Combined
Operations
of
Power
Plants
It
is
the
aim
of
the
national
economy
to
create
the
maximum
amount
of
generating
capacity
with
the
available
funds
and
to
generate
power
at
as
cheap
rate
as
possible.
Power
supply
industry
is
highly
capital
intensive
and
therefore
it
is
desirable
to
utilise
in
optimum
manner
once
generating
facilities
become
available.
Before
the
investment
of
huge
amount
in
this
industry,
the
most
economic
generating
scheme
should
be
selected
to
supply
power
at
lowest
cost.
Once
the
generating
facilities
(different
power
plants)
are
made
available,
it
is
important
to
have
integrated
operation
of
neighboring
power
systems
so
that
maximum
energy
generation
takes
place
from
power
stations
like
thermal
and
nuclear
and
maximum
energy
and
capacity
are
utilised
from
the
hydro
stations.
This
can
be
only
achieved
by
closely
combined
operation
of
different
power
systems
which
if
operated
individually
cannot
be
utilised
to
the
maximum
advantage.
Therefore,
it
is
necessary
that
the
power
systems
of
the
different
states
must
be
interconnected
to
yield
the
maximum
benefit.
The
U.S
national
power
survey
estimated
that
the
reserve
.capacity
of
power
systems
required
in
U.S.
can
be
reduced
from
17%
to
8%
by
198I,
with
the
same
reliability
if
fully
coordinated
.operation
of
all
the
country's
resources
was
carried
out.
In
India
also,
the
reserve
capacity
requirements
can
be
considerably
reduced
by
having
fully
coordinated
operation.
Interconnected
power
system
can
provide
large
savings
both
in
Capacity
and
fuel
cost.
In
order
to
achieve
optimum
utilisation
of
resources
and
at
the
same
time
ensuring
reliability
and
continuity
of
power
supply,
proper
administration
and
technical
set-up
has
to
be
created.
No
doubt,
the
rapid
pace
of
interconnection
between
the
power
systems
can
greatly
improve
the
continuity,
security
and
integrity
of
power
supply
if
it
is
associated
with
sound
mechanism
for
monitoring
and
control.
