Electrical fault location determination in a distribution system based on phasor information

A method, comprising:

• receiving, by a device comprising a processor, first phasor information from a single first phasor measurement unit device in response to detecting a fault event for an electrical energy distribution system, wherein the fault event comprises a fault that is a phase-to-ground fault;
• receiving, by the device, electrical distribution system information comprising parameters related to the electrical energy distribution system comprising at least two different energy distribution pathways;
• determining, by the device, fault location information comprising at least one possible fault location on at least one of the at least two different energy distribution pathways based on the phasor information and the electrical distribution system information;
• determining a probable fault location from the at least one possible fault location of the fault location information based on second phasor information from a single second phasor measurement unit device, wherein the probable fault location is more likely to be a true fault location than another possible fault location of the at least one probable fault location;
• and
• initiating deployment of repair resources that cause a repair to the fault in response to the fault event of the electrical energy distribution system based on the probable fault location comprised in the fault location information.

A computer readable storage device comprising executable instructions that, in response to execution, cause a device comprising a processor to perform operations, comprising:

• receiving first phasor information related to determining a first candidate location of a fault on a first energy distribution path in an electrical energy distribution system comprising at least a second energy distribution path that is a different path than the first energy distribution path, wherein the first phasor information is for a determined time from a first phasor measurement unit device, wherein the fault comprises an unintended phase-to-ground electrical pathway;
• receiving second phasor information related to determining a second candidate location of the fault in the electrical energy distribution system, wherein the second phasor information is for the determined time from a second phasor measurement unit device;
• receiving electrical distribution system information related the electrical energy distribution system, wherein the electrical distribution system information comprises a model of at least a portion of the electrical energy distribution system for the determined time;
• determining a fault location information set comprising fault information related to the fault based on the first phasor information and the electrical distribution system information;
• determining a subset of the fault location information set based on validating the fault by employing the second phasor information and the electrical distribution system information, wherein the validating removes an invalid fault location of the fault location information set;
• causing a repair of the fault to be performed via dispatch of a repair resource in response to the fault in the electrical energy distribution system based on the subset of the fault location information set;
• and
• facilitating access to the fault information of the subset.
