Torsional oscillations of the turbine-generator due to network faults

A model of the electromechanical system, suitable for the analysis of torsional oscillations due to the power system’s faults, is established. Results of an example of computer simulation of transient torsional torques in the shaft-line due to a three-phase fault and the subsequent fault clearing, as obtained by the model, are presented. Effect of chosen fault clearing time is discussed.
