[0026] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.
[0027] The following combination Figures 1-8 The present invention describes the method, device and equipment for constructing a provincial map model center based on automatic map driving.
[0028] Figure 1 This is one of the flow charts of the method for constructing a provincial-level model center based on automatic mapping drive provided by the present invention, such as Figure 1 As shown, the method includes the following: Step 101: Obtain power grid models from different sources.
[0029] Specifically, in the embodiment of the present application, power grid models are first obtained from different sources, including PMS / GIS, homologous maintenance systems, marketing systems, and hand-drawn models.
[0030] Step 102: Standardize the power grid models from different sources to generate a power grid public information model based on a single feeder.
[0031] Specifically, after obtaining power grid models from different sources, the embodiments of the present application standardize the power grid models from different sources to generate a power grid public information ICM model based on a single feeder, thereby achieving the unification of model styles from diverse sources.
[0032] Step 103: Generate a single-line diagram and a ring network diagram based on the power grid public information model.
[0033] Specifically, for single-line diagrams, standardization is relatively mature, the process is relatively uniform, and the required splicing time is relatively short. However, considering that ring network diagrams require global model splicing analysis and automatic grouping, the response time is relatively long, which is not conducive to unified and centralized deployment. At the same time, considering that the distribution network master station systems of various cities (districts and counties) have all performed full network splicing when the single-line diagram model is imported, and have passed the scheduling review through the red and black diagram process, the black diagram system model in the distribution network master station database is comprehensive, accurate, timely, and stable. To fully utilize existing resources and existing work, the single-line diagram and ring network diagram drawing functions are deployed separately using two different methods based on their different characteristics. Optionally, the standard power grid feeder CIM model is automatically generated into a single-line diagram, and multiple standard power grid feeder CIM models in the municipal range are automatically analyzed to form a feeder group. These feeder group models are then used to generate a ring network diagram, and the single-line diagram and ring network diagram are converted into graphic formats required in various fields, such as standard CIM / SVG graphics, CIMG format graphics, etc., to realize the construction of a provincial graphic model center driven by automatic drawing.
[0034] The method of the above embodiment addresses the problem of multiple model sources and inconsistent styles. It uses automatic drawing technology as a graphic empowerment tool to quickly generate single-line diagrams with consistent, simple and clear styles, as well as ring network diagrams that meet the requirements of cities and prefectures. It greatly improves the efficiency of diagram and model maintenance work, outputs various graphic formats that meet the requirements, and realizes the efficient and accurate construction of provincial diagram and model centers, meeting the use of various fields such as power monitoring and operation, and generating huge application value.
[0035] In some embodiments, generating a single-line diagram according to a power grid common information model includes: The outgoing substation in the power grid public information model is used as the model starting point to conduct a topological search and generate a model skeleton. The end point of the topological search is the feeder distribution network side contact point or the line end. According to the model skeleton, the open-loop layout and routing of the tree model is obtained; Generate a single line diagram with self-loops based on the open-loop layout and routing of the tree model.
[0036] Specifically, in the embodiment of the present application, in the process of generating a single-line diagram, the outgoing substation of a single feeder is first used as the model starting point, and a topological search is performed until the feeder distribution network side contact point or the line end is reached to extract the model skeleton. Then, based on the skeleton extraction output, an open-loop layout is performed in the direction of the trunk to obtain an open-loop layout and wiring of the tree model. Finally, based on the open-loop layout and wiring, secondary wiring is performed to generate a complete single-line diagram layout with self-loops, thereby achieving efficient and accurate construction of the single-line diagram.
[0037] In some embodiments, obtaining an open-loop layout and routing of a tree model based on a model skeleton includes: Step a: Delete the target feeder segment in the model skeleton to obtain the open-loop layout and routing of the tree model; the target feeder segment is the feeder segment that constitutes the ring topology structure.
[0038] Specifically, in the embodiment of the present application, during the process of generating a single-line diagram, based on the skeleton extraction output, open-loop layout and routing in the trunk direction (the trunk direction is the default direction or the user-specified direction) is performed. It is necessary to first remove the feeder segments that form the ring, and then form a tree structure to perform open-loop layout and routing of the tree model. That is, the feeder segments that form the self-loop feeder ring structure are first extracted, and the remaining models are open-loop layout and routing. The advantage is that it conforms to the characteristics of a larger ring structure. The extracted feeder segments do not have other important electrical equipment (such as switches and distribution transformers), and the turning is more flexible without affecting the overall layout effect, thereby effectively improving the construction efficiency of the single-line diagram and achieving efficient and accurate construction of the single-line diagram.
