Abstract
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 multilimb 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. © 2008 IEEE.
