2. About KBUN Plant

3. Process of Generation of Electricity

4. Coal to Steam (Coal Handling Plant)

5. Coal to Steam (Coal Handling Plant) Coal Coal

6. Coal to Steam (Steam Generation)

7. General Layout of a Thermal Power Plant

8. Steam to Mechanical Power (Turbines)

9. Steam to Mechanical Power (Turbines)

10. Power Generation Rating Continuous Active Output 110 MW Rated Voltage 11000 + / - 5%V Rated Current 7220 A Power Factor 0.8 Lagging Frequency 50 Hz Excitation System Static type Field C urrent at Rated Output 1335 A Type of Cooling System Hydrogen Cooled Hydrogen Pressure 2 Ata No. of H₂ Cooled Elements 06 Cooling Medium for H₂ Soft water

11. Mechanical power produced at the shaft of the turbine is used to rotate rotor. Rotating Magnetic flux produced by rotor cuts stator conductor flux and from electromagnetic induction, electricity is produced . Rotor runs at 3000 rpm, produces 3-phase voltage at 11kv , and of 50 HZ frequency. Oil shielded hydrogen is used for the cooling purpose of generator. Power Generation

12. Power Transmission

13. Control Room It is the brain of any substation. All necessary steps about Transmission , protection, Charging etc. are carried out in the control room. Measuring instruments of the control room:-

14. Control Room

15. Switchyard It consists of following equipments :-

16. Switchyard

17. Do You Know Why cylindrical pipes are used in switchyard instead of wire conductor ?

18. Do You Know Why cylindrical pipes are used in switchyard instead of wire conductor ? Because of following purpose :- Safety. Reduce Ferranti Effect. Reduce the effect of vibration during opening and closing of circuit breakers and isolators.

19. Do You Know Why motor is used to rotate the shaft of turbine, when the turbine is not in operation? Motor

20. Do You Know Why motor is used to rotate the shaft of turbine, when the turbine is not in operation? This is because in case of any fault if production of plants stops then bearing motor rotates rotor shaft of turbine continuously at 65 rpm. This is because if shaft doesn’t rotate then due to load it may bend.
