Description

  The present invention relates to a restoration method selection support device for supporting restoration of distribution facilities such as supports and electric wires.

  Conventionally, emergency recovery manuals, etc. have been prepared and operated so that they can be immediately responded to, for example, when electric wires are cut or telephone poles are broken due to disasters or traffic accidents. ing. In addition, a disaster recovery integrated system has been established to deal with large-scale disasters.

  However, in normal times, it can be handled smoothly by a qualified person in charge, but for example, a person in charge (duty person) who has little experience in restoration of power distribution facilities may initially respond at night. Some offices have only one person in charge. The emergency recovery manual etc. are mounted on the vehicle so that they can be referred to locally, but in any case, it depends on the judgment of the person in charge. Therefore, if the person in charge has a low level of skill, it takes time to select a restoration method, and the burden on the person in charge is heavy. In addition, when the optimum construction method is not selected, restoration is delayed.

  Further, since the command office also makes a determination based on information from the local person in charge, if the correct information cannot be received, the restoration work is also delayed. That is, the processing time and processing accuracy vary depending on the skill level of the person in charge. However, accurate technical and technical expertise is indispensable for a reliable and smooth recovery response, and in addition to practical experience, predetermined education and training are required for acquisition.

  A technique has been proposed in which the damage status and the recovery status are sent from the damage area to a central management server using a mobile terminal, and the information is shared between the worker and the manager at the site (for example, , See Patent Document 1).

  Next, the operation of the distribution facility restoration support system will be described with reference to FIGS. First, the worker terminal 3 generates current position (imaging position) information of the worker terminal 3 based on the GPS information (step SA11 (FIG. 8)). Next, the worker terminal 3 captures a damage image and stores it in the storage unit 21 when the worker presses an image capture key. Here, if the damaged power distribution facility is, for example, a support, the imaging range is from the ground to the top. Next, the worker terminal 3 transmits the damage image information and the position information to the construction method selection support server 2 (step SA12).

  When the construction method selection support server 2 receives the damaged equipment image information and the position information from the worker terminal 3 (step SB11 (FIG. 9)), it is stored in the storage unit 11. Next, the construction method selection support server 2 sends, for example, the location information of the damaged equipment to the power distribution information management server 4, requests an original image corresponding to the damaged equipment (step SB12), and the power distribution information management server 4 sends the original image. Is acquired (step SB13), it is stored in the storage unit 11.

  Next, the construction method selection support server 2 points the facility position (for example, insulator position, electric wire position, etc.) to the damaged facility image and the original image corresponding to the damaged facility (step SB14). That is, the facility position is represented by a corresponding point (numerical value) instead of the actual measurement value. Next, the construction method selection support server 2 compares the pointed damaged equipment image with the original image corresponding to the damaged equipment, and generates displacement information for the original image of the damaged equipment image (step SB15). Next, the construction method selection support server 2 identifies a facility having a displacement abnormality based on the damaged facility image and the original image, and the displacement information of the facility position, and executes a damage situation grasping process.

  The construction method selection support server 2 is based on the damaged equipment image and the original image, and the displacement information of the equipment position, the aerial / underground, support (concrete pillar / wood pillar), brace, insulator, electric wire, transformer Then, the type of damage (type of damaged equipment) such as a switch is determined (step SC11 (FIG. 10)). The construction method selection support server 2 identifies a facility (and a damaged portion) having a displacement abnormality based on the damaged facility image and the original image and the displacement information of the facility position (determines the type). Here, the damage facility may be specified by, for example, pattern recognition.

  Next, the construction method selection support server 2 determines the state of damage, the scale of damage, and the like (step SC12). For example, when the damaged equipment is a support, the construction method selection support server 2 is inclined / collapsed, broken at the ground, broken at the middle, broken at the middle, broken at the top, washed away, and drained from the base sediment. Determine the damage content. It is also determined whether the damage support is singular or plural.

