Description

Technical Field

[0001] This invention relates to the field of layout optimization technology, and in particular to a low-carbon and energy-saving integrated layout optimization method and system for power distribution cabinets. Background Technology

[0002] With the continuous development of industrial production, building power supply and infrastructure construction, distribution cabinets, as important equipment for power distribution, control and protection, are widely used in low-voltage power distribution sites. Distribution cabinets typically house feeder switch units, auxiliary power supply units, protective grounding busbars, and door accessory access structures. These functional units are interconnected through power supply paths, auxiliary power supply paths, and protective connection paths, forming a complex electrical relationship. To meet the installation requirements of different application scenarios, some distribution cabinets require adjustments to the positions of internal functional units to improve cabinet space utilization, optimize power supply paths, and adjust equipment structure. In actual operation, the inner side of the cabinet door typically uses grounding braided tape for protective connection between the cabinet door accessories and the cabinet body. After long-term bending caused by the opening and closing of the cabinet door, local strand breakage may occur near the crimping bend of the grounding braided tape. The free end of the broken strand may re-lap, creating a re-lapped area that is difficult to observe directly. When the power supply path inside the distribution cabinet passes near this re-lapped area, it can easily cause spatial interference between the power supply path and the re-lapped area. Therefore, when adjusting the internal layout of the distribution cabinet, it is necessary to analyze the positional relationship between the re-lapped area of ​​the broken strand of the grounding braided tape and the power supply path, and optimize the installation position of the relocatable units based on the analysis results.

[0003] In existing technologies, the optimization of the internal layout of distribution cabinets is usually based on the equipment installation space, electrical connection distance, and manual experience to adjust the position, or only on the path optimization based on the conductor length and installation space. It is difficult to consider the impact of the grounding braided strip breakage and re-lapping area formed during the cabinet door movement on the power supply and distribution path layout. When there is a grounding braided strip breakage and re-lapping situation, the existing layout method cannot accurately identify the surrounding relationship and crossing relationship between the power supply and distribution path and the re-lapping area. As a result, the adjusted power supply and distribution path may still pass through the breakage and re-lapping area. At the same time, the existing methods usually do not comprehensively consider the changes in conductor loss caused by the change of power supply and distribution path, making it difficult to simultaneously meet the requirements of path safety and low loss in the process of distribution cabinet layout optimization. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing layout methods in the prior art, which cannot accurately identify the surrounding and crossing relationships between power supply and distribution paths and back-mounted areas, and to propose a low-carbon and energy-saving integrated layout optimization method and system for power distribution cabinets.

The position sequence layout module optimizes the layout of movable units in the target power distribution cabinet based on the globally optimal installation position sequence, and obtains the layout result.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention addresses the problem of inaccurately locating the overlapping area caused by localized breakage of the grounding braided tape due to long-term movement of the distribution cabinet door. By collecting images of the grounding braided tape inside the cabinet door, the invention identifies the location of the crimped bend, the location of the free end of the broken strand re-threading, and the overlapping location of the free end of the broken strand, generating data on the overlapping location of the broken strand. Combined with the cabinet door rotation process, the overlapping shadow range is determined, allowing the indirectly observable affected area to be converted into analyzable spatial location data, thus improving the accuracy of abnormal area identification during internal layout adjustments of the distribution cabinet.

[0016] 2. Unlike methods that adjust solely based on installation space or conductor length, this invention utilizes the positional relationship between the back-overlapping tape and the unfolded power supply and distribution path data to analyze the number of wrapping paths and the number of crossing paths, further identifying the affected power supply and distribution units. Furthermore, it optimizes and evaluates the installation sequence of multiple movable units using a particle swarm optimization algorithm, enabling the layout scheme to take into account both the need to avoid broken strand back-overlapping areas and changes in power supply and distribution path losses, thus avoiding path intersections and unreasonable layouts caused by manual experience adjustments.

[0017] 3. By obtaining the globally optimal installation sequence and generating corresponding layout instructions, this invention can guide the rearrangement of feeder switch functional units, auxiliary power supply units, and related connection positions. At the same time, it optimizes the power supply and distribution path based on the adjusted installation relationship, so that the final distribution cabinet layout reduces the occurrence of path crossing back and forth shadows and reduces the additional losses caused by changes in conductor length, thereby improving the operational reliability and energy-saving layout effect of the distribution cabinet.

[0018] The accompanying drawings, which are included to provide a further understanding of the invention and form part of this application, illustrate exemplary embodiments of the invention and, together with their description, serve to explain the invention and do not constitute an undue limitation thereof. In the drawings: Figure 1 This is a flowchart illustrating a low-carbon, energy-saving integrated layout optimization method for power distribution cabinets, as provided in an embodiment of the present invention. Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] This embodiment provides a method for optimizing the integrated layout of power distribution cabinets to reduce carbon emissions and increase energy consumption. (See also...) Figure 1 Specifically, including: S1. Obtain the broken strand re-attachment position from the grounding braided strip image inside the target distribution cabinet door; rotate and unfold the broken strand re-attachment position to obtain the re-attachment image strip. In an embodiment of the present invention, obtaining the break-even point includes: Obtain an image of the grounding braided strip inside the target distribution cabinet door; With the target distribution cabinet under power outage maintenance and the cabinet door fixed in a position where stable image acquisition is possible, remove dust and obstructions from the surface of the grounding braided strip inside the cabinet door. Ensure the door-side crimping end, the starting braid section, broken strand areas, and adjacent braided strands of the grounding braided strip are fully exposed. Place the calibration piece with dimensional scales within the plane of the grounding braided strip. Orient the optical axis of the image acquisition device towards the plane of the grounding braided strip. Adjust the position of the image acquisition device so that the door-side crimping end, the main body of the grounding braided strip, and the calibration piece are all within the imaging range. (The image acquisition device is then positioned using a method where the grounding braid is distributed within the grounding braided strip.) The grounding braided strip is illuminated by light sources on both sides. A front image of the grounding braided strip and a side image acquired at an angle along the thickness direction of the grounding braided strip are acquired respectively. Distortion correction is performed on the acquired images. The correspondence between image pixels and actual length is established according to the scale in the calibration piece. The front image and the side image are spatially registered according to the outline of the crimp end, the outer edge of the braided strip, and the intersection of the braided texture. The registered image is cropped to include the area of ​​the crimp end on the cabinet door side and the exposed part of the grounding braided strip, thus obtaining the grounding braided strip image of the target distribution cabinet inside the cabinet door.

[0021] The location of the crimping bend root is obtained by identifying the edge of the crimping end and the bend of the starting braided section in the image of the grounding braid. The crimped end edge refers to the physical boundary formed at the junction of the metal crimped end of the grounding braided tape and the exposed braided tape body. This physical boundary defines the starting position of the grounding braided tape transitioning from a rigid fixed area to a flexible braided area. Crimped end edge recognition refers to determining the position of the metal crimped end boundary in the image based on the differences in contour shape, surface texture, and extension direction between the metal crimped end and the braided tape body. The starting braided segment refers to the first exposed braided tape body extending from the crimped end edge towards the main body of the grounding braided tape. This segment is simultaneously subject to the fixed constraint of the crimped end and the bending effect caused by the opening and closing of the cabinet door. Starting braided segment bend recognition refers to determining the bending area where the starting braided segment changes from the crimped end extension direction to the main body extension direction based on the changes in the contour direction and the braided strand arrangement direction of the starting braided segment. The crimped bend root position refers to the position adjacent to the crimped end edge and the bending area of ​​the starting braided segment. This position is the physical part where the curvature begins to concentrate when the grounding braided tape transitions from a crimped fixed state to a free bending state. Grayscale variations, edge continuity, and surface texture direction in the grounding braided tape image are extracted. The metal plate-like region with a continuous closed contour and uniform surface texture is identified as the cabinet door side crimping end region. The contour of the cabinet door side crimping end region facing the grounding braided tape body is identified as the crimping end edge. The continuous region extending from the crimping end edge to the grounding braided tape body with an interlaced braid texture is identified as the starting braided segment. Multiple continuous contour points are extracted along the outer contours on both sides of the starting braided segment. The center extension line of the starting braided segment is determined according to the extension direction of adjacent contour points. The directional change at each position is calculated along the center extension line. The continuous bending region where the center extension line changes from the crimping end extension direction to the grounding braided tape body extension direction is identified as the bending region of the starting braided segment. The connection position between the crimping end edge and the bending region of the starting braided segment is identified as the crimping bend root position. The coordinates of the crimping bend root position in the grounding braided tape image after spatial registration and the actual position coordinates calculated based on the calibration parts are recorded as the crimping bend root position.

