2. ABOUT BHEL
BHEL was established in 1960’s in Bhopal under
Indo-Soviet agreement.
Largest engineering and manufacturing enterprise
in India.
Got 'Maharatna' status on 1 Feb,2013.
BHEL has a share of 59% in India’s total installed
generating capacity of power.
BHEL filed 351 patents and copyrights with various
organization.
6. TURBO-GENERATOR
•
•
•
•
•
Turbo generator operates on the fundamental principles
of ELECTROMAGNETIC INDUCTION.
It converts mechanical energy into electrical energy.
It is a turbine directly connected to electric generator for
the generation of electricity.
Mechanical motion is generated in turbine by using
heat.
Turbo generator rotor is filled with hydrogen gas which
is used to prevent the coil from decaying.
11. EXCITATION SYSTEM
•
•
The process of generating a magnetic field by
means of an electric current is called excitation.
It provides power to the field windings thus produce
field for rotor.
Types of exciter:
Brush type exciter / Static excitation
Brush less exciter
12. BRUSH TYPE/STATIC EXCITATION
Rotor Field Winding is connected to Slip ring
mounted on Rotor.
Excitation is provided by current transfer by contact
through Carbon Brushes, Slip ring and field lead.
14. ADVANTAGE OF BRUSH LESS EXCITER
OVER BRUSH TYPE EXCITER
Eliminates Slip Rings, Brush gear and Field Breaker
Eliminates all problems associated with transfer of
current via sliding contacts
Eliminates the Hazard of changing Brushes on Load
Brush Losses are eliminated
