Transients analysis of synchronous generator using the finite element technique

Abstract

The paper describes the use of the finite element technique when modeling electromagnetic transients in a power system in the time domain. The finite element matrices of electrical machines, have been obtained in natural (a, b, c) coordinates. The time integration has been performed using method. This paper presents a new method for power system analysis, based on the finite element technique. This method has been successfully applied on sudden short circuit synchronous generator analysis and voltage regulation of the generator under a sudden load. This method is competitive, even simpler, than well known nodal voltage method. The proposed method is suitable to the multimachine analysis, our main goal of research.
