Abstract

This paper describes the application of a realistic proposed control strategy with feedback excitation together with those of conventional power system stabiliser (P.S.S.) and linear optimal control (L.O.C.). Digital simulation results have been obtained using a single machine infinite bus power system dynamic model. The results presented in this paper show that the application of the proposed technique leads to accurate solution, utilising a considerable computer time and less core requirement w.r.t. P.S.S and L.O.C. techniques.
