Wind Turbine
Wind Turbine Power Plant As An Alternative
The decline in water level in various dams, those used as sources of hydroelectric power (hydropower)-has lowered the electricity supply in Java up to 500 megawatts. As source supplier of electricity, with hydroelectric power plants (power plant) and gas power plants (power plant) does play an important role on the availability of electricity, in Java, Madura, and Bali. Actual wind energy is considerable in Indonesia was not used as an alternative to producing electricity.
In fact, in plenty of countries, the utilization of wind energy as an unconventional alternative energy sources are increasingly gaining attention. This is of work driven by the emergence of awareness of the energy crisis by the fact that energy demand continues to increase so great. In addition, wind energy is a source of limitless so the utilization of wind energy conversion systems will have a positive impact on the environment.
Origin of wind energy
all renewable energy and energy even on fossil-fuel energy accept tidal and geothermal-derived from the Sun. The sun radiate one.74 x 1014 kilowatt hours of energy to Earth every hour. In other words, the earth receives one.74 x 1017 watts of power.
About 1-2 percent of the energy is converted in to wind energy. Thus, wind energy totaling 50-100 times over the energy converted in to biomass by all plants that exist on Earth.
The mechanism of wind turbines
a wind power plant can be created by combining several wind turbines to generate electricity to power distributor unit. Electricity flows through the transmission cables and distributed to homes, offices, schools, and so on.
Types of wind turbines
in the work of its development, wind turbines are divided in to types of wind turbine propeller and Durries wind turbine. Both types of turbines this is now gaining great attention to create.
Utilization is now often used is to pump water and power plants.
Wind turbines are propeller type wind turbines with horizontal axis like a propeller aircraft in general. Wind turbines ought to be directed in accordance with the highest wind speed.
The wind speed was measured with an tool called an anemometer. Anemometer type of bowl is the most widely used. Cup anemometer has a vertical axis and serves of fruit bowls catch the wind.