[0022] Obtain the location of the free end of the broken strand re-threading from the grounding braid image; Starting from the crimped bend, continuous texture lines of each braided strand are extracted along the direction from the initial braided section to the main body of the grounding braided tape. Based on the interlacing relationship of the texture lines at the braiding intersection, the original extension path of each braided strand is established. The area where the original extension path is interrupted and the end of the interruption still retains the outline of the metal wire is found. The end of the metal wire is identified as the free end of the broken strand. The outline of the free end of the broken strand is traced along the actual extension direction of the free end of the broken strand to determine the entrance position where the free end of the broken strand deviates from the original extension path and enters the gap between adjacent braided strands. Combined with the lateral image, it is determined whether the free end of the broken strand enters the braided tape from one side surface of the grounding braided tape or passes through the other side surface at the entrance position. The position that satisfies the above spatial penetration relationship is identified as the return position of the free end of the broken strand. The coordinates of the return position of the free end of the broken strand in the grounding braided tape image after spatial registration and the actual position coordinates calculated according to the calibration are recorded as the return position of the free end of the broken strand.

[0023] Obtain the overlap position of the free end of the broken strand from the grounding braided tape image; The broken strand free end refers to the end formed after the metal wire breaks and can bend, slide, or interweave relative to the adjacent braided strand bundle; the braided gap refers to the physical gap formed between the intersecting metal wire bundles in the grounding braided tape, and the shape of this gap changes with the bending and compression state of the braided tape; the broken strand free end re-penetration position refers to the physical position corresponding to when the broken strand free end deviates from the original extension direction of the metal wire, enters the adjacent braided gap, and passes from one side of the braided tape to the other side; re-penetration refers to the physical movement state of the broken strand free end re-penetrating into the braided tape or exiting to the other surface of the braided tape under the bending or compression action of the braided tape caused by the closing of the cabinet door; Starting from the point where the free end of the broken strand retraces back through the grounding braided tape image, the continuous contour of the free end in the front and side images is traced towards its end. The edge points and center line of the free end are extracted. Based on the extension direction of the center line, the actual extension path of the free end after leaving the retracing point is determined. The contours of each braided strand adjacent to the actual extension path are extracted. The spatial contact relationship between the end of the free end and each braided strand is compared. The position where the end of the free end makes contour contact, pressing contact, or overlapping contact with the non-original extension strand is determined as the overlap position of the free end. The coordinates of the overlap position of the free end in the grounding braided tape plane are determined using the front image with completed spatial registration. The height position of the overlap position of the free end relative to the surface of the grounding braided tape is determined using the side image. Based on the image calibration results, the plane coordinates and height position are converted into actual spatial coordinates to obtain the overlap position of the free end.

[0024] The location of the crimped bend, the location of the free end of the broken strand returning to its original position, and the location of the free end of the broken strand overlapping are combined into the location of the broken strand overlapping.

[0025] Braided strands refer to a strip-shaped conductive portion formed by multiple metal wires arranged in a similar direction. Different braided strands are connected by cross contact to form a grounding braided tape. The overlapping position of the broken strand free end refers to the physical position when the broken strand free end, after completing the back-through, contacts, presses against, or overlaps with another braided strand. This position is different from the continuous extension position of the metal wire to which the broken strand free end belongs before the breakage. Overlap refers to the state in which the broken strand free end forms physical contact with another braided strand and constitutes an additional conductive contact relationship. The broken strand back-overlap position refers to the local spatial area of ​​the grounding braided tape defined by the pressing bend position, the broken strand free end back-through position, and the broken strand free end overlap position. It is used to characterize the physical positional relationship between the broken strand starting point, the broken strand free end insertion point, and the broken strand free end re-contact point.

[0026] It should be noted that the broken strands refer to the single or multiple metal wires that make up the grounding braided strip. Due to the bending, stretching, squeezing or friction caused by the repeated opening and closing of the cabinet door, the broken metal wire loses its physical state of complete connection with the original continuous extension. The broken end of the metal wire can still be held by the adjacent braided strands and remain inside or on the surface of the grounding braided strip, and can be bent, slipped, interlaced or overlapped relative to the adjacent braided strands.

[0027] Using the data of the crimped bend location, the free end of the broken strand back through location, and the free end of the broken strand overlapping location as input, the coordinate reference of the inner mounting surface of the target distribution cabinet door is uniformly adopted. The crimped bend location, the free end of the broken strand back through location, and the free end of the broken strand overlapping location are respectively converted to this coordinate reference. The position association is established in the order from the crimped bend location to the free end of the broken strand back through location and then to the free end of the broken strand overlapping location. The actual spatial coordinates of the three locations, the connection order between the three locations, and the local spatial range defined by the three locations are recorded. The position association results and the local spatial range are combined to form the broken strand back overlapping location.

[0028] In an embodiment of the present invention, obtaining the back-attachment radiograph includes: Acquire the door movement data of the target power distribution cabinet; Cabinet door motion data refers to the spatial motion information generated by the target distribution cabinet door during opening, closing or rotation, including the position of the door rotation center, the direction of rotation and the spatial attitude change of the door relative to the cabinet body; The rotation center of the cabinet door is determined at the connection position between the cabinet door and the cabinet body. The reference direction of the cabinet door movement is established based on the position of the cabinet door hinge axis. Spatial position data of the cabinet door in the open and closed states are collected. The angle change information of the cabinet door plane relative to the cabinet body mounting surface during the rotation of the cabinet door is recorded. Based on the relationship between the rotation center of the cabinet door, the rotation direction of the cabinet door, and the spatial posture change of the cabinet door, cabinet door motion data is generated so that the cabinet door movement process can correspond to the internal space of the target distribution cabinet.

[0029] Based on the cabinet door motion data, the broken strand re-attachment position is rotated and unfolded to obtain the closed trajectory of the broken strand re-attachment part. The rotation and unfolding process refers to simulating the spatial position change of the broken strand overlap position during the change of the cabinet door from an open state to a closed state based on the cabinet door motion data, converting the broken strand overlap position fixed on the cabinet door into a continuous spatial trajectory that changes with the cabinet door movement; the closed trajectory of the broken strand overlap part refers to the spatial movement path generated by the pressing bend root position, the broken strand free end back-through position, and the broken strand free end overlap position of the broken strand overlap position as the cabinet door closes. This trajectory is used to represent the range of movement of the broken strand overlap part in the cabinet space during the cabinet door closing process; The positions of the crimped bend, the free end of the broken strand, and the overlapping position of the free end of the broken strand in the overlapping position of the broken strand are converted into the reference coordinates of the cabinet door movement. The spatial relationship between each position point and the rotation center is determined according to the rotation center of the cabinet door. Based on the relationship between the rotation direction and the posture change of the cabinet door in the cabinet door movement data, spatial rotation calculations are performed on each position point to obtain the position change data of the overlapping position of the broken strand under different cabinet door postures. The position change data of each position are connected according to the closing movement sequence of the cabinet door to obtain the closed trajectory of the overlapping part of the broken strand, and the continuous spatial range traversed by the overlapping part of the broken strand during the movement of the cabinet door is determined.

