[0041] Figure 2 This is a schematic diagram of a feeder network diagram generation device for a distribution network line provided in an embodiment of this application. Detailed Implementation

[0042] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0043] For easier understanding, please refer to Figure 1 An embodiment of a method for generating feeder network diagrams for distribution network lines provided in this application includes:

[0044] Step 101: Generate the topology data of the feeder entering the distribution network through the GIS model of the distribution network line. The feeder topology data includes the entering path, entering equipment and entering type.

[0045] A GIS model is a comprehensive information system for power production management that connects power equipment, substations, transmission and distribution networks, power users, and power loads within a power company. GIS model data is characterized by standardization, efficiency, and reduced workload, generating and acquiring feeder topology data in real time. This topology data includes information on all paths, equipment, and connection relationships of the current feeder, facilitating subsequent map generation and data analysis.

[0046] In addition to information such as the transfer path, transfer device, and transfer type, the feeder topology data can also include other relevant information as needed, including but not limited to this information, which is not limited here.

[0047] Step 102: Based on the topology data of the incoming feeder, the topology data of the outgoing feeder, and the correspondence between the incoming and outgoing feeders, calculate the first connecting path of the preset two-level connecting feeder.

[0048] Further, step 102 includes:

[0049] Based on the feeder topology data, the feeder connection switch on the feeder is obtained, and the path data where the feeder connection switch is located is used as the comparison path data.

[0050] Using the comparison path data as the benchmark, the non-repeating secondary tie switches are obtained according to the topology data of the outgoing feeder and the correspondence between the incoming and outgoing feeders, and the path data where the secondary tie switches are located are statistically analyzed as the first tie path of the preset secondary tie.

[0051] The feeder topology data can also be generated from the GIS model. The specific acquisition process is not limited here, as it is information that can be directly obtained. Pre-set secondary transfer refers to the existence of other connecting paths to transfer loads besides the current transfer path; these paths may be secondary transfer paths. Specifically, based on the comparison path data determined by the receiving connecting switch, the path data of other connecting switches obtained from the feeder topology data and the feeder topology data are compared with the comparison path data. If it is the first non-repeating switch, then it is a segmented switch; moreover, if this segmented switch is the corresponding connecting switch, i.e., a secondary connecting switch, then the path data corresponding to this switch can be counted as the first transfer path. Otherwise, it is not included in the pre-set secondary transfer.

[0052] It should be noted that the method for determining whether a sectionalizing switch is a tie switch is based on feeder topology data analysis. If the obtained sectionalizing switch contains a tie switch flag, then the current sectionalizing switch can be determined to be a tie switch.

[0053] Step 103: Based on the incoming feeder topology data and the preset outgoing feeder primary key set, calculate the second connection path of the preset T-connection.

[0054] Further, step 103 includes:

[0055] Obtain the transfer-in tie switch and the corresponding transfer-in path based on the transfer-in feeder topology data;

[0056] When the number of incoming tie switches is greater than 1, starting from the incoming tie switch, count the segment switches that do not appear repeatedly on the incoming path according to the preset outgoing feeder primary key set, and use the path data where the segment switches are located as the second connection path of the preset T-connection connection.

[0057] It should be noted that if the number of incoming tie switches is 1, and it is the tie switch between the outgoing feeder and the incoming feeder in the current transfer scheme, then the preset T-connection tie switch has no tie path data; only when the number of incoming tie switches is greater than 1 can the tie path be further analyzed.

[0058] Specifically, starting from the transition switch, segment switches are obtained along the transition path. These are compared with all other types of switches along the path, and duplicate switches are removed to obtain the segment switches that do not repeat. Other types of switches include exit switches, tie switches, and ordinary switches.

[0059] Understandably, if the number of non-repeating segment switches on different paths is 0, then the data for that path will not be included in the T-connection; if the number of non-repeating segment switches is greater than 0, then the current path can be counted in the second connection path; finally, the number of the second connection path can be obtained by counting the number of the second connection path.

[0060] Step 104: Render the first and second connecting paths in different colors on the preset feeder group ring network diagram to obtain the connecting feeder group network diagram.

[0061] Further, step 104 includes:

[0062] Generate a preset feeder group ring network diagram based on the feeder topology data;

[0063] The first and second connecting paths are rendered in different colors on the preset feeder group ring network diagram to obtain the connecting feeder group network diagram.

[0064] Understandably, dispatchers can easily and quickly understand the path information of secondary connections and T-connections by viewing the feeder network diagram, allowing users to have a more intuitive understanding of the line transfer status and greatly improving the dispatcher's work efficiency.

[0065] The method for generating feeder network diagrams for distribution networks provided in this application generates incoming feeder topology data through a GIS model. Combined with outgoing feeder topology data and other related information, it can statistically determine the first connecting path of the secondary connection and the second connecting path of the T-connection. After accurately determining the connecting paths, these paths can be rendered and displayed in different colors according to their different characteristics. The resulting feeder network diagram is more intuitive, the data display is more flexible, and it requires no manual maintenance, thus improving the work efficiency of dispatchers. Therefore, this application embodiment can solve the technical problem that the existing technology's display method for transfer data is too rigid, lacks intuitiveness, and is impractical, thereby reducing the work efficiency of dispatchers.
