Abstract

The invention discloses a ring network cable early fault early warning and positioning system and method based on transient disturbance. The system comprises a central processing unit. According to the looped network cable early fault early warning and positioning system and method based on transient disturbance, through arrangement of the monitoring unit, it is ensured that the fault of the looped network cable is accurately monitored, the working connectivity of the cable is ensured, and bad influences on a user due to power failure are avoided; by arranging the fault positioning unit, multiple types of fault points can be quickly found and positioned, so that related maintenance personnel can be informed to go to repair, the positioning is accurate, the automation degree is high, and the daily monitoring and maintenance of power cables by workers are facilitated; by arranging the maintainer login unit and the management operation unit to evaluate the ability of maintainers, the working enthusiasm among the maintainers is improved, the fault removal speed is increased, and the effect of removing faults at the highest speed is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to an early warning and positioning system and method for ring network cables based on transient disturbances. Background technique [0002] With the development of automation technology, the automatic operation of distribution network has become more and more important. Distribution network automation refers to the use of various technologies and distribution equipment to monitor and manage the distribution network, so that the distribution network is in a safe, reliable, high-quality, economical and efficient operating state. Fault location is one of the key technologies of distribution automation. It requires the ability to quickly locate the fault point when a fault occurs, and notify the maintenance personnel of the power department in time to save time for the maintenance personnel of the power department to troubleshoot faults and restore power supply. The ...
