Abstract

A transient stability index is described for the online security evaluation of electric power systems by providing a measure for their level of security. A technique for constructing this index is developed, applying the principles of pattern recognition and fuzzy sets theory while the stability determination is based on the initial fault-on accelerations of machine rotors. The analysis of two sample transmission systems is presented to illustrate the application of the developed index
