Description

Technical Field

[0001] This invention relates to the field of intelligent substations, and more specifically, to a method, apparatus, computer equipment, and storage medium for automatically generating virtual terminal configuration tables for intelligent substations. Background Technology

[0002] A smart substation refers to a substation that uses advanced, reliable, integrated, low-carbon, and environmentally friendly intelligent equipment. It is based on the basic requirements of full-station information digitization, communication platform networking, and information sharing standardization. It automatically completes basic functions such as information collection, measurement, control, protection, metering, and monitoring, and can support advanced functions such as real-time automatic control, intelligent regulation, online analysis and decision-making, and collaborative interaction of the power grid as needed.

[0003] Smart substations use optical fibers instead of the secondary cables found in conventional substations. Secondary cables are clearly visible, with each cable transmitting analog or digital signals. Optical fibers, on the other hand, are a set of fibers that can transmit multiple sets of analog or digital signals. Smart substations use the concept of "virtual terminals" to express the data transmission relationships within the optical fiber, equivalent to the secondary cable connections in a conventional substation (that is, the internal connections of the optical fiber are determined by virtual terminals).

[0004] For electrical design institutes, upgrading and transforming smart substations is an inevitable trend. However, given the sheer number of substations and the limited number of electrical design and drafting personnel, replacing cables with fiber optics requires redrawing drawings to clarify the connections between electrical equipment. Many electrical design drawings are improvements on existing cable design drawings, requiring designers to revise them again into new drawings, much of which involves repetitive work.

[0016] As a further optional solution to the method for automatically generating the virtual terminal configuration table of the intelligent substation, if the database also includes terminal block information from multiple manufacturers, then the method further includes: calling the drafting software, matching the first virtual terminal information with the terminal block information in the database in the drafting software, and generating a terminal block table.

[0017] As a further optional solution to the method for automatically generating the virtual terminal configuration table of the intelligent substation, the method further includes:

[0018] After detecting that the user has selected a target terminal block in the terminal block table, the drawing software is controlled to call the terminal block information in the database and perform data processing to generate a virtual terminal block configuration table.

Parameter information from both old and new intelligent substations is recorded in the database. Parameters from old substations are stored as first original parameters, including the connection relationships between power generation equipment and old monitoring equipment. Parameters from new substations are stored as new parameters, including the connection relationships between power generation equipment and new monitoring equipment. The power generation equipment is identical, while the new and old monitoring equipment partially overlap and partially differ. The original drawings are analyzed to obtain second original parameters, which are then inserted into the database using drafting software. The database matches the second original parameters with the new parameters to obtain second virtual terminal information that is compatible with the new parameters. The second virtual terminal is a parameter in the new drawings and is included in the first virtual terminal information. Therefore, the new parameters and the second virtual terminal information are integrated to form a new drawing. The automatic generation method of the virtual terminal configuration table for intelligent substations in this invention can batch process the conversion of original drawings into new drawings, thereby greatly improving drafting efficiency and avoiding a large amount of repetitive work for designers.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0041] This invention provides a method for automatically generating a virtual terminal configuration table for intelligent substations. Please refer to [link / reference]. Figures 1-4 The automatic generation method for the virtual terminal configuration table of this intelligent substation includes:

[0042] Step S100: Classify and organize all parameter information required in the substation design process into a database. The database includes first original parameters, new parameters, and virtual terminal information. The first original parameters include the connection relationship between power generation equipment and old monitoring equipment in the old substation. The new parameters include the first virtual terminal information between power generation equipment and new monitoring equipment in the new substation. The virtual terminal information is used to indicate the connection relationship during display. Power generation equipment, connection relationship, and virtual terminal information have a corresponding relationship.

[0043] Step S200: Extract the second original parameter from the information in at least one original drawing of the old substation through image recognition. The second original parameter belongs to all or part of the first original parameter.

[0044] Step S300: Call the mapping software and insert the database and the parsed second original parameters into the mapping software;

[0045] Step S400: Call the drafting software, use the second original parameters and correspondence in the database to match the new parameters and obtain the second virtual terminal information that is used in conjunction with the new parameters, and generate a new drawing of the new substation based on the new parameters and the second virtual terminal information.

[0046] Based on the automatic generation method of the intelligent substation virtual terminal configuration table in the above embodiments, a database is first established, and all parameter information related to the substation design process is uniformly entered into the database. Parameter information from both old and new intelligent substations is recorded in the database. Parameters from the old substation are stored as first original parameters, including the connection relationships between power generation equipment and old monitoring equipment. Parameters from the new substation are stored as new parameters, including the connection relationships between power generation equipment and new monitoring equipment. The power generation equipment is all the same; the new and old monitoring equipment partially overlap and partially differ. The original drawings are parsed to obtain second original parameters, which are then inserted into the database using drafting software. The second original parameters and new parameters are matched in the data to obtain second virtual terminal information used in conjunction with the new parameters. The second virtual terminal is a parameter in the new drawings and is included in the first virtual terminal information. Therefore, some original and new parameters, the new parameters, and the second virtual terminal information are integrated into a new drawing. The automatic generation method for virtual terminal configuration tables of intelligent substations in this invention can batch process original drawings and convert them into new drawings, thereby greatly improving drafting efficiency and avoiding a lot of repetitive work for designers.

