Power system fault studies using finite element technique

Abstract

This paper proposes new and non-traditional approaches for power system fault calculations. The numerical algorithm is based on a finite element technique (FET) procedure. The finite element technique so far used for numerical analysis of continuum field problems here has been adapted to power system fault studies. The numerical procedure is very efficient, numerically stable and generally applicable. From the point of view of computational complexity and from the pedagogical point of view, novel computational method is very simple and suitable for the power system fault calculations. As the power system has been built assembling the three phase finite elements, the solution of the fault studies is natural and straightforward.
