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).
