- Abstract
The validation of power system component models for transient analysis implies the use of data recorded from either field measurements or laboratory tests. This task can be particularly difficult when the transient process is quite nonlinear, as it occurs in ferroresonance phenomena. Up-to-date research has proved that the π<inline-graphic></inline-graphic> model can be more accurate than the classical T model for representing the transient response of transformers with a high level of saturation. This paper proposes a new technique for representing and implementing hysteresis in low-frequency transformer models using the π<inline-graphic></inline-graphic> approach. The ultimate goal is to validate the addition of hysteresis effects in the π<inline-graphic></inline-graphic> model for single-phase transformer representation in ferroresonance studies.
