Overview of Generating power plant
In the modern world the need of electricity is increasing very rapidly from domestic purposes to large industrial sector so it became necessary to produce electricity in large scale and economically.This large scale energy production could be achieved by means of suitable power producing units named ‘Power Plants or Electric Power Generating Stations or Electric Power Plants.There are mainly two aspects that should be given care while constructing or designing a plant,the first one is that the selection of equipment for the plant should be able to give maximum output ie in the form of electricity with minimum input.Input depends on the type of plant we are designing like coal,diesel,nuclear power etc and at the same time these equipments should have longer life.The second aspect is that the plant should be able to give cheap,reliable and uninterrupted service.
Generating stations
Bulk electric power is produced by special plants know as generating stations or power plants.
A generating station should consists of a prime mover coupled to an alternator to produce electric power.The prime converts different energy forms like kinetic energy,potential energy,chemical energy etc into mechanical energy.The alternator converts the mechanical energy into electrical energy.The electrical energy so produced is transmitted to consumers by means of conductors called transmission lines.The prime mover and the alternator forms only the basic part of the generating station,other than this a lot of auxiliary equipments and devise are employed for a consistent and continuous power production.
Depending upon the energies or input converted by prime mover into mechanical energy,the generating stations are classified as follows
(1)Steam Power stations (2)Hydro Electric Power Stations
(3)Diesel Power Stations (4)Nuclear Power Stations
