THE DESIGN OF STABILIZER FOR SHAHID RAJAEI STEAM POWER PLANT BY V.S.S. METHOD

Application of adaptive P.S.S. for improving the dynamic stability of power system has received considerable attention during last decade. A simplified linear model for synchronous machine connected to an infinite busbar model is used to test the P.S.S.. In this paper a new approach for Power system stabilization is proposed based on the powerful theory of Variable Stracture Systems (V.S.S.). Simulation results obtained for Shahid Rajaei Steam Power Plant, under the ide range of parameter variations.
