Real Time Digital Simulator
Real Time Digital Simulator or RTS as the abbreviation recommended by IEEE committee on real-time simulator applied for power systems provides power systems simulation technology for fast, reliable, accurate and cost-effective study of power systems with complex High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) networks. The RTS is a fully digital electromagnetic transient power system simulator that operates in real time.
HYPERSIM is one of the commercial RTS available, it has been developed by Hydro-Québec and eMEGAsim has been developed by OPAL-RT Technologies Inc. which was born within Hydro-Québec. HYPERSIM is now available from OPAL-RT Technologies.
RTDS is the trademark for the RTS simulator provided by RTDS Technologies.
About
The system's graphical user interface, proprietary software and mathematical algorithms can simulate any modern electric power grid configuration. As new equipment or components are added or subtracted from the simulator's configuration, the model instantly updates. For example, researchers can run simulated system-failure scenarios such as a control system cyberintrusion or a physical damage event such as a terrorist attack or natural disaster and instantly detect the order and reasoning for why dedicated relays, breakers or substations failed.
Advantages
Because the simulator functions in real time, the power system algorithms are calculated quickly enough to continuously produce output conditions that realistically represent conditions in a real network. Real-time simulation is significant for two reasons—the user can test physical devices and the user is more productive by completing many studies quickly with real-time simulation.

- Apart from time domain simulators a so-called frequency domain real time simulator has the advantage of being fast and can be used for large scale power systems. Millions of devices and controllers including the relays actions will be simulated in a single computer. They are based on phasor vectors and can answer almost all the questions of power system operators and designers except those involved with fast transients.
