Simulation and Application of Power System Stabilizer on Power SystemTransient Stability

摘要

This paper introduces the working principle and the mathematical model of additional power system excitationcontrol-Power System Stabilizer (PSS). Through established a typical single machine-infinite bus power system simulationmodel, we simulate the synchronous generator’s transient operational characteristics following a severe disturbance.The simulation results show that the PSS can not only effectively increase the system damping, but also improve operationalcharacteristics of the generator, considerably enhance power system dynamic and transient stability.
