Improving Transient Stability by Use of Dynamic Braking

Results of studies for the application of decelerating resistors for improving transient stability on the Arizona Public Service Company 292-mile transmission system from the Four Corners Plant to Phoenix are presented and analyzed. These studies indicate the feasibility of the use of decelerating resistors for overcoming cases of transient stability at a minimum cost. To the authors' knowledge, this is the first investigation of this application in the design of a system.
