[0002] Actively and comprehensively promoting the intelligent and digital transformation of the power system, fully supporting the upgrading and construction of substations, and striving to establish a safe smart grid can improve the reliability of power supply.

[0003] The secondary system of a smart substation transmits station-wide information and implements relay protection functions by using fiber optic links instead of electrical circuits. Currently, the relevant operation and maintenance materials for smart substations include both traditional paper-based drawings and important electronic data such as ICD (IED Capability Description), SCD (Substation Configuration Description), CCD (Configured Circuit Description), and virtual terminal connection tables, which are generated after the electrical circuits are digitized. However, existing ledger and acceptance specifications do not establish corresponding standards for these electronic data.

[0004] In the process of realizing this invention, the inventors discovered the following defects in the prior art: the management of relevant operation and maintenance materials of existing intelligent substations lacks a basis, and since intelligent substations use fiber optic links to replace multiple electrical circuits, it is impossible to grasp the information transmitted internally. There is a lack of "virtual-real correspondence" between the physical transmission circuit and the signal virtual circuit, which reduces the manageability of substation data. Summary of the Invention

[0034] Example 1

[0035] Figure 1 This is a flowchart of a substation secondary system data processing method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations involving the digital processing and visual management of substation secondary system data. The method can be executed by a substation secondary system data processing device, which can be implemented in software and / or hardware, and is generally integrated into an electronic device. This electronic device can be a terminal device or a server device. The present invention does not limit the specific type of electronic device. Correspondingly, as... Figure 1 As shown, the method includes:

[0036] S110. Obtain the secondary system associated data source of the target substation.

[0037] The target substation can be any substation that currently requires digital and visual management. The secondary system associated data source can be understood as a data source associated with the secondary system of the target substation, such as, but not limited to, secondary operation and maintenance data from SCADA (Supervisory Control And Data Acquisition) systems, real-time associated data from secondary systems, and non-real-time associated data from secondary systems.

[0038] In this embodiment of the invention, the secondary system digital visualization management platform can acquire the associated data sources of the secondary system of the target substation. Specifically, the secondary system digital visualization management platform can be a platform used for the digital and visual management of the substation's secondary system.

[0039] S120. Perform data cleaning and loading processing on the secondary system associated data sources to obtain electronic charts of the secondary system of the target substation, and build a secondary system knowledge base of the target substation based on the electronic charts of the secondary system.

[0040] Electronic diagrams of secondary systems can be diagrams that present information such as the topology, connection relationships, and equipment layout of a secondary system in electronic form. For example, they can be created and edited using electrical design software, drawing tools, or specialized secondary system management software. A secondary system knowledge base can be understood as a collection of information, data, and documents related to secondary systems. For example, a secondary system knowledge base can be used to record and manage various knowledge related to secondary systems, including but not limited to information on the design, configuration, operation, maintenance, and troubleshooting of secondary systems.

[0041] Specifically, the secondary system digital visualization management platform can filter and verify the secondary system related data sources of the target substation, thereby cleaning out the effective data. Then, the cleaned effective data is used to form electronic charts of the secondary system of the target substation according to the characteristics of the data itself, and the effective data is loaded into the secondary system knowledge base to build the secondary system knowledge base of the target substation based on the electronic charts of the secondary system.

[0042] S130. Obtain visualization data of the secondary system circuits of the target substation.

[0043] Among them, the secondary system loop visualization data can be understood as data that presents the circuit connections and signal flow of the secondary system in a graphical way.

[0044] Correspondingly, the secondary system digital visualization management platform can acquire visualization data of the secondary system circuits of the target substation, so as to more intuitively understand and analyze the structure and function of the secondary system.

[0045] S140. Update the secondary system knowledge base of the target substation based on the visualization data of the secondary system circuits.

[0046] Correspondingly, after obtaining the visualization data of the secondary system circuits of the target substation, the secondary system digital visualization management platform can update the secondary system knowledge base of the target substation based on the visualization data of the secondary system circuits.

[0047] For example, the secondary system loop diagram can be combined with the associated data of the secondary system knowledge base to expand and supplement the representation information of the secondary system loop diagram and provide an interactive query interface.

