11. Constructional Features Of Turbo Generator
The two pole uses hydrogen cooling for rotor winding and direct water cooling stator winding.
Turbo generator consists of following parts:
STATOR
ROTOR
BEARINGS
SHAFT BEARINGS
Other additional auxiliaries:
Excitation system
Gas system

12. STATOR Stator consists of following parts: Stator frame Stator core
Stator winding
Locating bars
End shields
Terminal bushings
Phase connectors
Hydrogen cooler
End winding vibration
Supervision of generator

22. COOLING SYSTEM
The exciter is air cooled. The cooling air is circulated in a closed circuit and recooled in two cooling sections arranged along side the exciter. The complete exciter is housed in an enclosure draw the cool air in at both ends and expels the warmed air to the compartment beneath the base plate.The main exciter enclosure receives the cool air from the fan after it passes over the pilot exciter.

24. PERMANENT MAGNET EXCITER

25. Advantage Of Turbo Generator Over Hydro Generator
High frequency ,
N=120*f* π/ p
From here,
f=N*p/120 π
Here we see,
f is directly proportional to N
Less corrosion.
high stability.

26. CONCLUSION As steam is used so no site problem.
Turbo Generators are used where high frequency supply is required.
As steam is used so no site problem.
