Phase shift of the current under a single-phase short-circuit in the stator w…

An equivalent model of a faulty turbogenerator under a single-phase short-circuit in the stator winding is presented. The model is based on modified voltage–current equations for the positive-sequence component of the shortcircuit current that takes into account the mutual spatial displacement of particular part of the faulty stator winding, the rotor magnetic asymmetry and the impact of the…
