Abstract:
A method for controlling a power distribution network includes receiving, via an electronic processor, a fault indication associated with a fault from a first isolation device of a plurality of isolation devices. The processor identifies a first subset of a plurality of phases associated with the fault indication and a second subset not associated with the fault indication. The processor sends a first open command to each member of a set of downstream isolation devices for each phase in the first subset. The processor identifies a plurality of tie-in isolation devices to be closed to restore power. Responsive to identifying a first potential loop configuration, for each of the plurality of tie-in devices, the processor sends a close command to the tie-in isolation device for each of the plurality of phases and sends a second open command to the associated downstream isolation device for each phase in the second subset.