[0047] In some specific embodiments, the database includes cable model information and equipment information; the second virtual terminal information includes second core wire model information and core wire connection relationships. ；

[0048] The process of generating new drawings for the new substation based on the new parameters and the second virtual terminal information includes:

[0049] The cable model information and equipment information of the power generation equipment in the new substation are integrated with the information of the new monitoring equipment, the second core wire, and the core wire connection relationship to generate new drawings.

[0050] "Core wire" refers to the type of optical cable. Each type of optical cable contains multiple optical cores, and each optical core contains multiple optical fibers. Therefore, there are many types and models of core wires, and different core wires correspond to different equipment.

[0051] A cable is a device for transmitting electrical energy or signals, typically composed of several or groups of conductors. Therefore, there are various types of cables available.

[0052] A virtual end port (VEPort), or simply VE port, is a logical port divided from a physical port, implemented using virtualization technology. VE ports can be added, deleted, and modified at any time, facilitating network device management and resource sharing. The corresponding network device here is a secondary device.

[0053] The functions of virtual terminals include: 1. Improving network utilization: Virtual terminals can divide a single port into multiple logical ports, thereby enabling network resource sharing and improving network utilization; 2. Reducing network costs: Virtual terminals can divide a single physical port into multiple logical ports, reducing the use of physical ports and thus lowering network costs; 3. Facilitating management: Virtual terminals can be added, deleted, and modified at any time, facilitating the management of network devices.

[0054] Equipment typically refers to secondary electrical equipment. In the field of electrical equipment:

[0055] 1. Power generation equipment generally refers to primary equipment, which is high-voltage electrical equipment that directly produces, transmits, and distributes electrical energy. It includes generators, transformers, circuit breakers, disconnectors, automatic switches, contactors, knife switches, busbars, transmission lines, power cables, reactors, motors, etc. The electrical circuit formed by the interconnection of primary equipment for power generation, transmission, distribution, or other production processes is called a primary circuit or primary wiring system.

[0056] 2. Monitoring equipment typically refers to secondary equipment. Secondary equipment consists of low-voltage electrical devices used to monitor, control, regulate, and protect primary equipment, as well as to provide operating conditions or production command signals to operation and maintenance personnel. Examples include fuses, control switches, relays, and control cables. The electrical circuit formed by the interconnection of secondary equipment to monitor, control, regulate, and protect primary equipment is called a secondary circuit or secondary wiring system.

[0057] In this embodiment, the substations are already built. The typical upgrade involves transforming them into smart substations compliant with the IEC 61850 standard. This mainly involves updating some electrical equipment and replacing cables with fiber optic cables to connect the various electrical devices. Substation upgrades must be carried out according to the design drawings provided by the design institute. Since the existing electrical equipment remains largely unchanged, modifications are generally made to the previous electrical drawings. Redesigning the substations could conflict with the existing site layout, resulting in a massive workload for on-site modifications and potentially disrupting the power grid's operation.

[0058] Currently, my country has over 48,000 substations. These substations need to be upgraded to smart substations in batches, which first requires electrical design institutes to produce upgrade drawings. Modifying so many drawings one by one is difficult to complete in a short time. However, the automatic generation method for intelligent substation virtual terminal configuration tables in this embodiment can generate new drawings, namely electrical / optical / tail cable tables, in a short time. Designers only need to spend some time verifying and fine-tuning; newly installed electrical equipment can be added using virtual terminals, and old electrical equipment can be deleted, etc. This greatly improves the speed at which design institutes can produce intelligent substation design drawings.

[0059] In this embodiment, cable model information, core wire information, dummy terminal information, and equipment information are generally categorized and listed in a table, and corresponding relationships are established among these information. The main difference between the original and new drawings is that core wire connections replace cable connections, and some intelligent secondary devices are used in conjunction with them. The connection relationships of the primary devices remain unchanged and are unlikely to be replaced.

[0060] In some specific embodiments, the cable model information and equipment information of the power generation equipment in the new substation are integrated with the new monitoring equipment, the second core wire information and the core wire connection relationship to generate a new drawing. This includes: pre-setting the cable model information and equipment information of the power generation equipment in the new substation with the new monitoring equipment, the second core wire information and the core wire connection relationship into different blocks, and using the obtained blocks to form a new drawing.

