Title:
DISTRIBUTION NETWORK MONITORING SYSTEM
Document Type and Number:
Japanese Patent JP2019161858
Kind Code:
A
Abstract:
To provide a distribution network monitoring system that can accurately detect information on power usage.SOLUTION: A distribution network monitoring system 10 has LTLSs 7, a receiving unit 53a, and a correction unit 56. The LTLSs 7 have detection and power supply units 71, transmission units 76, and counter units 75e. The detection and power supply units 71 are installed at a plurality of predetermined positions of a power line provided in the distribution network 100 and perform electrical measurement of the power line by using a current flowing in the power line at the respective predetermined positions. The transmission units 76 transmit results of measurement performed by the detection and power supply units 71. The counter units 75e count the number of times of transmission performed by the transmission units 76. The receiving units 53a receive the transmitted measurement results and counter values. When there is a timing at which the measurement results are not received by the receiving units 53a, the correction units 56 perform correction on the measurement results on the basis of the counter values.SELECTED DRAWING: Figure 4
