This paper shows how additional insight into subsynchronous resonance of a series capacitive compensated turbogenerator power system can be obtained by a Fourier analysis of the time domain waveforms. These waveforms are generated by digital computer simulation of the IEEE bench mark model and then sampled, filtered and transformed into the frequency domain which shows up all the mechanical and electrical resonant modes. Different types of disturbances at different load values are used to evaluate their effect on the values of the resonant frequencies.
