Description

Technical Field

[0001] This invention relates to the field of intelligent operation and maintenance of power system substations, and in particular to a method and system for bay association of primary and secondary equipment. Background Technology

[0002] The IEC 61850 standard is the foundation for the construction of smart substations. The standard defines the System Specification Description (SSD) file for the entire substation, which describes the primary system structure and the relationships between primary and secondary equipment. Through the relationships between primary and secondary equipment, information such as which secondary equipment (LN) is associated with a certain primary equipment and which secondary equipment (LN) is associated with the same bay can be obtained. However, since there is currently no mature and standardized method for associating primary and secondary equipment, it objectively brings great obstacles to the application of SSD files. Relying entirely on manual configuration is very labor-intensive, which has resulted in the limited application of SSDs in actual projects.

[0003] In recent years, advanced application technologies for smart substation operation and maintenance have been continuously developing. Advanced application functions based on primary and secondary equipment information, such as source comparison analysis of analog and switching quantities of the same primary equipment and corresponding monitoring of primary and secondary equipment status, all require the establishment of correlations between primary and secondary equipment. Unclear correlations between primary and secondary equipment result in a poor data foundation for advanced applications based on the status of primary and secondary equipment and the status information between secondary equipment within a bay. All configuration processes directly deal with instantiated specific device models, and the configuration results of a single bay are completely unusable. Signals need to be configured one by one for each bay and each application function, resulting in extremely low configuration efficiency and difficulty in guaranteeing configuration accuracy. Once the model of a certain device changes, the related configuration work needs to be completed again.

[0004] Therefore, there is an urgent need to study automatic association methods for primary and secondary equipment in smart substations, and to promote the practical application level of advanced intelligent application functions based on primary and secondary equipment information in smart substations. The paper "An Automatic Association Method for Primary and Secondary Equipment Models in Smart Substations" (application number 202011122671.7) proposes an automatic association method for primary and secondary equipment models in smart substations. This method associates the CID file of a single-bay secondary equipment with the corresponding primary bay in the SSD file. It achieves the association between secondary equipment across bays and the primary bay by setting a dedicated primary bay association LN. However, this method requires manually associating each single-bay secondary equipment with the relevant primary bay in the SSD file. For cross-bay equipment, it requires assigning the value of each bay name (DO) in the dedicated bay association LN to the corresponding actual bay name (name) in the SSD file to complete the bay association. This method is labor-intensive and does not achieve automation at the bay association level. The patent application "An Automatic Association Method and Device for Primary and Secondary Equipment Bays in Intelligent Substations" (application number 202110702658.7) discloses an automatic association method for primary and secondary equipment bays in intelligent substations. This method names the IEDs (Initial Equipment Panels) based on their secondary equipment type, bay type, voltage level, bay number, and set number. It then configures English names for each bay in the SSD (Secondary Equipment Storage) file based on the bay type, voltage level, and bay number. Based on the IED names and the English names of each bay in the SSD file, and according to the matching relationship between the primary and secondary equipment's bay type, voltage level, and bay number, the IEDs are associated with the relevant primary bays in the SSD file. This method requires that the primary and secondary equipment names have the same English description; otherwise, automatic association of primary and secondary equipment bays cannot be achieved. This is relatively easy to implement for single-bay equipment, but for cross-bay equipment, requiring the sub-bay descriptions to be consistent with the primary bay descriptions is difficult to achieve. Therefore, further research is needed to develop more general methods to achieve automatic association between secondary equipment and related primary bays.

[0005] In the existing technology, the association between primary and secondary equipment still needs to be done manually, which will result in a considerable amount of manual work and the reliability is difficult to guarantee. Automatic association through the English description of the interval also has certain limitations, especially for cross-interval equipment, which is very difficult to achieve. Summary of the Invention

[0006] The purpose of this application is to propose a method and system for inter-interval association of primary and secondary equipment, which solves the problems of large manual workload and difficulty in inter-interval association of primary and secondary equipment in the prior art.

[0008] According to some embodiments, the CPD file of the primary terminal box contains name attribute information for a primary interval, and is consistent with the name attribute information for a primary interval Bay in the SSD file.

[0009] According to some embodiments, in the creation of the SCD file, for secondary devices using digital sampling methods connected by optical cables, it is also necessary to complete the configuration of virtual terminal connections.

