Distribution wire fault online monitoring method and terminal equipment

Abstract

The invention is applicable to the technical field of power supply,and provides a distribution wire fault online monitoring method and terminal equipment. The method comprises the steps that distribution wire work attribute information sent by a plurality of acquisition devices is received,wherein the distribution wire work attribute information comprises voltage,current and position information of a plurality of collection points of a distribution wire; then the voltage of a target collection point is compared with a preset voltage standard threshold,the current is compared with a preset current standard threshold,and whether the distribution wire of the target collection point has a fault or not is judged,wherein the target collection point is any one of the collection points; finally,the position information of the target collection point is sent to a maintenance terminal if it is judged that the distribution wire of the target collection point has the fault. The troubleshooting range can be reduced,the fault position of the distribution wire can be quickly located,and the maintenance processing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to an on-line fault monitoring method of distribution lines and terminal equipment. Background technique [0002] The distribution network is the terminal network of the power system, which directly contacts and supplies and distributes electric energy to users. The reliability of the distribution network is a concentrated projection of the structure and operating characteristics of the entire power system, which directly affects the quality of power supply to users. Due to the long transmission distance of the distribution line of the distribution network, the complex terrain along the way, and the harsh environmental and climatic conditions, it is easy to cause line faults such as short circuit, open circuit or grounding. normal production. [0003] At present, the traditional method for identifying distribution line faults mainly relies on complaints from users ...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the embodiment of the present invention provides an online monitoring method and terminal equipment for distribution line faults, so as to solve the existing technology which mainly relies on users’ complaints about power outages, tripping or voltage instability, etc., but the transmission distance of distribution lines It is far away and the branches are complicated. After a fault occurs, it is not easy to determine the fault point, resulting in too large a scope of investigation and technical problems in the maintenance process.
