An accurate software model for off-line assessment of a digital relay
A software model of a digital power system protection relay is added to an offline emtp (EMTDC) and is then subjected to the same waveforms as the actual relay. Its performance is measured against the performance of the actual relay and the accuracy of the model is assessed.
