Description

Technical Field

[0001] The present invention relates to the technical field of management systems, and in particular, to an intelligent management system for secondary circuit labels in a substation. Background Art

[0002] With the rapid development of intelligent substations, the complexity of secondary systems has increased significantly, and the traditional management of secondary circuit identification faces severe challenges. The existing technologies mainly have the following problems:

[0003] 1. Disconnection of virtual and physical circuit information In an intelligent substation, virtual circuits achieve logical connections through the definition of virtual terminals in the SCD file, while physical circuits achieve hardware connections through physical optical cables and ports. In the existing technologies, design drawings only show the physical connection paths, and the SCD file only describes virtual terminal signals, lacking an effective association mechanism between the two. Maintenance personnel need to consult the drawings and the SCD file simultaneously for manual comparison, and it is difficult to quickly locate the physical transmission path corresponding to the virtual terminal signal. For example, when a GOOSE signal transmission anomaly occurs, it is impossible to directly determine the switch port or fiber distribution frame node through which the signal passes based on the optical cable label, resulting in low fault troubleshooting efficiency.

[0004] 2. Incomplete traditional identification information Conventional substations use a two-level signage (optical cable signage + optical fiber core number plate) identification method, and the label content only includes physical connection information (such as starting / ending equipment, port number), lacking the description of key virtual terminal signals. In an intelligent substation, a single optical fiber may carry multiple SV sampling values or GOOSE control signals, and the existing labels cannot reflect the specific transmitted signal content, control block attributes, and signal flow direction. For example, a certain optical fiber label only indicates "1-A→2-B", but it cannot explain whether the optical fiber transmits a protection trip signal or measurement data, resulting in a risk of misoperation in on-site maintenance.

[0005] 3. High manual dependence and error-prone In the existing technologies, the matching of virtual and physical circuits depends on manual comparison of the SCD file and design drawings. For a 220 kV substation, the virtual circuit table can reach tens of thousands of records, and manual verification is prone to problems such as missed inspections and incorrect matching. Especially in renovation and expansion projects, physical port changes and virtual terminal modifications are often not synchronized, resulting in the classic problem of "discrepancy between drawings and the site". According to statistics, approximately 35% of secondary system faults are due to inconsistent virtual and physical circuit configurations, and traditional methods lack an automated virtual-physical consistency verification mechanism.

[0006] 4. Static label information Existing QR code labels mostly use fixed coding rules (such as device code + port number), which cannot dynamically associate with real-time updated SCD configuration information. When the virtual circuit changes, all related labels need to be reprinted and replaced, resulting in increased operation and maintenance costs. In addition, conventional label parsing can only display static device information, and cannot link to display the virtual terminal signal path, signal type (such as GOOSE / SV) and associated protection logic, which makes it difficult to meet the dynamic operation and maintenance needs of smart substations.

[0007] 5. Insufficient standardization. Although Q / GDW 1396-2012 standardizes the description method of virtual terminals, the mapping relationship between physical ports and virtual terminals lacks a unified modeling standard. Different manufacturers have different interpretations of the "PhysConn" element, resulting in the same physical port in the SCD file being marked as "1-A" (board-port) or "Slot1 / PortA" (slot / port), making cross-system data integration difficult. This heterogeneity makes it difficult for existing tag management systems to achieve unified modeling and data integration of multi-vendor devices.

[0008] Therefore, a substation secondary circuit tag intelligent management system is proposed to solve the above problems. Summary of the invention

[0062] A physical modeling unit, which is used to construct a physical connection model including the levels of cubicles, switchboards, devices, boards, and ports;

[0063] The virtual-real matching engine couples the virtual loop configuration table and the information logic path table through a port mapping algorithm.

[0064] The virtual-real matching engine performs the following steps:

[0065] S1. Screen the records with the same control block name, virtual terminal type, sending / receiving device, and port from the virtual loop configuration table to generate a virtual loop cache pool;

[0067] S3. Verify the existence of the sending device port in the sending port list of the virtual loop cache pool and mark the matching status;

[0068] S4. Generate a virtual-real loop difference report and a visual topology diagram.

[0069] The intelligent label generation module includes:

[0070] A label template library that pre-sets the format templates for optical cable labels, optical fiber labels, and patch panel labels;

[0071] A dynamic coding unit that generates a two-dimensional code containing device hierarchy information and virtual terminal attributes using a hierarchical structure;

[0072] A batch printing interface that supports outputting label files to a printing device by screen cabinet classification.

