Abstract:
Protection of an electrical generator includes determining a rotor and stator components using rotor and stator electrical signals, calculating a unbalance and/or differential component using the stator and rotor components, and determining a stator or rotor fault based on the unbalance and/or differential component. Further, the faulted phase and/or zone of a stator fault may be determined using the stator positive sequence voltage and negative sequence current.
