- Abstract
Subsynchronous Resonance (SSR) oscillations in a power system are most unwanted phenomenon. The interaction between torsional system and electrical system exhibits a situation of SSR oscillations. These oscillations, if not sufficiently damped, grow tremendously, leading to stability problem. Though Power System Stabilizer (PSS) damps subsynchronous oscillations effectively over the period of time, still oscillations due to SSR remain a challenge to it. Flexible AC Transmission System (FACTS)- based compensators play an important role in mitigating SSR oscillations most comprehensively. The paper proposes a fuzzy tuned Static VAR Compensator (SVC) for analyzing the SSR phenomenon in an IEEE Second Benchmark Multimass (ISBM) system. An ISBM model with SVC is carefully designed using Fuzzy Logic Damping Controller (FLDC) for SSR analysis using MATLAB/Simulink. The simulated results showed higher convergence rate and better SSR damping capability.
