A line fault location method in an embodiment of the present invention mainly includes the following steps:

S101. In response to receiving the first power outage event, perform preprocessing on the first power outage event to generate a second power outage event;

Among them, the preprocessing includes format conversion and device information conversion.

In an embodiment of the present invention, S101 can be further divided into the following steps S1011-S1012:

Step S1011, converting the format of the first power outage event into the target format;

Wherein, it can be understood that the embodiment of the present invention receives the first power outage event sent by each system, and the format of the first power outage event may be different. In the embodiment of the present invention, the format of the first power outage event is converted into the target format, so as to facilitate subsequent processing of the first power outage event originating from different systems.

Optionally, the target format is a format that can be received and recognized by the embodiment of the present invention.

Step S1012: Convert the device information in the first power outage event into target device information according to the preset device information mapping table to obtain the second power outage event.

In conjunction with step S1011, it can be known that the equipment information involved in the first power outage event from different systems may be different. In the embodiment of the present invention, the device information in the first power outage event is converted into target device information through a preset device information mapping table, so as to facilitate subsequent processing of the first power outage event originating from different systems.

Optionally, the target device information is information such as a device ID that can be received and identified by the embodiment of the present invention.

After the format conversion and equipment information conversion of the first power failure event is completed, the second power failure event is obtained.

S102. Comparing the time scale of the second power outage event with the preset power outage plan time to obtain the third power outage event;

Wherein, the third power outage event is the second power outage event outside the planned power outage time.

S102 can be further divided into the following steps S1021-S1022:

Step S1021, obtaining the planned power outage time;

In the embodiment of the present invention, the stored power outage planned time is obtained from the storage module.

Step S1022 , comparing the time scale of the second outage event with the planned outage time, excluding the second outage event within the time range of the planned outage time, to obtain a third outage event.

Specifically, compare the time scale of the second outage event with the planned outage time, exclude the second outage event within the planned outage time range, and retain the remaining second outage event as the third outage event, which is an abnormal outage event (unplanned outage event).

S103. Combining the third power outage event and the action signal, locate the suspicious switch and fault area that caused the third power outage event.

Wherein, the action signal includes a fault indicator action signal and a protection action signal.

Optionally, the action signal of the fault indicator includes an ordinary flop action and a ground flop action, and the protection action signal includes an ordinary short-circuit fault and a zero-sequence fault.

Specifically, in step S103:

1. Combining the third blackout event and action signal, locate the suspicious switch that caused the third blackout event, including:

1) Starting from each power outage distribution substation area, search towards the direction of the power supply, and obtain several first switch sets, wherein the power outage distribution substation area is the distribution substation area where the third power outage event exists;

2) seeking the intersection of each first switch set to obtain a second switch set;

3) Select the non-automatic switch closest to each outage distribution substation area in the second switch set as the suspicious switch, wherein the non-automatic switch is a switch that does not have the function of real-time remote signaling and telemetry.

2. Combining the third blackout event and action signal, locate the fault area that caused the third blackout event, including:

1-1) Confirm that there is a signal-bearing device, and take the signal-bearing device farthest from the power supply as the upper boundary of the fault area, wherein the signal-bearing device is the device that has the action signal;

1-2) The automatic switch is used as the lower boundary of the fault area, and the automatic switch is a switch with real-time remote signaling and telemetry functions;

1-3) Locating the fault area according to the upper boundary and the lower boundary of the fault area.

It can be understood that when the signal-carrying device is an automatic switch, the upper boundary and the lower boundary of the fault area in the embodiment of the present invention are both automatic switches, which is equivalent to the fact that there is no lower boundary of the fault area, that is, the fault area is below the automatic switch. area.

2-1) Confirm that there is no signaling device, and use the suspicious switch as the upper boundary of the fault area;

2-2) Take the automatic switch as the lower boundary of the fault area;

2-3) The fault area is located according to the upper boundary and the lower boundary of the fault area.

It can be understood that when there are multiple signaling devices, it means that there are multiple fault areas, and each fault area takes the corresponding signaling device as the upper boundary and the corresponding automatic switch as the lower boundary.
