Description

This invention relates to an accident point detection support device and an accident point detection support program, and more specifically, to a technology for identifying utility poles on which an accident point detection device can be attached when a power outage occurs due to a distribution line accident.

A voltage-applied fault point detection device is known as a device for detecting the fault point when a power outage occurs due to a distribution line accident (see Patent Document 1). This voltage-applied fault point detection device is connected to a utility pole in the power outage section and applies a high-voltage DC pulse, detecting the fault point from the state of the charging current and discharging current flowing through the high-voltage distribution line in the power outage section.

The voltage-applied fault location probe must be connected to a utility pole on which two transformers are installed. In addition, the voltage-applied fault location probe is relatively large in size and is used while mounted on a vehicle, so a parking space that the vehicle can enter is required around the utility pole to which the fault location probe is connected. Furthermore, the voltage-applied fault location probe must be grounded to the ground, so there must be ground that can be grounded around the utility pole to which the fault location probe is connected.

In conventional accident location investigation work, a list of transformers installed on utility poles and a map of the area around the site are checked, and utility poles on which an accident location investigation device can be attached are considered beforehand before heading to the site of the power distribution line accident. However, this investigation process takes time. In addition, at the actual site, the number of transformers installed and the installation conditions of utility poles are sometimes different from what was considered in advance, making it impossible to install the accident location investigation device, and new utility poles on which an accident location investigation device can be attached must be identified on site.

The objective of this invention is to provide an accident point detection support device and an accident point detection support program that can quickly and accurately identify in advance utility poles on which an accident point detection device can be attached.

In order to solve the above problem, the invention of claim 1 is an accident point exploration support device that identifies a utility pole to which an accident point exploration device can be attached when a power outage occurs due to a distribution line accident, and is characterized by comprising: a means for acquiring distribution equipment information related to the distribution equipment installed on the utility pole; a means for acquiring map information showing the installation position of the utility pole and information about the vicinity of the utility pole; a means for identifying, based on the distribution equipment information and the map information, a utility pole on which two or more transformers to which the accident point exploration device can be connected are installed and which is surrounded by a parking space in which a vehicle equipped with the accident point exploration device can enter and ground on which the accident point exploration device can be grounded, as a utility pole to which the accident point exploration device can be attached; and a means for presenting information about the utility pole to which the accident point exploration device can be attached.

The invention of claim 2 is characterized in that, in the fault location exploration support device described in claim 1, it is provided with a means for acquiring lightning strike information indicating the position of a lightning strike that occurred near the power outage section when the power outage occurred, and, if there are multiple utility poles on which the fault location exploration device can be attached, presents information about utility poles on which the fault location exploration device can be attached in order of proximity to the position of the lightning strike.

The invention of claim 3 is characterized in that, in the accident point location detection support device described in claim 1 , when there are multiple utility poles on which the accident point location detection device can be attached, information regarding the utility poles on which the accident point location detection device can be attached is presented in order of proximity to the starting position of the vehicle.

The invention of claim 4 is characterized in that in the accident point exploration support device described in any one of claims 1 to 3, the information presented regarding the utility pole on which the accident point exploration device can be attached includes a map image showing the installation position of the utility pole and the position of the lightning strike that occurred near the power outage section when the power outage occurred.

The invention of claim 5 is characterized in that, in the fault location exploration support device according to any one of claims 1 to 4, if it is not possible to identify a utility pole on which two or more transformers to which the fault location exploration device can be connected are installed, a utility pole is identified that can be climbed by an operator and used to attach the fault location exploration device to a high-voltage distribution line.

The invention of claim 6 is characterized in that, in the accident point exploration support device according to any one of claims 1 to 5, the process of identifying utility poles on which the accident point exploration device can be attached is performed using a trained model that has been machine-learned based on past performance data, so that when the distribution equipment information and the map information are input, utility poles on which the accident point exploration device can be attached are output.

