Real-time digital simulation (RTDS) has become indispensable for validating protection relays, HVDC controls, and inverter-based resource (IBR) controllers before they are deployed on live grids. RTDS Technologies' RSCAD software suite, running on the company's purpose-built NovaCor and PB5. The real-time digital simulator lab provides real-time dynamic simulation of system faults, sequence of events, and/or conditions such as power swings, open poles, out of step conditions and other fault and system conditions. Real-time EMT simulations enable highly efficient, detailed studies of the power system, allowing engineers to anticipate system and device behaviors that threaten the stability. RelaySimTest is a software solution for system-based protection testing with OMICRON test sets. The software simulates realistic operational statuses and faults in the electric network to check whether the protection system is working as it should. Hence, Hardware-in-the-Loop (HIL) testing is an efficient method to perform closed-loop testing of a relay since numerous fault cases can be simulated to provide a realistic operating environment for the relay under test.
