Abstract

Power system stabilizers (PSS) have been studied for many years as a method to increase power system stability. This paper is focused on the tuning and structure of the PSS. The generator control system is introduced to illustrate the working environment of the PSS. The mathematic model of the generator, automatic voltage regulator (AVR) and PSS are analyzed, and the system transfer function in presence of the PSS is derived. Base on the transfer function, a new tuning method is introduced which does not require all the system parameters. It is an experiment based tuning method of which frequency response tests are at the core. The feasibility of this tuning method is illustrated and verified for the real power system in the power control lab of the PCS2000 Company. Our experiments show that after tuning, system damping is increased and the oscillation is reduced which proves the effectiveness of our PSS tuning method. © 2012 IEEE.