[0030] Determine the suitable installation area for the target distribution cabinet; The installable area refers to the effective installation space area inside the target distribution cabinet for arranging power supply and distribution units. This area is defined by the internal structure of the cabinet, the location of the mounting surface, and the space occupied by existing components. The internal structure of the target distribution cabinet is divided into spatial sections. The actual spatial position data of the mounting plate, guide rail, partition and installed components inside the cabinet are obtained. Based on the actual spatial position data of each component, the unoccupied space area inside the cabinet that can accommodate the power supply and distribution unit is determined. The space area inside the cabinet is converted to the same spatial coordinate reference as the closed trajectory of the broken strand reconnection part. The boundary position of the available installation area is marked to generate the installable area of ​​the target distribution cabinet.

[0031] The overlapping area between the closed trajectory of the broken strand reattachment section and the installable area is extracted to obtain the swept area data; Overlapping area extraction refers to comparing the spatial position of the closed trajectory of the broken strand reattachment with the installable area to determine the range of areas where the two coexist in the cabinet space; swept area data refers to the spatial area information traversed by the closed trajectory of the broken strand reattachment during its movement within the cabinet, including the boundary position, coverage area, and corresponding installation surface position within the cabinet. The closed trajectory data of the broken strand reconnection section and the installable area data of the target distribution cabinet are converted to the same spatial coordinate reference. Based on the positional relationship between the spatial coordinates of each point in the closed trajectory of the broken strand reconnection section and the boundary coordinates of the installable area, the spatial intersection relationship between the spatial range traversed by the closed trajectory of the broken strand reconnection section and the installable area is determined. The trajectory points located inside the installable area are filtered, and the continuously distributed trajectory points are connected to form the spatial area jointly covered by the closed trajectory of the broken strand reconnection section and the installable area. The boundary contour, coverage area and corresponding installation surface position of this spatial area are extracted to obtain the swept area data.

[0032] The scanned area data is marked to obtain the re-examination video.

[0033] Area marking refers to the location recording and identification of the spatial range corresponding to the scanned area data, so that the spatial range can be used as the basis for subsequent path analysis and layout adjustment; the back overlap shadow refers to the continuous spatial influence area formed by the closed trajectory of the broken strand back overlap part in the installable area, which is used to indicate the cabinet area that the broken strand back overlap part may pass through or occupy during the cabinet door movement.

[0034] The boundary contours in the scanned area data are converted to the coordinates of the mounting surface inside the target distribution cabinet. Based on the spatial position corresponding to the scanned area data, the projection range on the mounting surface inside the cabinet is determined. Continuous areas within the projection range are numbered and marked, and the positional correspondence between the area boundary position, the area coverage direction, and the closed trajectory between the area and the broken strand reconnection part is recorded. The scanned area with complete boundaries is stored as the reconnection image tape, so that the reconnection image tape can represent the mounting area inside the cabinet affected by the broken strand reconnection part during the cabinet door movement.

[0035] For example, taking a certain type of drawer-type distribution cabinet as the target distribution cabinet, when acquiring the cabinet door motion data, the coordinates of the cabinet door hinge axis were detected as 120 mm in the X-axis direction, 35 mm in the Y-axis direction, and 260 mm in the Z-axis direction. During the rotation of the cabinet door from the open state to the closed state, the rotation angle of the cabinet door changed from 90 degrees to 0 degrees. The coordinates of the crimped bend position at the broken strand overlap position were recorded as 260 mm in the X-axis direction, 80 mm in the Y-axis direction, and 180 mm in the Z-axis direction; the coordinates of the broken strand free end re-penetration position were recorded as 275 mm in the X-axis direction, 86 mm in the Y-axis direction, and 182 mm in the Z-axis direction; and the coordinates of the broken strand free end overlap position were recorded as 290 mm in the X-axis direction, 90 mm in the Y-axis direction, and 185 mm in the Z-axis direction. Based on the rotation angle change relationship in the cabinet door motion data, spatial rotation and unfolding calculations were performed on the above three position coordinates to obtain... During the cabinet door closing process, the crimping bend position moves from coordinates 260 mm, 80 mm, 180 mm to coordinates 220 mm, 80 mm, 180 mm; the free end of the broken strand retracing position moves from coordinates 275 mm, 86 mm, 182 mm to coordinates 235 mm, 86 mm, 182 mm; and the free end of the broken strand overlapping position moves from coordinates 290 mm, 90 mm, 185 mm to coordinates 250 mm, 90 mm, 185 mm. The continuous spatial trajectories formed by these three positions within the rotation range of 90 degrees to 0 degrees are connected to obtain the closed trajectory of the broken strand overlapping part. The spatial range of the intersection of this closed trajectory and the internal installation area of ​​the distribution cabinet is determined. The swept area data covering 220 mm to 250 mm in the X-axis direction and 80 mm to 90 mm in the Y-axis direction are extracted, and the swept area is marked to generate the overlapping image.

[0036] This step acquires image data of the grounding braided strip inside the target distribution cabinet door, and identifies the crimped bend, the back-through position of the free end of the broken strand, and the overlap position of the free end of the broken strand in the broken strand overlap location. This can convert the local broken strand overlap state, which is difficult to detect manually in the traditional way, into locatable position data. Combined with the cabinet door movement process, the broken strand overlap position is rotated and unfolded to form an overlap shadow, thereby accurately describing the spatial change range of the broken strand overlap area during the opening and closing of the cabinet door. This provides basic data for subsequent analysis of the positional relationship between the power supply and distribution path and the broken strand overlap area, avoiding the problem of inaccurate adjustment of the distribution cabinet layout caused by the inability to identify hidden broken strand areas in the existing technology.

Expand the installation surface inside the cabinet for the power supply and distribution path of the back-overlay tape and the target distribution cabinet to obtain the number of tape paths; mark the power supply and distribution path to obtain the number of tape paths. In embodiments of the present invention, obtaining the number of surrounding paths includes: Obtain the power supply and distribution path of the target distribution cabinet; wherein, the power supply and distribution path includes the incoming and outgoing connection path of the feeder switch functional unit, the power supply path from the auxiliary power supply unit to the door panel accessories, and the protection connection path from the power supply and distribution unit to the protective grounding busbar; The power supply and distribution path refers to the physical conductive connection lines used to transmit electrical energy or establish electrical connections between various electrical units inside the target distribution cabinet. This includes the input and output connection paths of the feeder switch functional unit, the power supply path from the auxiliary power supply unit to the door panel accessories, and the protective connection path from the power supply and distribution unit to the protective grounding busbar. The input and output connection path of the feeder switch functional unit refers to the wire arrangement path that forms the power transmission between the feeder switch functional unit and the external power input terminal and the load output terminal. The power supply path from the auxiliary power supply unit to the door panel accessories refers to the corresponding wire connection path when the auxiliary power supply unit provides power to the indicating device, control device, or other auxiliary electrical components installed on the cabinet door. The protective connection path from the power supply and distribution unit to the protective grounding busbar refers to the conductive path that forms the protective grounding connection between the metal shell or protective grounding point of the power supply and distribution unit and the protective grounding busbar. The cabinet mounting surface unfolding process refers to the process of converting the position of the power supply and distribution path and the overlapping shadow strip position in the three-dimensional space inside the target distribution cabinet to the position expression on a unified mounting plane, so that data from different spatial positions can be analyzed accordingly. Establish a spatial coordinate reference for the internal space of the target distribution cabinet. Transform the area boundary position, coverage area, and spatial direction information in the overlay image data to this coordinate reference. At the same time, transform the feeder switch function unit incoming and outgoing line connection path, the power supply path from the auxiliary power supply unit to the door panel accessory, and the protection connection path from the power supply and distribution unit to the protective grounding busbar in the power supply and distribution path data to the same spatial coordinate reference. Determine the unfolding reference plane according to the position and direction of the mounting plate inside the target distribution cabinet. Project the overlay image area and the power supply and distribution path in three-dimensional space along the direction perpendicular to the mounting surface. Map the projected area outline and path centerline to the plane coordinate of the mounting surface. Preserve the overlay image area boundary, the extension direction of the power supply and distribution path, and the relative positional relationship between the path and the overlay image to obtain the path unfolding data.

