This paper presents the results of an investigation into the subsynchronous resonance (SSR) instability of a single-cage induction motor supplied by a series capacitor compensated feeder. A great deal of insight into the mechanism of subsynchronous resonance instability is obtained from a simple equivalent circuit analysis and the discrete Fourier transforms (DFTs) of some of the transient waveforms.
