Abstract

The invention relates to a ring network power supply cable fault positioning system and method based on a cloud platform, belonging to the field of power monitoring. The system comprises a main control unit CPU board, a high-speed data acquisition unit DAU board, a cloud service platform, a GPS time service module, a 4G communication module and a power supply module; the high-speed data acquisition unit DAU board is used for acquiring high-frequency signals of a tested cable; the main control unit CPU board is used for receiving and processing the received high-frequency signals; the positionof the fault point is clearly indicated after the fault point distance is measured, and the fault point is marked. According to the method, the fault early warning prompt and data analysis processingcan be realized on the cloud platform, and the fault positioning information can be displayed.

Description

technical field [0001] The invention belongs to the field of electric power monitoring, and relates to a system and method for fault location of a ring network power supply cable based on a cloud platform. 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 current fault loc...
