INTRODUCT IONElectricity is a form of energy and occurs in nature. It was not invented.

The discovery of electricity happened some six hundred years ago. Some give credit to Benjamin Franklin, who helped to establish the

connection between lightning and electricity.It is one of those discoveries that have changed the daily life of

everybody on the Planet. The point is, without electricity, modern day life will simply come to a stop. In fact, the advancement of a country is measured by the index per capita consumption of electricity – more it is

more advanced the country is.So the generation and distribution of electricity is necessary to fulfill the

need of people all over the world.

GENERAT ION OF ELECTRIC ITY

Electricity generation is the process of generating electrical power from different form of energy. The fundamental principles of electrical generation were discovered during 1820s and early 1830s by the British scientist Michael Faraday.

Power is produced in various kinds of power plants and electric power generating stations. A generating station essentially employs a prime mover coupled to an alternator for the production of electric power.

Generation, transmission and distribution of electric power in our country is carried out as 3-phase system at 50 Hz.

TYPES OF POWER GENERATING STATIONS

THERMAL POWER STATION HYDROELECTRIC POWER STATION NUCLEAR POWER STATION

In a thermal power plant coal is burnt to produce high temperature and high pressure steam in a boiler. The steam is passed through a steam turbine to produce rotational motion. The generator, mechanically coupled to the turbine, thus rotates producing electricity.

The fuel(coal) for this power plant is quite cheap and the installation cost for this power plant is less compare to other. But its pollutes the atmosphere due to the production of large amount of smoke and its running cost is higher compared to hydroelectric plant

This generating station utilises the potential energy of water at a high level for the generation of electric energy.

It requires no fuel as it fully depends on water, it is quite neat and clean as no smoke or ash are produced, and requires very small running charges. But the installing cost of dam is too high and requires skilled and experienced hands to build the dam.

In this generating station nuclear energy, which is produce by nuclear fission of , is converted into electric energy.

It produce a bulk electric power from a very small amount of fuel and hence its running charge is small. But the fuel is expensive and hard to recover and it cause danger amount of radioactive pollution

DISTRIBUTION OF ELECTRIC POWER

The huge amount of power generated in a power station (hundreds of MW) which is transported over a long distance (hundreds of kilometres) with the help of transmission line and transmission towers, then it is distributed to different industry and for domestic purpose.

The electric power is transmitted by overhead line or by under ground cable.

The generated power is step up by the transformer and transmitted to the substation, which is there step down and distributed to the consumer.
