A distributed fault diagnosis system and method for transmission lines

Abstract

The invention discloses a distributed fault diagnosis system and method for transmission lines. The distributed fault diagnosis system includes a monitoring terminal, a front server and a central station server. The central station server includes a communication microservice unit, a core microservice unit and a fault distance measurement microservice unit; the front-end server receives the data message sent by the monitoring terminal and stores it in the database; the communication microservice unit reads the data message from the database document and form a file; the core microservice unit receives the interaction message sent by the communication microservice unit, finds out the corresponding fault location microservice unit based on the ID information in the interaction message, and obtains from the communication microservice unit The file sent to the fault distance measurement microservice unit; the fault distance measurement microservice unit completes the fault diagnosis based on the received file. The invention can greatly shorten the access time of fault distance measuring terminals (that is, fault distance measuring micro service units) of different manufacturers to the system, and improve the efficiency of operation and maintenance.

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