[0048] This invention, through obtaining the secondary system associated data source of the target substation, performs data cleaning and loading processing on the secondary system associated data source to obtain an electronic chart of the target substation's secondary system. Based on the electronic chart, a secondary system knowledge base of the target substation is constructed. By obtaining the visualization data of the secondary system circuits of the target substation, the secondary system knowledge base of the target substation is updated according to the visualization data of the secondary system circuits. This solves the problems of chaotic data management and non-visualization of secondary circuits in existing substations, and enables the digital processing and visualization management of substation secondary system data, improving the maintainability of substation secondary system data.

[0049] Example 2

[0050] Figure 2 This is a flowchart of a substation secondary system data processing method provided in Embodiment 2 of the present invention. This embodiment further optimizes and expands upon the above embodiment, providing various specific and selectable implementation methods for obtaining the associated data source of the target substation's secondary system, performing data cleaning and loading processing on the associated data source, constructing a secondary system knowledge base of the target substation based on electronic charts of the secondary system, and obtaining visualized circuit data of the target substation's secondary system. Correspondingly, as... Figure 2 As shown, the method in this embodiment may include:

[0051] S210. Automatically collect secondary operation and maintenance data and real-time related data of the SCADA system through periodic polling; among which, the real-time related data of the secondary system may include secondary operation and maintenance system ledger data and on-site operation record data, etc.

[0052] Secondary maintenance data can be data used for the maintenance and management of secondary systems. Real-time correlated data of secondary systems can be data that changes or updates in real time during the operation of the secondary system, such as, but not limited to, voltage, current, operation logs, and recorded data. Secondary maintenance system ledger data can be data from files or databases used to record and manage the maintenance activities and related information of the secondary system. On-site operation record data can be data used to record and manage on-site operation activities.

[0053] Correspondingly, the secondary system digital visualization management platform can automatically collect secondary operation and maintenance data of the SCADA system, as well as real-time related data of the secondary system, including secondary operation and maintenance system ledger data and on-site operation record data, through periodic polling.

[0054] S220. In response to a manually input data acquisition command, collect non-real-time correlated data of the secondary system; wherein, the non-real-time correlated data of the secondary system may include secondary system drawing data and secondary system configuration data, etc.

[0055] Among these, non-real-time correlated data for secondary systems can be data used to describe the characteristics of the secondary system itself and generally does not change. Secondary system drawing and documentation data can be data used to describe and record drawings and related documents of the secondary system. Secondary system configuration data can be data that records and describes the configuration information of various devices and components in the secondary system.

[0056] Correspondingly, the secondary system digital visualization management platform can respond to manual input data collection commands and collect non-real-time related data of the secondary system, such as secondary system drawings and configuration data.

[0057] S230. Perform data cleaning and loading processing on the secondary system-related data sources to obtain electronic charts of the secondary system of the target substation.

[0058] Optionally, data cleaning processing of secondary system-related data sources may include: filtering structured secondary system-related data sources; wherein the structured secondary system-related data sources include secondary maintenance system ledger data and SCADA system secondary maintenance data; determining structural reference information for unstructured secondary system-related data sources; wherein the structural reference information includes at least one of the following: protection equipment, action status, alarm content, and fault cause; and performing structural processing on unstructured secondary system-related data sources based on the structural reference information.

[0059] In this context, a structured secondary system association data source can be understood as data that has been arranged according to certain rules. An unstructured secondary system association data source can be understood as data that has not been arranged according to rules.

[0060] Correspondingly, after obtaining the aforementioned secondary system associated data sources, the secondary system digital visualization management platform can filter structured secondary system associated data sources such as secondary operation and maintenance system ledger data and SCADA system secondary operation and maintenance data. At the same time, it can determine structural reference information such as protection devices, action status, alarm content or fault causes for unstructured secondary system associated data sources, so as to perform structural processing on unstructured secondary system associated data sources based on the structural reference information.

[0061] Optionally, during the data cleaning process of the secondary system's associated data sources, the digital visualization management platform can focus on verifying incomplete data, abnormal erroneous data, and duplicate data records, and promptly perform manual processing or data supplementation.

