AN ADVANCED AND POWERFUL REAL-TIME DIGITAL TRANSIENT NETWORK ANALYZER

A few years ago, the study and simulation of fast phenomena in real-ti me, was the private ground of analog simulators, But the limitation in modeling, the complexity and the costly maintenance of these simulato rs was a brake upon their development and made their profitability unc ertain. The test of power system equipment such as controls, relays or power electronic devices needed a new type of simulator, much more ve rsatile and cost-efficient than their predecessors: the real-time Digi tal Transient Network Analysers (DTNA), Until a few months ago, the de sign of DTNA's was based on dedicated technologies, Today, the ever in creasing calculation power has now reached a level that allows realtim e simulations of fast phenomena to be carried on standard computers. W e present in this paper a new and fully digital TNA that relies on a s tandard computer.