  Next, the construction method selection support server 2 determines whether or not the damaged equipment can be reused (step SC13). For example, if it is determined that the damaged facility has been washed away, it is determined that it cannot be reused. Next, the construction method selection support server 2 determines whether or not it is connected to an important load (for example, a hospital, a shelter, a lifeline facility, etc.), grasps a surrounding situation (whether a vehicle approach route is possible, etc.), etc. Is executed (step SC14). Here, the information on the related situation may be equipment related information supplied from the power distribution information management server 4 or equipment surrounding information input to the worker terminal 3 by the worker.

  Next, the construction method selection support server 2 selects a specific construction method based on the grasped damage situation (step SB17 (FIG. 9)). Next, the construction method selection support server 2 requests construction method information (standard work procedure information, etc.) corresponding to the selected construction method to the construction method information database server 5 (step SB18), and the construction method information is sent from the construction method information database server 5 to the construction method information. Is acquired (step SB19), it transmits to the worker terminal 3 (step SB20).

  The worker terminal 3 receives the construction method information from the construction method selection support server 2 (step SA13 (FIG. 8)) and stores it in the storage unit 21. Next, the worker terminal 3 displays the construction method type on the display unit 28 (step SA14), displays the necessary materials and tools (step SA15), and displays the detailed work procedure (step SA16).

  Next, the damage information grasping process executed by the construction method selection support server 2 will be described in detail. When the damaged facility is a support, for example, the construction method selection support server 2 determines the presence or absence of a high-voltage line or a low-voltage line (step SD11 (FIG. 11)). Next, the construction method selection support server 2 determines the number (single or plural) of damage supports (step SD12). Next, the construction method selection support server 2 determines the position of the damage support on the system (step SD13). That is, it is determined whether it is the start end, middle, or end of the main line, or the start end, middle, or end of the branch.

  Next, the construction method selection support server 2 determines whether or not the damage support is reusable (step SD14). Next, the construction method selection support server 2 determines whether or not it is connected to an important load (for example, a hospital, a shelter, a lifeline facility, etc.) (step SD15). Next, the construction method selection support server 2 executes a grasping process of the surrounding situation (whether the vehicle approach route is possible) (step SD16).

  Next, detailed construction method selection processing executed by the construction method selection support server 2 will be described in detail. If the damaged facility is a support, for example, the construction method selection support server 2 determines whether or not the damage support is reusable (step SE11 (FIG. 12)). If the damage support is reusable, the process proceeds to step SE12. If it cannot be reused, the process proceeds to step SE13. In step SE12, the construction method selection support server 2 determines whether or not wire laying and power transmission are possible. If the wire laying and power transmission are possible, the process proceeds to step SE14, and if not, the process proceeds to step SE20. That is, if there is a support, it is next considered to stretch the electric wire, and if there is no support, its construction is considered.

  In step SE14, the construction method selection support server 2 determines whether or not the wristband can be reused. If reuse is possible, the process proceeds to step SE15. If not, the process proceeds to step SE20. In step SE15, the construction method selection support server 2 determines whether or not an aerial work vehicle can be used. If it can be used, in step SE16, an intermediate line method (a method of adding a line in the middle of the span) is selected. Then, the process returns to the main routine, and if it cannot be used, the process proceeds to step SE20.

  In step SE13, the construction method selection support server 2 determines whether the ground clearance and the separation from other objects can be secured. If so, the process proceeds to step SE17, where the long span temporary construction method (a method for thinning the support) is performed. ) Is selected and the process returns to the main routine. If it cannot be secured, the process proceeds to step SE18. In step SE18, the construction method selection support server 2 determines whether or not there is a standing tree. If there is a standing tree, the process proceeds to step SE19, selects the standing tree utilization method, returns to the main routine, and if there is no standing tree. The process proceeds to step SE20.

  In step SE20, the construction method selection support server 2 selects the emergency construction method power transmission. That is, an emergency power transmission method is considered when a support cannot be used and an electric wire cannot be stretched. For example, when the support is broken at the intermediate portion, if it is determined that the degree of bending is small and the damage is slight, the intermediate reinforcing bracket construction method may be selected.