[0038] The installation surfaces inside the cabinet are expanded to obtain the expanded path data for the back-mounted video strip and power supply and distribution path. The path unfolding data refers to the data set formed after the installation surface inside the cabinet has been unfolded, including the unfolded position of the power supply and distribution path on the installation surface, the path extension direction, and the positional relationship with the back-overlay tape; Based on the actual dimensions of the mounting surface inside the cabinet, establish the unfolded two-dimensional positional relationship. Unfold the feeder switch functional unit's incoming and outgoing line connection paths, the auxiliary power supply unit's power supply path to the door panel accessories, and the power distribution unit's protection connection path to the protective grounding busbar according to the original connection direction. Record the starting position, ending position, path length, and extension direction of each power distribution path in the unfolded plane. At the same time, mark the boundary position and coverage area of ​​the back-overlay image strip in the unfolded plane. Record the intersection position, adjacent position, and distribution direction between the power distribution path and the back-overlay image strip, forming path unfolding data that includes the unfolded positions of the power distribution path and the back-overlay image strip.

[0039] Based on the path expansion data, determine the power supply path and protection connection path corresponding to the power supply and distribution unit; The power supply path refers to the forward power supply connection line in the power supply and distribution unit used to transmit the working current; the protection connection path refers to the safety connection line in the power supply and distribution unit used to transmit the fault current and connect to the protective grounding point. The feeder switch function unit incoming and outgoing line connection paths, auxiliary power supply unit to door panel accessories, and protection connection paths from power distribution unit to protective grounding busbar in the path expansion data are classified according to their respective power distribution units. The power distribution unit corresponding to each power distribution path is determined according to the starting and ending connection positions of each power distribution path. The connection path used to transmit working current is determined as the power supply path, and the connection path used to conduct fault current is determined as the protection connection path. The correspondence between power distribution unit and power supply path and protection connection path is established to obtain the power supply path and protection connection path corresponding to the power distribution unit.

[0040] The relationship between the power supply path, protection connection path, and back-over image zone is identified separately to obtain the surrounding path marking data; Side-to-side relationship identification refers to determining the spatial relationship between the power supply path and the protection connection path on different sides of the back-covering strip based on their relative positions in the unfolded plane; the surrounding strip path marking data refers to the power supply and distribution path location information determined after side-to-side relationship identification, which is used to represent the path data where the power supply path and the protection connection path are separated by the back-covering strip. The power transmission path, protection connection path, and back-overlay shadow strip in the path expansion data are transformed to the same expansion plane coordinates. Based on the positional relationship between the center line of the power transmission path, the center line of the protection connection path, and the boundary of the back-overlay shadow strip, the distribution direction of the power transmission path and the protection connection path relative to the back-overlay shadow strip is determined. When the power transmission path and the protection connection path corresponding to the same power supply and distribution unit are located on different sides of the back-overlay shadow strip and there is no intersection with the back-overlay shadow strip, the path position corresponding to the power supply and distribution unit is marked, and the power supply and distribution unit number, the power transmission path position, the protection connection path position, and the positional relationship of the back-overlay shadow strip are recorded to obtain the ring path marking data.

[0041] The number of paths in the encirclement path marker data is counted to obtain the number of encirclement paths.

[0042] The number of enclosed paths refers to the number of power supply and distribution paths in the enclosed path marking data that satisfy the separation arrangement relationship.

[0043] The power supply and distribution unit numbers in the belt path marking data are extracted. The number of power supply and distribution paths that satisfy the belt relationship is determined according to the marking records corresponding to different power supply and distribution units. Each path record corresponding to a power supply and distribution unit that satisfies the belt relationship is taken as a belt path. The number of belt paths is obtained by counting all belt path records.

[0044] It should be noted that the number of encircling paths is used to represent the number of power supply and distribution paths that have a back-overlapping shadow strip separation relationship. Therefore, the number of encircling paths can be obtained by statistically analyzing the encircling path marking data. This is because each record in the encircling path marking data corresponds to a power supply and distribution unit that satisfies the encircling relationship. The power supply path and protection connection path in this power supply and distribution unit are located on different sides of the back-overlapping shadow strip, indicating that the power supply and distribution path is within the encircling influence range of the broken strand back-overlapping part during the cabinet door movement. When the number of records of all power supply and distribution units in the encircling path marking data is counted, the statistical result is the number of power supply and distribution paths affected by the back-overlapping shadow strip separation, thus obtaining the number of encircling paths.

[0045] In embodiments of the present invention, obtaining the number of webbing paths includes: Based on the path expansion data, determine the positional relationship between the power supply and distribution path and the back-connection shadow strip; The positional relationship refers to the spatial correspondence between the power supply and distribution path and the back-overlay strip after the power supply and distribution path is unfolded on the cabinet mounting surface, including the positional state of the power supply and distribution path when it is inside, outside, intersecting or adjacent to the back-overlay strip. The location of the power supply and distribution path, the direction of path extension, and the boundary of the back-covering shadow strip in the path expansion data are transformed to the same installation surface coordinates. The position of the path centerline is extracted along the direction of the power supply and distribution path extension, and the spatial distance relationship between the path centerline and the boundary of the back-covering shadow strip is determined. It is determined whether the power supply and distribution path enters the coverage area of ​​the back-covering shadow strip. The position where the centerline of the power supply and distribution path intersects with the boundary of the back-covering shadow strip is determined as the crossing position, and the position where the centerline of the power supply and distribution path is completely outside the back-covering shadow strip area is determined as the non-crossing position. The spatial correspondence between the power supply and distribution path and the back-covering shadow strip is recorded to obtain the positional relationship between the power supply and distribution path and the back-covering shadow strip.

[0046] Based on the location relationship, the power supply and distribution path is marked to obtain the tape path marking data; The data for marking power supply and distribution paths refers to the data recorded based on the positional relationship between the power supply and distribution path and the back-coverage video strip, indicating that there is a spatial intersection between the power supply and distribution path and the back-coverage video strip. The path refers to the power supply and distribution connection line that, after the power supply and distribution path is unfolded in the cabinet mounting surface, intersects with the back-coverage video strip area and passes through the coverage of the back-coverage video strip. The path marking refers to the process of recording and numbering the power supply and distribution path that meets the set spatial positional relationship, including recording the power supply and distribution unit corresponding to the path, the starting position of the path, the ending position of the path, and the positional relationship between the path and the back-coverage video strip. The power supply and distribution path number, power supply and distribution unit number, and spatial correspondence between the power supply and distribution path and the back-over-the-viewing-line (HOL) in the location relationship data are associated. Based on the location relationship of the power supply and distribution path entering the HOL area, the power supply and distribution paths that intersect with the HOL are filtered out. The start position, end position, intersection position, and power supply and distribution unit information of the corresponding power supply and distribution path are recorded. A cross-line marker is added to the location area corresponding to the path expansion data to form cross-line path marking data, so that the cross-line path marking data can represent the power supply and distribution path that has a cross-line relationship.

[0047] The number of paths in the tape path marking data is counted to obtain the number of tape paths.

