RTDS Technologies is excited to announce the release of RSCAD Version 5 (click here to download the information sheet). This new version of the RSCAD software offers many new advantages to users of the RTDS Simulator, including an overhauled compiler, Distribution Mode, and FPGA-based SV streaming. Among these new features is the removal of many fixed hard limits. Limits still exist in RSCAD V5, but they depend entirely upon available resources rather than fixed upper limits.
The following is a list of previous hard limits that have been removed and are now resource-dependent in RSCAD V5:
G-matrix overlays: Maximum of 160 in RSCAD V4
Passed G-values: Maximum of 230 in RSCAD V4
Current injections: Maximum of 400 in RCSAD V4
Switches (breakers/faults): Maximum of 100 per network solution in RSCAD V4
Branch currents and node voltages passed over the backplane: Maximum of 300 in RSCAD V4
Characters in export/import: Maximum of 7 in RSCAD V4
RLsplit components: Maximum of 50 in RSCAD V4
Control components per Draft case: Maximum of 30,000 in RSCAD V4
Absolute minimum timestep: 9.9999 microseconds in RSCAD V4
Number of branches: Maximum of 200 for 1 network solution, 300 for 2 network solutions, and 800 pure resistive branches in RSCAD V4
Serial memory (sliders, dials, pushbuttons, switches): Maximum of 128 per processor in RSCAD V4
Racks in the config file: Maximum of 39 per processor in RSCAD V4
Additionally, the maximum number of backplane transfers (variables that can be communicated over the rack backplane) has been increased from 1000 in V4 to 2000 variables in V5.
Furthermore, the algorithm for automatic processor assignment – the one that assigns power system components to various processors available in the rack – has changed. Previously, this algorithm focused on balancing the load as evenly as possible among available processors. In RSCAD V5, the algorithm focuses instead on minimizing backplane transfers. Power system components connected to a common bus are now targeted to be placed on the same processor so as to reduce the total number of variables that need to be passed to the network solution processor.
