1. A power distribution management apparatus comprising:
- an electrical connection storage unit configured to store electrical connection information in which a combination of junctions at which a plurality of facilities included in a power distribution system are electrically connected to each other and a facility determined by the combination of the junctions are associated, the facility being a branch that connects a junction to another junction constituting the combination of the junctions,an acquisition unit configured to acquire a first junction corresponding to a first facility from which predetermined data is acquired within a predetermined interval and a second junction corresponding to a second facility from which the predetermined data is not acquired within the predetermined interval; and
a detection unit configured to firstly detect, as normal items, junctions located between the first junction and a power-supplying facility of a power distribution system, secondly detect, as abnormal items, junctions other than junctions detected at the first detecting as the normal items among junctions located between the second junction and the power-supplying facility of the power distribution system, and specify an abnormal item of the power distribution system in a narrower range than a section partitioned by switches without limiting an abnormality detection target to a high-voltage system and limiting an abnormality detection range to a unit of an open/close division.

Abstract
A power distribution management apparatus includes an acquisition unit and a detection unit. The acquisition unit is configured to acquire predetermined data at a predetermined interval from meters classified into a predetermined group, the data containing power consumption. The detection unit is configured to detect, as an abnormal place, a facility of a power distribution system associated with the group when the predetermined data is not acquired within the predetermined interval from the respective meters included in the group.

6. An abnormality detection method which is executed by a computer,
wherein the method causes the computer to perform storing electrical connection information in which a combination of junctions at which a plurality of facilities included in a power distribution system are electrically connected to each other and a facility determined by the combination of the junctions are associated, the facility being a branch that connects a junction to another junction constituting the combination of the junctions, acquiring a first junction corresponding to a first facility from which predetermined data is acquired within a predetermined interval and a second junction corresponding to a second facility from which the predetermined data is not acquired within the predetermined interval; - and
first detecting, as normal items, junctions located between the first junction and a power-supplying facility of a power distribution system, second detecting, as abnormal items, junctions other than junctions detected at the first detecting as the normal items among junctions located between the second junction and the power-supplying facility of the power distribution system, and specifying an abnormal item of the power distribution system in a narrower range than a section partitioned by switches without limiting an abnormality detection target to a high-voltage system and limiting an abnormality detection range to a unit of an open/close division. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory computer-readable recording medium having stored therein a program for abnormality detection for causing a computer to execute a process comprising:
-
storing electrical connection information in which a combination of junctions at which a plurality of facilities included in a power distribution system are electrically connected to each other and a facility determined by the combination of the junctions are associated, the facility being a branch that connects a junction to another junction constituting the combination of the junctions, acquiring a first junction corresponding to a first facility from which predetermined data is acquired within a predetermined interval and a second junction corresponding to a second facility from which the predetermined data is not acquired within the predetermined interval; and first detecting, as normal items, junctions located between the first junction and a power-supplying facility of a power distribution system, second detecting, as abnormal items, junctions other than junctions detected at the first detecting as the normal items among junctions located between the second junction and the power-supplying facility of the power distribution system, and specifying an abnormal item of the power distribution system in a narrower range than a section partitioned by switches without limiting an abnormality detection target to a high-voltage system and limiting an abnormality detection range to a unit of an open/close division. - View Dependent Claims (12)
