Abstract
A harmonic detection system (1) comprises a measurement component (71), a harmonic abnormality determination unit (561), and a smartphone (9). The measurement component (71) is installed at a specific position on a distribution line constituting a distribution network (100), and measures data related to the current of the distribution line. The harmonic abnormality determination unit (561) uses some or all of the data related to current as detection data to detect abnormality related to harmonics. The smartphone (9) is owned by a user (G), and notifies the user that an abnormality has occurred in the distribution line when a harmonic is detected.
Claims16
A harmonic detection system, comprising:
- a measurement component configured to be installed at a specific position on a power line constituting a distribution network, the measurement component measuring data related to current of the power line;
- a harmonic detector configured to use some or all of the data related to the current as detection data to detect a harmonic;
- a first transmitter configured to transmit a notification indicating that an abnormality has occurred in the power line when the harmonic is detected;
- a notification device configured to be owned by a user of power supplied by the power line, the notification device receiving the notification from the first transmitter and notifying the user that the abnormality has occurred in the power line when the harmonic is detected;
- and
- a storage unit configured to store data of the measurement component in association with data of the notification device;
- and
- a smart meter configured to detect an amount of power supplied to the power line,
- wherein the storage unit is configured to:
- store identification information of the measurement component in association with identification information unique to the smart meter configured to measure power of the power line on which the measurement component is installed, and
- store the identification information unique to the smart meter in association with the notification device of a user who owns the smart meter, and
- wherein when the harmonic is detected, the first transmitter is configured to transmit the notification to the notification device that is associated with the identification information of the measurement device measuring the current used in detecting the harmonic via the identification information unique to the smart meter in the storage unit.
