The Development of New Adaptive PSS System for Automatic Parametric Modeling Techniques of Power System Oscillation Waveforms

Abstract

In Japan, since the development of large power system, there have been spontaneouse low-frequency oscillation and local mode oscillation. The conventional PSS has been applied to generators in trank power system as a measure to improve the damping power oscillation. However, it is difficult for this PSS to improve the damping power system oscillation because of the hardware and the design of fixed PSS control constants. It has therefore become necessary to develop a new adaptive PSS system. This paper explains the development of new adaptive PSS system and the simulation of low-frequency and local mode oscillation for this new PSS system.