[0013] According to a second aspect of this application, an automatic association system for primary and secondary equipment and bays in a substation is proposed, the system comprising: The SSD file acquisition unit is used to create a system specification description SSD file for the entire substation, modeling and describing the primary bays and main wiring of the substation; configuring the name attribute of each primary bay Bay element and ensuring that it is unique throughout the entire substation; The IPD and ICD file acquisition unit is used to acquire the single-device physical description (IPD) file and capability description (ICD) file of each secondary device. The CPD file acquisition unit is used to create physical description CPD files for the primary terminal boxes and secondary equipment cabinets of each primary interval, and to model the physical circuit. The SPD file acquisition unit is used to create a substation physical description SPD file for the entire station and to model the physical circuit of the cross-screen cabinet. The name attribute of the Bay element in the SPD file is consistent with the name attribute of the Bay element in the SSD file. The SCD file acquisition unit is used to create a full-site system configuration description SCD file based on the SSD file, IPD file, ICD file, CPD file and SPD file; The single-interval device interval association unit is used to determine the interval association of a single-interval device based on the name attribute of the Bay element in the SSD file and SPD file; The cross-bay equipment bay association unit is used to determine the primary terminal boxes that are connected to the cross-bay equipment based on the IPD file, CPD file and SPD file, and to determine the bay association of the cross-bay equipment based on the name attribute of Bay in the SPD file and the CPD file of the primary terminal box.

[0014] According to some embodiments, establishing the interval association of a single-interval device based on the name attribute of the Bay element in the SSD file and the SPD file includes: In the SSD file, match the interval that matches the name attribute of the Bay element in the SPD file to determine the interval associated with each Bay element in the SPD file. By identifying the DeviceRef attribute of the secondary device information in the Bay element of the SPD file, the secondary device associated with the primary interval can be determined.

[0015] According to some embodiments, when the sampling method of the secondary equipment is cable sampling, the cross-interval equipment interval association unit specifically includes: Based on the IPD file of the cross-segment device, determine each sub-segment and the corresponding device connection point (Pin) element; Based on the connection Core element in the CPD file of the secondary equipment cabinet, determine the cabinet terminals connected to each sub-bay; Based on the cable attribute of the SPD file, identify the primary terminal box that has a cable connection with the cabinet terminal. In the SSD file, match the primary interval that matches the name attribute of Bay in the CPD file of the primary terminal box to determine the primary interval associated with each sub-interval.

[0016] According to some embodiments, when the sampling method of the secondary device is digital sampling, the cross-interval device interval association unit specifically includes: Based on the ICD file of the cross-bay device, determine each sub-bay and the corresponding virtual terminal of the sub-bay; Based on the virtual terminal connection relationships in the SCD file, determine the process layer devices connected to each sub-bay of the cross-bay device; Based on the connection point Pin element in the IPD file of the process layer equipment and the connection Core element in the CPD file of the process layer cabinet, determine the cabinet terminals connected to each process layer equipment.

[0019] After adopting the above solution, the beneficial effects of the present invention compared with the prior art are: The physical circuit digital modeling file is a file provided in advance during the design and construction of substations. Based on the existing modeling file, this invention completes the automatic association of primary bays and their secondary equipment, integrating the association work of primary and secondary equipment into the substation design process. This eliminates the need for additional manual work, greatly improves the efficiency of the association, and lays a good data foundation for further development of advanced substation operation and maintenance functions.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The applicant found that when dealing with the problem of inter-interval association between primary and secondary equipment, the existing technology still requires manual association, which will bring a considerable amount of manual work and make it difficult to guarantee reliability, especially for cross-interval equipment, which is very difficult to implement.

[0023] Digital substations use SV (sample value) for analog signal sampling and transmission, and GOOSE (generic object-oriented substation event) for digital signal input and output. The SCD file is a model representation of the logic loops of the secondary system in a digital substation. These logic loops, also known as "virtual loops," describe the signal connection relationships between intelligent devices in a digital substation, analogous to cable loops in a conventional substation. In a digital substation, the physical loops corresponding to these "virtual loops" are fiber optic connection loops. Digital signals such as SV and GOOSE are transmitted between intelligent devices through these physical fiber optic loops, according to the signal connection relationships in the "virtual loops."

[0024] For physical circuits, especially cable circuits in conventional substations, industry experts have begun to study digital modeling technology in recent years and have formulated relevant specifications for digital modeling design of substation physical circuits. These specifications standardize modeling rules for secondary equipment physical circuit interfaces, cabinet digital design, and the entire substation's secondary circuits. The physical circuit digital model files, i.e., the substation digital design files, include Individual Physical Description Files (IPDs), Cabinet Physical Description Files (CPDs), and Substation Physical Description Files (SPDs), all in XML file format.