The invention of claim 7 is an accident point exploration support program that identifies utility poles to which an accident point exploration device can be attached when a power outage occurs due to a distribution line accident, and is characterized in that it causes a computer to function as: means for acquiring distribution equipment information about the distribution equipment installed on the utility pole; means for acquiring map information showing the installation position of the utility pole and information about the vicinity of the utility pole; means for identifying, based on the distribution equipment information and the map information, utility poles on which two or more transformers to which the accident point exploration device can be connected are installed and which are surrounded by a parking space in which a vehicle equipped with the accident point exploration device can enter and ground on which the accident point exploration device can be grounded, as utility poles to which the accident point exploration device can be attached; and means for presenting information about utility poles to which the accident point exploration device can be attached.

According to the inventions of claims 1 and 7, based on the power distribution equipment information and map information, utility poles on which two or more transformers to which an accident point exploration device can be connected are installed, and which are surrounded by parking spaces in which a vehicle equipped with an accident point exploration device can enter, and ground on which the accident point exploration device can be grounded, can be identified as utility poles on which an accident point exploration device can be attached. This makes it possible to accurately identify utility poles on which an accident point exploration device should be attached and quickly restore a distribution line accident.

According to the invention of claim 2, information on utility poles on which the fault location probe can be attached is presented in order of proximity to the lightning strike location, making it possible to attach the fault location probe to utility poles that are close to the lightning strike location and are likely to be the cause of the power distribution line accident. This makes it possible to quickly restore the power distribution line accident.

According to the invention of claim 3, information about utility poles on which the fault location probe can be attached is presented in order of proximity to the starting position of the vehicle equipped with the fault location probe, making it possible to attach the fault location probe to utility poles where the vehicle can arrive early. This makes it possible to quickly restore power distribution line accidents.

According to the invention of claim 4, the information presented about the utility pole on which the fault point detection device can be attached includes a map image showing the installation location of the utility pole and the location of the lightning strike that occurred near the power outage section when the power outage occurred. Therefore, even if there are multiple lightning strike locations, multiple workers can check the presented information and split up the work to detect the fault point, making it possible to quickly restore the distribution line fault.

According to the invention of claim 5, if it is not possible to identify a utility pole on which two or more transformers to which the fault point detection device can be connected are installed, a utility pole on which an operator can climb and attach the fault point detection device to the high-voltage distribution line is identified. This eliminates the need to search for a utility pole that can be connected to the high-voltage distribution line at the site of the distribution line accident, and enables rapid recovery from the distribution line accident.

According to the invention of claim 6, the process of identifying utility poles on which the fault point detection device can be attached is performed using a trained model that has been machine-learned based on past performance data so that when distribution equipment information and map information are input, utility poles on which the fault point detection device can be attached are output. This allows for accurate identification of utility poles on which the fault point detection device can be attached, enabling rapid recovery from distribution line accidents.

The present invention will be described below based on the illustrated embodiment.

Figure 1 is a functional block diagram showing a schematic configuration of a power distribution system 1 including an accident point exploration support device according to an embodiment of the present invention. The power distribution system 1 of this embodiment is a system for managing a high-voltage power distribution system, and is composed of a power distribution automation system 2, a power distribution map information system 3, a map information providing system 4, a lightning strike position assessment system 5, and an accident point exploration support device 6. The power distribution automation system 2, the power distribution map information system 3, the lightning strike position assessment system 5, and the accident point exploration support device 6 are installed, for example, in a power company. The map information providing system 4 is installed in a company that provides map information. The power distribution automation system 2, the power distribution map information system 3, the map information providing system 4, the lightning strike position assessment system 5, and the accident point exploration support device 6 are connected via various wireless/wired communication line networks NW, including a LAN (Local Area Network) and a WAN (Wide Area Network), so that they can transmit and receive signals and information to each other.