[0073] The coding rule of the two-dimensional code is as follows:

[0074] The hanging label two-dimensional code includes the power grid area code, substation identifier, cable number, and screen cabinet number;

[0075] The P-type flag label two-dimensional code includes the device number, board position, port number, and signal flow direction Tx / Rx;

[0079] A data association unit that retrieves the physical path diagram or virtual terminal configuration diagram according to the two-dimensional code type;

[0080] A virtual-real linkage interface that synchronously highlights the optical fiber physical path and the virtual terminal signal list carried by it.

[0081] This embodiment further includes:

[0082] The consistency check module verifies the port mapping consistency of the virtual and physical circuits through a traversal algorithm;

[0083] The collaborative correction interface provides a data synchronization channel between the SCD configuration tool and the information logic diagram configuration tool.

[0084] The multi-source database module includes:

[0085] The physical model library stores the device hierarchical relationship and the port connection path;

[0086] The virtual circuit library records the control block name, signal type, and send / receive port attributes;

[0087] The label rule library saves the QR code encoding rules, printing template parameters, and version history.

[0088] Exemplarily, in a smart substation, the virtual circuit information is expressed by connecting virtual terminals in the SCD file. In the "Q / GDW1396-2012 IEC 61850 Engineering Relay Protection Application Model", it is stipulated that the physical ports of the GOOSE and sampled SV receiving access points are associated. That is, the physical port description is added to the "intAddr" attribute of the "ExtRef" element. The physical port is expressed in the x-y format, where x represents the board card number and y represents the port number. For example, intAddr = "1-A:PIGO / GOINGGIO1.DPCSO1.st Val" indicates that the receiving port of this virtual terminal is port A of board card 1. By introducing the physical port in the Inputs of the SCD file, the receiving port of the storage device is stored. At the same time, the specification also stipulates the method for describing multiple physical sending ports of the device access point. Under the "Connected AP" element, the "Connection" and "Red Conn" attributes of the "PhysConn" element are used. When the attribute value is "Connection", the first physical network port is defined. When the attribute value is "Red Conn", other redundant physical connection network ports are defined. All allowed sending port information is stored for each access point. For example:

[0089] <Phys Conn type="Connection">

[0090] <p type＝"port">1-A

[0091] <Phys Conn type="Red Conn">

[0092] <p type＝"port">1-B

[0093] <Phys Conn type="Red Conn">

[0094] <p type＝"port">1-C

[0095] < / Phys Conn> indicates that the ports allowed to be sent by this access point are the A, B, and C ports of the first board. In this way, the sending ports are not unique, so the one-to-one correspondence relationship between the ports of devices cannot be achieved only through the SCD file.

[0096] In the implementation process, first use the SCD configuration tool to configure the SCD file, and parse and store the virtual loop information in the SCD file in the database. According to the control block to which the sending virtual terminal belongs in the "Ext Ref" element of the receiving device, obtain the sending device name and the list information of all sending port names under the corresponding "Connected AP" element, and obtain the receiving port information according to the "int Addr" attribute, and store it in the virtual loop table.

[0097] When designing a substation project, it is necessary to design the information logic diagram of the secondary system in the station, showing the device names, connection relationships, information flow directions, information contents, etc. of the devices with information interaction relationships (including current, voltage, tripping, signals, etc.), so as to express the actual loop connection relationship between the ports of IED devices (sending devices and receiving devices). First, configure the site information of the secondary equipment in the station, including small rooms and outdoor sites, and then build the cabinets and the secondary equipment inside the cabinets in each small room or outdoor site, including IED devices, switches, and fiber distribution frames, as well as the board and port information of each device. Finally, according to the network topology diagram in the station, design the information logic flow direction of the secondary system, including the starting device port, the switches passed through and the connected switch ports and the terminal device port.

[0098] The graphical information logic diagram is convenient for manual reading, but not for computer parsing. Therefore, in the implementation process, use the information logic diagram configuration tool to record the information logic path in the diagram when designing the information logic diagram and store it in the database. In addition to storing the small room, cabinet, and device information in the database, the actual loop information is mainly stored through the information logic table.

[0099] Use the two-dimensional codes of the optical cable signs and fiber optic labels as the entry for information query, and scan the two-dimensional code on the label through the mobile terminal to obtain the label number information. The mobile terminal quickly retrieves the physical port corresponding to the number, searches for the cable core, fiber core connected to the port and the virtual terminal signal transmitted by the port through the physical port, and quickly locates the physical ports of the devices, switches, and fiber distribution frames passed by the virtual terminal through the virtual terminal information transmitted in the network. The logic block diagram for realizing the "virtual-real correspondence" of the optical fiber cable is as Figure 4 shown.

