Application of power system stabilizer to enhance dynamic performance of Siahbisheh pumped-storage power plant in Iran

Abstract

It is the purpose of this paper to investigate the design of a stabilizer via sampling the speed and voltage feedback in order to improve the oscillations of generators in Siahbisheh pumped-storage power plant in Iran. An overall PSS is utilized for all of the generators and its output is connected separately to the generators excitation systems. Moreover, a terminal voltage feedback is employed for damping oscillations. Comparing the simulation results shows a considerable improvement in the oscillations of the rotor speed, generator power, and terminal voltage. The proposed method is feasible and cost effective.