The power distribution automation system 2 is a system that aims to reduce the labor and improve the efficiency of power distribution system operation and to improve supply reliability. By remotely monitoring and controlling the sectioning switches of the power distribution system, the power distribution automation system 2 performs planned switching of the power distribution system and automatic switching of the power distribution system so that power is transmitted to sections other than the accident section when a sudden power outage occurs due to a power distribution line accident or the like. When a power outage occurs due to a power distribution line accident or the like, the power distribution automation system 2 transmits high-voltage power distribution line power outage information to the accident point investigation support device 6. The high-voltage power distribution line power outage information includes information about the power outage section.

The power distribution map information system 3 is a system that allows the type, number, and installation location of power distribution equipment to be confirmed by overlaying and displaying information about a high-voltage power distribution system on a map image. Although not shown in detail, the power distribution map information system 3 is composed of a general-purpose computer equipped with a central processing unit such as a CPU (Central Processing Unit), a memory such as a RAM (Random Access Memory), a storage unit such as a hard disk, an input unit such as a keyboard and a mouse, a display unit such as a display, and a communication unit for communicating through a communication line network NW.

The storage unit of the power distribution map information system 3 stores a map information database (hereinafter, the database is also referred to as DB) 31, an equipment ledger database 32, an equipment image database 33, and the like. The map information DB 31 is a database in which map information such as buildings, roads, railway tracks, and rivers is recorded and accumulated. The equipment ledger DB 32 is a database in which power distribution equipment information relating to various types of power distribution equipment installed in a high-voltage power distribution system is stored. The equipment image DB 33 is a database in which image data of equipment images (also referred to as pole images) of power distribution equipment captured by a digital camera, a mobile terminal such as a smartphone, and the like is stored. The equipment images are included in the power distribution equipment information of the present invention.

Figure 2 shows an example of a map screen 34 displayed on the display unit by the power distribution map information system 3. A map image 35 selected by the user through operation of the input unit is displayed on the map screen 34. In addition to the line names and utility pole numbers of the high-voltage power distribution system, equipment symbols 35a to 35l indicating power distribution equipment such as utility poles, electric wires, and transformers are displayed superimposed on the map image 35. When an equipment symbol is selected on this map image 35 through the input unit, an equipment image of the power distribution equipment corresponding to the selected equipment symbol is displayed on the map screen 34. Figure 3 shows, for example, a state in which the utility pole with equipment symbol 35c (utility pole number: 009M06) has been selected, and an equipment image 36 of the utility pole with equipment symbol 35c is displayed on the right side of the map screen 34.

Figure 4 shows an example of the data layout of the equipment ledger DB 32 of the power distribution map information system 3. Note that although each piece of data is represented as a character string in Figures 4 and 5, in reality, appropriate coding processing is performed so that the data can be used in computer processing, and appropriate conversion processing is performed, such as converting location information into latitude and longitude.

In the equipment ledger DB32 of the power distribution map information system 3, distribution equipment information is stored, including line names, utility pole numbers, and utility pole position information for high-voltage power distribution systems, as well as information regarding high-voltage power distribution lines, transformers, and switches. Information regarding high-voltage power distribution lines stores the "number" of high-voltage power distribution lines. Information regarding transformers includes the "capacity," "type," and "application" of the transformer. Information regarding switches includes the "capacity" and "type" of the switch.

Figure 5 shows an example of the data layout of the equipment image DB 33 of the power distribution map information system 3. The equipment image DB 33 of the power distribution map information system 3 stores the "photographing location information" of the equipment image in association with the "file name". Image data of the equipment image is captured after the construction of the power distribution equipment is completed, and is imported into the equipment image DB 33 of the power distribution map information system 3 by the construction worker. The "photographing location information" is obtained from a GNSS (Global Navigation Satellite System) receiver built into the digital camera or mobile terminal used to capture the equipment image, and is imported into the equipment image DB 33 together with the image data.

The map information providing system 4 is a system that provides two-dimensional map image information, satellite photo images (or aerial photo images), panoramic images in which images of the surroundings of each point are captured in advance, and the like. Examples of this map information providing system 4 include Google Maps (registered trademark), Google Earth (registered trademark), and Street View (registered trademark), which are provided by Google (registered trademark). In this embodiment, aerial photo images from which information about the surroundings of utility poles can be obtained are used as the map information provided by the map information providing system 4.