[0039] The method of the above embodiment, in the process of generating a single-line diagram, is based on the skeleton extraction output, first extracts the feeder segments that constitute the self-loop feeder ring structure, and performs open-loop layout and routing on the remaining models, thereby effectively improving the construction efficiency of the single-line diagram and realizing efficient and accurate construction of the single-line diagram.
[0040] In some embodiments, generating a single-line diagram with self-loops based on an open-loop layout and routing of a tree model includes: Generate a single line diagram with self-loops based on the open-loop layout and routing of the tree model and the target feeder segment; the target feeder segment is the feeder segment deleted in step a.
[0041] Specifically, in this embodiment of the present application, after generating an open-loop layout, the previously removed feeder segments are rerouted to generate a complete single-line diagram layout with self-loops, achieving automatic arrangement of self-loop feeders. Optionally, after constructing the single-line diagram, the layout can be re-arranged based on the above method according to the new trunk direction specified by the user until a trunk direction single-line diagram that satisfies the user is generated.
[0042] In the method of the above embodiment, during the generation process of the single-line diagram, the feeder segments constituting the ring structure of the self-loop feeder are first extracted, the remaining models are open-loop layout and wiring are performed, and then the extracted feeder segments are secondary-wired to complete the automatic arrangement of the self-loop feeder. The advantage is that it conforms to the characteristics of a larger ring structure. The extracted feeder segments do not have other important electrical equipment (such as switches and distribution transformers), and the turning is more flexible without affecting the overall arrangement effect, which effectively improves the construction efficiency of the single-line diagram and realizes efficient and accurate construction of the single-line diagram.
[0043] In some embodiments, generating a single line diagram with self-loops based on the open-loop layout and routing of the tree model and the target feeder segment includes: According to the starting point and the end point of the target feeder segment, an available routing path from the starting point to the end point is determined; Merging and reshaping the paths in the available routing paths to obtain updated available routing paths; Generates a single line diagram with self-loops based on the updated available routing paths and open-loop layout routing of the tree model.
[0044] Specifically, in an embodiment of the present application, after generating the open-loop layout and routing of the tree-like model, the open-loop layout and routing information is obtained, including the positions occupied by stations and equipment and the positions occupied by wiring, the two-dimensional plane is initialized to form a sparse grid, and the obstacle blocks are marked, that is, the positions occupied by stations, equipment, and wiring are marked as 1, and the remaining available space is marked as 0. Then, in the remaining self-loop lines after the open-loop layout is completed, a self-loop feeder segment is selected, the starting point and end point of the self-loop feeder segment are found, and the available routing path from the starting point to the end point is found according to the depth-first search algorithm. Finally, the directions are merged and modified on the basis of the available routing paths to reduce corners and form the routing path of the self-loop feeder segment. Optionally, the path directions in the available routing paths are merged and modified, including merging multiple small stepped routings into one large stepped routing to make it conform to the characteristics of the larger ring structure, thereby improving the beauty and accuracy of the single-line diagram.
[0045] The method of the above embodiment determines the available wiring path from the starting point to the end point based on the starting point and end point of the target feeder segment, merges and transforms the path directions in the available wiring path to obtain an updated available wiring path, and generates a single-line diagram with self-loops based on the updated available wiring path and the open-loop layout wiring of the tree model, so that the generated single-line diagram conforms to the characteristics of a larger ring structure, effectively improving the beauty and accuracy of the single-line diagram.
[0046] In some embodiments, generating a ring network diagram according to a power grid common information model includes: Step x: obtaining a first feeder in the power grid public information model; the first feeder is any feeder in the power grid public information model; Step y: forming a first feeder set based on the first feeder; Step z: adding the second feeder to the first feeder set, and updating the first feeder set; the second feeder and the feeders in the first feeder set exist in the same plant or node; Repeat step z until the first feeder set no longer changes, and generate a ring network diagram.
[0047] Specifically, in an embodiment of the present application, first, a standardized power grid public information model is obtained, that is, all single-line models in the region that have completed the red-to-black transition after the output of the model standardization module are obtained to form a feeder set. The feeder model is then quality checked and verified, and the verification results are displayed to the user in a text list. If the verification fails, the updated feeder model is obtained again. Finally, the ring network groupings in the region are automatically analyzed based on the topological connection relationship, a ring network grouping list is generated, and displayed to the regional dispatcher. The regional dispatcher manually confirms or changes the ring network grouping list based on usage habits, and based on the confirmed grouping list, a usable ring network diagram is automatically generated for each ring network group, and is available for modification and review by the user.