[0025] The Individual Device Physical Description (IPD) file describes the equipment configuration of secondary equipment, including physical capabilities such as boards and ports. It uses a structured model to represent the hierarchical relationships between elements such as Device, Subdevice, Part, Component, and Pin. The Cabinet Physical Description (CPD) file describes the equipment configuration of the cabinet, including secondary equipment, pressure plates, cabinet terminals, and internal wiring relationships. Its hierarchical structure includes elements such as Cabinet, Device, Function Area, Core, Interface, and Point. The Substation Digital Design Description (SPD) file, built upon the IPD and CPD files, is a design configuration file describing the physical configuration and connection topology of the substation's secondary circuits. Its hierarchical structure includes elements such as Substation Description, Region, Cabinet, Bay, DeviceRef, and Cable.

[0026] Digital modeling of substation physical circuits lays the foundation for improving the efficiency and quality of substation manufacturing, design, construction, commissioning, operation and maintenance, and paves the way for further automatic association of primary and secondary equipment bays.

[0027] In view of this, the applicant proposes an automatic association method for primary and secondary equipment and bays in substations, which is combined with the digital design of substations, naturally integrating the association of primary and secondary equipment into the digital design. For example... Figure 1 The flowchart shown illustrates the following steps in the method: S100: Create a system specification description SSD file for the entire substation, modeling and describing the primary bays and main wiring of the substation; configure the name attribute of the Bay element of each primary bay, and ensure that it is unique throughout the entire substation.

[0028] The SSD file carries one-time interval information through the Bay element. The name of the interval adopts the name of the main equipment contained in the interval, such as CBR1011, CBR1021, etc. Specific modeling requirements can be implemented in accordance with the "DL / T 1874—2018 Technical Specification for Modeling Engineering Implementation of Intelligent Substation System Specification Description (SSD)".

[0029] S200: Obtain the individual device physical description (IPD) file and capability description (ICD) file for each secondary device.

[0030] IPD files describe the physical interface information of a single device, and their hierarchical structure is as follows: Figure 2As shown, the main components include Device elements, Part elements, and Pin elements. Pin elements represent connection points on electrical components that allow external connections, such as terminal blocks, fiber optic interfaces, and Ethernet ports.

[0031] The Physical Description Device (IPD) files for a single device are provided by the equipment manufacturer. Therefore, this step should collect the IPD files for all secondary equipment in the station for subsequent SPD integration.

[0032] ICD files are equipment capability description files provided by the equipment manufacturer. Their modeling principles can refer to relevant standards, such as the "IEC 61850 Engineering Relay Protection Application Model". For cable sampling devices, the ICD file mainly provides the communication information interface for the station control layer; for optical cable sampling devices, it also provides process layer input and output virtual terminals for connecting to external devices when creating SCD files.

[0033] S300: Create physical description (CPD) files for the primary terminal boxes and secondary equipment cabinets of each primary bay, and model the physical circuits.

[0034] CPD files describe the physical circuits within the cabinet, and their hierarchical structure is as follows: Figure 3 As shown, the main components include Device, Function Area, and Core. The Core element describes the connection relationships between terminals within the cabinet.

[0035] The terminal box CPD file contains the name attribute information for each interval, and it is consistent with the name attribute information for each interval Bay in the SSD file.

[0036] S400: Creates a substation physical description (SPD) file for the entire substation, models the physical circuits of cross-panel cabinets, and the name attribute of the Bay element in the SPD file is consistent with the name attribute of the Bay element in the SSD file.

[0037] The SPD file describes the physical loops of the entire station, and its hierarchical structure is as follows: Figure 4 As shown, it mainly includes elements such as Cubicle, Bay, DeviceRef, Cable, and Core.

[0038] The interval Bay contains a reference to the secondary device DeviceRef, and its name attribute should be consistent with the name of the SSD primary interval Bay, such as CBR1011 and CBR1021 in step S100.

[0039] The Cable element represents the cable used to connect the cabinets. It carries the name of the cable and the names of the cabinets at both ends of the cable. The connection relationship between the cabinets can be determined by searching the Cable element.

[0040] S500: Create a full-site system configuration description SCD file based on the SSD file, IPD file, ICD file, CPD file and SPD file.

[0041] In some embodiments, a digital sampling method using optical fiber connection is employed. For this part of the secondary equipment, the configuration of virtual terminal connection should also be completed.

[0042] S600: Determines the interval association of a single-interval device based on the name attribute of the Bay element in the SSD file and SPD file.

[0043] In some embodiments, the following steps are specifically included: S601: Match an interval in the SSD file that matches the name attribute of the Bay element in the SPD file, thereby determining the interval associated with each Bay element in the SPD file. S602: By identifying the DeviceRef attribute of the secondary device information in the Bay element of the SPD file, the secondary device associated with the primary interval is determined.

