摘要 |
PROBLEM TO BE SOLVED: To detect a disconnection fault of a distribution line by using an Advanced Meter Infrastructure (AMI) with a telecommunication function installed at a power consumer who is connected to a distribution system to specify a disconnected location.SOLUTION: A distribution facility management system for obtaining meter information of a sensor with a telecommunication function via a communication system from a distribution system connected to a user who has installed the sensor with a telecommunication function comprises a deficient number calculation part for calculating the number of missing piece of the meter information obtained from the sensor with a telecommunication function; a deficient number at disconnection calculation part for calculating the number of the sensor with a telecommunication function of the distribution system installed; and a disconnection determination part for determining disconnection of the distribution system by comparing the installation number of the deficient number at disconnection calculation part and the number of missing piece of the meter information. |