[0048] Optionally, in the embodiment of the present application, the ring network groups in the area are automatically analyzed according to the topological connection relationship. The main process is as follows: (1) For all power plants / T-nodes in the region, a one-to-many mapping is established between the power plants and their connected feeder segments. For power plants / T-nodes that are connected to two or more feeder segments and belong to different feeders, they are marked as cross-feeder power plants / T-nodes.
[0049] (2) Select a feeder (i.e., the first feeder) from the unprocessed feeder set in the area to form a feeder set.
[0050] (3) For each cross-feeder plant / T node on the feeder, place it into the plant type filter to be processed.
[0051] (4) The cross-feeder plant / T node to be processed is searched for another feeder (i.e., the second feeder) that is not in the current feeder set and is added to the feeder set.
[0052] (5) In the feeder set, randomly select a feeder and repeat the above steps until the feeder set no longer changes.
[0053] (6) Output the current feeder set as a ring network group, and repeat the above steps until all feeders in the area are processed. Then all the ring network groups output are the ring network analysis results.
[0054] It should be noted that the method for drawing the ring network diagram at the municipal level in the embodiment of the present application does not rely on the ring network grouping topology analysis method of the connecting switch marking, that is, it does not rely on the additional marking of the connecting switch, but relies on the topological structure of the power grid, thereby avoiding the maintenance cost of manual marking, and the efficiency and accuracy are also higher.
[0055] The method of the above embodiment relies on the topology of the power grid to generate the ring network diagram, rather than relying on additional labeling of tie switches, thereby effectively avoiding the maintenance cost of manual labeling and improving the efficiency and accuracy of ring network diagram generation.
[0056] For example, this application proposes a method for constructing a provincial model center based on automatic mapping drive, as follows Figure 2 The system is divided into four modules: a model standardization module 10, a provincial unified single-line diagram module 20, a municipal-level ring network diagram module 30, and a unified graphics publishing module 40. The model standardization module standardizes models from various sources, including PMS / GIS, homologous maintenance systems, marketing systems, and hand-drawn models, into a grid CIM model based on a single feeder. The provincial unified single-line diagram module and the municipal-level ring network diagram module are the core of the automated graphics center. Automated graphics, from model quality inspection, model splicing, automatic generation, to model output, involve a lengthy, multi-step process. Any intermediate step in this process can lead to failure. Model splicing is a time-consuming bottleneck in this process. For single-line diagrams, standardization is relatively mature, the process is relatively unified, and splicing time is relatively short. However, given that ring network diagrams require global model splicing analysis and automatic grouping, the response time is long, making them unsuitable for centralized deployment. Furthermore, the single-line diagram model import process has already been fully integrated into the distribution network master station systems of all cities (districts and counties), and the red-black diagram process has been approved by the dispatcher. Therefore, the black diagram system model in the distribution network master station database is comprehensive, accurate, timely, and stable. To fully utilize existing resources and existing work, the single-line diagram and ring network diagram generation functions are deployed separately in two different ways, based on their different characteristics. The single-line diagram generation module 20 is responsible for automatically generating a single-line diagram from the standard grid feeder CIM model output by the model standardization module 10. The prefecture-level ring network diagram generation module 30 is responsible for automatically analyzing the topology of multiple standard grid feeder CIM models within the prefecture-level category output by the model standardization module 10 to form feeder groups, and then generating ring network diagrams from these feeder group models. The unified publishing module 40 receives the graphical outputs from the single-line diagram generation module 20 and the ring network diagram generation module 30 and converts them into the required graphic formats for various fields, such as standard CIM / SVG graphics and CIMG format graphics.
[0057] Combined with the trunk direction specified by the user, based on the open-loop layout and routing, the single-line diagram automatic generation method of the self-loop routing optimization algorithm is as follows: Figure 3 The steps are: (1) Taking the outgoing substation of a single feeder as the model starting point, a topology search is performed until the feeder distribution network side contact point or the end of the line is reached to extract the model skeleton; (2) Based on the skeleton extraction output, open-loop layout and routing are performed in the trunk direction (the trunk direction is the default direction or the user-specified direction). That is, the feeder segments that constitute the ring are first removed to form a tree structure, and the open-loop layout and routing of the tree model is performed.
[0058] (3) Based on the generated open-loop layout, the previously removed feeder segments are re-routed to generate a complete single-line diagram layout with self-loops.
[0059] (4) According to the new trunk direction specified by the user, go to step (2) and start the arrangement again until a trunk direction single-line diagram that satisfies the user is generated.
