  1. The Workings of a Wind Power Plant

  2. Parts of the Plant generator blade tower transformer foundings http://www.motiva.fi/myllarin_tuulivoima/windpower%20web/fi/kids/index.htm

  3. The kinetic energy of air is transferred into electricity. source: glogster.com

  4. The Power of a Wind Energy Plant An air cylinder whose length is h=vt flows into the blades in time t The volume of the air cylinder V is then V=Ah=πr2vt The mass of the air in the cylinder m=ρairV=ρairπr2vt

  5. Starting from the efficiency, the output power is...

  6. Conclusions As can be seen from the pattern above, if... r (length of a blade) doubles, the output power quadruples (becomes 4 times bigger than what it was) v (speed of wind) doubles, the output power becomes 8 times bigger than what it was

  7. The Generator transforms kinetic energy into electricity is based on electromagnetic induction A moving magnet causes magnetic fields that are constantly changing. This change of magnetic flux causes a voltage in any conductor! In wind power plants it's wind that spins the magnet or actually the conductor itself.
