How Wind Energy Power System Work and Its Advantages?

Wind Energy Power System

  • Wind energy power system is an indirect form of solar energy, because wind is mainly induced by the uneven heating of the earth's surface by the sun.
  • Winds can be classified as planetary wind and local wind.
  • Planetary winds are caused by greater solar heating of the earth's surface near the equator; whereas local winds are caused by differential heating of land and water, and also by hills and mountain sides.
  • During the operation, the wind approaching the blades moves the wind null shaft thereby rotating the rotor of generator.
  • In this way, kinetic energy of the wind is converted into mechanical energy by the wind mill and then converted into electrical energy by using a generator.
  • Figure shows the general layout of wind energy power system.

Advantages of wind energy power system

  • Wind is available at no cost.
  • It does not cause any kind of pollution while generating power.
  • It is available in many off-shore, on-shore and remote areas which is helpful in supplying the electric power in those areas.
  • It has low maintenance cost and low power generation cost.

Disadvantages of wind energy power system

  • It is favourable in locations which are away from cities.
  • The wind supply is variable, unsteady, intermittent and sometimes dangerous also.
  • The initial cost of plant set-up is high.
  • It has low energy density.