  The construction method selection support server 2 is based on the above-mentioned detailed work conditions in the emergency power transmission method. For example, when the damaged facility is a high-voltage line (aerial / underground), (1) power transmission by a high-voltage generator car, Select either (2) power transmission by laying a high-voltage bypass cable, or (3) power transmission by construction of a temporary route, or separation of damaged equipment. Here, the power transmission time is short and the number of personnel is minimized.

  (1) Power transmission using high-voltage generator cars enables power transmission to important loads (such as administrative facilities, hospitals, and evacuation centers under high-pressure contracts) and to areas that are gathered in islands. (2) Power transmission by laying a high-voltage bypass cable is possible not at the substation exit, etc., but at all if it is below the allowable current. (3) Power transmission by construction of a temporary route takes time and labor if the temporary route becomes longer, but full power transmission is possible.

  For example, as shown in FIG. 14, the damaged power distribution facility in the damaged section E1 is temporarily moved or removed, and is transmitted to the hospital C as an important load by the generator car D1. Alternatively, power is transmitted by the generator car D2 into a partial area ahead of the damaged section E2. Alternatively, the power from the power plant A3 is transmitted by avoiding the damaged section E3 and laying the high voltage bypass cable 35. Alternatively, power is transmitted through the temporary route by constructing the temporary pole 36 while avoiding the damaged section E4. Alternatively, the damaged section E5 is separated at the separation point 37, and power is transmitted to the healthy section. Here, it is assumed that the damaged section E6 is transmitted by the temporary restoration method.

  In addition, the construction method selection support server 2 is based on the detailed work conditions described above, for example, when the damaged facility is a low-voltage line (aerial / underground), (4) power transmission by a low-voltage generator vehicle, (5) movement Select only power transmission by transformer car, (6) power transmission by low-voltage mobile generator operation, or (7) power transmission by low-voltage bypass cable laying, construction of temporary route, or separation of damaged equipment. Here, the power transmission time is short and the number of personnel is minimized.

  (4) Power transmission by low-voltage generator car, and (5) Power transmission by mobile transformer car, power transmission to important loads (such as administrative facilities, hospitals, shelters, etc. under low-pressure contracts) and collective areas (transformers) Unit) can be transmitted. (6) The power transmission by the low-voltage mobile generator operation can be transmitted at a spot although the scale of the power transmission facility is small. (7) Power transmission by low-voltage bypass cable laying is possible if adjacent transformers or low-voltage lines can be accommodated.

This will be described more specifically. In FIG. 13, P ₁ , P ₄ , P ₆ , P ₉ , P _{3R 1} , P _{8R 2} , P _{8R 6} , Q ₁ , R ₁ are line switches, P ₂ , P ₃ , P ₅ , P ₇ , P _8. , P _{3R2 to} P _3R7 , P _3R4L1 , P _3L1 , P _8R1 , P _{8R3 to} P _8R5 , P _{8R4L1 to} P _8R4L3 , R ₂ , R ₃ , Q ₂ , Q ₃ represent a support (electric pole).

For example, the following damage is assumed in the damage section Sa. ○ It is _assumed that the line support P _3R5 (3 right 5) and the support P _3R6 (3 right 6) are washed away and the support P _3R4 (3 right 4) is broken _upward . It is assumed that there is a detour road and it is possible to pass. In this case, the construction method selection support server 2 grasps the damage status as follows, for example.

That is, there was damage to the support with the high voltage line. In addition, the support was damaged by several. The position on the system was in the middle of the branch side. There was also a high-pressure contract hospital at the end of the support P _3R7 (3 right 7). Next, the construction method selection support server 2 determines whether or not the support can be reused. The support P _3R5 (3 right 5) and the support P _3R6 (3 right 6) are determined to be non-reusable due to runoff. Further, the support P _3R4 (3 right 4) is broken only in the upper part, and the support P _3R5 (3 right 5) side has a long distance between the supports, and the wire ground height is insufficient. The P _3R4L1 (3 right 4 left 1) side can ensure separation.