The lightning location assessment system 5 is a system that detects the location of a lightning strike, the time of the strike, the magnitude of the lightning current, the polarity of the lightning current, etc. The lightning location assessment system 5 is composed of multiple lightning observation sensors and a central processing unit, and the lightning observation sensors capture LF band electromagnetic waves generated during a lightning strike and transmit them to the central processing unit. The central processing unit calculates and analyzes the data sent from the lightning observation sensors, locating the location of the lightning strike in real time, and calculating the time of the lightning strike, the magnitude of the lightning current, the polarity of the lightning current, etc. The lightning location assessment system 5 transmits lightning information, including the location of the lightning strike, the time of the strike, etc., to the accident point exploration support device 6.

The fault point exploration support device 6 is a device for identifying a utility pole on which the fault point exploration device can be attached when a power outage occurs due to a distribution line accident. The fault point exploration device used in this embodiment is, for example, a voltage-applied fault point exploration device that is connected to a utility pole in a power outage section and applies a high-voltage DC pulse to explore the fault point from the state of the charging current and discharging current flowing through the high-voltage distribution line in the power outage section. This voltage-applied fault point exploration device is relatively large in size and is used while mounted on a vehicle, so a parking space that the vehicle can enter is required around the utility pole to which the fault point exploration device is connected. Furthermore, since the voltage-applied fault point exploration device needs to be grounded, a ground that can be grounded is required around the utility pole to which the fault point exploration device is connected.

The accident point detection support device 6 mainly comprises an input unit 61, a display unit 62, a storage unit 63, a memory 64, a main task 65, a communication unit 66, and a central processing unit 67 that controls these. The accident point detection support device 6 is configured, for example, by installing a control program for the entire device and an application (accident point detection support program 631) for performing various processes for identifying and correcting discrepancies in the power distribution equipment information on a personal computer or the like.

The input unit 61 is an interface that has the function of inputting information to the accident point investigation support device 6 upon receiving commands from the user, and is composed of, for example, a keyboard and a mouse.

The display unit 62 has functions such as displaying information input via the input unit 61 and displaying the processing results of the accident point exploration support device 6, and is configured, for example, by a liquid crystal display.

The memory unit 63 is a memory area/storage device with the function of storing various information, programs, data, etc., and is configured by, for example, a hard disk. The memory unit 63 stores a control program for the entire accident point exploration support device 6 and an accident point exploration support program 631. The memory unit 63 also stores a trained model 632 for identifying utility poles on which the accident point exploration device can be attached based on the distribution equipment information and equipment images acquired from the distribution map information system 3, the aerial photograph images acquired from the map information providing system 4, and the lightning information acquired from the lightning strike position assessment system 5, and a database 633 of teacher data used for machine learning of the trained model 632.

The memory 64 is a storage area/storage device that functions as a working area for temporarily storing information and data generated when the central processing unit 67 executes various processes to identify utility poles on which the fault point detection device can be attached, and is composed of, for example, a RAM.

The main task 65 is a group of tasks that execute various processes to identify utility poles on which an accident point exploration device can be attached, and is realized by executing the accident point exploration support program 631 stored in the memory unit 63.

The communication unit 66 is a communication interface that has the function of transmitting/receiving/inputting/outputting signals and information transmitted via the communication line network NW.

The central processing unit 67 has the function of coordinating and controlling each part that constitutes the accident point investigation support device 6, and is configured to include a central processing unit such as a CPU, and realizes each function according to the control program and the accident point investigation support program 631 stored in the memory unit 63.

For example, when the fault point exploration support device 6 receives high-voltage distribution line power outage information transmitted from the power distribution automation system 2, it executes various processes to identify a utility pole on which the fault point exploration device can be attached from among multiple utility poles in the power outage section. This process is performed by a main task 65 that is configured by executing the fault point exploration support program 631 stored in the memory unit 63. The main task 65 includes a power distribution facility information acquisition task 651, a map information acquisition task 652, a lightning information acquisition task 653, a utility pole identification task 654, an information presentation task 655, and a learning task 656.