[0060] Optimization algorithms for self-loop routing, such as Figure 4 The steps are: (1) Obtain open-loop layout and wiring information, including the locations of stations and equipment, and the locations occupied by wiring; (2) Initialize the two-dimensional plane to form a sparse grid.
[0061] (3) Mark the obstacle block, that is, mark the location occupied by the station, equipment, and wiring as 1, and mark the remaining available space as 0; (4) Select a self-loop feeder segment from the remaining self-loop lines after the open-loop layout is completed. If there is no self-loop feeder segment that has not been processed, go to step (7).
[0062] (5) In the grid, find the starting point and end point of the self-loop feeder segment, and find the available routing path from the starting point to the end point according to the depth-first search algorithm.
[0063] (6) Based on the available routing paths output in step (5), the routing paths are merged and modified to reduce the corners, thus forming the routing path of the self-loop feeder segment. Then go to step (3).
[0064] (7) The self-loop wiring is completed.
[0065] The method of drawing ring network diagram at prefecture-level, such as Figure 5 The steps are: (1) Obtain all single-line models after red turns black in the area to form a feeder set; (2) Perform quality inspection and verification on the feeder model, and display the verification results to the user in a text list. If the verification fails, return to step (1) and re-obtain the updated feeder model.
[0066] (3) Automatically analyze the ring network groups in the area based on the topological connection relationship, generate a ring network group list, and display it to the regional dispatcher; (4) Regional dispatchers manually confirm or modify the ring network grouping list based on usage habits.
[0067] (5) Based on the confirmed group list, each ring network group automatically generates a usable ring network diagram for users to modify and review.
[0068] The method for drawing the ring network diagram at the prefecture-level, in which step (3) does not rely on the ring network group topology analysis method marked by the tie switch, such as Figure 6 The steps are: (1) For all power plants / T-nodes in the region, a one-to-many mapping is established between the power plants and their connected feeder segments. For power plants / T-nodes that are connected to two or more feeder segments and belong to different feeders, they are marked as cross-feeder power plants / T-nodes.
[0069] (2) Select a feeder from the unprocessed feeder set in the area to form a feeder set.
[0070] (3) For each cross-feeder plant / T node on the feeder, put it into the plant type filter that needs to be processed. If the filter result is that it needs to be processed, go to the next step; otherwise, discard it and do not need to be processed.
[0071] (4) For the cross-feeder plant / T node to be processed, find the other feeders that are not in the current feeder set and add them to the feeder set.
[0072] (5) In the feeder set, randomly select a feeder and repeat step (3) until the feeder set no longer changes.
[0073] (6) Output the current feeder set as a ring network group, and repeat steps (2) to (5) until all feeders in the region are processed; then all the output ring network groups are the ring network analysis results. The city-level ring network diagram drawing method and the ring network group topology analysis method that does not rely on the tie switch marking, in which step (3) the plant station type filter to be processed can be configured according to the needs of different city users, with options such as processing distribution room type, not processing distribution room type, and processing distribution room type when a single feeder is not connected. This is because medium-voltage distribution rooms often cannot become the contact point for line transfer. Different strategies are adopted to adapt to the different understandings and different uses of topological connections by users in different regions.
[0074] The present application discloses a method for constructing a provincial map model center based on automatic mapping drive, wherein a model standardization module standardizes models from different sources into a power grid CIM model based on a single feeder line. The different sources include PMS / GIS, homologous maintenance systems, marketing systems, and hand-drawn models. The provincial unified single-line diagram drawing module and the municipal-level ring network diagram drawing modules are the core of the map model center. The single-line diagram drawing module is responsible for automatically generating a single-line diagram from the standard power grid feeder CIM model. The municipal-level ring network diagram drawing module is responsible for automatically analyzing the topology of multiple standard power grid feeder CIM models within the municipal range to form a feeder group, and then generating a ring network diagram from these feeder group models. The unified graphic publishing module receives the graphic output of the single-line drawing module and the ring network diagram drawing module, and converts them into the graphic formats required in various fields, such as standard CIM / SVG graphics, CIMG format graphics, etc. In order to solve the problems of diverse graphic sources, inconsistent styles, and multiple model sources, the present invention uses automatic drawing technology as a graphic empowerment tool, which can quickly generate single-line diagrams with consistent style, simple and clear style, and ring network diagrams that meet the requirements of cities and prefectures. It can greatly improve the efficiency of graphic model maintenance work, output various graphic formats that meet the requirements, and provide them for use in various fields of power monitoring and operation.
