- Abstract
Subsynchronous resonance (SSR) oscillations is a problem of great interest in the industry. SSR causes torsional oscillations with ever-increasing amplitudes occurring in the machine shaft sections resulting in a significant premature loss of fatigue life of the shaft metal with the consequent irrevocable fatigue cracks or even a shaft fracture. The main objective of this article is to implement a modern dynamic braking resistor model, namely rectifier controlled braking resistor, controlled via fuzzy logic controller for tempering SSR oscillations. The proposed scheme is authenticated in this work using the wellknown IEEE second benchmark model via MATLAB/Simulink-based modeling and simulation environment. Comparative simulation study of the test system with and without the proposed scheme should demonstrate its effectuality for mitigation of SSR oscillations.
