DETAILED DESCRIPTION

[0011] In the following description, specific details such as specific system structures and technologies are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present disclosure. However, it should be clear to those skilled in the art that the present disclosure may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid obstructing the description of the present disclosure with unnecessary details.

[0012] In order to make the purpose, technical solutions and advantages of the present disclosure more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0013] Please refer to Figure 1 , Figure 1 A schematic flow chart of a method for automatic layout of a main wiring diagram of a substation provided by an embodiment of the present disclosure, the method comprising: S101: Process first data to obtain transformer parameters, where the first data is topological structure data of power grid equipment.

[0014] In this embodiment, the first data is the topological structure relationship data of the power grid equipment, which can be obtained by parsing the CIME (Common Information Model for Electricity) file. The CIME file is a commonly used data structure in the power system, which needs to be parsed to adapt to the automatic layout system data specification definition, read various types of equipment such as transformer equipment, busbar equipment, switch and knife switch equipment, load equipment, etc., parse the topological relationship business data specification, and generate JSON structure data.

[0015] The first data contains information such as the connection relationship, location, type, etc. of various devices in the power grid, among which substation information is very important. By screening the first data, transformer-related parameters such as transformer capacity, rated voltage, current, impedance, cooling method, tap position, etc. are obtained.

[0016] S102: Determine a plurality of busbars and a busbar device corresponding to each busbar, and calculate a first connection relationship line starting from the busbar device based on transformer parameters, the busbar device, and each node.

[0017] In this embodiment, the transformer is one of the core devices in the power system, and its parameters directly affect the stability and safety of the power system. If the transformer parameters are incorrect, it will cause problems such as transformer overload and overheating, thereby accelerating the aging of the equipment and even causing equipment failure. By verifying the transformer parameters, these problems can be discovered and corrected in a timely manner, thereby extending the service life of the equipment. In the automatic layout process of the substation main wiring diagram, the transformer is an important equipment node, and the accuracy of its parameters directly affects the accuracy and efficiency of the layout results. If the transformer parameters are incorrect, it may cause deviations in the layout results, or even fail to generate an effective layout plan. Therefore, verifying the transformer parameters is a key step to improve the accuracy and efficiency of automatic layout. When the verification result of the transformer parameters is correct, the connection relationship lines can be calculated. The specific process is as follows: Determine the busbar and the busbar equipment corresponding to the busbar (i.e. the auxiliary mounting equipment of the busbar). The mounting equipment of the busbar may include grounding switch, circuit breaker, protector, disconnector, etc.

[0018] The voltage levels of the high, medium and low voltage sides of the transformer are obtained according to the transformer parameter information, the busbars and the corresponding auxiliary hanging equipment of each busbar are grouped according to the voltage level, and the associated busbars and other equipment are grouped according to the voltage area. In this way, the busbars and equipment with the same voltage can be at the same voltage level, which is convenient for the analysis and calculation of the power connection relationship.

[0019] Each node refers to each connection point in the power system, which can be the connection point of the bus, equipment or other electrical components. According to the topological structure of the power system, starting from the bus equipment, connecting each node to obtain all connection paths between the starting point and the end point, these connection paths are the first connection relationship lines.

[0020] S103: Based on the first connection relationship line, the busbar equipment and the load equipment are laid out to obtain a first main wiring diagram; based on the first data, the first main wiring diagram is optimized to obtain a target main wiring diagram.

[0021] In this embodiment, first, the buses of each voltage level are grouped and their types are determined based on the first connection relationship line, and different bus types have different layout methods. Secondly, after the bus is grouped and the type is determined, the bus equipment and load equipment need to be laid out to obtain the first main wiring diagram. The specific process is as follows: a. Determine the initial busbar location, calculate the busbar length, determine the busbar connection points, and realize the busbar location layout; b. Busbar interconnection line layout, used for busbar segmentation and busbar bypass, to achieve equipment positioning layout between two busbars; c. Plan the connection lines and equipment layout between the busbar and the transformer, and realize the equipment positioning layout between the busbar and the transformer; d. Location and layout of busbar connection lines, loads and other equipment; e. Calculation of layout of other ancillary equipment.