[0062] Optionally, data loading processing of the secondary system associated data source may include: determining the characteristic attribute information of the cleaned secondary system associated data source; wherein the characteristic attribute information may include at least one of the following: secondary device ID (Identity Document), primary device ID, protection model, device parameters and setting sheet, commissioning report and cable information; and performing data loading processing on the cleaned secondary system associated data source based on the characteristic attribute information.

[0063] Secondary equipment can be understood as equipment in a power system used to monitor, control, and protect primary equipment, as well as to provide electrical energy to users. Primary equipment can be understood as the main equipment in a power system responsible for power transmission and distribution, used to transmit electrical energy and control the flow of power.

[0064] Correspondingly, during the data loading process of the secondary system associated data source, the secondary system digital visualization management platform can determine the characteristic attribute information of the cleaned secondary system associated data source, such as the secondary equipment ID, primary equipment ID, protection model, equipment parameters and setting sheet, commissioning report and cable information, so as to perform data loading processing on the cleaned secondary system associated data source based on the characteristic attribute information.

[0065] S240. Determine the secondary system associated objects of the target substation; wherein, the secondary system associated objects may include system devices and / or system circuits, etc.

[0066] S250. Establish an initial secondary system knowledge base for the target substation based on the secondary system associated objects of the target substation.

[0067] The secondary system's associated objects can be other devices, components, or entities that are directly related to and interact with the secondary system. The initial secondary system knowledge base can be an initial database or document containing basic information and specifications, used to record and manage the fundamental knowledge of the secondary system.

[0068] Accordingly, after obtaining the electronic diagrams of the secondary system of the target substation, the secondary system digital visualization management platform can identify the related objects of the secondary system, such as system devices and / or system circuits of the target substation, so as to establish an initial secondary system knowledge base of the target substation based on the related objects of the secondary system.

[0069] S260. Establish the connection relationship between the electronic charts of each secondary system based on the classification of main attributes and related attributes.

[0070] The primary attribute classification can include, but is not limited to, the characteristic attributes of equipment in the secondary system, such as equipment ID, equipment model, record number specifications, location, and connection method. The related attribute classification can be the related items between various electronic charts, such as, but not limited to, the connection relationship, wiring relationship, and signal transmission relationship between equipment, as well as the related items such as operation tasks, maintenance tasks, and inspection tasks related to the secondary system. For example, the secondary ledger of a certain line protection is linked to the corresponding primary ledger through the primary equipment ID.

[0071] Correspondingly, the secondary system digital visualization management platform can establish the connection relationship between the electronic charts of various secondary systems based on the classification of primary attributes and related attributes. For example, the data of various reports can be linked according to the classification of primary attributes and related attributes, and corresponding knowledge sub-bases can be established for objects of the secondary system, such as devices and circuits, thereby establishing a comprehensive secondary system knowledge base based on the relationships between objects.

[0072] S270. Update the initial secondary system knowledge base according to the connection relationship between the electronic charts of each secondary system.

[0073] Correspondingly, the secondary system digital visualization management platform can update the initial secondary system knowledge base based on the interconnected relationships between the electronic charts of each secondary system. For example, the data in the secondary system knowledge base can be updated through periodic polling during the secondary system's associated data source acquisition phase and manual commands. Alternatively, maintenance personnel can modify and update the data information of specified objects in the secondary system knowledge base via mobile terminals after discovering errors or omissions.

[0074] S280. Obtain visualization data of the secondary system circuits of the target substation.

[0075] Optionally, obtaining visualization data of the secondary system circuits of the target substation may include: parsing the SCD file of the target substation to obtain the configuration information of the target substation; drawing the associated module graphics of the IED (Intelligent Electronic Device) based on the configuration information of the target substation using the SVG (Scalable Vector Graphics) method; wherein the associated module graphics of the IED include at least one of the following: basic control block graphics, virtual port graphics, virtual terminal graphics, and virtual circuit graphics; establishing fiber optic links and electrical circuits between cabinets in the secondary system based on link circuit reference data; wherein the link circuit reference data includes secondary system drawing data, physical port data, and characteristic ID identifiers; mapping the virtual circuit graphics to the fiber optic links to obtain the visualization data of the secondary system circuits of the target substation.

[0076] Among them, the associated module diagram can be a diagram used to represent the relationship and interconnection between different modules in a secondary system.

