Abstract
Models
for
dynamic
simulation
of
a
parabolic
trough
concentrating
solar
power
plant
were
developed
in
Modelica
for
the
simulation
software
Dymola.
The
parabolic
trough
power
plant
has
a
two-­‐tank
indirect
thermal
storage
with
solar
salt
for
the
ability
to
dispatch
electric
power
later
in
the
evening
and
during
the
night
when
little
or
no
solar
irradiation
is
present.
The
complete
system
consists
of
models
for
incoming
solar
irradiation,
a
parabolic
trough
collector
field,
thermal
storage
and
a
simplified
Rankine
cycle.
A
parabolic
trough
power
plant
named
Andasol
located
in
Aldeire
y
La
Calahorra,
Spain,

chosen
as
a

The

is
later
validated
against
performance
numbers
from
this
reference
system
in
order
to
make
sure
a
correct
implementation
has
been
made.
The
collector
and
solar
model
have
also
been
validated
against
different
papers
regarding
solar
collector
performance
and
show
good
results.
Finally
the
system
in
Dymola
has
been
simulated
during
a
day
for
different
parts
of
the
year
with
solar
data
from
the
same
region
as
the
Andasol
power
plant.
The
results
from
these
simulations
show
similarities
to
how
the
Andasol
power
plant
operates
and
how
well
the
system
performs
under
different
solar
irradiance
conditions.
By
modeling
the
system
dynamically
the
changes
in
insolation
over
time
can
be
studied
to
gain
information
about
how
it
affects
the

in
