SURATGARH SUPER THERMAL POWER STATION Presentation Transcript:
1.SURATGARH SUPER THERMAL POWER STATION

2.SURATGARH SUPER THERMAL POWER STATION
It has generation capacity of 1500 MW and installed with six units of 250 MW each
It is a coal based thermal station
Coal is received from coal fields of MP , Jarkhand
Water is received from Indira Gandhi Canal

3.INSTALLED CAPACITY

4.SITE SELECTION OF THERMAL POWER PLANT
Nearest  to the load Centre
Availability of  water
Land requirement
Ash disposal
Transportation  facility
Distance  from  populated  area
Availability of coal

5.BASIC PHENOMENON OF ELECTRICITY GENERATION

6.BASIC COMPONENT
Steam Turbine
Boiler
Generator
Booster pump
Cooling  Tower
Switch yard

7.STEAM TURBINE
Steam turbine is a rotating machine which CONVERTS HEAT ENERGY OF STEAM TO MECHANICAL ENERGY
The Thermal Power Plants with steam turbine uses Rankine cycle
The turbine is of tandem compound design with separate HP, IP and LP cylinder. The HP & IP turbines are of single flow type while LP turbine is of double flow type.

8.STEAM TURBINE
SPECIFICATION

TYPE CONDESING                                TENDEM
RATED OUTPUT OF TURBINE               250KW
RATED SPEED                                       3000RPM
MAIN STEAM TEMPERTURE                537 DEG. C
RATED PRESSURE                               150 KG/CM

9.BOILER
It converts fuel energy into steam energy
The fuel may be furnace oil, diesel oil, natural gas or coal
The boiler installed in S.T.P.S. are made by BHEL
Continuous steam output of 375 tons/hour at 138 kg/cm2 pressure and 540 degree cent. Temp

10.Generator
Generator is directly coupled with    turbine and it convert mechanical energy into electrical energy
Energy conversion is based on the principal of the production of dynamically
In this plant water cool generator is used for generating electricity
Speed 3000 rpm/50Hz.

11.Booster pump
50 % tandem boiler feed pump sets are supplied to this contact, three pump sets for each boilerThe booster pump is a single stage, horizontal, axial split casing type, having the suction and discharge branches on the casing bottom half
Hence it allows the pump internals to be removed without disturbing the suction and discharge pipe work of the alignment between the pump and the motor.

12.COOLING TOWER
A cooling tower is an equipment used to reduce the temperature of a water stream by extracting heat from water and emitting it to the atmosphere.
Cooling towers make use of evaporation where by some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere.

13.SWITCH YARD
220KV SYSTEM :-
Each of the generator is connected to this system through a step up of 125 MVA 240/ 11 KV yard generator transformer.  There are two step down transformer each feeding 6.6 KV system (Station Switchyard ).
Four feeder take off from 220 switch yard two to SAKATPURA ,GSS  and other to HEERAPURA, Jaipur GSS.
220 KV System :-
   i). CIRCUIT BREAKERS
   ii). ISOLATOR

14.C.B & ISOLATER
These are used for automatic switching during normal or abnormal conditions . There are SF6 circuit breaker is used .
There are four types of C.B.
     Air blast C.B.
     Oil C.B.
     Vacuum C.B.
      SF6 C.B.
ISOLATER:-    These are used to disconnection transmission line under no-load condition for safety
