Traditionally,
applications
of
the
digital
real-time
(RT)
simulator
in
power
system
studies
were
limited
to
performance
evaluation
of
relay/protection
systems.
In
such
applications,
a
small
part
of
an
interconnected
system
is
simulated
in
a
RT
simulation
environment
and
the
simulated
signals
are
communicated
to
a
physical
relay/protection
platform
in
an
"open-loop"
fashion.
Recent
proliferation
of
electronically-coupled
apparatus
in
power
systems
has
introduced
unconventional
and
more
sophisticated
controls
that
often
include
custom-tailored
and
proprietary
hardware/software
modules
which
do
not
lend
themselves
to
the
conventional
digital
time-domain
simulation
methods
and
in
particular
to
RT
simulation
methods.
Consequently,
the
concept
of
control
hardware-in-the-loop
(HIL),
based
on
RT
simulation
of
power
system,
has
emerged
as
the
approach
for
design,
development
and
testing
of
hardware-based
control
platforms.
In
spite
of
the
recent
developments
in
microelectronics
and
the
availability
of
powerful
processors,
technical
challenges
and
excessive
cost,
associated
with
RT-HIL
platforms
for
representing
a
realistic-size
system,
have
not
been
addressed.
This
presentation:
•
highlights
barriers
to
real-time
hardware-in-the-loop
simulation
of
large
power
system;
•
discusses
recent
R&D
trends,
in
hardware
and
software,
to
enable
real-time
simulation
of
a
realistic-size
power
system
at
reasonable
infrastructure
cost;
•
presents
examples
of
RT-HIL
simulation
case
studies.
Speaker:
Reza
Iravani
received
his
B.Sc.
degree
in
1976
(Iran)
and
until
1979
worked
as
a
consulting
engineer.
He
received
his
M.Sc.
(1981)
and
Ph.D.
(1985)
degrees
in
electrical
engineering
from
the
University
of
Manitoba,
Canada.
Presently,
he
is
a
professor
in
the
Department
of
Electrical
and
Computer
Engineering
at
the
University
of
Toronto,
Canada.
His
research
interests
include
modeling,
control,
and
dynamics
of
interconnected
HVDC-AC
power
grids.
