Railway power equipment history management system and method based on fault location function

Abstract

The invention relates to a railway electric power equipment history management system based on fault location function and a method thereof. The system monitors an overhead line on-line through a dataacquisition unit, analyzes a real-time fault, returns to a foundation history database for storage through a data exchange bus, and corresponds to the actual data of the field overhead line one by one. Combined with the fault data to form the problem library, combined with the overhead line visual model, pushed to the patrol management mobile terminal, the terminal to the overhead line intelligent identification data association; the overhead line collects the fault information through the data acquisition unit, transmits the fault analysis background analysis by the aggregation unit, and then imports the results into the basic resume database. Combined with the data results of the positioning analysis module, the map positioning and navigation guidance are carried out through the map data module, and the site fault point is uniquely confirmed. The implementation of the invention can improve the accuracy of the intelligent judgment, reduce the manual patrol workload, and realize the ring-type data flow and fault comprehensive analysis and positioning of the overhead line facilities with the whole life cycle closed.

Description

technical field [0001] The invention relates to a power fault location system, in particular to a railway power equipment history management system and method based on the fault location function. Background technique [0002] Railway power overhead lines are an important part of the power system. The railway system grows into a large belt. The power overhead lines erected along the railway are not only large in number and variety, but also directly related to the stability and safety of power transmission, directly affecting the railway. normal operation. Railway power overhead lines are long and span many regions. Especially in the northwest of China, they often pass through uninhabited areas, deserts, Gobi and other sparsely populated areas. In this environment, a single power supply line fails, and it is difficult to find it in time. Even if it is found, it is very difficult It is difficult to accurately locate and carry out inspection and maintenance, often causing ser...

Problems solved by technology

Railway power overhead lines are long and span many regions. Especially in the northwest of China, they often pass through uninhabited areas, deserts, Gobi and other sparsely populated areas. In this environment, a single power supply line fails, and it is difficult to find it in time. Even if it is found, it is very difficult Difficult to accurately locate and carry out inspection and maintenance, often causing serious problems such as power outages, running production, and operation

[0003] Fault location of existing power overhead lines is not easy to install, poor positioning accuracy, high cost, etc. If you want to locate each pole, you need to install a detection device on each pole. If this is implemented on the entire railway line, the required quantity is huge. The cost is extremely high, and the later equipment installation, maintenance and maintenance will also increase a lot of unnecessary workload
