what is electricity
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

 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
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

Wind Turbine Perspective
large wind turbines
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
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
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).