[0048] The number of thread-crossing paths refers to the total number of power supply and distribution paths marked as passing through the back-overlapping area in the thread-crossing path marking data. This number is used to indicate the scale of the power supply and distribution path affected by the movement range of the broken strand back-overlapping part.

[0049] The power supply and distribution path numbers in the tape-crossing path marking data are extracted. Based on the marking record corresponding to each power supply and distribution path number, the power supply and distribution paths with tape-crossing relationships are determined. Each power supply and distribution path with tape-crossing relationships is treated as a statistical object. The number of statistical objects in all tape-crossing path marking data is accumulated to obtain the number of tape-crossing paths.

[0050] It needs to be explained that the number of wire-crossing paths is used to represent the number of power supply and distribution paths that cross the area affected by the back-overlapping shadow strip. Therefore, the number of wire-crossing paths can be obtained by statistically analyzing the wire-crossing path marking data. This is because each record in the wire-crossing path marking data corresponds to a power supply and distribution path that has a spatial intersection with the back-overlapping shadow strip. The unfolded center line or the path coverage area of ​​this power supply and distribution path has entered the back-overlapping shadow strip range, indicating that the path passes through the spatial area that may be affected by the broken wire back-overlapping part during the cabinet door movement. When the number of all path records in the wire-crossing path marking data is statistically analyzed, the statistical result is the number of power supply and distribution paths that have a back-overlapping shadow strip crossing relationship, thus obtaining the number of wire-crossing paths.

[0051] S3. Based on the number of surrounding paths and the number of through paths, the first and second transferable units are deduplicated to obtain transferable units; the particles in the particle swarm algorithm are determined according to the transferable units, and the candidate path expansion data is obtained according to the installation order of the particles. In an embodiment of the present invention, a transferable unit is obtained, comprising: An anomaly relationship table is generated based on the number of belt paths and the number of belt crossing paths; The abnormal relationship table refers to the data record of the influence relationship between the power supply and distribution unit and the back-overlay shadow belt, which is established based on the number of belt-enclosing paths and the number of belt-crossing paths. This data record is used to represent the power supply and distribution unit with back-overlay influence relationship and its corresponding path status. The internal structure of the target distribution cabinet is spatially located to determine the actual spatial positions of the cabinet mounting plate, mounting rails, supports, and existing electrical components. Based on the unoccupied areas inside the cabinet and the installation requirements of the electrical units, the available space for arranging power distribution units is determined. Areas suitable for installing feeder switch functional units are marked, and the coordinates of the mounting surface, spatial boundaries, and connection directions of these areas are recorded to form the installable locations for feeder switch functional units. Areas suitable for installing auxiliary power supply units are also marked, and their corresponding installation positions are determined based on the connection directions between the auxiliary power supply unit and the feeder switch functional units and door panel accessories, forming the installable locations for auxiliary power supply units. Based on the fixed area of ​​the protective grounding branch connection structure within the cabinet, the spatial position of the protective grounding branch connection point is determined, and the connection point position and installation direction are recorded to form the installable locations for the protective grounding branch connection point. Finally, based on the location where the corresponding lines of the cabinet door accessories enter the cabinet, the cabinet access positions for the door panel accessories are determined, and the coordinates of the access points and the direction of line extension are recorded to form the installable locations for the door panel accessory access points within the cabinet.

[0052] Obtain the possible installation locations of the target distribution cabinet; among which, the possible installation locations include the possible installation locations of the feeder switch functional unit, the possible installation locations of the auxiliary power supply unit, the possible installation locations of the protective grounding branch connection position, and the possible installation locations of the access positions inside the door panel accessory cabinet; The installable location refers to the specific spatial location inside the target distribution cabinet used to fix or arrange electrical units. This location is determined by the cabinet mounting structure, mounting surface space, and corresponding connection conditions. The installable location of the feeder switch functional unit refers to the installation area inside the target distribution cabinet used to install the feeder switch functional unit. This location determines the arrangement of the feeder switch functional unit inside the cabinet. The installable location of the auxiliary power supply unit refers to the installation area inside the target distribution cabinet used to install the auxiliary power supply unit. This location determines the spatial connection relationship between the auxiliary power supply unit and other electrical components. The installable location of the protective grounding branch connection position refers to the installation location inside the target distribution cabinet used to set up the protective grounding branch connection component. This location forms the connection path between the power distribution unit and the protective grounding busbar. The installable location of the door accessory cabinet access position refers to the internal access position corresponding to the cabinet door accessory of the target distribution cabinet. This location is used to arrange the power supply line or control line connected to the cabinet door accessory. The installation locations of the feeder switch functional unit, auxiliary power supply unit, protective grounding branch connection position, and access position inside the door panel accessory cabinet are converted to a unified spatial coordinate system inside the target distribution cabinet. Installation location data records are established based on the spatial coordinates, installation area boundaries, and connection directions of each installation location, so that each installation location corresponds to the actual installation area inside the target distribution cabinet. All types of installation location data are classified and stored according to the power supply and distribution unit category to form the installation locations of the target distribution cabinet.

[0053] Based on the anomaly relationship table, the power supply and distribution units corresponding to the belt path marking data are extracted to obtain the first migrateable unit; The first relocatable unit refers to the power supply and distribution unit whose installation position needs to be adjusted according to the path marking data of the enclosure. The power supply path and protection connection path corresponding to the power supply and distribution unit are located on both sides of the enclosure. Using the encirclement path marker data in the abnormal relationship table as the retrieval basis, the power supply and distribution unit number, power supply and distribution unit type, and corresponding installation location information associated with the encirclement path marker data are obtained. The power supply and distribution unit number is matched with the actual installed components inside the target distribution cabinet to determine the power supply and distribution unit with the encirclement relationship. The name information, current installation location data, and associated power supply path data of the corresponding power supply and distribution unit are combined to form the first migrateable unit data, where the first migrateable unit data represents the power supply and distribution unit whose power supply path and protection connection path are located on both sides of the back-overlapping shadow strip.

[0054] Based on the anomaly relationship table, the power supply and distribution units corresponding to the tape path marking data are extracted to obtain the second migrateable unit; The second relocatable unit refers to the power supply and distribution unit whose installation position needs to be adjusted according to the tape path marking data. The power supply and distribution path corresponding to this power supply and distribution unit has an intersection with the tape. Using the tape-crossing path marker data in the abnormal relationship table as the retrieval basis, the power supply and distribution unit number, power supply and distribution unit type, and corresponding power supply and distribution path data associated with the tape-crossing path marker data are obtained. Based on the power supply and distribution unit number, the power supply and distribution unit that has an intersection relationship with the tape-crossing area is determined. The name information, current installation location data, and tape-crossing path location data of the corresponding power supply and distribution unit are combined to form the second movable unit data, where the second movable unit data represents the power supply and distribution unit whose power supply and distribution path passes through the tape-crossing area.

[0055] The first and second transferable units are deduplicated to obtain the transferable units.

[0056] Deduplication refers to merging duplicate power supply and distribution units in the first and second portable units, retaining the unique record of each different power supply and distribution unit, and obtaining portable units.

[0057] The power supply and distribution unit numbers in the first transferable unit data are matched with the power supply and distribution unit numbers in the second transferable unit data. For the same power supply and distribution unit that exists in both the first and second transferable unit data, only one power supply and distribution unit record is retained. Power supply and distribution units that exist only in the first or second transferable unit data are retained. The power supply and distribution unit information after removing duplicate records is summarized to obtain the transferable unit data, so that the transferable unit data includes all power supply and distribution units that are affected by the re-attachment video and need to be repositioned.