[0061] A block is a graphic representation where designers pre-define all equipment, cables, wire data, and connection relationships as symbols, achieving standardization and ensuring that designers, construction personnel, and acceptance personnel can accurately understand its meaning. Generally, it follows the IEC 61850 standard, but sometimes it may also adhere to internal company standards.

[0062] In some specific embodiments, the database also includes terminal block information from multiple manufacturers. The method further includes: calling a drafting software, matching the second virtual terminal information with the terminal block information in the database in the drafting software, and generating a terminal block table.

[0063] Because electrical equipment is a very important field, all electrical equipment procurement can be traced back to its source. There is usually a supplier database containing information such as the models of products that suppliers can supply. By using core wire information, equipment information, and virtual terminal information, a manufacturer's terminal block can be generated, directly producing the type and quantity of terminal blocks that need to be procured.

[0064] Typically, the same terminal block will be generated from multiple supplier lists, or multiple terminal blocks will be generated to meet the on-site construction requirements of the drawings. For example, there may be more than two types of terminal blocks that can meet the design requirements in the electrical / optical / tail cable drawings. In this case, all terminal blocks should be generated to facilitate centralized procurement.

[0065] In the database, first match the terminal block corresponding to the first virtual terminal information, and then find the terminal block corresponding to the second virtual terminal from the first virtual terminal.

[0066] In this embodiment, terminal blocks are associated one-to-one with core wires and dummy terminals. Here, one type of dummy terminal may correspond to multiple different types of core wires, and one type of core wire may correspond to multiple different types of terminal blocks.

[0067] In some specific embodiments, the method further includes: after detecting that the user has selected a target terminal block in the terminal block table, controlling the drawing software to call the terminal block information in the database and perform data processing to generate a virtual terminal block configuration table, wherein the virtual terminal block configuration table includes information receiving attributes and path attributes: the information receiving attributes include SV receiving and GOOSE receiving; the path attributes include the destination device, the destination virtual terminal block data attributes, the destination device virtual terminal block description, the starting device, the starting device virtual terminal block data attributes, and the starting device virtual terminal block description.

[0068] Virtual terminal connections are mainly divided into two categories: SV and GOOSE. SV is associated with the DO layer, and GOOSE is associated with the DA layer.

[0069] The IEC 61850 standard is a globally recognized standard in the field of power system automation. The IEC 61850 standard specifies that virtual terminal connections are mainly divided into two categories: SV and GOOSE.

[0070] In substations, SV stands for Sampled Value. SV information includes the current and voltage values ​​on the secondary side of the instrument transformer. The SV link is equivalent to the secondary AC cable in a traditional substation. It is electrical quantity information that is integrated and packaged by a merging unit and then transmitted to intelligent devices via a transmission medium or switch. SV messages are transmitted between the process layer and the bay layer.

[0071] GOOSE stands for General Object-Oriented Substation Event. It uses a publisher / subscriber approach to enable rapid one-to-many data transmission between devices. In relay protection systems, GOOSE messages typically serve as carriers of trip / close signals, switch position information, interlocking signals, and alarm indicator information, transmitted between protection units and intelligent terminals, as well as within GOOSE messages themselves. GOOSE information is transmitted at the process level, bay level, and within the bay level itself.

[0072] Path attributes are provided to facilitate acceptance testing, as the connections between devices cannot be visually observed through virtual terminal connections. Therefore, a virtual terminal configuration table can be provided, allowing verification of the correctness of the connections between each device. Furthermore, all attribute information in the virtual terminal configuration table informs acceptance personnel about the data signal transmission path. Of course, path attributes also guide the actual construction personnel on how to set relevant parameters.

[0073] The selection of specific terminal blocks in this terminal block list mainly involves the procurement process, where the specific terminal blocks are determined through interaction between construction personnel, procurement personnel, and manufacturers. Designers are only responsible for defining the selection or scope of terminal blocks.

[0074] In some specific embodiments, the file format of the path attribute in the database is an SCD file or an ICD file. The method further includes: when the file format of the path attribute is an SCD file, controlling the drawing software to call the SCD file, reading the information in the SCD file and generating a virtual terminal configuration table.

[0075] When the file format of the path attribute is an ICD file, the data processing first creates the substation bay, the control drawing software calls the ICD file and allocates the data in the ICD file to different substation bays, and the control drawing software calls the substation bays to generate a virtual terminal configuration table.

[0076] The ICD file is the IED capability description file. Provided by the device manufacturer to the system integrator, this file describes the basic data model and services provided by the IED, but does not include the IED instance name and communication parameters. The SCD is the station-wide system configuration file, which should be unique across the entire station. This file describes the instance configuration and communication parameters of all IEDs, the communication configuration between IEDs, and the substation primary system structure, and is completed by the system integrator based on the ICD. The CID is the IED instance configuration file; each device has one, generated by the device manufacturer based on the relevant configuration of that IED in the SCD file.