[0077] Correspondingly, the process by which the secondary system digital visualization management platform obtains the visualization data of the secondary system circuits of the target substation can be achieved by parsing the SCD file of the target substation to obtain the configuration information of the target substation. Then, using the SVG method, it can draw the associated module graphics of IEDs, such as basic control block graphics, virtual port graphics, virtual terminal graphics, and virtual circuit graphics, based on the configuration information of the target substation. Subsequently, it can establish the fiber optic links and electrical circuits between cabinets in the secondary system based on the secondary system drawing data, physical port data, and characteristic ID identifiers and other link circuit reference data. The virtual circuit graphics are then mapped to the fiber optic links to obtain the visualization data of the secondary system circuits of the target substation.

[0078] S290. Update the secondary system knowledge base of the target substation based on the visualization data of the secondary system circuits.

[0079] Optionally, based on the above embodiments, it may further include: responding to an NFC (Near Field Communication) visitor authentication command, determining the target feature ID identifier requested by the NFC visitor authentication command; matching the secondary system knowledge base and the secondary system loop visualization data according to the target feature ID identifier to determine the target secondary system knowledge base and the target secondary system visualization loop; and feeding back and displaying the target secondary system knowledge base and the target secondary system visualization loop based on the visualization display interface.

[0080] The target feature ID can be an identifier used to identify and recognize target features. The target secondary system knowledge base can be a collection of information, data, and documents of the current secondary system that can be accessed by the NFC visitor authentication command request. The target secondary system visualization loop can graphically present the circuit connection relationships and signal flow of the current secondary system accessed by the NFC visitor authentication command request.

[0081] Correspondingly, the secondary system digital visualization management platform can respond to NFC visitor authentication instructions to determine the target feature ID identifier requested by the NFC visitor authentication instructions, and match the secondary system knowledge base and secondary system loop visualization data according to the target feature ID identifier to determine the target secondary system knowledge base and target secondary system visualization loop, so as to provide feedback and display the target secondary system knowledge base and target secondary system visualization loop based on the visualization display interface.

[0082] For example, in order to more clearly illustrate the technical solutions provided by the embodiments of the present invention, combining the above-mentioned optional technical solutions can yield an optional embodiment. Figure 3 This is a flowchart illustrating a data processing method for a substation secondary system applicable to Embodiment 2 of the present invention. In a specific example, such as... Figure 3 As shown, the data processing method for the secondary system of a substation, also known as the digital visualization method for the secondary system of a smart substation, can include the following six parts: digitization of basic secondary system data, visualization of secondary system circuits, NFC feature ID recognition, digital visualization mobile terminal, digital visualization application software, and visualization of secondary system data acquisition circuits.

[0083] in, Figure 4 This is a schematic diagram of a process for digitizing basic data of a secondary system applicable to Embodiment 2 of the present invention, as shown below. Figure 4 As shown, the secondary system digital visualization management platform can acquire secondary system-related data sources such as secondary operation and maintenance data, secondary operation and maintenance system ledger data, station operation record data, secondary system drawing and document data, and secondary system configuration data from the SCADA system of the smart substation. It then performs data cleaning on the acquired secondary system-related data sources to determine if the current data is normal. If the current data is normal, the cleaned normal data can be loaded into the secondary system knowledge base, thus completing the establishment of the secondary system knowledge base. The data in the knowledge base can be updated using periodic polling during the secondary system basic data acquisition phase and manual commands. Furthermore, maintenance personnel can use mobile terminals to modify and update information of specified objects after discovering errors or omissions. If the current data is not normal, the abnormal data needs to be manually processed, and the manually processed data is then cleaned again.

[0084] Figure 5 This is a flowchart of a secondary system loop visualization method applicable to Embodiment 2 of the present invention, as shown below. Figure 5 As shown, the steps for visualizing the secondary system loop can include the following four steps: Step 1: Parse the SCD file of the smart substation to obtain the substation's configuration information, such as IED configuration and communication parameters; Step 2: Draw the basic control blocks, virtual ports, and virtual terminals of different IEDs within the substation based on the configuration information and SVG technology; Step 3: Draw the link relationships (i.e., virtual loops) of virtual terminals in each IED based on the configuration information; Step 4: Based on the drawings and physical port information, establish fiber optic links and electrical loops between different cabinets by identifying them with feature IDs, and simultaneously map the virtual loops to the fiber optic links for virtual-physical correspondence.