[0058] In an embodiment of the present invention, candidate path expansion data is obtained, including: Determine the correspondence between relocatable units and installable locations; Based on the power supply and distribution unit type, current installation location, and corresponding connection path information in the relocatable unit data, obtain the relocatable locations of the feeder switch function unit, auxiliary power supply unit, protective grounding branch connection position, and access position inside the door panel accessory cabinet from the target distribution cabinet relocatable location data. Based on the matching relationship between the relocatable unit installation type and the relocatable location type, determine the installation location that can support the corresponding relocatable unit. Establish corresponding relationship data based on the spatial position relationship, connection direction relationship, and path connection relationship between the relocatable unit and the relocatable location, forming the correspondence between the relocatable unit and the relocatable location.

[0059] The correspondence between relocatable units and installable locations refers to the positional matching relationship between a relocatable unit and a specific installation location that can be used to install the relocatable unit when the relocatable unit is rearranged inside the target distribution cabinet. This relationship includes the correspondence information between the relocatable unit category, the current installation location, and the target installation location. Based on the correspondence between movable units and installable locations, multiple installation sequence numbers are generated; Installation sequence refers to the installation layout scheme formed by combining multiple relocatable units in a certain order with multiple installable positions. This scheme is used to represent the spatial arrangement of different relocatable units inside the target distribution cabinet. The correspondence between movable units and installable locations is arranged and combined. Different movable units are configured to their corresponding installable locations, generating multiple installation sequence data containing the arrangement order of movable units and the correspondence between their installation locations. Each installation sequence data represents an installation scheme after the movable units are rearranged. Multiple different installation sequence data are summarized to obtain multiple installation sequences.

[0060] The installation order is used as the particle in the particle swarm algorithm; In particle swarm optimization, a particle is a data object used to represent an installation order scheme. Each particle corresponds to a combination relationship between a movable unit and an installable position. Each installation sequence data is converted into particle position data, so that each particle corresponds to a layout combination relationship between a movable unit and an installable position. Multiple particle position data are generated based on multiple installation sequence data, and multiple particle position data are combined into an initial particle set, so that the particle swarm algorithm can perform subsequent path analysis and layout optimization based on the power supply and distribution path change relationship corresponding to different installation sequences.

[0061] Construct an initial particle swarm based on the initial position and initial velocity of the particles; Initial position refers to the installation order data of the particles when the particle swarm optimization algorithm starts calculation. This data represents the installation arrangement relationship of each migrateable unit in the initial state of the particles. Initial velocity refers to the data used in the particle swarm optimization algorithm to represent the direction and magnitude of the change in the particle installation order. This data is used to adjust the process of the particles changing from the current installation order to other installation orders. Initial particle swarm refers to a data set consisting of particles corresponding to multiple different installation orders. This data set contains multiple migrateable unit layout schemes and is used to compare the path states corresponding to different installation orders later. The initial position of each particle is set as the correspondence between the movable unit and the installable position in the corresponding installation sequence. The installation position of each movable unit in the installation sequence is recorded as particle position data. The initial velocity of the particle is set as the moving direction data of the movable unit in the installation sequence to other installable positions. Multiple particle position data and multiple initial velocity data are generated according to multiple installation sequences. The multiple particle position data and the corresponding initial velocity data are combined to form initial particle swarm data, so that the initial particle swarm data contains multiple movable unit layout schemes.

[0062] Based on the installation order of the particles, the power supply and distribution path is updated to obtain candidate power supply and distribution paths; Position update refers to the process of adjusting the installation position of the movable unit inside the target power distribution cabinet according to the installation sequence corresponding to the particle. A new power supply and distribution path is generated by changing the correspondence between the movable unit and the installation position. The candidate power supply and distribution path refers to the power supply and distribution connection line after being adjusted according to the installation sequence corresponding to a certain particle. This path represents the power transmission path formed after the movable unit moves to the new installation position. The migration unit installation position change relationship in the particle position data is mapped to the internal space position of the target distribution cabinet. The corresponding power supply path, protection connection path and power supply and distribution unit connection path are adjusted according to the new installation position of the migration unit. The starting position, ending position and connection direction of the moved path are redefined, while keeping the original electrical connection relationship between the power supply and distribution units unchanged. New power supply and distribution path data is generated according to the updated power supply and distribution unit position relationship to obtain candidate power supply and distribution paths.

[0063] Based on the back-up video, the candidate power supply and distribution paths are processed by unfolding the cabinet mounting surface to obtain candidate path unfolding data.

[0064] Candidate path unfolding data refers to the position data obtained after unfolding the candidate power supply and distribution path in the cabinet mounting surface. This data includes the extension position of the candidate power supply and distribution path in the unfolded plane, the path direction, and the positional relationship with the back-overlay shadow strip.

[0065] The candidate power supply and distribution path data and the back-overlay image data are converted to the same coordinate system of the cabinet mounting surface. Based on the position and direction of the cabinet mounting surface, the spatial lines in the candidate power supply and distribution path are projected onto the installation unfolding surface. The starting position, ending position, path extension direction, and positional relationship with the back-overlay image are preserved. The projected candidate power supply and distribution path and the back-overlay image are positionally correlated. The intersection relationship, side relationship, and coverage relationship between the candidate power supply and distribution path and the back-overlay image are recorded to obtain the candidate path unfolding data.

[0066] For example, taking a certain type of low-voltage distribution cabinet as the target distribution cabinet, when determining the correspondence between relocatable units and installable locations, the relocatable units that need to be repositioned include the feeder switch functional unit, the auxiliary power supply unit, and the door panel accessory access unit. The current installation position coordinates of the feeder switch functional unit are 300 mm in the X-axis direction and 120 mm in the Y-axis direction; the current installation position coordinates of the auxiliary power supply unit are 420 mm in the X-axis direction and 150 mm in the Y-axis direction; and the current access position coordinates of the door panel accessory access unit are 520 mm in the X-axis direction and 80 mm in the Y-axis direction. 0 mm. Based on the target distribution cabinet's available installation locations, the feeder switch functional unit can be installed in two locations: 260 mm and 120 mm in the X-axis direction, and 340 mm and 120 mm in the X-axis direction. The auxiliary power supply unit can be installed in two locations: 400 mm and 150 mm in the X-axis direction, and 460 mm and 150 mm in the X-axis direction. The door panel accessory access unit can be installed in two locations: 500 mm and 80 mm in the X-axis direction, and 560 mm and 80 mm in the X-axis direction. Next, the movable units are combined with their corresponding installable positions to generate installation sequence 1: the feeder switch functional unit is moved to 260 mm in the X-axis direction and 120 mm in the Y-axis direction, the auxiliary power supply unit is moved to 400 mm in the X-axis direction and 150 mm in the Y-axis direction, and the door panel accessory access unit is moved to 500 mm in the X-axis direction and 80 mm in the Y-axis direction; installation sequence 2: the feeder switch functional unit is moved to 340 mm in the X-axis direction and 120 mm in the Y-axis direction, the auxiliary power supply unit is moved to 460 mm in the X-axis direction and 150 mm in the Y-axis direction, and the door panel accessory access unit is moved to 560 mm in the X-axis direction and 80 mm in the Y-axis direction. Installation sequence 1 and installation sequence 2 are treated as two particles in the particle swarm optimization algorithm. The installation position relationship corresponding to the particles is converted into initial particle position data. Initial velocity data is set according to the direction of installation position change to construct an initial particle swarm containing two particles. The power supply and distribution path is adjusted according to the installation sequence corresponding to the particles. The original connection path of the feeder switch functional unit is adjusted from 300 mm to 260 mm in the X-axis direction, and the connection path of the auxiliary power supply unit is adjusted from 420 mm to 400 mm in the X-axis direction. The unfolded position of the power supply and distribution path is re-determined to obtain candidate power supply and distribution path data. Based on the coverage area of ​​the back-overlay tape on the mounting surface inside the cabinet, the candidate power supply and distribution path is unfolded and analyzed to obtain candidate path unfolded data.