For the support P _8R4L1 (8 right 4 left No. 1), select the arm _{metal lowering} method, and for the support P _8R4L2 (8 right 4 left 2), support P _8R4L3 (8 right 4 left 3) , Select the ground reinforcement metal fitting method. Since the support is reusable and the wires can be laid, a temporary restoration method is selected.

If the temporary restoration method is not applicable, it is decided to adopt the emergency power transmission method, and for the support P _8R4L1 (8 right 4 left 1), the corresponding detailed work conditions are satisfied, Select transmission by low-voltage generator car. Moreover, about the support _P8R4L3 (8 right 4 left 3), the power transmission by a low voltage | pressure moving generator is selected by satisfy | filling the said corresponding detailed work conditions.

  Next, the following damage is assumed in the damage section Sc. The line switch is defective. Here, although an alternative switch (inventory) is prepared and suspended at normal times, an adverse condition is assumed such that it takes time to secure workers in the event of a disaster. In this case, the construction method selection support server 2 grasps the damage status as follows, for example.

  That is, there was damage to the support with the high voltage line. Also, the support was one damage. In addition, the position on the system was the starting end on the branch side. Next, the construction method selection support server 2 determines whether or not the support can be reused. In addition, the construction method selection support server 2 determines whether or not there is a surplus length (margin) of the electric wire in the edge line portion, and if there is no surplus length, instructs the preparation of the additional line, and if the additional line cannot be prepared Determine whether the construction switch is ready. It is also determined whether or not an aerial work vehicle can be prepared. The construction method selection support server 2 instructs the preparation of the construction switch when the construction switch and the aerial work platform can be prepared. If either preparation is not possible, the edge line direct connection method is used. Select. If the temporary restoration method cannot be applied, it is determined that the emergency power transmission method will be adopted, and among these, the power transmission by the high-voltage generator car is selected because the corresponding detailed work conditions are satisfied.

  The above description has been made on the assumption that the construction method selection support server 2 and the worker terminal 3 are in a communicable state. However, the worker terminal can be automatically selected even when communication is not possible. 3, a part of the functions of the construction method selection support server 2 (and the distribution information management server 4 and the construction method information database server 5) described above may be added. In this case, the worker grasps the damage status, for example, inputs damage status information (including related status information) to the worker terminal 3 by selecting and inputting the presented (displayed) option information, The worker terminal 3 may execute detailed construction method selection processing and the like.

  Thus, according to the configuration of this embodiment, the construction method selection support server 2 identifies the equipment (and the damaged part) having the displacement abnormality based on the damaged equipment image and the original image, and the displacement information of the equipment position. Since the damage status, damage scale, etc. are judged, and a concrete construction method is selected based on the grasped damage situation, the construction method for restoration of distribution facilities and the implementation of the construction method can be smoothly implemented. Can contribute to do quickly and reliably.

  Further, for example, by performing work according to the display contents of the display unit 28 of the worker terminal 3, anybody can accurately and smoothly distribute power without requiring high-level specialized knowledge, regardless of proficiency or experience. Can be taken for recovery. Further, in daily work training (education training) for improving the skill level, work points and tips of work are added to the standard work procedure, thereby enabling safer work. Such construction method information can be shared not only with the power distribution department but also with other departments.

  The embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the gist of the present invention. Is included in the present invention. For example, in the above-described embodiment, in the construction method selection support server, damage facility image information acquisition processing, original image acquisition processing, facility position point conversion processing, facility position displacement information generation processing, damage information grasp processing, detailed construction method selection Processing, construction method information acquisition / transmission processing, etc. are performed by the control unit executing the corresponding control program, or part or all is performed using dedicated hardware, and the other part is a corresponding program May be processed. In addition, each CPU may execute, or for example, a single CPU may execute. Furthermore, each process may be performed by a separate information processing apparatus. The same applies to the worker terminal.
