How Does a Wind Turbine Work?

17th July, 2012

Wind power is exactly that, it is the process of converting the force of the wind into a current of electrons, more commonly known as electricity. This is achieved by means of a rotating generator which generates an electrical current by spinning coils of metal in close proximity to magnets. The electricity generated is then transported to the grid to service the homes of those living in the area.

 

Ensuring Even Production

The driving force behind this particular brand of renewable energy is the wind, but how do you get the generator spinning? The blades of the turbine are specially designed to catch the air flow so that the air passes over both sides of the blade. The rotating motion is caused by the angular design of the blade – the air pressure becomes uneven, higher on one side of the blade and lower on the other, therefore turning the turbine. At the top rear of the turbine is an anemometer, in effect a sophisticated weather vane. This measures the speed and direction of the wind and transfers this data to a central computer, thereby ensuring that the turbine faces into the wind – generating as much electricity as possible.

 

Powering the Generator

To generate electricity, the Endurance generator needs to rotate at a rate of 1500rpm and the blades rotate at 43rpm. The electricity generated is on large then transmitted to the national grid. However, private turbines have various options when it comes to installation costs and electricity usage. For example you could pay for installation privately and then benefit from the profit of selling the excess electricity back to the grid. Alternatively you could offer your land, on which a turbine would be installed, so that you would received reduce energy bills on a permanent basis. A further option would be to rent your land for the installation of the turbine and therefore received monthly rent payments.
