Wind power generation is the conversion of wind energy into a useful form of energy, such as using wind turbines for electricity (electric power generation), wind mills for mechanical power, wind pumps for pumping water or drainage, or sails to propel ships. Wind energy is one of efficient alternate energy sources.

Key Points of Electric Power Generation from Wind Energy

  • A wind farm is a group of wind turbines in the same location used for production of electric power. A large wind farm may consist of several hundred individual wind turbines.
  • wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy is used to drive machinery, such as for grinding grain or pumping water, the device is called a windmill or wind pump.
  • Wind energy “penetration” refers to the fraction of energy produced by wind compared with the total available generation capacity.
  • Power Grid energy storage can store energy/electricity developed by wind turbines. High energy density batteries are used for wind power storage in wind power grids.
  • Offshore wind power refers to the construction of wind farms in bodies of water to generate electricity from wind. Better wind speeds are available offshore compared to on land, so offshore wind power’s contribution in terms of electricity supplied is higher.
  • Small-scale wind power is the name given to home based wind power generation systems with the capacity to produce up to 50 kW of electrical power. Wind turbines have been used for household electricity generation in conjunction with battery storage over many decades in remote areas.
  • Wind power generation setup has negligible fuel costs, but a high capital cost.
  • The environmental effects of wind power are relatively minor. Wind power consumes no fuel, and emits no air pollution, unlike fossil fuel power sources.
  • Net Energy Gain (NEG) refers to the difference between the energy expended to harvest an energy source and the amount of energy gained from that harvest. NEG = EnergyConsumable − EnergyExpended.

Components of Wind Power Generator

  • Wind Turbines to convert wind energy into mechanical energy. Vertical/Horizontal-axis wind turbines (VAWT or HAWT)
  • Induction generators to convert mechanical energy into electric power
  • Reactive power required for excitation of Induction generators
  • Capacitor banks for power factor correction
  • High energy density batteries for wind power storage in wind power grids

Applications of Wind Power Turbines/Generator’s Electricity

  • Wind powered vehicles (cars, battery motor cycles, lightweight three-wheelers) that utilizes wind energy as primary or alternate fuel/power source
  • Small-scale Wind power generators for home/residential/domestic electric power generation
  • Large-scale Wind Forms as Wind Power Plant for electric power generation & transmission to large industries/towns/cities
  • Portable Wind Charger – A personal wind power battery charger uses wind power to charge your phone, or camera, run a personal fan, or charge batteries or your GPS, while you are riding a bike, walking, camping, or any other outdoor activity.
