Embodiment

[0015] Embodiments, a 10kV distribution line fault location and recovery method, comprising the following steps:

[0016] Step S1, through the SCADA system, read the remote measurements and remote signal quantities of all the contact switches on the 10kV distribution line in real time; when the contact switch changes from closed position to partial position, first define the switch as a trip switch; and transfer to Step S2;

[0017] Step S2. After the trip switch trips, read the status of all tie switches on the 10kV distribution line through the SCADA system, and find a tie switch with voltage on the side away from the trip switch and no voltage on the side adjacent to the trip switch, then The tie switch is defined as the original hot standby switch; and go to step S3;

[0018] Step S3, close the original heat backup switch; if after closing the original heat backup switch, the rest of the contact switches on the distribution line between the original heat backup switch and...

Embodiment 2

[0022] Embodiment 2 is based on the basis of Embodiment 1, except for step S3, the rest is the same as Embodiment 2. After step S2, it includes step S3. Before closing the thermal standby switch, the states of all close state contact switches on the distribution line between the original thermal standby switch and the trip switch are switched from closed to open. ; Then close the original hot standby switch, if the original hot standby switch is closed and then changed from closed position to divided position, then the power distribution line between the original hot standby switch and the trip switch is defined as the faulty line section;

[0023] If the original heat standby switch is closed and operates normally, then switch the contact switch from the minute position to the close position in sequence in the direction from the original heat reserve switch to the trip switch; when the previous contact switch is closed and operates normally, close it A contact switch, if all ...

Abstract

The invention relates to a 10kV distribution line fault positioning and recovering method, which judges whether a fault is a transient fault through an SCADA (Supervisory Control and Data Acquisition) system and directly repairs the fault, and meanwhile, if the fault is not the transient fault, a fault point can be positioned to a fault line section. The problems that after tripping of an existing 10kV distribution line is found, line patrol personnel need to patrol the whole distribution line on site to find a fault point and carry out power distribution recovery, the workload is large, and the working efficiency is low are effectively solved.

Description

technical field [0001] The invention relates to the field of distribution line faults, in particular to a 10kV distribution line fault location and recovery method. Background technique [0002] In the field of power distribution, 10kV distribution lines often have the problem of distribution line tripping. On-site inspections are usually carried out by dedicated line inspectors. During the troubleshooting process, it is necessary to manually find the fault point in the entire power distribution line, and then repair the fault to restore the normal operation of the power distribution. In this process, because line inspectors are required to inspect the entire distribution line on site to find fault points and restore power distribution, there are problems of heavy workload and low work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a fault location and recovery method for 10kV power distribution lines, which can effectiv...
