Embodiment 1

[0035] In this embodiment, a distribution line fault location system is provided, figure 1 is a structural block diagram of a distribution line fault location system according to an embodiment of the present invention, such as figure 1 As shown, the distribution line fault location system includes: a fault location device FLD11 for collecting fault recording data of each distribution line; a data acquisition and monitoring control SCADA server 12 in the distribution master station system for receiving faults Wave recording data, and analyze the fault recording data, and locate the fault line from multiple distribution lines.

[0036] Through the above distribution line fault location system, the fault recording data is collected by the distribution line fault location device FLD installed on the distribution line, and the SCADA server 1 locates the faulty line from multiple distribution lines according to the fault recording data. The faulty line can be quickly located throug...

Embodiment 2

[0046] In this embodiment, a distribution line fault location method is provided, Figure 4 is a flow chart of a distribution line fault location method according to an embodiment of the present invention, such as Figure 4 As shown, the process includes the following steps:

[0047] Step S41, collecting fault recording data through the distribution line fault location device FLD installed on the distribution line;

[0048] Step S42, locating faulty lines from a plurality of distribution lines according to the fault recording data.

[0049] Through the above steps, the fault recording data is collected by the distribution line fault location device FLD installed on the distribution line, and the faulty line is located from a plurality of distribution lines according to the fault recording data. The faulty line can be quickly located through the obtained fault recording data. Compared with the existing technology that only manually finds the fault point, it solves the problem...

Abstract

The invention provides a fault location method, device and system for distribution lines. The method includes: using distribution line fault location devices FLD mounted on the distribution lines to collect fault recording data; locating the faulted lines from the distribution lines according to the fault recording data. By the fault location method, the problems that fault points need to be located by power staff section by section and line by line, and a large amount of manpower, resources and time needs to be consumed in the prior art are solved, fast location of the faulted lines is achieved, and manpower and resource loss is reduced.

Description

technical field [0001] The invention relates to the field of electric power systems, in particular to a fault location method, device and system for distribution lines. Background technique [0002] Distribution lines have long transmission distances, many branch lines, most of which are overhead lines and cables, and the environment and weather conditions are harsh. Natural disasters such as external breakage, equipment failure, and lightning often cause high failure rates. [0003] Fault diagnosis technology is mainly divided into two categories: fault line selection and fault location. The so-called "fault line selection" means that after a fault occurs, the actual faulty line is selected among the many outgoing lines of the same bus. "Fault location" refers to pointing out the specific location or a certain section of the fault after the fault occurs, so as to facilitate the repair of the fault. [0004] Once a power outage occurs, it will firstly bring inconvenience t...
