METHOD FOR DETECTING OPEN-CIRCUIT FAULTS IN ELECTRIC POWER DISTRIBUTION SYSTEM, AND POWER DISTRIBUTION FACILITIES MANAGEMENT SYSTEM

摘要

An open-circuit fault in an electric power distribution line is detected using metering devices each having a communication function and each placed on a power consumer's circuit connected to an electric power distribution system, and a location of the open circuit is identified. An electric power distribution facilities management system obtains, from the power distribution system to which are connected consumers each including a sensor provided with a communication function, meter-reading data within each of the sensors having a communication function, via a communication system. The system includes a number-of-unavailable-data calculation unit that calculates a number of unavailable meter-reading data from the sensors having a communication function, an on-fault number-of-unavailable-data calculation unit that calculates the number of sensors each having a communication function and each placed in the power distribution system, and a fault determining unit that determines whether an open-circuit fault is occurring in the power distribution system.