[0022] According to the above layout method, the equipment layout is completed to obtain the first main wiring diagram. Because the first main wiring diagram has not been defined by the graphic element specification, the online substation main wiring diagram cannot be generated. Therefore, it is necessary to optimize the first main wiring diagram according to the graphic element specification definition, such as code generation, adding animation, etc., to obtain the final substation main wiring diagram, that is, the target main wiring diagram.

[0023] It can be concluded from the above that the embodiment of the present disclosure can quickly and accurately obtain transformer parameters by automatically processing the topological structure data of power grid equipment, thereby effectively improving work efficiency. At the same time, by verifying the transformer parameters, the accuracy of the data is ensured, laying a solid foundation for subsequent layout and optimization work. During the layout process, the present disclosure formulates a standardized definition for the substation line data, calculates the positioning layout based on the transformer-bus-line model distribution topology, analyzes the node deployment design, and realizes the automatic generation of the substation main connection diagram. The present disclosure takes into account the actual system user needs, and uses the State Grid system CAD drawing drawing as a reference to realize a method for automatic layout of the substation main connection diagram, which improves the efficiency of graphics drawing, enriches the display effect of drawing results, and provides support for the actual business system.

[0024] In one embodiment of the present disclosure, a first connection relationship line starting from the bus device is calculated based on transformer parameters, bus devices and each node, including: Determine a first node among the nodes, and calculate a connection path between the starting point and the first node as a first connection relationship line; The first node is a node without subsequent connected nodes.

[0025] The connection path between the calculation starting point and the first node is calculated as a first connection relationship line, including: The starting point is taken as the second node, and the second node is the visited node; Determine a plurality of third nodes adjacent to the second node, where the third nodes are unvisited nodes; Recursively call the depth-first traversal algorithm for each third node and use the third node as the second node; When the first node is the second node, the connection path between the calculation starting point and the first node is the first connection relationship line.

[0026] In this embodiment, the connection relationship line path is calculated based on the depth-first search algorithm of the topological structure. The line path information associated with the node is calculated, the line path is merged and sorted, and short lines are removed to obtain the node connection path.

[0027] The depth-first search algorithm is an algorithm for traversing or searching a tree or graph. The principle is: starting from the starting node (select some arbitrary nodes as the starting node in the case of a graph, and usually the root node in the case of a tree), search as deeply as possible along each branch until the target node is reached or it is impossible to continue, then backtrack to the nearest unexplored node and continue exploring. The core idea of ​​the algorithm is backtracking and pruning, that is, when a path reaches the end, it will backtrack to the previous node and try other unexplored paths.

[0028] refer to Figure 2 ,The specific implementation of the line path calculation method is: take the branches and other nodes contained in the node as a tree with the node as the root, and use the depth-first search method to find all the paths from its root to the end node (the first node), that is: Select a bus device as the starting point, use the starting point as the current node, and mark the current node as visited (that is, if the current node has been visited, it becomes the second node). Traverse all unvisited adjacent nodes of the current node; for each unvisited adjacent node (third node), recursively call the depth-first search algorithm and use the node as the new current node; When all adjacent nodes have been visited, return to the previous layer for recursive calls.

[0029] The paths are sorted by length, and according to the relationship contained in the lines, the corresponding short lines are removed and sorted again, and all the connection paths between the starting point and the end node are calculated for the longest main line determination and the end point branch line determination. All these connection paths are the first connection relationship lines.

[0030] It can be concluded from the above that this embodiment uses a depth-first traversal algorithm to accurately calculate the connection path between the busbar device and the first node without subsequent connection nodes, that is, the first connection relationship line. This method ensures the integrity and accuracy of the layout and effectively avoids omissions or incorrect connections. At the same time, recursively calling the depth-first traversal algorithm improves the layout efficiency, making the automatic layout of the substation main wiring diagram faster and more reliable.

