Verification of steady state model of power autotransformer

Abstract

This paper deals with the model of three-winding autotransformer for steady state analyses and for different types of step-voltage regulator. The paper is focused on comparison of two types of three winding transformer model and on verification of these models by means of measurement of distributing transformer. The analyzed transformer is installed and operated in the electric power station Stupava. Keywordsmathematical model of three-winding autotransformer, step-voltage regulators
