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)
5
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 (10-250 kW) Village Power Hybrid Systems Distributed Power

Nacelle 56 tons Tower 3 sections Workers Blade 112’ long
9
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
10
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
11
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
