Small-Signal Stability Analysis of Distorted Power Systems installed with SSSC

M. Ladjavardi, Mohammad A. S. Masoum, Syed Islam

Abstract

Time and space harmonics can cause variations on synchronous generator steady state operating conditions and the small-signal stability of power system. Static synchronous series compensator (SSSC) is a FACTS device which is widely used in transmission lines. In this paper eigen-value analysis method is used to investigate the impact of time and space harmonics on small signal stability of single machine infinite bus (SMIB) system installed with SSSC. System state space equations are calculated considering additional terms due to the presence of harmonics. Simulation results are demonstrated for different harmonic levels and show the considerable impact of harmonics on the system eigen-values and hence dynamic behavior of the system.
