[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0047] The network topology correction method provided in the embodiment of the present application can be applied to, for example Figure 1 the application environment shown in the figure. Among them, the terminal 102 communicates with the server 104 through the network. The data storage system can store the data that the server 104 needs to process. The data storage system can be integrated on the server 104, or can be placed in the cloud or other network servers. The initial network topology model, the initial wiring vector diagram and the power flow data of the power system can all be stored in the data storage system. Furthermore, the server 104 can directly obtain the initial network topology model, the initial wiring vector diagram of the power system, and the power flow data of the power system at the target time period from the data storage system. Further, the server 104 can determine the data to be corrected of the power system from the initial network topology model and the initial wiring vector diagram based on the power flow data, and correct the initial network topology model based on the data to be corrected to obtain the target network topology model of the power system, and can display the target network topology model through the terminal 102 for technicians to refer to. Among them, the terminal 102 can be, but is not limited to, various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart in-vehicle devices, etc. The portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The server 104 can be implemented by an independent server or a server cluster composed of multiple servers.

[0048] In an exemplary embodiment, as Figure 2 shown, a network topology correction method is provided. Taking the method applied to Figure 1 the server 104 in the figure as an example, it may include the following steps:

[0049] S201, obtain the initial network topology model, the initial wiring vector diagram of the power system, and the power flow data of the power system at the target time period.

[0050] Among them, the initial network topology model can represent the connection mode and organizational structure of each power device in the power system during initial design and construction; the initial wiring vector diagram can represent information such as the connection relationship, signal flow direction, and power supply configuration among the power devices in the power monitoring system; the power flow data can represent the steady-state distribution of voltage and power in the power system, and can include information such as the voltage amplitude and phase angle of each node in the power system, and the active power and reactive power of each branch.

[0051] Exemplarily, the server 104 can directly obtain the initial network topology model, the initial wiring vector diagram of the power system, and the power flow data of the power system during the target period from the data storage system through a communication module or a communication link.

[0052] S202, based on the power flow data, determine the data to be corrected in the power system from the initial network topology model and the initial wiring vector diagram.

[0053] Among them, the data to be corrected can represent the data that needs to be corrected in the initial network topology model, such as the power devices that need to be corrected, and the physical connection relationship between the power-related devices, etc.

[0054] Exemplarily, data such as nodes, connection edges, and logical relationships can be parsed from the initial network topology model first, and graphic elements such as device symbols, connection lines, and vector arrows can be parsed from the initial wiring vector diagram; further, based on the power flow data, the hierarchical relationships of each node and each branch in the power system can be analyzed; finally, based on the analysis results of the power flow data, the data parsed from the initial network topology model and the initial wiring vector diagram are compared, and the data that does not conform to the analysis results of the power flow data is determined as the data to be corrected in the power system.

[0055] S203, based on the data to be corrected, correct the initial network topology model to obtain the target network topology model of the power system.

[0056] Exemplarily, the data to be corrected can be compared with the initial network topology model to identify the change points in the network structure, such as the addition and deletion of power devices and the change of connection relationships, etc.; further, according to the data to be corrected, the device information of the power devices in the initial network topology model can be updated, such as the name, model, and status of the devices, and according to the change of the connection relationship in the data to be corrected, the connection edges in the initial network topology model can be adjusted to ensure that the new connection relationship is consistent with the data to be corrected, and finally, the target network topology model reflecting the current connection layout of the power system is obtained.

[0057] The above network topology correction method provides a data premise for obtaining the change data of the power system topology by acquiring the initial network topology model, the initial wiring vector diagram of the power system, and the power flow data of the power system during the target period. Further, based on the power flow data, the data to be corrected in the power system can be determined from the initial network topology model and the initial wiring vector diagram, providing a basis for accurately implementing topology correction. Furthermore, based on the data to be corrected, the initial network topology model can be corrected to obtain the target network topology model of the power system. This solution provides a basis for obtaining the data of the initial topology structure of the power system by introducing the initial network topology model and the initial wiring vector diagram. Moreover, by introducing the power flow data, it provides a way to determine the data of the topology structure of the power system during the target period. Finally, the accurate correction of the network topology of the power system is realized.

[0058] Based on the above embodiments, the embodiments of the present application further explain the above embodiment S202 in detail. Specifically, the process of determining the data to be corrected in the embodiments of the present application is as follows Figure 3 shown, and specifically includes the following steps:

[0059] S301, Obtain the device data of the power system from the initial network topology model and the initial wiring vector diagram.

[0060] Among them, the device data may include, but is not limited to, the attribute data of each power device and / or the physical connection data between each power device.

[0061] Exemplarily, for the initial network topology model represented by a graph, image processing or pattern recognition technology can be used to identify information such as power device nodes and connection edges. For the initial network topology model represented by a database, the database can be directly queried to obtain information such as power device nodes and connection edges. And, electrical parameters related to power devices (such as the rated voltage, rated current, and power factor of power devices) and connection states (such as the voltage level and phase of connection points) can be extracted from the initial wiring vector diagram through image processing, pattern recognition, or database query technology. Furthermore, the parsed power device nodes can be matched with the extracted wiring vector diagram to obtain complete device data.

[0062] Optionally, during the data matching process, unique identifiers such as device names, models, and locations can be used to ensure the accuracy of the data.

[0063] S302, Based on the power flow data and the preset correction rules, screen out the data to be corrected in the power system from the device data.

[0064] Among them, the data to be corrected includes the first data to be corrected and the second data to be corrected.

[0065] Exemplarily, the power flow data and device data can be input into a correction model, which analyzes and compares the power flow data and device data, and determines the data to be corrected in the power system from the device data; optionally, the correction model includes preset correction rules, and the correction model can analyze the device data based on the preset correction rules.