The power distribution equipment information acquisition task 651 corresponds to a means for acquiring power distribution equipment information related to the power distribution equipment installed on the utility pole. The map information acquisition task 652 corresponds to a means for acquiring map information indicating the installation position of the utility pole and information related to the vicinity of the utility pole. The lightning strike information acquisition task 653 corresponds to a means for acquiring lightning strike information indicating the position of a lightning strike that occurred near the power outage section when a power outage occurred. The utility pole identification task 654 corresponds to a means for identifying, based on the power distribution equipment information and the map information, a utility pole on which two or more transformers to which the fault point exploration device can be connected are installed, and which is surrounded by a parking space in which a vehicle equipped with the fault point exploration device can enter and ground on which the fault point exploration device can be grounded, as a utility pole on which the fault point exploration device can be attached. The information presentation task 655 corresponds to a means for presenting information related to a utility pole on which the fault point exploration device can be attached.

The learning task 656 corresponds to a means for machine learning the learned model 632 using the teacher data DB 633, which is past performance data, so that when distribution equipment information and map information are input, utility poles on which a fault point exploration device can be attached are output.

When the fault point investigation support program 631 is executed, the power distribution equipment information acquisition task 651 acquires power distribution equipment information within the power outage section from the equipment ledger DB 32 of the power distribution map information system 3 via the communication line network NW, and acquires equipment images within the power outage section from the equipment image DB 33. The acquired power distribution equipment information and equipment images are temporarily stored in the memory 64.

When the fault point investigation support program 631 is executed, the map information acquisition task 652 acquires an aerial photograph image including the power outage section from the map information provision system 4 via the communication line network NW. The acquired aerial photograph image is temporarily stored in the memory 64. In addition, the map information acquisition task 652 displays, based on the power distribution equipment information, a symbol indicating the position of the utility pole, a line indicating the power distribution route, the line name of the power distribution system, and the utility pole number, superimposed on the acquired aerial photograph image.

Figure 6 shows an example of an aerial photograph image 6521 acquired from the map information providing system 4 by the map information acquisition task 652. Also, Figure 7 shows an example of a state in which a symbol Sy1 indicating the position of a utility pole, lines L1, L2, and L3 indicating a power distribution route, and the line name and utility pole number of the power distribution system are superimposed on the aerial photograph image 6521 by the map information acquisition task 652. Note that the line indicating the power distribution route has a different thickness for healthy sections where power is being transmitted and sections where a power outage has occurred. In the example shown in FIG. 7, line L1 extending horizontally from Makuwa Branch 005 to Makuwa Branch 009B6 and line L21 extending vertically from Makuwa Branch 009B1 to Makuwa Branch 014 indicate healthy sections, while line L3 extending vertically from Makuwa Branch 009B1 to Makuwa Branch 009M07 indicates the power outage section, and line L3 is thinner than lines L1 and L2.

When the fault point exploration support program 631 is executed, the lightning information acquisition task 653 acquires lightning information indicating the location of a lightning strike that occurred near the power outage section (for example, within 500 m of a utility pole in the power outage section) at the time of the power outage from the lightning strike location assessment system 5 via the communication line network NW. The acquired lightning strike information is temporarily stored in the memory 64. Note that if no lightning strike occurs at the time of the power outage, no lightning strike information is acquired.

The map information acquisition task 652 displays a symbol indicating the location of the lightning strike and the time of the lightning strike superimposed on the acquired aerial photograph image based on the lightning strike information. Figure 8 shows an example of a state in which the map information acquisition task 652 displays the symbol Sy2 indicating the location of the lightning strike and the time of the lightning strike superimposed on the aerial photograph image 6521.

