Abstract

This chapter describes performance of the power system stabilizer (PSS) of a large thermal power plant as tuned by the manufacturer. The stabilizer was redesigned based on extended phase compensation of the exciter input-the electrical torque transfer function and root locus analysis; and its effect on local, interplant, and interarea electromechanical oscillations was thoroughly analyzed. Participation factors and mode shapes were effectively employed to identify local, interplant, and interarea modes, as well as their characteristics. The PSS designed with extended phase compensation improves the damping of local and interplant oscillation modes considerably, and has some positive damping effect on interarea oscillations. Fine-tuning during onsite tests was necessary to achieve satisfactory performance. P-f PSS slightly outperforms P-w PSS in damping electromechanical oscillations. As Bistoun PSS has a special structure with two inputs, frequency, and power, its performance is compared with power-speed PSS. The effect of PSS with existing and new tunings on transient stability is studied.
