Transient simulation in real time
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 analogue to digital converters, as well as analogue signal amplifiers.The original, and at present still the main application in the market, is a simula tor 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 multipurpose 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.