The utility pole identification task 654 identifies utility poles on which a fault point detection device can be attached based on the power distribution equipment information and equipment images obtained from the power distribution map information system 3 and the aerial photograph images obtained from the map information providing system 4 showing the positions of utility poles, power distribution routes, lightning strike positions, etc.

In the utility pole identification task 654, when distribution equipment information, equipment images, and aerial photograph images are input, a trained model 632 that has been machine-learned is used to output information about utility poles on which a fault point exploration device can be attached (e.g., utility pole number, utility pole location information, etc.).

Specifically, the utility pole identification task 654 identifies, from among the utility poles in the outage section, a utility pole on which two transformers to which the fault point exploration device can be connected are installed, based on the power distribution equipment information and the analysis results of the equipment image. In addition, based on an aerial photograph image showing the position of the utility pole, the power distribution route, the position of the lightning strike, and the like, the utility pole identification task 654 identifies, from among the utility poles on which two transformers are installed, a utility pole on which there is a parking space in the vicinity where a vehicle equipped with the fault point exploration device can enter and ground on which the fault point exploration device can be grounded. By using the aerial photograph image as map information, it is possible to obtain information on the vicinity of the utility pole, and therefore it is possible to determine whether or not there is a parking space in which a vehicle can enter and ground on which the fault point exploration device can be grounded.

In addition, when the lightning strike location is marked on the aerial map image and there are multiple utility poles on which an accident point exploration device can be attached, the utility pole identification task 654 ranks the multiple utility poles on which an accident point exploration device can be attached in order of proximity to the lightning strike location. As will be described in more detail later, the information presentation task 655 presents information about utility poles on which an accident point exploration device can be attached based on this ranking.

In addition, if there are multiple utility poles on which the accident point exploration device can be attached, the utility pole identification task 654 ranks the multiple utility poles on which the accident point exploration device can be attached in order of proximity to the starting position of the vehicle on which the accident point exploration device is mounted. As will be described in more detail later, the information presentation task 655 presents information about utility poles on which the accident point exploration device can be attached based on this ranking.

The trained model 632 is created by the learning task 656. The learning task 656 uses past performance data recorded and accumulated in the teacher data DB 633 stored in the memory unit 63 to create the trained model 632 by a known machine learning algorithm such as a neural network. The teacher data DB 633 is a database that records and accumulates, as input information, previously acquired power distribution equipment information, equipment images, and aerial photograph images, information about utility poles identified based on this information (utility pole number and utility pole position information), and performance data (see FIG. 9) that corresponds to whether the identified utility pole has been used to install a fault point exploration device.

The learning task 656 uses machine learning and deep learning using a neural network to create a neural network including an intermediate layer based on the performance data recorded in the teacher data DB 633, in which, for example, the power distribution equipment information, equipment images, and aerial photograph images are used as an input layer, and information on utility poles on which the fault point exploration device can be attached is used as an output layer. The learning task 656 then uses the performance data in the teacher data DB 633 as learning data to learn about various parameters in the intermediate layer. The learning task 656 learns various parameters in the intermediate layer so that utility poles on which the fault point exploration device can be attached can be identified quickly and accurately from the power distribution equipment information, equipment images, and aerial photograph images.

If the exact number of installed transformers cannot be identified from the distribution facility information or facility image, the number of high-voltage distribution lines may be identified from the distribution facility information or facility image, and utility poles to which three high-voltage distribution lines are connected may be identified as utility poles to which the fault point detection device can be attached. If a utility pole with two transformers installed or a utility pole to which three high-voltage distribution lines are connected cannot be identified from utility poles in the power outage section, the fault point detection device is connected to the high-voltage distribution line to detect the fault point, so that a utility pole that is easy for the fault point detection device to connect to the high-voltage distribution line may be identified. Note that a utility pole that is easy for a worker to connect to a high-voltage distribution line by the fault point detection device is preferably one that is free of obstacles such as trees or buildings around the utility pole and is easy for a worker to climb when climbing the utility pole and connecting the fault point detection device to the high-voltage distribution line.