[0100] In the design stage of secondary equipment on-site at a substation, a physical model of the equipment (including equipment information, board information, and port information) is established, and a physical equipment model is formed according to the hierarchical relationship of compartments, switchboards, equipment, boards, and ports; the loop schematic diagram, virtual loop, and virtual terminals are designed using the physical equipment model, and a physical loop model, secondary design drawings, fiber optic cable inventory, etc. are formed. Fiber optic cable labels (information including fiber optic cable number, cable information, starting point, ending point, and QR code) are formed based on the fiber optic cable physical loop model file of the substation, and a print form is automatically generated for the printing device to selectively print the fiber optic cable labels.

[0101] Both the SCD file and the information logic diagram contain the port information of IED devices, and the two files construct a coupling relationship of virtual-real correspondence through the port information.

[0102] By analyzing the records in the virtual loop table of the database where the control block name, virtual terminal type, sending IED device name, list of all port names of the sending IED device, receiving IED device name, and receiving IED device port name are the same, only one record is extracted for virtual-real correspondence, and all the extracted records are stored in the virtual loop cache;

[0103] By analyzing the receiving IED device and port in the information logic table, search for the same receiving IED device and port in the virtual loop cache;

[0104] Analyze the list of all port names of the sending IED device in the virtual loop cache record found, and search whether the list contains the sending IED device port in the information logic table. If it contains, mark the records in the virtual loop cache and the information logic table as port matching records;

[0105] Analyze the control block name of this record in the virtual loop cache and check whether it exists in the control block name list record in the information logic table. If it does not exist, record it in the control block name list record;

[0106] Mark the records in the information logic table that cannot be matched in the virtual loop cache as mismatches in the physical loop port connection design. Some of the ports in the physical loop port connection mismatches do not transmit virtual terminal signals, and they are uniformly marked as port matching records;

[0107] Mark the records in the virtual loop cache that cannot be matched in the information logic table as mismatches in the virtual loop port connection design;

[0108] Correct the errors of mismatched port connection design through the SCD configuration tool and the information logic diagram configuration tool. When all port connections in the final information logic table and the virtual loop cache match, the virtual-real correspondence design is completed;

[0109] Analyze again the records in the virtual circuit table where the control block name, virtual terminal type, sending IED device name, list of all port names of the sending IED device, receiving IED device name, and receiving IED device port name are the same as those in the virtual circuit cache, and modify the port matching flag to be consistent with the virtual circuit cache.

[0110] The virtual-real correspondence design is the basis for the correct automatic generation of secondary circuits. Taking a 220 kV substation as an example, during the virtual circuit design, about more than 10,000 records will be generated in the virtual circuit table, and during the real circuit design, about 1,000 records will be generated in the information logic table. Through the virtual-real correspondence design, the coupling of virtual and real is completed.

[0111] Perform data fusion and matching on the device board port information in the optical fiber physical model file and the receiving port information of the virtual circuit in the SCD logic model file, construct the matching relationship at the source end of the virtual-real correspondence, automatically generate multiple trace paths from receiving to sending, and bring them into the traversal algorithm model for screening and filtering of various logical judgments. Finally, graphically display the corresponding relationship between the optical fiber physical circuit and the logical circuit, and display the linkage relationship of the data information of virtual terminals, virtual circuits, physical circuit directions, and physical circuit information. By establishing the physical connection data model of IEDs, switches, optical fiber transfer racks, ODFs, optical cables, tail cables, and pigtails in intelligent substations, realize the full-range visualization of the physical connection circuit, output the optical fiber and cable connection diagram, and combine it with the virtual circuit of the intelligent substation to realize the visualization of the virtual-real integrated circuit.

[0112] For the generation of intelligent tags, first establish the models of secondary equipment rooms, switch cabinets, devices in the substation, and the models of substation cables, optical cables, and optical fiber connections. By obtaining the physical circuit configuration information and logical circuit configuration information of the substation, form the corresponding secondary system database of the substation, and organize it into the data format required for later printing and parsing tags to generate model data. Secondly, use tag generation software to traverse the information of cables and optical cables from the database, and generate corresponding optical cable tag files, optical fiber tag files, optical fiber distribution frame tag files, cable tags and other files.

[0113] Among them, the optical cable tag file and the cable tag file output the connection information of the optical cable or cable between switch cabinets according to the switch cabinet, and the optical fiber tag file outputs the device port connection information according to the pigtail or tail cable core and fiber core connected by the optical cable. The generation method of the optical fiber distribution frame tag file is similar to that of the optical fiber tag file.

[0114] When generating two-dimensional code tags, it is necessary to use printing software to edit the tag template according to the optical cable tag format, associate the data in the template with the column data of the tag file, select the data of the tag file to be printed, complete the tag printing, generate two-dimensional code tags, and the tag generation is as Figure 7 shown

[0115] For intelligent label parsing, by obtaining the relevant information stored in the QR code, the QR code storage information of the hanging label, P-type flag label, and spare P-type flag label is as follows:

[0116] The QR code information of the hanging label includes the short name of the power grid area, area short name, substation voltage level number, substation short name, cable, optical cable (or jump cable) number, local end cabinet number, etc. The QR code encoding method is "power grid area short name + area short name + substation voltage level number + substation short name / cable / optical cable (or tail cable) number Cable.name / local end cabinet number Cubicle.name".

