[0043] Example 1

[0044] Embodiment 1 of the present invention proposes a method for intelligently mapping distribution network lines. This method effectively combines multiple data sources, including single-line diagrams, automation attributes, and terminal setting sheets, to heterogeneously generate four distribution network line diagram models: source diagrams, simplified diagrams, ring network diagrams, and setting diagrams. This method visualizes single-line structures, multi-line connections, and setting configurations, comprehensively addressing the diverse needs of scheduling and operation and maintenance.

[0045] like Figure 1 This is a flow chart of a method for intelligently mapping distribution network lines according to embodiment 1 of the present invention;

[0046] In step S100, the middle station single line diagram data is received, and based on the standard conversion rules, the middle station single line diagram data is converted into an automation diagram file, and the automation diagram file is parsed to form a single line source diagram.

[0047] The standard conversion rules in this invention are the format requirements for various power equipment descriptions in the "Power Grid GIS Platform and Distribution Automation System Application Integration Specification." Graphics and model files include graphic files and model files; graphic files use the SVG format; model files use the XML format.

[0048] The image file is compressed and encoded using base64, and then converted into E-text format through reverse isolation;

[0049] The Base64 formatted diagram file is decoded and parsed for incremental import, and the line diagram after the planned transformation is stored to form a single line source diagram.

[0050] In step S110, a tie switch is identified from the single-line source diagram, and the type of interconnected lines to the substation bus is identified through the tie switch to form a single-line diagram or a multi-line ring network diagram;

[0051] This step includes 110A and 110B, and 110A and 110B are performed simultaneously.

[0052] The method for identifying a tie switch from a single-line source diagram includes: extracting a database brk_connect_type attribute from the single-line source diagram, and determining whether the tie switch is a tie switch according to the brk_connect_type attribute.

[0053] Step 110A is as follows: the tie switch identifies the trunk line equipment to the 10kV busbar of a single substation according to the single-side topology, forms a simplified equipment list, and forms a single line diagram point by point according to the simplified equipment list;

[0054] Step 110B is: the tie switch identifies the interconnected lines to the 10kV busbars of the two substations according to the double-side topology, forms a ring network equipment list, and forms a multi-line ring network diagram point by point according to the network equipment list.

[0055] In step S120, the distribution terminal operation setting is called and tested, and the setting is combined with the single line diagram to form a single line setting diagram of the distribution network.

[0059] Analyze the set value data and combine it with the single line diagram to form a single line set value diagram of the distribution network.

[0060] A method for intelligently mapping distribution network lines proposed in Example 1 of the present invention distinguishes and forms four different graphics: source diagram, simple diagram, ring network diagram, and set value diagram. Different graphics are extracted for different users and different scenarios, realizing visualization of power supply paths, visualization of protection set values, and visualization of power outage ranges, greatly improving the efficiency of distribution network terminal operation and maintenance and accident handling.

[0061] A method for intelligent mapping of distribution network lines proposed in Example 1 of the present invention can extract and parse the middle-end diagram file, automatically form a single-line source diagram, avoid repeated maintenance of different systems, realize "source-end maintenance, global sharing", and greatly improve work efficiency.

[0062] In a method for intelligently mapping distribution network lines proposed in Example 1 of the present invention, model data is derived from a middle-office system. In the early stages, a three-party review by the equipment owner, professional management, and operating mode has been completed to ensure that the model data is consistent with the actual on-site diagram. After a line fault occurs, it can be accurately located, isolated, and power supply restored, greatly improving social benefits.

[0063] Example 2

[0064] Based on the method for intelligently mapping a distribution network line proposed in Example 1 of the present invention, Example 2 of the present invention proposes an apparatus for intelligently mapping a distribution network line, such as Figure 2 This is a connection diagram of a device for intelligently mapping distribution network lines according to embodiment 2 of the present invention. The device includes a middle platform, a management information area, and a production control area.

[0065] The middle station is used to receive the middle station single line diagram data;

[0066] The management service area is connected to the middle office for communication, which is used to transmit the middle office single line diagram data to the production control area in E-text format through the physical isolation device;

[0067] The production control area is used to parse out the single-line source diagram, and form a single-line simplified diagram or a multi-line ring network diagram through the single-line source diagram; as well as to call and test the distribution terminal operation set values, so that the set values ​​are combined with the single-line simplified diagram to form a single-line set value diagram of the distribution network.

[0068] In the present invention, the middle platform single line diagram is converted into an automated graphic model file according to standard conversion rules, the graphic file adopts the SVG format, and the model file adopts the XML format.

[0069] The WebService interface is used to transfer the Base64-encoded image template file from the middle platform to the management information area.

[0070] A first forward physical isolation device and a first reverse physical isolation device are set between the management information area and the production control area. The management information area is transmitted to the production control area in E text format through the first reverse physical isolation device.

[0071] After decoding in the production control area, the incremental analysis is imported and stored in the red map. After completing the red and black map process, a single-line source map is formed.

[0072] When adding or modifying equipment on a line, the red diagram represents the planned line diagram after modification, and the black diagram represents the current line diagram before modification. When the equipment is added or modified, the red diagram turns black, and the new black diagram represents the completed line diagram.