The information presentation task 655 displays the processing results of the utility pole identification task 654 on the display unit 62, thereby presenting information about utility poles on which an accident point exploration device can be attached to the user. Specifically, as shown in FIG. 10, the information presentation task 655 displays on the display unit 62 utility pole presentation information 6551A about utility poles on which an accident point exploration device can be attached, and an information presentation screen 6553A including an aerial photograph image 6552A showing the utility pole position, power distribution route, lightning strike position, etc., in the map information acquisition task 652.

In the utility pole presentation information 6551A, if there are multiple utility poles on which the fault point exploration device can be attached, information on the multiple utility poles is presented. Also, as described above, if the utility pole identification task 654 ranks multiple utility poles on which the fault point exploration device can be attached based on the lightning strike position, information on the utility poles on which the fault point exploration device can be attached is presented according to the ranking. The utility pole presentation information 6551A shown in FIG. 10 presents, for example, information on utility poles ranked based on the aerial photograph image 6521 shown in FIG. 8. In the aerial photograph image 6521 shown in FIG. 8, for example, if the poles 009M3, 009M4, and 009M5 are poles to which an accident point exploration device can be attached, the pole identification task 654 ranks the poles in the order of 009M4, 009M3, and 009M5 according to their distance from the lightning strike position Sy2, and the information presentation task 655 presents information about the poles from top to bottom according to this ranking. This makes it possible to attach an accident point exploration device to a pole close to the lightning strike position that is likely to be the cause of the distribution line accident, thereby enabling rapid recovery from the distribution line accident.

As described above, in the utility pole identification task 654, if multiple utility poles on which the accident point exploration device can be attached are ranked based on the starting position of the vehicle on which the accident point exploration device is mounted, information about the utility poles on which the accident point exploration device can be attached is presented according to the ranking. The utility pole presentation information 6551B on the information presentation screen 6553B shown in FIG. 11 presents, for example, information about utility poles ranked based on the aerial photograph image 6521 shown in FIG. 7. In the aerial photograph image 6521 shown in FIG. 7, for example, if the poles Makuwa 009M3, Makuwa 009M4, and Makuwa 009M5 are poles to which an accident point exploration device can be attached, and a vehicle equipped with an accident point exploration device departs from Makuwa 009M7 toward Makuwa 009M1, the utility pole identification task 654 ranks the poles in the order of Makuwa 009M5, Makuwa 009M4, and Makuwa 009M3 according to the departure position of the vehicle, and the information presentation task 655 presents information about the utility poles from top to bottom according to this ranking. This makes it possible to attach an accident point exploration device to the utility pole where the vehicle arrives first, thereby enabling rapid recovery from the distribution line accident.

When ranking multiple utility poles based on both the lightning strike location and the starting position of a vehicle equipped with an accident point exploration device, it is preferable to prioritize the ranking of the lightning strike location, since the accident point exploration device can be attached to a utility pole close to the lightning strike location that is most likely to be the cause of a distribution line accident. In addition, ranking may be performed using the average of the ranking based on the lightning strike location and the ranking based on the starting position of the vehicle, or the user may be allowed to select which ranking to prioritize.

Next, the operation of the above embodiment will be described based on the flowchart shown in FIG. 12. For example, when the fault point detection support device 6 receives high-voltage distribution line power outage information transmitted from the power distribution automation system 2, it executes various processes to identify a utility pole on which a fault point detection device can be attached from among multiple utility poles in the power outage section (step S1).

The main task 65, which is configured by executing the fault point investigation support program 631, acquires distribution equipment information within the power outage section from the equipment ledger DB 32 of the distribution map information system 3 via the communication line network NW using the distribution equipment information acquisition task 651, and acquires equipment images within the power outage section from the equipment image DB 33 (step S2). The distribution equipment information and equipment images are temporarily stored in the memory 64.