[0031] In one embodiment of the present disclosure, a first main wiring diagram is obtained by laying out busbar equipment and load equipment based on a first connection relationship line, including: If the first connection relationship line includes medium voltage parameters, the busbar equipment is laid out based on the layout mode on the right side of the medium voltage side of the transformer, and the load equipment is laid out to obtain a first main connection diagram; If the first connection relationship line does not include the medium voltage parameter, the busbar equipment is laid out based on the first connection relationship line, and the load equipment is laid out to obtain the first main connection diagram.

[0032] Load equipment includes branch equipment; branch equipment is equipment on branch lines, and branch lines are connected to busbars; The first main connection diagram obtained by arranging the load equipment based on the layout mode on the right side of the medium voltage side of the transformer includes: The branch equipment is laid out based on the layout on the right side of the medium voltage side of the transformer.

[0033] In this embodiment, if the first connection relationship line includes medium voltage parameters, the busbar equipment and load equipment are laid out according to the layout method of vertical layout of high voltage parameter equipment and low voltage parameter equipment and horizontal layout of medium voltage parameter equipment to obtain the first main connection diagram.

[0034] First of all, because different bus types have different layout methods, it is necessary to group and type the buses of each voltage level according to the first connection relationship line, and distinguish the different connection types of single bus, single bus segment, single bus segment with bypass, double bus, double bus segment, double bus segment with bypass, and 3 / 2 connection.

[0035] The judgment rules are as follows: ① Calculate the number of busbars. One busbar is considered a single busbar. The number of busbars = |busbar set|.

[0036] ② In the case of multiple busbars, according to the connection relationship between all busbars and transformers, if the busbars are connected to a transformer at the same time, it is judged as a double busbar, otherwise it proceeds to the subsequent judgment.

[0037] Connection relationship = busbar set ∩ transformer connected busbar set ③Bypass bus determination: according to the interconnection line between buses, if there is a topological connection between buses and the transformer equipment cannot be topologically connected, it is determined to be a bypass bus; otherwise, it is determined to be a single bus segmented line.

[0038] Number of interconnection lines = |Set of interconnection lines between busbars| Number of topological connections = busbar interconnection line set ∩ transformer connection line set ④ Other special types of connections are determined by referring to the corresponding fields of line attributes.

[0039] The busbar equipment and the load equipment are laid out based on the first connection relationship line to obtain the first main wiring diagram, and the process is as follows: ① Calculate all busbars including branch line paths, including: busbar to transformer path, busbar to other busbar paths, and busbar to load equipment path; ②Layout the position of the first high-voltage bus, draw the horizontal extension of the high-voltage bus, calculate the number of bus-to-load paths, set it as the bus length, and the bus interval is the equipment connection interval; Busbar length calculation formula: TotalLength=(busbarToOutLineCount+1)*nodeStep+(busbarCount-1)*nodeStep Among them, TotalLength is the total length of the busbar, busbarToOutLineCount is the number of external connection paths connected to the busbar, busbarCount is the number of busbars, and nodeStep is the preset unit spacing length.

[0040] ③ Draw the path from the busbar to the load equipment upwards. The path interval is the equipment connection interval. Draw the busbar interconnection line and set the angle of each device according to the direction. ④ Draw the path from the busbar to the transformer equipment downward, with the starting point being the center point of the busbar line; ⑤ Repeat the high-voltage side busbar drawing method and continue to draw busbars of other voltage levels, with the low-voltage side drawn downward and the medium-voltage side drawn to the right.

[0041] After the layout of the bus and the equipment corresponding to the bus is completed, you can layout the branch equipment, loop the branch equipment list, search for the main equipment to which it belongs, calculate the branch equipment location and connection direction based on the main equipment location and surrounding occupancy, and set the layout location information.

[0042] In one embodiment of the present disclosure, optimizing the first main wiring diagram based on the first data to obtain a target main wiring diagram includes: Determine a graphic element specification definition based on the first data; The first main wiring diagram is optimized based on the graphic element specification definition to obtain the target main wiring diagram.

