  • Coordination of protective elements in an electric power system
    Patent number: 11962140
    Abstract: The present disclosure relates to systems and methods to coordinate protective elements in an electric power system (EPS). In one embodiment, a system may include a Time vs Normalized Impedance Length subsystem to determine a first plurality of times of operation of a first protective element for a plurality of fault locations in the EPS and to determine a second plurality of times of operation of a second protective element for the plurality of fault locations in the EPS. A protective action subsystem may coordinate a response of the first protective element and the second protective element. The protective action subsystem may establish a pickup and a protective action for the second protective element. Upon detection of a fault in the EPS, one of the first protective action and the second protective action may be implemented based on one of the first pickup and the second pickup.
