Resumo

This article addresses issues of the structural and practical identifiability of a transient model of a synchronous generator. A structural identifiability analysis was conducted for nonlinear models of differential-algebraic equations (DAEs) and then applied to the DAE model of the synchronous generator, whose parameters were estimated by a practical identifiability analysis employing a trajectory sensitivity method. An optimal time window of measurement data was selected for improving the accuracy of the estimated parameters, which were validated from different sets of measurements collected in two different experiments.
