When a steam Turbine-Generator is connected to a series compensated long transmission line, an adverse phenomenon namely Sub-Synchronous Resonance (SSR) may occur. The main purpose of this work is to verify the capability of the Distributed Static Series Compensator (DSSC) as a member of D-FACTS family in mitigating the SSR. Two novel controllers as: the Particle Swarm Optimization (PSO)-based Conventional Damping Controller (CDC) and the Fuzzy Logic Based Damping Controller (FLBDC) are designed and implemented in traditional controller of the DSSC in order to provide the effective damping. The system stability is studied through time domain simulations, Fast Fourier Transform (FFT) analysis, and a Performance Index (PI) which is defined based on the dynamics of the power system. Simulation results are carried out with MATLAB/Simulink on the IEEE Second Benchmark Model (SBM) aggregated with the DSSC modules. Three various cases of study are considered in order to compare the operation of the proposed FLBDC with the PSO based CDC in different transient states.