[0067] This step identifies power distribution units affected by strand breakage and reconnection by counting the number of surrounding paths and the number of through paths, and performs deduplication on the first and second movable units. This reduces invalid adjustment objects caused by repeated identification and improves the accuracy of subsequent layout optimization object determination. At the same time, particles in the particle swarm optimization algorithm are generated based on the movable units, and different installation sequences are converted into candidate path expansion data. This allows for the quantitative analysis of the power distribution path status corresponding to different layout schemes, providing a data foundation for subsequent optimization algorithms to screen installation schemes that reduce the impact of reconnection areas and path losses. This solves the problem in existing technologies that rely on manual experience to adjust the position of units inside the distribution cabinet, making it difficult to comprehensively consider the impact of strand breakage and reconnection areas.

[0068] S4. Based on the branch operating current data and candidate path expansion data of the target distribution cabinet, the initial particle swarm is iteratively updated to determine the globally optimal installation order. In embodiments of the present invention, determining the globally optimal installation order includes: Determine the number of circumferential paths and cross-paths in the candidate path expansion data; Spatial relationship analysis is performed between the expanded positions of candidate power supply and distribution paths in the candidate path expansion data and the expanded area of ​​the back-over-the-shadow zone. The path type is determined based on the positional relationship between the centerline of the candidate power supply and distribution path and the boundary of the back-over-the-shadow zone. When the power transmission path and protection connection path of the candidate power supply and distribution path are located on both sides of the back-over-the-shadow zone, the corresponding path is marked as a belt-enclosing path. When the candidate power supply and distribution path passes through the expanded area of ​​the back-over-the-shadow zone, the corresponding path is marked as a belt-crossing path. After completing the type marking for all candidate power supply and distribution paths in the candidate path expansion data, the number of belt-enclosing path markings and the number of belt-crossing path markings are counted to obtain the number of belt-enclosing paths and the number of belt-crossing paths in the candidate path expansion data.

[0069] Based on the candidate power supply and distribution paths, obtain the branch conductor length data; For each branch connection line in the candidate power supply and distribution path, the path endpoints are located to determine the starting and ending positions of the branch conductor connection. Based on the path extension trajectory of the candidate power supply and distribution path after unfolding on the cabinet mounting surface, the length of the conductor path between the starting and ending positions is calculated. The actual extension length of each branch conductor is recorded, and the length of each branch conductor is associated with the corresponding power supply and distribution unit number to obtain the branch conductor length data.

[0070] Obtain the branch operating current data of the target distribution cabinet; Branch conductor length data refers to the actual extension length of each branch conductor in the candidate power supply and distribution path from the connection start point to the connection end point. This data is used to represent the space occupation of the corresponding conductor after the power supply and distribution path is adjusted. Branch operating current data refers to the current magnitude of each branch in the target distribution cabinet flowing through the conductor under normal power supply conditions. This data is used to represent the power transmission load status corresponding to different power supply and distribution paths. The branch detection location is determined based on the electrical connection relationship between each power supply and distribution unit inside the target distribution cabinet. The current acquisition device is connected to the current transmission location corresponding to each branch conductor. Under the normal power supply state of the distribution cabinet, the working current value in each branch conductor is collected. The collected working current value is associated with the corresponding power supply and distribution unit according to the branch number. The working current magnitude of each branch is recorded to obtain the branch working current data of the target distribution cabinet.

[0071] The additional loss proxy is calculated based on the branch operating current data and branch conductor length data. The conductor length data of each branch in the candidate power supply and distribution path is correlated with the corresponding branch operating current data. Based on the proportional relationship between conductor length and conductor resistance, the branch conductor length data is converted into a conductor length influence quantity. The current influence quantity is determined based on the branch operating current data. The conductor length influence quantity and the current influence quantity are multiplied to calculate the additional loss proxy quantity for each branch. The additional loss proxy quantity is calculated by multiplying the square of the branch operating current by the branch conductor length data. The product result is used as the additional loss evaluation data for that branch. The additional loss evaluation data of all branches in the candidate power supply and distribution path are accumulated to obtain the additional loss proxy quantity corresponding to the candidate power supply and distribution path.

[0072] It should be noted that the calculation of the additional loss proxy amount is based on the fact that the change in conductor length after the adjustment of the power supply and distribution path inside the distribution cabinet will directly affect the conductor resistance. The change in conductor resistance will cause the loss during the power transmission process. Therefore, the change in conductor resistance is determined based on the branch conductor length data, and the change in current loss of the corresponding branch is determined in combination with the branch operating current data. By accumulating the current loss of each branch, the additional loss proxy amount reflecting the extra energy consumption caused by the change in the installation position of the candidate power supply and distribution path is obtained. This data can characterize the degree of impact of the change in the length of the power supply and distribution path after the adjustment of different installation positions on the energy consumption of the distribution cabinet.

[0073] The fitness is calculated based on the number of belt paths, the number of belt paths, and the additional loss proxy. Additional loss proxy refers to data that reflects the impact of additional energy loss caused by changes in the installation location of the power supply and distribution path. This data is determined based on the branch operating current data and the branch conductor length data, and is used to evaluate the changes in power supply and distribution path loss corresponding to different installation sequences. Fitness refers to data that evaluates the quality of the installation sequence corresponding to the particle. This data is determined based on the number of surrounding paths, the number of through paths, and additional loss proxy, and is used to indicate the effect of the current installation sequence on reducing the impact of back-overlap and reducing additional losses. The number of surrounding paths, the number of crossing paths, and the additional loss proxy quantity in the candidate path expansion data are normalized to convert different types of data into comparable evaluation quantities. The number of surrounding paths and the number of crossing paths are summed to obtain the back-loop impact evaluation quantity. The back-loop impact evaluation quantity is multiplied by the additional loss proxy quantity to obtain the comprehensive impact quantity. The specific calculation process is as follows: the fitness value is equal to the sum of the number of surrounding paths and the number of crossing paths multiplied by the additional loss proxy quantity. The number of surrounding paths represents the number of paths formed by the power supply and distribution path on both sides of the back-loop shadow zone. The number of crossing paths represents the number of paths of the power supply and distribution path passing through the back-loop shadow zone area. The additional loss proxy quantity represents the amount of loss change caused by the change in the length of the power supply and distribution path corresponding to the current installation sequence. Through the above calculation, the candidate installation sequence with more surrounding paths, more crossing paths, and a larger additional loss proxy quantity obtains a larger fitness value. Thus, the optimization effect of different installation sequences is evaluated based on the size of the fitness value.

[0074] It should be noted that the fitness calculation is based on the need to simultaneously reduce path interference corresponding to the broken strand re-loop position and the additional losses caused by the adjustment of the power supply and distribution path during the layout optimization of the distribution cabinet. Therefore, the number of surrounding paths and the number of through paths are used as the re-loop impact evaluation data, and the additional loss proxy amount is used as the energy consumption evaluation data for comprehensive calculation. When the number of surrounding paths and the number of through paths increases, it indicates that there is more spatial intersection between the power supply and distribution path and the re-loop shadow strip, which will increase the possibility that the grounding braided strip broken strand re-loop area will be affected. When the additional loss proxy amount increases, it indicates that the change in the length of the power supply and distribution path corresponding to the current installation sequence causes greater power loss. By multiplying the number of surrounding paths, the number of through paths and the additional loss proxy amount, a fitness that simultaneously reflects the degree of path impact and the degree of energy consumption change is formed, so that the fitness can evaluate the comprehensive optimization effect corresponding to different installation sequences.

