Abstract
In this paper, the authors first develop a simple noniterative equation representing the dynamic hysteresis phenomenon. Secondly, they delineate two successful methodologies for implementing the dynamic hysteresis model in real-time. The model was validated using a capacitor coupled voltage transformer (CCVT) and a magnetic type voltage transformer (VT) model obtained from measurements performed in IREQ's laboratories on real units. Tests on the models showed that the developed model handles successfully the dynamic behavior of the hysteresis. Comparison with simulator results proved that the model reproduced adequately the minor loops, Finally, tests from the high-power laboratory were compared successfully with those obtained from the real-time model.
