Electricity Production By Wind Energy Gaurav Anand ID : 05JHADAVKN0404

Electricity is energy transported by the motion of electrons Electricity is energy transported by the motion of electrons **We do not make electricity, we CONVERT other energy sources into electrical energy** **We do not make electricity, we CONVERT other energy sources into electrical energy**

Faraday Effect Basic Concepts Voltage – V – Potential to Move Charge (volts) Current – I – Charge Movement (amperes or amps) Resistance – R – V = IxR (R in =ohms) Power – P = IxV = I 2 xR (watt)

Small (  10 kW) Homes Farms Remote Applications (e.g. water pumping, telecom sites, icemaking) Large (250 kW - 2+MW) Central Station Wind Farms Distributed Power Intermediate ( kW) Village Power Hybrid Systems Distributed Power

Nacelle 56 tons Tower 3 sections Workers Blade 112’ long

 450’ base to blade  Each blade 112’  Span greater than 747  163+ tons total  Foundation 20+ feet deep  Rated at 1.5 – 5 megawatt  Supply at least 350 homes

 No other factor is more important to the amount of power available in the wind than the speed of the wind  Power is a cubic function of wind speed V V X V X V  20% increase in wind speed means 73% more power  Doubling wind speed means 8 times more power

Power in the wind Effect of air density,  –Effect of swept area, A –Effect of wind speed, V R Swept Area: A = πR 2 Area of the circle swept by the rotor (m 2 ). Power in the Wind = ½ρAV 3
