Advances in digital parallel processing, combined with the ability of power systems to be processed by means of subsystems, provides the basis for real-time transient simulation. Simulation in real-time permits realistic testing of the behaviour of control and protection systems. This requires the addition of digital-to-analogue and analogueto-digital converters, as well as analogue signal amplifiers. The original, and at present still the dominant product on the market for the simulation of electrical power systems, is a simulator based on dedicated architecture called RTDS (Real-Time Digital Simulator). This unit practically replaced all the scale-down physical simulators and can potentially represent any size system. The development of multi-purpose parallel computing is now providing the basis for real-time simulation using standard computers instead of dedicated architectures and should eventually provide a more economical solution.
