Unbalanced transient-based finite-element modeling of large generators

Finite-element modeling is used to study the steady-state and transient performance of a large synchronous machine. In the present paper, we carry out a two-dimensional, non-linear, time-stepped finite-element simulation of a line-to-line short circuit on a large salient-pole synchronous generator with multiple rotor circuits under no-load conditions. The work is validated for performance prediction using a Hydro-Quebec network generator.