[0043] In this embodiment, the first data is the topological structure relationship data of the power grid equipment. The automatic layout rules of the substation main wiring diagram are based on the topological structure relationship data of the power grid equipment. In order to facilitate the normalization of business data and data analysis and processing, it is necessary to formulate the automatic layout system data specification definition in advance. The topological structure relationship data of the power grid equipment includes the graphic element specification definition and the graphic specification definition. The graphic element specification definition refers to the standardized description of the basic elements in the topological structure of the power grid equipment, such as busbars, substations, circuit breakers, disconnectors and other power grid equipment. In addition, the graphic element specification definition also includes the coding of equipment such as substations and connecting lines, graphic style definition, business-related data definition, etc. See Table 1 for details.

[0044] Table 1 Definition of graphic element specifications

[0045] Graphic specification definition refers to the rules and standards for drawing the topological structure diagram of power grid equipment. The content of graphic specification definition may include: Graphical symbols: Assign a unique graphic symbol to each device type for easy identification in the topology diagram. Layout rules: Specify how the devices are laid out in the topology diagram, such as the busbar is usually arranged horizontally or vertically, and generators and transformers are usually placed near the busbar. Color and line type: Assign specific colors and line types to different types of devices and connecting lines for easy distinction and identification. Annotation rules: Specify how to annotate in the topology diagram, such as the name, number, and operating status of the device.

[0046] In addition, the graphic specification definition also includes: point-type power equipment, line-type equipment, and drawing business-related data definitions. Point-type power equipment in the graphic specification definition usually refers to various node devices in the power grid; line-type equipment in the topological structure of power grid equipment mainly refers to various types of connecting lines, such as overhead lines and cables. Drawing business-related data definitions refer to business data and information related to the topological structure diagram of power grid equipment.

[0047] Business data is divided into two types: node and connection relationship. The node type corresponds to node information, and the connection relationship type corresponds to connection information.

[0048] Node information is device information, including device type, associated device information, device number, device name and other extended information (such as device tag information, business attribute information, etc.).

[0049] Connection information is used to identify the connection relationship between devices, that is, node information is device information, including type, associated device information, including number, name and other extended information (such as device tag information, business attribute information, etc.).

[0050] The example format of business data is as follows: { "nodes": [ / / Device information { "type": "Point graphic primitive type, corresponding to the unified point primitive encoding", "devId": "Corresponding ledger device id", "name": "Device name", / / Extended information (other business-related extended information) "extra": {}, }, ], "links": [ / / Connection relationship { "type": "Connection line type", "source": { "id": "Starting point device ID", "port": "The point graphic anchor point connected by the starting point", }, "target": { "id": "Destination device ID", "port": "The point graphic anchor point of the end point connection", }, "devId": "Corresponding ledger device id", "name": "Device name", / / Extended information (other business-related extended information) "extra": {}, }, ] } The first main wiring diagram is optimized based on the graphic element specification definition to obtain a target main wiring diagram, including: The scalable vector graphics code corresponding to each device in the first main wiring diagram is obtained based on the graphic element specification definition, and each device in the first main wiring diagram is optimized based on the scalable vector graphics code to obtain the target main wiring diagram.

[0051] In this embodiment, the location information of each device is obtained according to the first main wiring diagram. The identification method of each device in Scalable Vector Graphics (SVG) is determined based on the graphic element specification definition, and the corresponding SVG code fragment is generated for each device according to the device type and location information and the graphic element specification definition. These code fragments may include <rect> 、 <circle> 、 <line>SVG elements such as , are used to represent the shape and outline of the device. Add <style>元素，定义各种样式规则，如颜色、填充、边框等，这些样式可以呈现设备的外观。使用SVG的动画功能为设备添加动画效果。将所有设备的SVG代码片段、样式定义和动画效果整合到一个完整的SVG文件中。使用SVG验证工具检查生成的SVG文件是否符合SVG标准，确保文件在浏览器中能够正确显示。在前端页面中，使用标签、<object>标签或<iframe>标签等方式引入SVG文件，得到目标主接线图。

[0052] 由上可以得出，本实施例通过制定图元规范定义和图形规范定义，实现了电网设备拓扑结构关系数据的规范化处理，为自动布局系统提供了统一的数据解析标准。同时，利用SVG技术对第一主接线图进行优化，提高了主接线图的绘制效率和准确性，使得目标主接线图更加清晰、直观，便于运维人员快速理解电网设备的连接关系和运行状态。
