The fiber enhanced backplane was recently developed in order to reduce the communication time required by the RTDS Simulator. It provides offloading of some backplane data transfers by using fiber cables to transfer data directly between component models and the network solution. This reduces the simulation timestep and/or provides additional time for more calculations. The ability to perform more calculations has allowed us to increase the size of the network solution. Customers will now be able to simulate 90 single-phase nodes (30 three-phase buses) per network solution instead of the previous limit of 72 single-phase nodes (24 three-phase buses).
This feature paves the way for emerging power system components that require more data transfers and impose more load on the backplane. Using the fiber enhanced backplane, limits on the number of data transfers can be increased, which is a huge benefit to our customers who have reached these limits in their more complicated simulation cases. The fiber enhanced backplane can reduce transfer time by up to 38%. Transfer time is reduced most significantly for heavier simulation cases utilizing more processor cards.
