Development of a new adaptive PSS system for automatic parametric modeling techniques for power system oscillation waveforms

摘要

In Japan, since the development of large power systems, there have been spontaneous low-frequency oscillation and local mode oscillation. The conventional PSS has been applied to generators in a trunk 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 a new adaptive PSS system and the simulation of low-frequency and local mode oscillation for this new PSS system.
