The benchmark model for the study of Subsynchronous resonance is presented by IEEE Subsynchronous Resonance task force. Here, the IEEE First Benchmark system for Subsynchronous resonance is simulated using MATLAB for comparison. The oscillations due to SSR are observed between turbine-generator and between various turbine shafts. This paper mainly focuses on the use of highly versatile software MATLAB for analysis of Subsynchronous Resonance in power systems.
