DYNA-TEST simulator for relay testing. II. Performance evaluation

For pt.I see ibid., vol.6, no.4, p.1427 (1991). Evaluation steps undertaken in the analysis of the DYNA-TEST simulator performance are described. The evaluation assumes comparison of the simulator output waveforms obtained using simulated data with the reference waveforms obtained through recording of an actual fault event. Tests are done using specific utility data. Particular attention is given to the system and instrument transformer modeling as well as to the D/A (digital-to-analog) conversion signal reconstruction subsystem characteristics. Particular reference is made to the Houston Lighting and Power (HL&P) system modeling approach.<
