POWER PLANTS :LECTURE 1, INTRODUCTION TO POWER PLANT

Power plant/Generation station is the special place where a bulk amount of electrical power is produced.
Power plant employs the prime mover which is coupled to a to an alternator. The prime mover coverts energy obtained from energy sources into mechanical energy which in turn drives an alternator to produce electrical power.
On designing of power plants the following aspects should be considered. One is that the selection and placing of the power generation equipment should provide a maximum return from the minimum expenditure invested over its working life.
Another is that the operation of the plant should be so as to provide cheap and reliable operation.
In this, we shall discuss the following power plants
1.Steam power plant
2.Hydroelectric power plant
3.Diesel power plant
4.Nuclear power plant
5.Natural gas power plant
Steam, diesel, nuclear and gas turbine power plants are called thermal power plants since they convert heat energy from the energy source into electrical energy.
Steam, gas turbine  and natural gas power plants are also called fossil-fueled power plants.
Fossil fueled power plants are the one which burns fossil fuel to produce electrical energy. Fossil fuels are fuel materials that are formed by the decomposition of animal and plant remains  long time years ago.\
Again steam,  nuclear, gas turbine, and diesel power plants are called convectional power plants because their energy sources are convectional sources.
Convectional sources are energy sources that are available in a limited quantity and once they are  used they get exhausted. Eg. Petroleum fuels, coal, biomass.
The hydropower plant is called non-covectional power plants as hydro energy is the non-conventional source of energy. Non-convectional sources are the ones that are not available in a limited quantity and once used they don't get exhausted. eg hydro-energy, wind energy solar energy.
This is a brief introduction to power plants. We shall explore more about these power plants in the coming lectures
