How Do Wind Turbines Do The Job?
Eco systems are being threatened by pollution. Air, water, and land are being contaminated by man's use of them. Non-renewable sources of energy like petroleum products release particles which convert into poisonous residues which are harmful to life on earth. The need of the hour is a turbine which uses wind to generate power, and does not leave behind any harmful carbon gases. But how do wind turbines work?
How a windmill functions explains the mechanics involved in the working of a wind turbine. It is necessary to ensure that all the parts function as a whole. A tower or number of towers at a distance from each other is constructed to utilize this type of energy. There should not be any hindrance to the free flow of wind.
Three blades, sometimes two, also known as rotors, are so designed that any pressure of the air on it causes it to move and produce a drag or resistance. The blades are designed at a forty five degree angle for efficient functioning.
These blades use a shaft fixed to a gearbox to transmit the air energy to a generator. These features differ from those used in a car where the gearbox is used to change speeds of the vehicle, and the clutch is engaged to make the change in speeds smooth and easy. The generator uses a motor to convert the kinetic wind energy into electricity.
This energy is transmitted through cables to a storage unit or to a grid for onward transmission to homes or large industries. Control units monitor each stage and record the amount of energy that is being generated. If this falls short or exceeds capacity then there is an automatic slowdown or shut off to avoid malfunctioning of the parts. There is also an automatic start factored in, which works when conditions are right.
Most sources of power have constant monitoring to ensure smooth functioning. Remote positioning of towers housing these turbines makes it difficult to physically manage the controls. It must be emphasized that all parts of the turbine will only work at their optimum if quality materials are used. Safety is of prime importance and should be built in so that sudden surges do not cause a breakdown.
The latest technology makes it possible to have sensors which can immediately identify any malfunctioning at any stage. A simple fact like keeping the blades clean can have a bearing on the overall functioning of a wind turbine.
There are a number of do-it-yourself kits available in the market today for making wind turbines. Smaller units can be fixed on the roof and can even supply and meet a household's energy needs. Go online and check out how the process works. Ensure that there is a steady wind blowing throughout the year. Also see if it is feasible to store the electricity generated in a safe manner. If there is not then have an alternative backup system for power needs of your household.
