How Wind Energy Equipment Operates

حجم الخط

By John Taylor


Wind is a renewable source of energy that can easily be tapped and has little environmental effects. Wind energy equipment usually relies on a turbine for operation. Moving air is used to propel blades found in a turbine. A rotor found within the blades is also used to spin a generator and in turn, electricity is produced. There is a comprehensive process about how a turbine works.

Turbines resemble fans in design and structure. They however operate differently when compared to usual fans. They utilize moving air to power a generator that produces electricity. Moving air is a form of solar energy that is produced when the atmosphere is heated by the sun. Moving air spreads at varying speeds depending on the topography of a landscape. Flat terrains are the best for tapping moving air.

Turbines also have the ability to convert kinetic power produced when air moves through the blades. These mills convert kinetic power to a reliable form of mechanical power suitable for generating electricity. High velocities of air in motion usually result to the generation of high electrical voltages. Furthermore, flat terrains ensure that kinetic power is relatively high.

Mills that transform air in motion to electricity are categorized into two classes. This classification is based on how they are mounted on a landscape as well as the type of terrain where they are found. To be precise, a mill can be positioned either horizontally or vertically on a terrain. Mills can also be built on flat landscapes and on water bodies like oceans and lakes. Turbines that are built on large water bodies are called offshore mills.

The turbines used to propel moving air also vary in size. The average size is one hundred kilowatts. There are other mills that produce thousands of megawatts based on how they have been constructed. Large turbines are usually built on open air lands to produce bulk power that is connected to an electrical grid. Over the years, investors in the power industry are tapping moving air from water bodies because of its potential to produce thousands of megawatts.

Low voltage mills are suitable for powering houses, water pumping machines and telecommunication dishes. They can be used in such contexts because their electrical power production is significantly low. These devices are also suitable for powering small voltage batteries and diesel powered generators.

Electric charge produced from mills varies with time. This amount can be different in an hour, after twenty four hours or in a month. Annual variations of power produced by turbines also exist but they are not significant. This is because electricity production and consumption should be at equilibrium always to sustain grid stability.

The wind industry amasses thousands of revenue hence strengthening the economy. The construction of large turbines in flat terrains also receives enormous support in terms of finances to encourage development. More sophisticated mills are also manufactured by mechanical industries to cope up with the large amount of power generated from moving air.
