This is a special type of turbo generator which may find its usage in typical chemical plants. Here the steam in turbine comes from sulphuric acid plant.So no need of coal handling plant like in thermal power plants.

2. What is a
‘Turbo-Generator’?

3. Function of Turbo-Generator

4. Today we will discuss on
 Over view of Turbo-Generator (TG) system
Speed control system
Vaccum creation process
Gear Box
Parts of Generator
Automatic Voltage Regulator (AVR)
Brushless Excitation
Synchronization
Interconnection b/w incomers & outgoings lines
Load distribution of TG

10. Vaccum creation

11. Gear Box

12. Gear setup arrangement

13. PARTS OF GENERATOR
EXCITER STATOR
EXCITER ROTOR
ALTERNATOR ROTOR
ALTERNATOR STATOR

14. Automatic Voltage Regulator
(AVR)
 To supply dc excitation voltage after initial
start up by converting alternator‘s output ac
voltage to dc excitation voltage .
 To maintain the alternator‘s output voltage
at 415V ac.
Adjust excitation voltage in order to adjust
alternator‘s output voltage with either grid
voltage during synchronization process.

15. BRUSHLESS EXCITATION

16. SYNCHRONIZATION
 Same voltage.
 Same frequency.
 Same phase sequence.
 Same phase angle.
Necessary conditions :-

17. Interconnection b/w incomers &
outgoings lines of TG

18. LOAD DISTRIBUTION OF TG
 SAP II.
NEW MCC OF SAP I.
ZEOLITE BUILDING.
TANK FARM AREA.
RO PLANT (REVERSE OSMOSIS).
UTILITY PCC.
PACKAGE BOILER OF DM PLANT.

19. SUGGESTIONS
Old relays should be replaced with
microcontroller and microprocessor based relay.
 PLC based Control System should be
implemented.
New filter less CPC should be installed as filters
can only be cleaned during shutdown process.
Ammeters should be installed in order to check
individual loads.
