Abstract
Turbine-generators have torsional natural frequencies due to physical properties of their long multi-element shafts. Series capacitor compensation in ac transmission networks has a tendency to reduce damping of torsional vibrations of nearby turbine generators. The phenomenon is called subsynchronous resonance (SSR), and it affects turbine-generators at subsynchronous frequencies that are specific to torsional oscillation modes of individual units. Series capacitors also have a tendency to amplify the shaft stress during major network transient events. The mechanism of the subsynchronous resonance is well understood. This paper first provides an overview of subsynchronous resonance (SSR) and the impact of series compensation on SSR, then other cases are mentioned other than series capacitor where it can also cause severe damages to machines and equipment. The paper also provides descriptions of technical methods for mitigating SSR problems. The subsynchronous resonance (SSR) for IEEE second benchmark system is simulated using Matlab based on the Power System Block-set in conjunction with Simulink. The effects of both series compensation level and fault clearing time on SSR are investigated. The results obtained verify the influence of both fault clearing time and series compensation level on maximum magnitudes of the turbine-generator shaft torques have been analysed using time domain simulation technique.
