Principle of a thermal power plant
The generation of power in any coal oriented plant is based on the Rankine cycle.
In a rankine cycle:-
Coal is burnt in a boiler which converts water in to steam.
The expansion of steam in turbine produces mechanical power which drives the alternator.
Thus, the main equipment in the Thermal Power Plant consists of Boiler, Turbine and an alternator.
Main functions of a thermal power station
GENERATION:-
How the power is generated ?
Which method is used for moving the turbine?
In RSWM THERMAL POWER PLANT the power is generated by steam turbine and this steam is produced by coal.
TRANSMISSION :-
How much power is transmitted ?
HOW is the SWITCHYARD designed ?
In this plant 11kv generated and 132 kv is transmitted by a step up transformer.
PARTS OF THE POWER PLANT
According to the above mentioned functions the power plant has four main parts:-
C.H.P or the coal handling plant
Boiler
Alternator
Steam turbine
BOILER
Water tube boiler is used in this plant. Steam pressure at inlet is 102 kg/cm² & steam temp. at inlet is 535˚C. In this boiler , water is flow in the tube in furnace . Steam produces in tube & it collect in a drum which is situated on the top of boiler . Then steam goes to turbine .
The distributed control system(D.C.S)
A distributed control system (DCS) refers to a control system usually of a manufacturing system, process or any kind of dynamic system, in which the controller elements are not central in location (like the brain) but are distributed throughout the system.In R.S.W.M the D.C.S used is SPPA-T1000