[0066] In an implementable manner, based on the naming rules in the preset correction rules, the attribute data that does not conform to the naming rules is screened out from the attribute data of each power device as the first data to be corrected; based on the power flow data and the connection rules in the preset correction rules, the physical connection data that does not conform to the connection rules is screened out from the physical connection data between each power device as the second data to be corrected.

[0067] Exemplarily, according to the naming rules in the preset correction rules, the attribute data of each power device can be checked to screen out the attribute data that does not conform to the naming rules, that is, the first data to be corrected. For example, the naming rules include double naming methods (such as Chinese characters + numbers), character specifications (such as no spaces, backslashes, single quotes, double quotes, percentage signs, etc.), Roman numerals, and prohibited characters (such as it is strictly prohibited to use "#" instead of the Chinese character "number"), etc.; and, according to the power flow data, data such as the voltage amplitude and phase angle of each node in the power system can be determined to judge the connection relationship between each node. Further, in combination with the connection rules in the preset correction rules, the physical connection data between each power device can be analyzed and judged, and the physical connection data that does not conform to the connection relationship and connection rules between each node is screened out, that is, the second data to be corrected.

[0068] Optionally, based on the connection rules in the preset correction rules, the physical connection data that does not conform to the connection rules is screened out from the physical connection data between each power device as the intermediate data to be corrected; based on the power flow data and the intermediate data to be corrected, the physical connection relationship between each power device is inferred according to Kirchhoff's law to obtain the second data to be corrected.

[0069] It should be noted that the connection relationship between power devices (such as generators, transformers, circuit breakers, and instrument transformers, etc.) and the main circuit of power devices (such as each distribution circuit, etc.) is connected in accordance with a certain law or order. Correspondingly, the connection rules in the preset correction rules follow the connection relationship between power devices and the main circuit of power devices; Kirchhoff's law includes Kirchhoff's current law and Kirchhoff's voltage law. Kirchhoff's current law: At any moment, for any node in the circuit, the algebraic sum of the currents passing through this node is always equal to zero; Kirchhoff's voltage law: At any moment, along any closed loop in the circuit, the algebraic sum of the voltages on each section of the circuit is always equal to zero.

[0070] In the embodiments of the present application, by introducing device data including the attribute data of each power device and / or the physical connection data between each power device, a data basis is provided for determining the data to be corrected; and by introducing power flow data and preset correction rules, a judgment basis is provided for screening out the data to be corrected.

[0071] Based on the above embodiments, the embodiments of the present application relate to the process after obtaining the target network topology model, such as Figure 4 shown, which specifically includes the following steps:

[0072] S401, based on the initial network topology model and the target network topology model, determine the correction level of the power system.

[0073] Among them, the correction level can represent the update degree of the topological structure of the power system; optionally, the correction level can include level one, level two, and level three. The level one correction level indicates that the topological structure of the power system changes greatly and involves many power devices. The level two correction level indicates that the topological structure of the power system changes relatively greatly and involves more power devices. The level three correction level indicates that the topological structure of the power system changes relatively little and involves fewer power devices.

[0074] Exemplarily, the initial network topology model and the target network topology model can be compared to determine the power devices to be corrected and the connection relationships between the power devices, and determine the number of correction operations; further, the correction level of the power system can be determined according to the ratio of the number of correction operations to the number of devices of the total power devices in the power system; optionally, the correction level can be mapped to the range of the ratio, such as level three: ratio < b, level two: b <= ratio < c, level one: c <= ratio, where c > b.

[0075] Optionally, based on the target network topology model of the power system, update the preset correction rules.

[0076] Exemplarily, the target network topology model can be analyzed, and the regulations that are outside the preset correction rules and are prone to errors can be updated into the preset correction rules to enhance the update effect on the network topology model.

[0077] S402, based on the correction level, output the processing measures for the power system.

[0078] Optionally, the processing measures can include but are not limited to adjusting device operation parameters, replacing damaged components, adjusting circuits, emergency repair, and strengthening inspections, etc.

[0079] Exemplarily, based on the correction level, the severity and urgency of the power system topology change can be determined to output corresponding levels of processing measures, achieving accurate and effective processing, minimizing the impact on the power system, and ensuring the safety and stability of power supply.

[0080] In the embodiments of the present application, by introducing the correction level, a foundation is laid for judging the degree of power system topology update, and finally precise processing measures are taken.

[0081] Based on the above embodiments, this embodiment provides an optional example of a network topology correction method. As Figure 5 shown, the specific implementation process is as follows:

[0082] S501, Obtain the initial network topology model of the power system, the initial wiring vector diagram, and the power flow data of the power system at the target time period.

[0083] S502, Obtain the device data of the power system from the initial network topology model and the initial wiring vector diagram.

[0084] Among them, the device data includes the attribute data of each power device and / or the physical connection data between each power device.

[0085] S503, Based on the naming rules in the preset correction rules, screen out the attribute data that does not conform to the naming rules from the attribute data of each power device as the first data to be corrected.

[0086] S504, Based on the connection rules in the preset correction rules, screen out the physical connection data that does not conform to the connection rules from the physical connection data between each power device as the intermediate data to be corrected.

[0087] S505, Based on the power flow data and the intermediate data to be corrected, infer the physical connection relationship between each power device according to Kirchhoff's law to obtain the second data to be corrected.

[0088] S506, Based on the first data to be corrected and the second data to be corrected, correct the initial network topology model to obtain the target network topology model of the power system.

[0089] The specific processes of the above S501 - S506 can refer to the description of the above method embodiments, and their implementation principles and technical effects are similar, so they will not be elaborated here.
