A line fault location method, a system, an apparatus, and a storage medium according to embodiments of the present invention are described in detail below with reference to the accompanying drawings, and first, a line fault location method according to embodiments of the present invention will be described with reference to the accompanying drawings.
Referring to fig. 1, a line fault location method is provided in an embodiment of the present invention, and the line fault location method in the embodiment of the present invention may be applied to a terminal, a server, or software running in the terminal or the server. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, and the like. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud service, a cloud database, cloud computing, a cloud function, cloud storage, a network service, cloud communication, middleware service, a domain name service, a security service, a Content Delivery Network (CDN), a big data and artificial intelligence platform, and the like. The line fault positioning method in the embodiment of the invention mainly comprises the following steps:
s101, responding to the received first power failure event, preprocessing the first power failure event, and generating a second power failure event;
wherein the preprocessing comprises format conversion and equipment information conversion.
In an embodiment of the present invention, S101 may be further divided into the following steps S1011-S1012:
step S1011, converting the format of the first power failure event into a target format;
it can be understood that, in the embodiment of the present invention, the first power failure events sent by the respective systems are received, and formats of the first power failure events may be different. In the embodiment of the invention, the format of the first power failure event is converted into the target format, so that the first power failure event from different systems can be processed subsequently.
Optionally, the target format is a format that can be received and recognized by the embodiment of the present invention.
Step S1012, converting the device information in the first power outage event into target device information according to a preset device information mapping table, so as to obtain a second power outage event.
As can be seen from step S1011, the device information related to the first power outage event from different systems may be different. In the embodiment of the invention, the equipment information in the first power failure event is converted into the target equipment information through the preset equipment information mapping table, so that the first power failure event from different systems can be conveniently subjected to subsequent processing.
Optionally, the target device information is information such as a device ID that can be received and identified in the embodiment of the present invention.
And obtaining a second power failure event after completing the format conversion and the equipment information conversion of the first power failure event.
S102, comparing the time scale of the second power failure event with the preset power failure planning time to obtain a third power failure event;
the third power failure event is a second power failure event outside the power failure scheduled time.
S102 may further divide the following steps S1021-S1022:
step S1021, obtaining power failure planning time;
in an embodiment of the invention, the stored blackout schedule time is retrieved from a storage module.
And step S1022, comparing the time scale of the second power failure event with the power failure planning time, and eliminating the second power failure event within the power failure planning time range to obtain a third power failure event.
Specifically, the time scale of the second blackout event is compared with the blackout planning time, the second blackout event in the blackout planning time range is eliminated, and the remaining second blackout event is reserved as a third blackout event, namely, an abnormal blackout event (an unplanned blackout event).
And S103, positioning a suspicious switch and a fault area causing the third power failure event by combining the third power failure event and the action signal.
Wherein the action signals include a fault indicator action signal and a protection action signal.
Optionally, the fault indicator action signal comprises a normal turning action and a grounding turning action, and the protection action signal comprises a normal short-circuit fault and a zero-sequence fault.
Specifically, in step S103:
1. in combination with the third blackout event and the action signal, the method for locating the suspicious switch causing the third blackout event specifically comprises the following steps:
1) Starting from each power failure distribution transformer area, searching in the direction of a power supply to obtain a plurality of first switch sets, wherein the power failure distribution transformer area is a distribution transformer area with a third power failure event;
2) Solving the intersection of the first switch sets to obtain a second switch set;
3) And selecting the non-automatic switch closest to each power failure distribution transformer area from the second switch set as a suspicious switch, wherein the non-automatic switch is a switch without a real-time remote signaling and remote measuring function.
2. In combination with the third blackout event and the action signal, the fault area causing the third blackout event is located, which specifically includes:
1-1) confirming that a signal device with signals exists, and taking the signal device with signals farthest from a power supply as an upper boundary of a fault area, wherein the signal device with signals with actions exists;
1-2) taking an automatic switch as a lower boundary of a fault area, wherein the automatic switch is a switch with a real-time remote signaling and remote measuring function;
1-3) locating the fault region according to its upper and lower boundaries.
It can be understood that, when the signal device with signal is an automatic switch, the upper boundary and the lower boundary of the fault area of the embodiment of the present invention are both automatic switches, which is equivalent to the lower boundary of the fault area not existing, that is, the fault area is the area below the automatic switch.
2-1) confirming that no signal equipment exists, and taking a suspicious switch as an upper boundary of a fault area;
2-2) taking an automatic switch as a lower boundary of the fault area;
2-3) defining the fault region based on the upper and lower boundaries of the fault region.
It will be appreciated that the presence of a plurality of band signalling devices indicates the presence of a plurality of fault zones, each fault zone being bounded above by a corresponding band signalling device and below by a corresponding automation switch.

Case 3, receiving the first power failure event of the distribution transformer area 31, the distribution transformer area 32, the distribution transformer area 41, and the distribution transformer area 42, receiving the overcurrent protection action signals of the automatic switch 1 and the automatic switch 2, and not receiving the remote signaling of the opening on the power supply path:
