Title: Phase rotation as a means of augmenting transient stability

Abstract

As turbine generators become larger, their per-unit inertias decrease and their transient reactances increase. The result is reduced transient stability which must be augmented by supplementary techniques of transient stability enhancement. 120/sup 0/ phase rotation with immediate fast valving is shown to be a very effective means of augmenting transient stability when controlled by generator rotor angle. Variations, involving delay of fast valving or 360/sup 0/ phase rotation or multiple 120/sup 0/ phase rotation, are also studied. Comparisons, between these methods of augmenting transient stability, are made on the basis of transient stability enhancement and torsional shaft stress characteristics.
