Abstract

This paper presents a method for designing a multi-machine power system stabilizer. The conventional design technique usinga single machine infinite bus approximation involves a frequency response estimation called GEP(s). Frequency responseis estimated between the input AVR and electrical output torque. The power system stabilizer is designed by frequencyresponse and based on the root locus method to improve the damping of oscillatory modes. By using this method, we canadjust the structure of the PSS compensator and its parameters in the multi-machine system and it does not need to knowthe equivalent reactance of output and voltage of the infinite bus or the other estimations in every machine. In the proposedmethod, information available at the high voltage bus of the step-up transformer is used to set up a modified Heffron-Phillipsmodel. Finally, this method is examined on three test systems. Simulation results indicate the performance and effectivenessof the proposed method.