[0077] Technology is constantly evolving, and the market is constantly changing, so the data in the power grid database also needs to be updated in real time. The terminal blocks provided by manufacturers are also constantly developing and updating; if a manufacturer updates the terminal blocks, they need to provide corresponding documentation. Some manufacturers provide ICD files, while others provide SCD files. Therefore, it is necessary to first identify the file type before further processing can be performed to extract the information.

[0078] SCD files guarantee the uniqueness of virtual terminal connections, so they can be imported directly.

[0079] It should be noted that manufacturers provide terminal blocks and core wires, while the virtual terminal configuration table and virtual terminal table are essentially the instruction manuals for these terminal blocks and core wires. Therefore, the data attributes of the endpoint virtual terminal, the description of the endpoint device virtual terminal, the data attributes of the starting point virtual terminal, and the data of the starting point device virtual terminal can generally be automatically imported and identified from the manufacturer's SCD file.

[0080] A substation bay refers to a complete, independently operating assembly of electrical equipment within a substation. A substation bay can be viewed as a basic unit within the substation's electrical system, composed of various devices including circuit breakers, disconnectors, grounding switches, instrumentation equipment, and protection devices.

[0081] The main function of a substation bay is to bring electrical energy from the power system to the substation and then send it to where it is needed. It is an important part of the normal operation of a substation. Each substation contains multiple sets of substation bays, each of which is independent of each other and has its own protection and control devices and circuit breakers, etc., to achieve segmented control and protection of the substation.

[0082] In the IEC 61850 standard for intelligent substations, the IED Capability Description is a document provided by the device manufacturer to the system integrator. It describes the basic data model and services provided by the IED (Intelligent Electronic Device), but does not include the IED instance name or communication parameters. The IEC 61850 standard divides the substation communication system into three layers: station control layer, bay layer, and process layer.

[0083] In this embodiment, the general data processing flow is to first identify whether the manufacturer's file format is an SCD file or an ICD file, and then perform corresponding processing according to the specific file format.

[0084] In some specific embodiments, the drafting software is CAD software.

[0085] The drafting software can be CAD design software. CAD design software is a commonly used design software, especially AutoCAD, which is frequently used by designers and has comprehensive basic functions. In the example, all tables, such as the equipment table, virtual terminal configuration table, and cable model table, are generally Excel spreadsheets. Due to the large amount of data, it is usually input and output in tabular form. Excel spreadsheets can be recognized by CAD files, and CAD files can also be exported as Excel spreadsheets. Furthermore, Excel spreadsheets are convenient for updating and maintaining data.

[0086] Typically, these Excel spreadsheets are bound to CAD files, and corresponding feedback is provided as the data in these Excel spreadsheets is modified.

[0087] Furthermore, in CAD software, defining a block involves grouping one or more objects into a unit and giving it a unique name, allowing it to be inserted, copied, and moved as a whole. In the field of electrical equipment design, CAD software typically loads pre-edited blocks, and these blocks follow standardized naming rules to facilitate designers' use and insertion within the CAD software.

[0088] The above steps require selecting the drawing to be identified, choosing the core wire specifications and terminal block information; everything else is automatically generated by the computer equipment.

[0089] Secondly, the present invention provides an electrical equipment secondary design import device, the device comprising:

[0090] The sorting module is used to classify and organize all the parameter information required in the substation design process into a database.

[0091] The parsing module is used to extract the second set of original parameters of the old substation from the information in the original drawings of the substation through image recognition.

[0092] The insertion module is used to call the drafting software and insert the database and the parsed second original parameters into the drafting software;

[0093] The matching and generation module is used to call the drafting software, match the second original parameter and the new parameter in the database in the drafting software, obtain the second virtual terminal information that is used in conjunction with the new parameter, and generate a new drawing of the new substation based on the new parameter and the second virtual terminal information.

[0094] Thirdly, please refer to Figure 2 The present invention provides a computer device including a processor and a memory; the processor is configured to execute a computer program stored in the memory to implement the method as described in any of the first aspects.

[0095] Fourthly, the present invention provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements any of the methods of any of the first aspects.

[0096] The present invention discloses an automatic generation method, device, computer equipment, and storage medium for virtual terminal configuration tables in intelligent substations. This method and device are integrated into a series of processes during the intelligent transformation of substations, from new drawing design and operation guidance by construction personnel to verification by acceptance personnel, thereby greatly improving the efficiency of the intelligent transformation process of substations.

[0097] Among them, the new drawings correspond to the designers, the terminal block table and the virtual terminal configuration table correspond to the construction personnel, and the new drawings, terminal block table and virtual terminal configuration table correspond to the acceptance personnel.

[0098] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0099] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
