The majority of transformer model realizations used for power system transient simulations have some significant deficiencies, particularly related to the transformer core implementation. They either do not include the multi-limb topology of the iron core, come upon some numerical stability issues, have limited use for three-phase transformers, or lack a complete leakage representation. Detailed consideration of the saturation effects is essential for accurate transient simulation of ferroresonance, excitation, inrush currents, half-cycle saturation, and similar phenomena. A recently published topologically-correct core model, valid for low- and mid-frequency ranges, addresses this need. This paper details the parameter estimation methods developed for the five-legged core of this model. ©2009 IEEE.
