ACCIDENT SECTION DETERMINATION DEVICE AND SYSTEM IN DENDRITIC DISTRIBUTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To determine an accident section from accident direction data considering sensor abnormality in a distribution system.

SOLUTION: An accident section determination system comprises: a dendritic distribution system connected to a transformer station switch; a plurality of switches which are allocated in various places in the dendritic distribution system and divides the distribution system into appropriate sections; a communication network connected to the switches; and an accident section determination device connected to the communication network. The accident section determination device has: first processing which obtains an accident direction at each installed position of the plurality of switches in the case of accident occurrence in the dendritic distribution system, and modifies an accident direction detected by a switch whose abnormality is identified by determining consistency among a plurality of accident directions of the plurality of switches in the dendritic distribution system; and second processing which determines an accident section by using the plurality of accident directions of the plurality of switches in the dendritic distribution system including the accident direction modified in the first processing.
