    1. 1. Utilization of wind energy for power generation<br />Windmill (Wind turbine Generator)<br />
    2. 2. Objective<br />Our objective is to utilize wind energy (non-conventional energy resource) for the generation of electricity.<br />A small-scale windmill (wind turbine) can generate electricity if coupled with a generator and exposed to fast blowing winds.<br />
    3. 3. Wind Power<br />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.<br />
    4. 4. Wind-mill<br />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).<br />As the wind strikes<br />the blades, it causes<br />the blades to<br />rotate …<br />
    5. 5. Principle of WindMill<br />When the wind strikes<br />blades of windmill,<br />kinetic energy of wind<br />is utilized by blades<br />and blades rotate.<br />Rotating shaft is<br />connected to<br />electric<br />generator, which<br />in turn rotates as<br />the shaft does.<br />Mechanical Energy from Shaft<br />Since blades are<br />directly connected to<br />shaft, so blades<br />rotate the shaft.<br />Kinetic Energy from Winds<br />Electrical Energy from Generator<br />

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