ePHASORsim

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.

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.
