Abstract

Low frequency oscillations have been observed in KEPCO system. This paper represents how to analyze the power system by using the AESOPS program and analyze the various factors affecting the damping characteristics of these oscillations in KEPCO system of 1986. The characteristics of load, the amount of power flow on the transmission line and the gain of exciter have a significant effects on the damping of the system while the governing system has only a minor one. With the Power System Stabilizers, the stability of the power system has been increased.
