[0002] With the continuous development of technology, the scale of distribution networks is increasing, and the number of power grid devices within them is also increasing.

[0041] In order to help those skilled in the art better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0042] For easier understanding, see Figure 1 , an embodiment of a method for generating a distribution diagram of line switches in a distribution network provided by the present application includes:

[0043] Step 101: Generate feeder topology data based on a preset GIS model of the distribution network. The feeder topology data includes switch paths, switch inflection points, and basic equipment information.

[0044] Pre-built GIS models are used to describe information such as distribution network equipment, feeders, substations, power stations, power supply bureaus, connections, and subordinate relationships. They are standardized, efficient, and reduce workloads. The switch paths and inflection points in the feeder topology data can be used to determine the precise location of relevant equipment, while basic equipment information can be used to obtain specific equipment operating parameters. Using these location and parameter information, a switch distribution map can be determined for the entire distribution network. Basic equipment information primarily refers to information such as device descriptions and types, while topology data includes specific device connection relationships.

[0045] Step 102: Perform classification operations, grid division, and coordinate calculation according to the feeder topology data to obtain the coordinate position of the device.

[0046] Furthermore, step 102 includes:

[0047] A switch path category analysis is performed on the feeder topology data to obtain a category switch path, which includes a single switch path and a multi-switch path.

[0048] A single-switch path means that the current path has only one switch, and this switch does not belong to a station building; a multi-switch path means that the current path has two or more switches, or has only one switch and this switch belongs to a station building.

[0049] The distribution network is gridded based on the category switch paths to obtain multi-switch line rows.

[0050] Calculate the coordinates of the line equipment based on the multi-switch line row to obtain the device coordinate position. The specific calculation process is as follows: In the preset coordinate two-dimensional coordinate system, calculate the coordinates from top to bottom and from left to right. Each multi-switch path is a row. The height interval between each row is fixed. The width interval between switches in each row is fixed. When the switch has an inflection point, the width between the current switch and the next switch increases by the number of inflection points multiplied by the fixed interval. The path where the exit switch is located is in the first row. Based on the connection relationship and inflection point, determine the row where the other multi-switch paths are located. The x-coordinate and y-coordinate of the first row are both 0. First calculate the coordinates of all switches in the first row. The starting coordinates of each row of other rows are determined based on the inflection point. Then calculate the switch coordinates of each row, and then obtain the coordinates of all switches.

[0051] Furthermore, the coordinates of the line equipment are calculated according to the multi-switch line row to obtain the equipment coordinate position, and then the method further includes: performing an updating and optimizing operation on the equipment coordinate position based on the switch inflection point to obtain the updated equipment coordinate position.

[0052] Feeder topology data is statistically analyzed for devices and lines, and all switch paths are classified into two main categories: single-switch paths and multi-switch paths. The grid division operation relies on the switch path classification. Specifically, multiple preset rows are divided according to a preset fixed height, and then the multi-switch path is defined as a row, while the single-switch path does not occupy the preset row, thus forming a multi-switch line row. The topological connection relationship described in the multi-switch line row and feeder topology data can determine the specific device location. Based on the preset grid-fitting coordinate system, the specific relative position coordinates, i.e., the device coordinate position, can be calculated.

[0053] In order to avoid the intersection and overlap of switches and other devices on the line, the coordinate position of the device also needs to be updated and optimized. The parameters or mechanisms based on them may be different. For example, in this embodiment, the coordinate position of the device is updated and optimized based on the switch inflection point. In this process, according to the switch inflection point positions recorded in the topology data, multiple inflection points in the same row are merged into one row, and redundant rows are removed. Specifically, if the last switch in each row has multiple inflection points, the path width corresponding to the last inflection point is calculated. If the width of the current path plus the path width corresponding to this inflection point is less than the set width limit, the path corresponding to the last inflection point is moved to the end of the current path. After updating the multi-switch line row, the coordinate position of the device is updated at the same time to obtain the updated device coordinate position. Such coordinate optimization can not only obtain the local switch distribution situation, but also summarize the global switch distribution characteristics, which is more targeted.

[0054] In addition to the above optimization methods, it is also possible to calculate the horizontal coordinate span of each multi-switch line row, and merge rows and delete empty rows without causing intersections. Specifically, if there are two or more inflection points at a switch, calculate the path widths corresponding to all inflection points and the rightmost x-coordinates of the paths, perform a loop traversal, and start from the rightmost inflection point. Traverse all inflection points from right to left in sequence. Select two inflection points for calculation each time. The rightmost x-coordinate of the path of the previous inflection point plus the path width of the next inflection point, if it is not greater than the set width limit, move the next inflection point path to the row where the previous inflection point path is located. After moving, if there is no other path information in the next row, delete the current empty row, and then update the coordinate position of the computing device at the same time.

