Windmill doesn’t produce any poisonous gases, smoke, fumes, etc. as it doesn’t involve any burning process. So, it’s clean.
    It’s a very cheap way to generate electricity from.
    Windmills have very low maintenance costs as compared to those of other power generation plants.
  • Limitations of Windmills
    Windmills cause a lot of noise, so a windmill farm may become bothersome for people living nearby.
    Installation costs for windmills are very high, and its designing requires very high technical skill and knowledge.
    Since wind is unpredictable, so we may not get electricity all the time.
    Efficiencies for these wind turbines are very low.
