Series capacitor compensation in AC transmission systems may cause sub synchronous resonance that can lend to turbine generator shaft failure. Series capacities also have a tendency to amplify the shaft stress during major network transient events. When the level of series compensation is increased sub synchronous Resonance will be more. The mode of oscillation between the electrical and mechanical system will be high. The major concern of sub synchronous resonance is self-excitation and Transient Toque amplification. This paper is mainly emphasized on analysis of Sub-Synchronous Resonance (SSR) and mitigation using SSSC (Static Synchronous Series Compensator). The mechanical turbine generator and electrical network system are based on FBM. A Simulation with FBM to study SSR is implemented using MATLAB. The SSSC is used as a countermeasure, and it is applied to system to damp out the SSR. Results are validated by simulation.