[0075] Based on fitness, determine the individual optimal particle and the global optimal particle; The fitness data of the current particle is compared with the fitness data of the particle in the historical iteration process. When the installation order corresponding to the current fitness can obtain a better evaluation result, the current particle position is updated to the individual optimal particle position. The fitness data of all particles in the initial particle swarm are compared, and the position of the particle with the best fitness is determined as the global optimal particle position. The installation order corresponding to the individual optimal particle and the installation order corresponding to the global optimal particle are recorded to provide positional basis for subsequent particle swarm updates.

[0076] Based on the individual optimal particle and the global optimal particle, the initial particle swarm is iteratively updated to obtain the updated particle swarm. The installation order of each particle in the initial particle swarm is used as the current particle position data. Based on the positional differences between the current particle position data and the corresponding individual optimal particle position data, as well as the positional differences between the current particle position data and the globally optimal particle position data, the installation order adjustment direction of the current particle is determined. The current particle position data is updated according to the determined adjustment direction to obtain the updated particle position data. Based on the updated particle position data, the corresponding movable unit installation position relationships are re-determined, generating new candidate power supply and distribution path data. The number of belt-enclosing paths, the number of belt-crossing paths, and the additional loss proxy amount are calculated for the new candidate power supply and distribution path data. The fitness value of the updated particles is further calculated. The fitness value of the updated particle is compared with the fitness value of the corresponding individual best particle. When the fitness value of the updated particle is better than that of the individual best particle, the position data of the updated particle is updated to the new individual best particle. The fitness values ​​of all updated particles are compared to determine the particle with the best current fitness and update the global best particle, thus completing one particle swarm iteration update. It is then determined whether the current iteration count has reached the preset iteration count. If the current iteration count has not reached the preset iteration count, the next iteration update is performed based on the updated particle swarm. When the current iteration count reaches the preset iteration count, the iteration process is stopped, and all particles after the iteration are combined into the updated particle swarm.

[0077] Based on the updated particle swarm, determine the globally optimal installation order.

[0078] The globally optimal installation sequence refers to the layout scheme determined based on the installation sequence of the particle with the highest fitness in the updated particle swarm. This installation sequence represents the optimal combination of positions of the relocatable units after rearranging them inside the target distribution cabinet.

[0079] The installation sequence data corresponding to each particle in the updated particle swarm is obtained. The fitness data corresponding to each particle is compared to determine the particle position with the best fitness evaluation result. The correspondence between the movable unit and the installable position corresponding to the particle is taken as the target layout relationship. The installation position of the movable unit, the power supply and distribution path connection relationship and the corresponding installation sequence in the target layout relationship are recorded to generate the globally optimal installation sequence.

[0080] S5. Based on the globally optimal installation sequence, optimize the layout of the movable units in the target distribution cabinet to obtain the layout result.

[0081] In embodiments of the present invention, obtaining the layout result includes: The target installation location is obtained by parsing the globally optimal installation sequence. Position sequence analysis refers to the process of splitting and identifying the arrangement information in the globally optimal installation position sequence, which is used to determine the target installation position and the corresponding adjustment order of each relocatable unit; the target installation position refers to the specific spatial location inside the target distribution cabinet for installing the relocatable unit, including the functional unit installation area, the auxiliary power supply unit installation area, the protective grounding connection area, and the door panel accessory access area. The arrangement order of the movable units is obtained based on the particle position data in the global optimal installation sequence. Each position code in the particle position data is matched with the installable position data of the target distribution cabinet to determine the target installation position corresponding to each movable unit. The positional relationship of the feeder switch functional unit, auxiliary power supply unit, protective grounding branch connection position and door panel accessory access position in the global optimal installation sequence is decomposed to obtain the target installation position data of each movable unit. Each movable unit is associated with the corresponding target installation position to form the target installation position.

[0082] Generate target position layout instructions based on the target installation location; The target sequence layout instruction refers to executable layout adjustment information generated based on the globally optimal installation sequence. This information describes the location that each movable unit needs to be moved to, the installation relationship after the move, and the power supply and distribution path adjustment relationship. The names of movable units, their original installation locations, and their target installation locations in the target installation location data are organized. The location adjustment information is determined based on the direction and distance of movement of the movable units, and the path adjustment information is determined based on the power supply and distribution connection relationship between the target installation locations. The movable unit movement information and the power supply and distribution path adjustment information are combined to generate a target position sequence layout instruction. The target position sequence layout instruction includes the movable units that need to be adjusted, the corresponding adjusted installation locations, and the adjusted connection relationships, so that the target distribution cabinet can perform layout adjustments according to the target position sequence layout instruction.

[0083] According to the target position sequence layout instructions, the layout of the movable units in the target power distribution cabinet is optimized to obtain the layout result.

[0084] Layout optimization refers to the process of adjusting the spatial distribution of movable units inside the target distribution cabinet according to the target position sequence layout instructions. By changing the installation position of the movable units, the positional relationship between the power supply and distribution path and the back-overlay belt meets the optimization requirements. The layout result refers to the installation status data inside the distribution cabinet formed after the movable unit position adjustment is completed. This data includes the final installation position of the movable units, the power supply and distribution connection relationship, and the corresponding path arrangement relationship.

[0085] Based on the relocatable unit identifiers, original installation location data, and target installation location data in the target sequence layout instruction, determine the relocatable units that need adjustment. Adjust the installation locations corresponding to the feeder switch functional unit, auxiliary power supply unit, protective grounding branch connection position, and door panel accessory access position to move each relocatable unit to the target installation location. Based on the spatial connection relationship between the target installation locations, redetermine the connection direction between the power supply and distribution units. Rearrange the feeder switch functional unit incoming and outgoing line connection paths, the auxiliary power supply unit to door panel accessory power supply path, and the power supply and distribution unit to protective grounding busbar connection path to match the adjusted power supply and distribution path with the target installation location. Based on the positional relationship between the adjusted power supply and distribution path and the back-overlay tape, expand and verify the power supply and distribution path to confirm that the number of surrounding tape paths and the number of through tape paths in the adjusted power supply and distribution path correspond to the optimization results in the target sequence layout instruction. Integrate the adjusted relocatable unit installation locations, power supply and distribution path locations, and protective connection path locations to generate the layout result.

[0086] This step optimizes the layout of movable units within the target distribution cabinet based on the globally optimal installation sequence, converting the optimal layout scheme into actual installation adjustment results. This allows the feeder switch functional units, auxiliary power supply units, and related connection positions to be rearranged according to the optimized spatial relationship, while simultaneously adjusting the power supply and distribution path connection relationship. This reduces positional conflicts between the power supply and distribution path and the broken strand reconnection shadow zone, lowers path intersections and additional losses caused by unreasonable layout, improves the rationality of internal space utilization and operational reliability of the distribution cabinet, and solves the problem in existing technologies that cannot make targeted layout adjustments based on the broken strand reconnection impact area.

[0087] One embodiment of the present invention also provides a low-carbon and energy-saving integrated layout optimization system for power distribution cabinets.

[0088] In this embodiment, the functions of each module / unit are as follows: The re-attachment imaging module obtains the broken strand re-attachment position from the grounding braided strip image inside the target distribution cabinet door; the broken strand re-attachment position is rotated and unfolded to obtain the re-attachment image strip; The path marking module performs cabinet installation surface unfolding processing on the power supply and distribution path of the back-overlay tape and the target distribution cabinet to obtain the number of belt-enclosing paths; and marks the power supply and distribution path to obtain the number of belt-crossing paths. The migration granulation module performs deduplication on the first and second migrateable units based on the number of surrounding paths and the number of through paths to obtain migrateable units; it determines the particles in the particle swarm algorithm based on the migrateable units, and obtains candidate path expansion data according to the installation order of the particles. The particle swarm optimization module iteratively updates the initial particle swarm based on the branch operating current data and candidate path expansion data of the target distribution cabinet to determine the globally optimal installation order.
