Wind Energy

What are the main Components of a Wind powered electric generator?

Written By Admin, on Saturday April 21st 2009


The main components of a wind powered electric generator are as follows:

  • Wind Blades- Wind blades turn kinetic energy of the wind into mechanical energy that is required to rotate the electric generator.
  • Permanent Magnet Generator (PMG)- An alternate current is formed at non-rotating coil section when permanent magnetic section rotates.
  • Diodes circuit – Alternate current (AC) that is produced by the generator is converted into Direct current (DC) by this Diode circuit.
  • Head frame – Generator’s Wind blades, Tail etc. are fixed on to this head frame.
  • Tail - Wind blades section is directed towards the blowing wind by the tail.
  • Wind tower - This is used to fix the generator at a height above the ground.
  • Base plate - Helps to fix the wind tower in vertical position.
  • Guide wires - Helps to keep wind tower in vertical position.
  • Current caring cables - The cables which used to carry electric current from generator to battery.
  • Rechargeable battery - is used to store electric current generated by the generator
  • Charge controller – This unit helps to divert any excess current after recharging the battery to the blast unit. This process helps to protect the battery from overcharging.
  • Blast load - After recharging the battery, the excess current which is diverted by the charge controller is defused by the blast controller.
  • Inverter – Direct current (DC) which is stored in the battery is converted into alternate current by this devise.
