Power System Transient Stability Analysis Using Hybrid Model Based on the Finite Element Method

Abstract

This paper presents a simple, but very powerful, numerical algorithm for the power system transient stability simulation. The aim of this paper is to fill the gap between the Transient Stability Programs (TSP) and the Electromagnetic Transient Programs (EMTP) by developing a new simulation tool based on the finite element (FE) representation of the power system element. The proposed hybrid model based on the Finite Element Method (FEM) allows us to avoid disadvantages of TSP comparing to EMTP that leads to the simulation of the electromechanical transients in a more accurate and efficient way. In order to show the principles of the proposed method in details, the proposed numerical method has been tested and compared to the solutions obtained by the well known and established EMTP simulation tool where a very good correlation has been demonstrated.
