The document summarizes key details about a 198 MW hydroelectric power plant including its components and operating principles. It describes the plant having 3 units each with 60 MW capacity upgraded to 66 MW. Key components discussed are the Francis turbine that converts kinetic energy of water to mechanical energy, the spherical valve, the rotor cooled by pressurized oil and the stator cooled by water from the turbine outlet. The output of the stator depends on factors like frequency which relates to rotor speed, and power which relates to head and water flow from the dam reservoir through tunnels.

7. TURBINE converts the
kinetic energy of
flowing water to
mechanical energy(to
the rotor).
Francis turbine is used

8. Carbon brushes
Cooling of rotor is by
the pressurized oil

9. Cooling of stator is by the
water from the outlet of
turbine, after filtration

10. OUTPUT from the stator DEPENDS upon some FACTORS
like :-
FREQUECY- depends upon the number of poles and speed of the rotor
ROTOR’S SPEED –depends upon the head of the DAM and flow rate of water
POWER FACTOR – It is the angle between current and voltage ,as P=VI COS
