Abstract :
Two unbalanced faults (line-to-neutral and line-to-line short-circuits) in a synchronous machine are simulated by the finite element method (FEM). In order to accomplish these tasks, the FEM had to be associated with the moving-airband technique as well as the coupling with electric circuit. Results obtained in the simulations concerning the armature current and torque are compared with analytical curves
