What is Electricity? Electricity is energy transported by the motion of electrons **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 = I2xR (watt) Faraday Effect
Types of Electricity Generating Windmills • Small (10 kW) • Homes • Farms • Remote Applications • (e.g. water pumping, telecom sites, icemaking) • Intermediate • (10-250 kW) • Village Power • Hybrid Systems • Distributed Power • Large (250 kW - 2+MW) • Central Station Wind Farms • Distributed Power
Workers Blade 112’ long Nacelle 56 tons Tower 3 sections Wind Turbine Perspective
Large Wind Turbines • 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
Importance of Wind Speed • 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 X V X V • 20% increase in wind speed means 73% more power • Doubling wind speed means 8 times more power
Calculation of Wind Power • Power in the wind Effect of air density, • Effect of swept area, A • Effect of wind speed, V Power in the Wind = ½ρAV3 R Swept Area: A = πR2 Area of the circle swept by the rotor (m2).
