INTRODUCTION
The Kota Super Thermal Power Station is ideally at the left bank of Chambal River at Up Stream of Kota Barrage. The large expanse of water reached by the barrage provides an efficient direct circulation of cooling system for the power station. The 220 KV GSS is within ½ kms. from the power station. It comes under RRVUNL(Rajasthan Rajya Vidhyut Utpadan Nigam Ltd).

FUEL FOR KSTPS
In thermal power stations fuel required to generate power is coal. Coal India Limited is supplying coal from its coal mines of coal producing subsidiaries BCCL, SECL & ECL to KSTPS through railway wagons. The source of water for power station is reservoir formed by Kota Barrage on the Chambal River.

ELECTRICITY GENERATION AT KSTPS
Super Thermal Power Station burns the fuel and use the heat to raise the steam which drives the turbo-generator. Object is to convert heat in to mechanical energy then to electrical energy by rotating a magnet inside the set of winding. In a coal fired Super Thermal Power Station other raw materials are air and water.
A thermal power station is said to be as Super thermal power station if its generation is above 1000MW.
Kota super thermal power generates 1240 MW of power.

PARTS OF THERMAL POWER PLANT
• • • • • •
Coal handling plant Ash handling plant Boilers Steam turbines Transformers Turbo generators
6
COAL HANDLING PLANT
There are different part of coal handling plant:(i) Wagon unloading system (ii) Crushing System (iii) Conveying system
7
ASH HANDLING PLANT
This plant is further divided into three parts:(i) Fuel & Ash plant (ii) Air & Gas plant (iii) Ash disposal & Dust collection plant
8
BOILERS
The boilers are large capacity steam generators used purely for the steam power generation. In boiler heat energy is released from the combustion of fossil fuel and heat is transferred to different fluids in the system and a parts of it is lost or left out as unutilized. It has three main parts: (i) Heat transfer mode (ii) Heat transfer surface arrangement (iii) Heat transfer section
9
TRANSFORMERS
A transformer may be defined as equipments based on electromagnetic induction, alternating current and voltage without affecting frequency. It has mainly two windings i.e. primary winding and secondary windings. It has mainly conservator, breather, cooling fans.

TURBO GENERATOR
Stage-I(Unit-1,2):
Manufacturer Rated voltage Rated current Rated speed Capacity BHEL 11kv 7200amp 3000rm 137.5MVA
The main function of generator is to convert mechanical energy to electrical energy.
Stage-II,III(3,4,5):
Manufacturer Rated voltage Rated current Rated speed Capacity BHEL 15.75kv 9050amp 3000rpm 247MVA BHEL 15.75MVA 9050Amp 3000rpm 247MVA
Stage-IV,V(6,7):
Manufacturer Rated voltage Rated curent Rated Speed Capacity
There are three main parts of generator: (i) Stator (ii) Rotor (iii) Slip rings
11
STEAM TURBINES
Active output Rated speed Steam press Steam temp Wt. of turbine Overall length
210MW 3000rpm 150kg/cm2 535°c 475tons 16.975 mt
Turbine is a machine in which a shaft is rotated steadily by impact or reaction of correct or stream of working substance (steam , air , water , gases etc) upon blades of a wheel. It convert the potential or kinetic energy of the working substance into mechanical power by virtue of dynamic action of working substances. When the working substance is steam it is called the steam turbine.
12
D.C. SYSTEM
It mainly consists of three parts: (i) Rectifiers (ii) Filters (iii) Blocker diodes
Rectifiers are used to convert A.C. supply to D.C. supply.
Rectifiers are of two types: (i) Half wave rectifiers (ii) Full wave rectifiers
13
ESP(Electrostatic Precipitate)
In an ESP the dust lidded gas is passed through an intense electric field, which causes ionization of the gases.
14
SWITCHYARD
Two 220 KV bus bars have
been provided in switch yard and are inter-connected through a bus coupler. It consists of several parts: (i) Bus bars (ii) Circuit breakers (iii) Current transformers(C.T) (iv) Potential transformers(P.T.) (v) Isolators (vi) Lightning Arresters

CONCLUSION
Kota super thermal power station generates 1240 MW power It also provides an opportunity to learn how the technology is used at proper place and time can have a lot of labor e.g. Wagon Tripler . However training has proved to be quite fruitful. It has allowed an opportunity to get an exposure of the practical implementation to theoretical fundamentals.