The map information acquisition task 652 acquires an aerial photograph image including the power outage section from the map information providing system 4 via the communication line network NW (step S3). The acquired aerial photograph image is temporarily stored in the memory 64. The map information acquisition task 652 also displays, based on the power distribution equipment information, symbols indicating the positions of utility poles, lines indicating the power distribution routes, the line names of the power distribution system, and utility pole numbers superimposed on the acquired aerial photograph image.

The lightning information acquisition task 653 acquires lightning information indicating the location of a lightning strike that occurred near the power outage section at the time of the power outage from the lightning strike location assessment system 5 via the communication line network NW (step S4). The acquired lightning strike information is temporarily stored in the memory 64. Note that if no lightning strike occurs at the time of the power outage, the lightning strike information is not acquired.

The utility pole identification task 654 identifies utility poles on which the fault point exploration device can be attached based on the power distribution equipment information and equipment images obtained from the power distribution map information system 3 and the aerial photograph images obtained from the map information providing system 4 and showing the positions of utility poles, power distribution routes, lightning strike positions, etc. (step S5). When the power distribution equipment information, equipment images, and aerial photograph images are input, the utility pole identification task 654 uses a trained model 632 that has been machine-learned to output information on utility poles on which the fault point exploration device can be attached.

The information presentation task 655 displays the processing results of the utility pole identification task 654 on the display unit 62, thereby presenting the user with information about utility poles on which an accident point exploration device can be attached (step S6). The user checks the processing results displayed on the display unit 62, goes to the site of the power distribution line accident, and, referring to the processing results, attaches an accident point exploration device to the utility pole and explores the accident point.

As described above, the accident point exploration support device 6 and the accident point exploration support program 631 can identify, based on the power distribution equipment information and map information, utility poles on which two or more transformers to which the accident point exploration device can be connected are installed, and which are surrounded by a parking space in which a vehicle equipped with the accident point exploration device can enter, and ground on which the accident point exploration device can be grounded, as utility poles on which the accident point exploration device can be attached. This makes it possible to accurately identify the utility pole on which the accident point exploration device should be attached and quickly restore power distribution line accidents.

In addition, the fault point exploration support device 6 and the fault point exploration support program 631 present information about utility poles on which the fault point exploration device can be attached in order of proximity to the lightning strike location, making it possible to attach the fault point exploration device to utility poles close to the lightning strike location, which are likely to be the cause of the power distribution line accident. This makes it possible to quickly restore power distribution line accidents.

Furthermore, according to the fault point exploration support device 6 and the fault point exploration support program 631, information on utility poles on which the fault point exploration device can be attached is presented in order of proximity to the starting position of the vehicle on which the fault point exploration device is mounted, making it possible to attach the fault point exploration device to utility poles where the vehicle can arrive early. This makes it possible to quickly restore power distribution line accidents.

In addition, according to the fault point exploration support device 6 and the fault point exploration support program 631, the information presented about the utility pole on which the fault point exploration device can be attached includes a map image showing the installation location of the utility pole and the location of the lightning strike that occurred near the power outage section when the power outage occurred. Therefore, even if there are multiple lightning strike locations, multiple workers can check the presented information and split up the work to explore the fault point, enabling rapid recovery from the power distribution line accident.

Furthermore, according to the fault point exploration support device 6 and the fault point exploration support program 631, if it is not possible to identify a utility pole on which two or more transformers to which the fault point exploration device can be connected are installed, a utility pole on which an operator can climb and attach the fault point exploration device to the high-voltage distribution line is identified. This eliminates the need to search for a utility pole that can be connected to the high-voltage distribution line at the site of the distribution line accident, and enables rapid recovery from the distribution line accident.

In addition, according to the accident point exploration support device 6 and the accident point exploration support program 631, when distribution equipment information and map information are input, the process of identifying utility poles on which the accident point exploration device can be attached is performed using a trained model that has been machine-learned based on past performance data so that utility poles on which the accident point exploration device can be attached are output. This allows for accurate identification of utility poles on which the accident point exploration device can be attached, enabling rapid recovery from distribution line accidents.
