Working of wind power systems

Wind always blows on the surface of the earth. This makes wind an inexhaustible, clean and renewable energy source. The most common method of harnessing renewable wind energy is using wind turbines that can generate wind renewable power. The components of wind power systems are wind turbine, a tower, wires and connectors and inverters or batteries.

The main components of wind turbines are a rotor, a generator and a tail. The rotor has two or three blades that move after gaining renewable wind energy. The rotating blades then turn on a generator which converts the renewable wind energy to electrical energy that can be used for several purposes. The tail of wind power systems ensures that the turbines can capture maximum wind renewable energy and can generate the maximum amount of electricity possible. Generally, the wind turbines are installed at heights so that they can capture maximum wind renewable energy to generate massive amounts of electricity.

The different types of towers used in wind power systems are free standing and guyed towers. Guyed towers are the least expensive towers that are available. They have a simple framework tat consists of metal strips supported by guy cables and earth anchors. This makes them are easy to use, repair and maintain. Free standing towers or stand alone systems are the ones that use batteries to store excess wind power generated.

Wind power systems are connected to grid connected systems. In this case, the wind renewable power is used to generate electricity. The electricity so produced can be put to several uses in wind power homes and also at commercial sites.
