Transient stability analysis for symmetrical and unsymmetrical faults in mixed three-phase and six-phase power systems
1989
Abstract The aim of this paper is to analyse the transient stability of a three-phase power system with six-phase lines interconnected by three-phase to six-phase transformers. For these mixed power systems a transient stability analysis is performed under all main types of disturbances (short-circuits, generator and load rejection, line outages), particularly in the case of faults at six-phase buses. A generalized procedure to evaluate transient stability is explained in detail. It is based on the symmetrical components method, which allows one to consider also unsymmetrical faults both at three-phase and six-phase buses. For every possible unsymmetrical short-circuit an equivalent fault a…
Charles LeGeyt Fortescue and the method of symmetrical components
2002
The author gives a brief review of the life and work of Charles LeGeyt Fortescue with particular reference to his 1918 paper on the "Method of Symmetrical Co-Ordinates Applied to the Solution of Polyphase Networks" which grew out of his investigations of problems related to railway electrification, which began in 1913. As a postlude to the author's article, the paper presents Fortescue's own writing on the topic of symmetrical components, which he included in a document he produced on 8 October 1934, titled "High Points in My Career".
