Power transmission line distributed fault diagnosis system and method

Abstract

The invention discloses a distributed fault diagnosis system and method for a power transmission line. The distributed fault diagnosis system comprises a monitoring terminal, a front server and a central station server. The central station server comprises a communication micro-service unit, a core micro-service unit and a fault distance measurement micro-service unit; the front server receives the data message sent by the monitoring terminal and stores the data message in a database; the communication micro-service unit reads the data message from the database and forms a file; the core micro-service unit receives an interaction message sent by the communication micro-service unit, finds out a corresponding fault distance measurement micro-service unit based on ID information in the interaction message, and sends a file obtained from the communication micro-service unit to the fault distance measurement micro-service unit; and the fault distance measurement micro-service unit completes fault diagnosis based on the received file. According to the invention, the system access time of fault distance measurement terminals (namely fault distance measurement micro-service units) of different manufacturers can be greatly shortened, and the operation and maintenance efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power grid operation and maintenance, and in particular relates to a distributed fault diagnosis system and method for transmission lines. Background technique [0002] Overhead transmission lines have many points, long lines, wide areas, and complex network structures. They are distributed in the wild with harsh environments, causing great difficulties for equipment inspections. During actual operation, they often suffer from natural disasters (lightning strikes, rainstorms, Extremely bad weather such as heavy snow, strong wind, bird damage and other factors) and external damage (various constructions, traffic accidents, human-made theft, etc.), cause the grounding short circuit tripping of the line, or even the line is broken, causing the line to be paralyzed and causing a large area The power outages have brought certain impacts on the stability, safety, economy, efficiency and high-quality operation of ...

AI Technical Summary

Problems solved by technology

The excellent performance of distributed traveling waves in transmission line fault location has led to the rapid development of distributed traveling waves. There are many manufacturers of transmission line fault diagnosis and monitoring terminals, and the diagnostic and positioning function modules have been moved to the central station. The central station needs to have horizontal expansion capabilities. Simplify application deployment, and support the requirements of uninterrupted massive big data storage and analysis of original messages. The traditional architecture adopts a monolithic application architecture. Complex monolithic applications themselves are obstacles to continuous deployment. When resource conflicts exist between different modules, monolithic The application is difficult to coordinate and expand, which has a greater impact on its reliability and stability
