Small Signal Stability Analysis of Six-phase Synchronous Generator

In the present work, a higher order linearized model has been developed to assess the small signal excursion characteristics of an asymmetrical six-phase synchronous generator system connected to infinite bus using eigenvalue criterion. The stability of the system under small perturbation of different variables has been examined from the placement of eigenvalues. The work establishes an association between generator and loading parameters with pair of eigenvalues, thus the system stability. Further a participation factor analysis has also been carried out to identify the effect of dynamic state variable on a given mode or eigenvalue.
