Title: Computing the internal transient voltage response of a transformer with a nonlinear core using gear`s method. Part 2: Verification

Abstract

An EHV transformer`s insulation structure must be designed to withstand the internal electrical stresses generated during system transients. Computer models are employed for predetermination of these stresses. Part 1 of this paper developed a detailed transformer model and solution method representing the nonlinear, saturable characteristic of the core during transients. The resulting set of stiff nonlinear differential algebraic equations (DAE`s) are solved by application of Gear`s method. Part 2 presents the verification of this methodology. This is accomplished by comparing the computed and measured response of a 765/345/34.5 kV 500MVA autotransformer during energization and transient excitation.
