12. Case #2: we performed a simulation of about 10,000 nods with 2,500 generators, close to 5000 controllers, and 18,000 other components, such as loads and
transmission line. For that size of grid, we obtained simulation performance between events, between fold or switching events, of 3.28 million seconds of real
computation time for a 10 millisecond simulated time which places us well within the real-time range for such a large network. During the occurrence of a
fault or a switching of event the extra calculations required to maintain the state of network brings us to a computational time of 7.4 milliseconds, still well
within the 10 milliseconds of simulated time and therefore, we maintain real-time capacity even during switching events.

14. Open & scalable hardware platform
Integrated with a chassis equipped with FPGA and I/Os
Interfaced with multiple communication protocols
The entire simulation
runs with one of our
target communicating
with your whole
computer so the
simulation can be
performed on your
desktop and accessing
remotely our chassis.
ePHASORsim also
integrates with a host of
test automation and
visualization platforms
such as our own product
TestDrive which allows
you to implement
realistic control panels
in Labview™ and
connect directly to
signals being read from
or sent to our simulator.
To obtain the biggest benefit from
ePHASORsim, you can count on our
open and scalable hardware platform
which allows you to integrate the
simulations that are being performed
with ePHASORsim together with
many communication protocols and
analog IO’s that you encounter in our
hardware products such as the
OP5600 series, 0P7000 series and so
on.
