Abstract

This paper presents a new adaptive Power System Stabiliser (PSS) designed in the frequency domain, which has been developed and implemented in the laboratory using a multi-transputer system. This stabiliser tracks the variations of operating conditions and system configurations of power systems by estimating the oscillations occurring in the systems, and adjusts its parameters on-line to supply required damping to suppress the oscillations. Nonlinear simulations of an unstable power system and experimental results on a laboratory model power system show that this adaptive PSS possesses good robustness to changes of the operating conditions and system configurations, and can considerably improve the system stability.