[0085] After digitizing the basic data of the secondary system and visualizing the secondary system loops, the drawn secondary system loop diagram can be combined with the associated data of the secondary system knowledge base to expand and supplement the representation information of the secondary system loop diagram and provide an interactive query interface.

[0086] In this embodiment, the feature ID carrier of the secondary system can follow the substation secondary equipment identification specifications, using NFC technology to form feature IDs for different components of the secondary system. After NFC visitor authentication, it can conveniently access secondary system knowledge base data and secondary system circuit diagrams. Optionally, NFC visitor authentication can select substation operators and maintenance personnel; other personnel need a login password to pass authentication.

[0087] The digital visualization mobile terminal in this embodiment can be equipped with digital visualization application software, recognize NFC feature ID identifiers, and has both online and offline modes. For example, in online mode, the mobile terminal can communicate with on-site equipment in real time, obtaining the operating status and signals of secondary equipment both on-site and in the cloud. This, combined with the visualization application software, forms a real-time visualization of the secondary system. Simultaneously, after administrator authentication, the secondary system knowledge base and secondary system loops can be updated and modified online. In offline mode, after NFC feature ID authentication, the secondary system knowledge base data and loop diagrams of specified components can be obtained, providing storage functionality to store the data and loop diagrams that need updating. Updates can be loaded and loaded after a connection is established later. For example, the main body of the digital visualization mobile terminal can be a high-performance tablet computer equipped with a stylus, convenient for on-site personnel to use and clearly obtain chart information. The mobile terminal can be configured with a wireless communication module to achieve information interaction with on-site equipment, and can also be configured with 1TB (TeraByte) SSD (Solid State Disk) memory and a Type-C interface to connect to the on-site server to update data.

[0088] The digital visualization application software in this embodiment can identify the NFC feature ID of the secondary system and provide a visual display interface for the secondary system knowledge base data and secondary system circuits. It can be installed by maintenance personnel on NFC mobile devices such as mobile phones to obtain the basic data and secondary circuits of the corresponding components.

[0089] In this embodiment, the visualization interface can display different types of data from the knowledge base, such as alarm information tables and defect record tables, based on categories like substations, bays, and equipment IDs of the secondary system. For example, it can display the virtual and physical circuit topology diagrams between various components of the secondary system (such as virtual terminal circuits, electrical circuits, and the correspondence between virtual and physical circuits) based on bays and IEDs. Optionally, the visualization interface can provide a one-click wizard-style search interface. After entering keywords, the corresponding basic data and circuit topology of the secondary system can be displayed on the interface. The wizard-style search can retrieve data and information according to objects such as secondary circuits, cabinets, devices, cables, and signals.

[0090] Figure 6 This is a rendering of an electrical circuit visualization provided in Embodiment 2 of the present invention. Applying the above technical solution to a specific example, taking the 220kV Guanbaijia line as an example, the visualized secondary circuit electrical circuit can be displayed as follows: Figure 6 As shown, it can be found that through Figure 6 The visualization shown can improve the maintainability of substation secondary system data.

[0091] It should be noted that any arrangement or combination of the technical features in the above embodiments also falls within the protection scope of this invention.

[0092] The technical solution of this invention improves the digital and visual management capabilities of the substation and enhances the efficiency of intelligent operation and maintenance by cleaning and loading the secondary system associated data sources of the target substation based on the automatically collected and manually obtained secondary system associated data sources, constructing a secondary system knowledge base of the target substation based on the electronic charts of the secondary system, and obtaining visualized data of the secondary system circuits of the target substation.

Based on the electronic chart, a secondary system knowledge base of the target substation is constructed. By obtaining the visualization data of the secondary system circuits of the target substation, the secondary system knowledge base of the target substation is updated according to the visualization data of the secondary system circuits. This solves the problems of chaotic data management and non-visualization of secondary circuits in existing substations, and enables the digital processing and visualization management of substation secondary system data, improving the maintainability of substation secondary system data.
