Abstract: In this paper, a discrete time power system stabilizer is designed for silent-pole synchronous generator connected to infinite bus. In this study, the synchronous generator is represented by simplified transient model in qd rotating reference frame. In simplified model both the damper windings and changing in flux linkages are neglected during transient period. The rise of electricity demand in a power system and the widely spread of networked control systems require the use of discrete-time devices. Digital devices are widely spread and play an essential task in the operation and control of power systems. Several kinds of digital controlled devices have been put into practical use in power systems for the last decade, such as power system stabilizers PSS, proportional-integral plus derivative PID controllers and automatic voltage regulators AVR.The power system stabilizer is represented by a three-pole three-zero, lead-lag type PSS. The effects of sampling time and PSS parameters are simulated and examined. TRUETIME simulink library is used to implement the discrete PSS through networked control system.
