Real Time Digital Simulator or RTDS as the abbreviation recommended by IEEE committee on real-time simulator applied for power systems provides
power system
An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The ...

High Voltage Alternating Current (HVAC) and
High Voltage Direct Current
A high-voltage direct current (HVDC) electric power transmission system (also called a power superhighway or an electrical superhighway) uses direct current (DC) for electric power transmission, in contrast with the more common alternating curren ...
(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
A natural disaster is "the negative impact following an actual occurrence of natural hazard in the event that it significantly harms a community". A natural disaster can cause loss of life or damage property, and typically leaves some econ ...
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.
