The world is consuming 19,090 TW of
electrical energy at present with a
population of 7.071 billion.
By 2050 the population will reach 10
billion and people will require at least
36,000 – 82,000 TW of electrical
energy.

Alternators
Section 3
Alternators are the machines
which convert mechanical
energy into electrical energy.
The mechanical energy input to
the alternators is obtained from
turbines.
12. Power Generation
Alternators are coupled
to turbines which
converts heat energy
into mechanical energy.
Each plant consists of
several alternator units
for the generation of
power.

The power generated in the
generating units is transmitted
with the help of transmission
lines.
Before transmitting the power
the Voltage level is increased
with the help of transformers
