20150066403 | LOSS CALCULATION METHOD AND LOSS CALCULATING DEVICE - A first calculating unit calculates a load current of each distribution facility based on a sending voltage in a power source facility and load information on power consumption facilities in an electrical circuit including the power source facility, the distribution facilities, and the power consumption facilities connected to one another to form the electrical circuit. A second calculating unit calculates the amount of power loss in each distribution facility based on the calculated load current of each distribution facility. | 03-05-2015 |
20150097574 | PHASE DETERMINING METHOD, PHASE DETERMINING APPARATUS, AND RECORDING MEDIUM - A non-transitory computer-readable recording medium stores therein a program that causes a computer to execute a phase determining process. The phase determining process includes: transmitting electricity to a consumer via a power distribution line branched from a power distribution line using a three-phase three-wire system; identifying a time change pattern of a highest correlation with a time change pattern of power consumption, voltage, or current at the consumer out of time change patterns of power consumption, voltage, or current of respective phases of a high-voltage power distribution line using the three-phase three-wire system; and determining a phase corresponding to the identified time change pattern to be a phase at a time of branching the power distribution line to the consumer. | 04-09-2015 |
20150100256 | IMBALANCE DETERMINING METHOD, IMBALANCE DETERMINING APPARATUS, AND RECORDING MEDIUM - A non-transitory computer-readable recording medium has stored therein a program that causes a computer to execute an imbalance determining process. The imbalance determining process includes: analyzing fluctuation situations of voltage values of respective phases in a power distribution line using a three-phase three-wire system; determining whether a location at which degree of divergence in voltage values among the phases exceeds a predetermined criterion is present; and outputting a result of the determining. | 04-09-2015 |
20150120227 | FACILITY SELECTION SUPPORTING METHOD AND FACILITY SELECTION SUPPORTING DEVICE - A facility selection supporting device calculates a total current value of consumers located in and after a certain power supply section on the way from a distribution substation to a particular consumer and outputs a recommended distribution facility for the power supply section based on the calculated total current value. | 04-30-2015 |
20150200542 | POWER DISTRIBUTION MANAGEMENT APPARATUS, POWER DISTRIBUTION MANAGEMENT METHOD, AND RECORDING MEDIUM - A power distribution management apparatus includes an electrical connection storage unit, a search unit, and an output unit. The electrical connection storage unit is configured to store electrical connection information in which a combination of a plurality of junctions that describes which a plurality of facilities of a power distribution system are electrically connected to each other and a facility determined based on the combination are associated. The search unit is configured to search a facility corresponding to the combination while investigating an uninvestigated junction among the plurality of junctions contained in the combination starting from a predetermined junction with reference to the electrical connection information stored in the electrical connection storage unit. The output unit is configured to output facility information obtained from the combination where the investigation is performed and a result of the search after the investigation and the search are performed. | 07-16-2015 |