[0055] Alternatively, the coordinates of each multi-switch line are calculated relative to the leftmost and last edges, and rows that can be moved are found and merged, eliminating any unused rows. Specifically, if a row path moves upward and does not intersect with the path of the row it is moving to (that is, the leftmost and rightmost x-coordinates of the two paths do not intersect), it can be moved to that row. The resulting unused rows are then eliminated, and the process continues by moving upward one row at a time, iterating through a loop until the row with the smallest y-coordinate is reached. If an intersection occurs, the loop is exited. Similarly, the coordinate position of the computing device is updated while optimizing the multi-switch line.

[0056] Based on the above-obtained device coordinate positions and the topological connection relationship in the feeder topology data, the distribution of switches can be determined to form a specific architecture diagram.

[0057] Step 103: Acquire topology-related parameters of the distribution network in real time based on the feeder topology data. The topology-related parameters include the number of distribution transformers, the number of users, the current value, and the switch closing state.

[0058] Furthermore, step 103 includes:

[0059] Based on the feeder topology data, real-time statistics are collected on the number of distribution transformers associated with each switch in the distribution network, and the number of users associated with each switch. The number of users includes the total number of users and the number of medium-voltage users.

[0060] The current value and switch closing status of each switch in the distribution network are loaded in real time according to the feeder topology data.

[0061] Specifically, it means: performing distribution transformer statistics on feeder topology data, starting from the distribution transformer and searching towards the outlet switch. When encountering the first switch, the total number of downstream distribution transformers corresponding to the switch and the number of distribution transformers between the switch and the nearest downstream switch are both increased by 1. When encountering other switches, only the total number of downstream distribution transformers corresponding to the switch is increased by 1. Based on the feeder topology data, the primary key of each distribution transformer is counted, and by querying the marketing data, the number of low-voltage users and medium-voltage users associated with each distribution transformer is queried.

[0062] The above-formed architecture diagram, when supplemented with parameters related to the equipment operating in the distribution network, becomes a complete switch distribution diagram, providing more detailed and reliable information. The number of distribution transformers includes the total number of distribution transformers downstream of each switch, as well as the number of distribution transformers between the nearest downstream switch. The number of users includes the total number of users associated with each switch, including the number of medium-voltage users, or the specific number of low-voltage users. User numbers should also be recorded to facilitate subsequent data analysis. Data statistics are selected based on actual circumstances and are not limited to the ones described here.

[0063] Feeder topology data is categorized and counted, and the primary keys of all switches are collected. Based on the primary keys, the current value and switch closure status corresponding to each switch are obtained from the metering system. This parameter information ensures that the architecture diagram is both real-time and reliable.

[0064] Step 104: Generate a target line switch distribution map of the distribution network based on the device coordinate positions and topology-related parameters using SVG technology.

[0065] Using SVG technology, topology-related parameters can be loaded into a distribution map constructed from device coordinate positions, creating a switch distribution map in SVG format. The target line switch distribution map is strictly layered, specifically divided into substation layers, switch layers, text layers, and connection line layers. Different devices are drawn in different layers, allowing for convenient configuration of different functions for each layer. Furthermore, different display colors can be set for different layers as needed. Information such as switches, connection lines, and text can all be clearly viewed, with a clear layout and real-time display. This information requires no manual maintenance and can meet both global and local switch distribution map viewing requirements. The viewing process is described as follows: The zoom factor is first calculated based on the set ratio value, browser type, and distribution map window size, and then the target line switch distribution map is viewed based on the zoom factor.

[0066] The method for generating a distribution network line switch distribution map provided by the embodiment of the present application can calculate the specific coordinates of each device based on the feeder topology data generated by the GIS model; then obtain the topological parameters of the distribution network in real time, such as the number of distribution transformers, the number of users, and other information; finally, combine the location information and parameter information to obtain a real-time updated target line switch distribution map; no additional maintenance work is required, and the switch distribution characteristics on the line can be described in a targeted manner based on the classification and grid division of the distribution network, which is conducive to the global and local viewing of the distribution map. Therefore, the embodiment of the present application can solve the technical problems that the existing distribution network line switch distribution map has a large maintenance workload and cannot adapt to the viewing needs of zooming in and out.
