Static synchronous series compensator (SSSC) has the ability to emulate a reactance in series with the connected transmission line. When fed with some supplementary signals from the connected system, SSSC is able to participate in the power system inter-area oscillation damping by changing the compensated reactance. This paper analyses the influence of SSSC on power system small signal stability. A SSSC damping controller scheme is presented and discussed. In DIgSILENT PowerFactory software, modal analysis and time-domain simulation are conducted in a single-machine infinite bus system model and a four-machine two-area test system model to verify and improve the damping controller scheme.
