This paper presents a power system stabilizer (PSS) using adaptive control rules. The PSS consists of an adaptive controller and a compensator to damp the oscillations of power system. The function of controller is to supply an adaptive control signal to the exciter or governor with the adaptive law, which can damp most of the power system’s oscillations.
The function of compensator is to delete the extra disturbance or uncertainty. The principle and equation derivation are introduced and analyzed. Simulations for the power system are demonstrated their performance and compare with the conventional PSS does.