[0073] The reverse isolation device is a piece of hardware designed to facilitate secure, non-network data exchange between different security zones (such as the production control zone, management information zone, and secure access zone) to prevent hacker attacks. It operates in a similar manner to the forward and reverse isolation devices in the production service zone. For example, when zone A transmits data to zone B via forward isolation, the forward isolation device first connects to zone A to receive data, then disconnects from zone A before connecting to zone B to transmit the data. When zone B transmits data to zone A via reverse isolation, the reverse isolation device performs signature verification, content filtering, and validity checks on the data.

[0074] The digital mapping micro-application in the production control area extracts the brk_connect_type attribute from the database and automatically determines whether it is a tie switch. The tie switch identifies the main line equipment to the 10kV busbar of a single substation according to the single-side topology, forming a simplified equipment list, and then forming a single-line simplified diagram point by point according to the list.

[0075] In the model file, the tie switch has ledger attributes for the feeder it belongs to, while in the graphic file, each device has attributes for the node numbers on both sides. Take the node numbers A1 and A2 on both sides of tie switch A, and search the database for the next topological device B that matches the node number on one side (A1 or A2) and belongs to the same feeder line. Assuming that one of B's ​​node numbers B1 equals A2, take the node number B2 on the other side of B, and search the database for the next topological device C that matches B2's node number and belongs to the same feeder line. And so on, ending with the substation busbar node number. Similar to dominoes, tracing back to one side.

[0076] The database brk_connect_type attribute is extracted to automatically determine whether it is a tie switch. The tie switch identifies the interconnected lines to the 10kV busbars of the two substations according to the bilateral topology, forming a ring network equipment list. According to the list, a multi-line ring network diagram is formed point by point.

[0077] In the model file, the tie switch has ledger attributes for the feeder it belongs to, and in the graphic file, each device has attributes for the node numbers on both sides. Take the node numbers A1 and A2 on both sides of tie switch A, and search the database for the next topological device that matches the node number on one side (A1 or A2). For example, if device B's node number B1 matches A's node number A1, and device C's node number C1 matches A's node number A2, then take the node numbers B2 and C2 on the other side of devices B and C, and search the database for topological devices that match B2 and C2, and continue until the two substation busbar node numbers are reached. Similar to dominoes, tracing back to the source on both sides.

[0078] Create a terminal constant value model, aligning the constant value coding format and names with those of on-site terminals. Intelligent distribution terminals connect to the secure access zone via a wired private network or wireless public network, utilizing standard IEC101 or IEC104 communication protocols for terminal operational constant value call testing. The "Detailed Implementation Rules for the Application of Distribution Automation Systems (DLT634.5101-2002)" and "Detailed Implementation Rules for the Application of Distribution Automation Systems (DLT634.5104-2002)" specifications outline requirements for the interactive process of remote parameter access. These include reading from the constant value area, reading the constant value, issuing the constant value, and confirming the constant value.

[0079] The security access area is connected to the production control area through a second reverse physical isolation device, and transmits the terminal constant data in the e-file format to the production control area.

[0080] The production control area analyzes the running set values ​​and automatically writes them into the corresponding labels of the set value diagram. A unified interactive text specification is established to agree on the transmission content and perform data analysis according to the agreed format.

[0081] The terminal data acquisition module in the production control area is connected to the intelligent power distribution terminal.

[0082] Digital mapping micro-applications are deployed in the production control area of ​​the distribution automation system. These include: red and black map import module, terminal fixed value call module, and one-click mapping module.

[0083] The red and black diagram import module is deployed on SCADA to receive the automation diagram file from the middle platform, parse the incremental data, write it into the SCADA database of the production control area server, and generate a single line source diagram;

[0084] The terminal fixed value call test module is deployed on SCADA and is used to call and test the operating fixed values ​​of the on-site power distribution terminals and write them into the single-line fixed value diagram label;

[0085] One-key drawing module, deployed on SCADA, is used to compile drawing rules and generate single-line diagrams, multi-line ring network diagrams, and single-line fixed values ​​as required. Figure 3 Class graphics.

[0086] The one-key drawing module has graphic editing and network saving functions; an editing toolbar is configured in the graphic editing, and through buttons such as alignment, move, flip, drag, and mark, it has the function of manually adjusting graphics with unreasonable layouts; the network saving function realizes stand-alone operation and full network sharing of graphics through real-time file synchronization services; the production control area of ​​the distribution automation master station system is connected to the interface server of the information management area through a forward physical isolation device, and realizes graphic synchronization of the information management area in a cross-region service bus manner.

[0087] To quickly open the four types of graphics, you can create a link directory page in the human-computer interaction interface and create quick links in the form of icons or characters.

[0088] Embodiment 2 of the present invention proposes a device for intelligently mapping distribution network lines, which distinguishes and forms four different types of graphics: source diagram, simple diagram, ring network diagram, and constant value diagram. Different graphics are extracted for different users and different scenarios to achieve visualization of power supply paths, visualization of protection constant values, and visualization of power outage ranges, greatly improving the efficiency of distribution network terminal operation and maintenance and accident handling.
