Abstract

This paper considers the use of a discrete supplementary control for transient stability enhancement of multimachine power systems. The principal advantage of the method presented in this paper is that off-line computations are used. This permits the application of the supplementary control of a 'multimachine' power system. The designation 'multimachine' is used in this context to denote systems of up to three machines; for practical systems containing more than three machines, appropriate model order reduction is suggested. Supplementary controls differ from primary controls in that they are only used during disturbances rather than continuously. Attention is focused on the insertion of braking resistors and a specially designed dynamic programming algorithm is described for optimal resistor switching. The switching strategy is computed off-line so that the on-line computational requirements are minimal.
