Integral equation method for electromagnetic modeling of the electrical substation

Abstract

This paper presents an integral method in order to model the structure with thin conductive and magnetic regions and electric circuit system. The electric sytem is descried by the equation circuit, while shell element formulation is used for thin regions. The interaction between thin regions and electric circuit system is presented. The proposed method facilitates modelling conductors with complex shapes and various skin effects across thickness of the shell taken into account. A real power station is modeled by using the integral equation system. In addition, the results compared with the finite element method also prove the accuracy and great potential of this integral method.
