Abstract

This paper scrutinized the damping effects of installing the prototype PSSs by a transient analysis for eight buses of faults in the South Korean power system. The PSSs used have the ω-PSS blocks for IEEEST model with a single input and the ω+power PSS blocks for PSS2A model with dual inputs. The simulation tool was a TSAT (Transient Security Assessment Tool) developed by Powertech Labs Inc. The voltages of the transmission line for simulations were 765㎸ and 345㎸, and the faults for eight cases were sequenced by considering the open state and the close state of the lines. In the simulations, the three-phase line to ground (L-G) fault generated different points for each region. The simulations were compared to the cases of no PSS, partial IEEEST and PSS2A, absolute IEEEST, and absolute PSS2A to show that the power system oscillation can be effectively damped by PSS modules. Simulations were conducted to confirm the effectiveness for the KEPCO (Korea Electric Power Corporation) power system.