[0117] The QR code storage information of the P-type flag label should include ten parts: the short name of the power grid area, area short name, substation voltage level number, substation short name, cable, optical cable (or tail cable) number, cable core, fiber core number, local end cabinet number, device number, board card number, port description, etc. The QR code encoding method should be "power grid area short name + area short name + substation voltage level number + substation short name / cable, optical cable (or tail cable) number Cable.name - cable core, fiber core number Core.no / local end cabinet number Cubicle.name / device number Unit.name / board card number Board.slot /

[0118] Port.no + Port.direction".

[0119] The QR code storage information of the P-type flag label for spare cable cores and fiber cores should include six parts: the short name of the power grid area, area short name, substation voltage level number, substation short name, cable, optical cable (or tail cable) number, etc. The QR code encoding method should be "power grid area short name + area short name + substation voltage level number + substation short name / cable, optical cable (or tail cable) number Cable.name - cable core, fiber core number Core.no".

[0120] By using the QR code as the unique identification code of the device and establishing the corresponding relationship between the device and the QR code information by importing excel, the acquisition of the QR code information of the secondary circuit is realized.

[0121] For the parsing of QR code information, currently, the label format adopts a marking format indicating the number, starting point, and ending point of the optical cable, and some labels also include a brief function description. Due to different transmission principles, the effects of this marking method in conventional substations and intelligent substations are different.

[0122] In a conventional substation, the connection relationships among secondary equipment are marked by combining cable nameplates and core number plates. The cable nameplate describes the start and end of the cable, and the core number plate describes the number of the core cable. By combining with the design drawings, the transmission meaning of each cable can be clearly understood, thus completely presenting the connection relationships among secondary equipment and providing reliable support for project commissioning and operation and maintenance. The cable nameplates of a conventional substation are as shown in Figure 5 as follows.

[0123] In a smart substation, the marking method of a conventional substation is still adopted, and a two-level nameplate method is also used. The optical cable nameplate describes the start and end of the optical cable, and the optical fiber core number plate describes the number and function of the core optical fiber. However, due to the differences in the performance of the cable and optical fiber transmission media, this solution cannot fully support the project commissioning and operation and maintenance work in a smart substation. The optical cable nameplates of a smart substation are as shown in Figure 6 as follows.

[0124] When a cable transmits an electrical signal, each cable transmits an independent signal, and the signal name and function can be simply obtained from the drawing. When an optical fiber transmits a signal, each optical fiber transmits multiple data, which can transmit both analog quantities and switching quantities; the transmission content is not included in the drawing, and the transmission content can only be obtained from the SCD file, and there is no corresponding relationship between the SCD file and the design drawing, so the connection relationships among secondary equipment cannot be completely presented.

[0125] The QR code information parsing process mainly includes the scanning of QR code labels, the download of database files, and the graphical display of database files. The QR code information parsing process mainly includes two major steps: scanning and display:

[0126] (1) Scanning of smart label QR codes. By scanning the QR code on a smart label, according to the type of the QR code, if it belongs to the cable, optical cable, or tail cable QR code, the whole station configuration diagram, the connection diagram of the screen cabinet and optical cable, and the connection diagram of the cable core and optical fiber core will be downloaded from the physical relationship file; if it belongs to the cable core or optical fiber core QR code, the port virtual terminal diagram and the device virtual terminal diagram will be downloaded from the virtual terminal configuration file.

[0127] (2) Display of label QR code information. If it belongs to the cable, optical cable, or tail cable QR code, the physical connection information in the cable will be displayed; if it belongs to the cable core or optical fiber core QR code, the information in the cable core or optical fiber core will be displayed. At the same time, the physical connection information and the virtual terminal information will be displayed correspondingly and automatically associated.

[0128] The mobile terminal quickly recognizes the two-dimensional code intelligent label, realizes the quick recognition of the two-dimensional code of the intelligent label, improves the recognition success rate, and provides technical support for the immediate retrieval of secondary circuit information. The surface of the two-dimensional code intelligent label contains two parts: character information and two-dimensional code information. The character information comes from the relevant information in the physical model. Through the research on the automatic scaling of character size, the character information on the label surface is automatically deployed in a fixed format. The influence of label color and recognition light on the quick recognition of the two-dimensional code is studied, and it is determined that using white as the background of the two-dimensional code will improve the recognition efficiency and accuracy.

[0129] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
