Improve damping of subsynchronous Resonance oscillations using static synchronous series compensator equipped with supplementary damping controller

This paper presents the analysis and simulation of subsynchronous resonance (SSR) characteristics of a series compensated system with a static synchronous series compensator (SSSC) based on diode-clamped three level Converter as a part of the total compensation which is called hybrid series compensation (HSC).also, SSSC is used toenhance the stability of a Single Machine Infinite Bus (SMIB) . The effective damping can be achieved bysupplementary damping controller (SDC) is added to the SSSC. The detailed study of SSR is carried out based on eigenvalue analysis and transient simulation. The IEEE first benchmark model (FBM) is considered for the analysis