[0044] After the above two steps, the interval relationship of a single-interval device can be determined.

[0045] For example, if a Bay in the SPD file has the name attribute "CBR1101", the SSD file will search for the Bay with the same name attribute "CBR1101". This will determine the primary bay associated with the Bay in the SPD file whose name attribute is "CBR1101". Based on the SPD file, the Bay with the name attribute "CBR1101" is identified, and its associated secondary device DeviceRef value is "PCS-931". Therefore, this single-bay secondary device "PCS-931" is associated with the primary bay CBR1101.

[0046] S700: Based on the IPD file, CPD file and SPD file, determine the primary terminal box that is connected to the cross-bay device, and based on the SPD file and the Bay name attribute in the CPD file of the primary terminal box, determine the bay association of the cross-bay device.

[0047] In some embodiments, the sampling method of the secondary equipment is cable sampling. The cross-bay secondary equipment using cable sampling is characterized by being directly connected to the primary bay via a cable. When the sampling method of the secondary equipment is cable, the bay association of the cross-bay sampling equipment specifically includes: S711: Based on the IPD file of the cross-segment device, determine each sub-segment and the corresponding device connection point Pin element; S712: Determine the cabinet terminals connected to each sub-bay based on the connection Core element in the CPD file of the secondary equipment cabinet; S713: Based on the Cable attribute of the SPD file, determine the primary terminal box that has a cable connection with the cabinet terminal; S714: Match the primary interval in the SSD file with the name attribute of Bay in the CPD file of the primary terminal box, thereby determining the primary interval associated with each sub-interval.

[0048] After the above steps, the association between a primary interval and a cross-interval equipment sub-interval can be established.

[0049] like Figure 5 As shown, based on the branch current description associated with the AC sampling terminal Pin defined in the IPD file of a cable sampling cross-bay device, the AC sampling terminal corresponding to "Branch 1 Current" in sub-bay 1 and the AC sampling terminal corresponding to "Branch 2 Current" in sub-bay 2 can be determined. In the CPD file of the protection cabinet where this device is located, the Core element describes the cabinet terminals to which the AC sampling terminals are connected. Therefore, it can be determined that "Branch 1 Current" in sub-bay 1 is connected to terminal blocks 1D1~1D4 of the cabinet, and "Branch 2 Current" in sub-bay 2 is connected to terminal blocks 2D1~2D4 of the cabinet.

[0050] Searching the entire site's SPD files, based on the Cable attribute, it can be identified that cabinet terminals 1D1~1D4 are connected to primary terminal box 1's terminals 1D1~1D4, and cabinet terminals 2D1~2D4 are connected to primary terminal box 2's terminals 1D1~1D4.

[0051] In the CPD file of primary terminal box 1, terminals 1D1~1D4 are represented as switch CBR1011, meaning the name attribute of the Bay is CBR1011. By searching the SSD file for primary device CBR1011 with the name attribute of Bay and its related primary devices, the association between sub-bay 1 (cross-bay device) and primary bay can be established. In the CPD file of primary terminal box 2, terminals 1D1~1D4 are represented as switch CBR1021, meaning the name attribute of the Bay is CBR1021. By searching the SSD file for primary device CBR1021 with the name attribute of Bay and its related primary devices, the association between sub-bay 2 (cross-bay device) and primary bay can be established.

[0052] In some embodiments, the sampling method of the secondary equipment is digital sampling. For digitally sampled cross-interval secondary equipment, the primary interval is directly connected to the process layer equipment, and the process layer equipment is then connected to the interval layer equipment via an optical fiber loop. The process layer equipment is modeled in the process layer cabinet CPD file, and the interval layer equipment is modeled in the interval layer cabinet CPD file. When the sampling method of the secondary equipment is digital sampling, the interval association of cross-interval equipment specifically includes: S721: Based on the ICD file of the cross-bay device, determine each sub-bay and the corresponding virtual terminal of the sub-bay; S722: Based on the virtual terminal connection relationship in the SCD file, determine the process layer equipment connected to each sub-bay of the cross-bay equipment; S723: Determine the cabinet terminals connected to each process layer device based on the connection point Pin element in the IPD file of the process layer device and the connection Core element in the CPD file of the process layer cabinet. S724: Based on the cable attributes in the SPD file, determine the primary terminal box connected to the process layer cabinet; S725: Match the primary interval in the SSD file with the name attribute of Bay in the CPD file of the primary terminal box, thereby determining the primary interval associated with each sub-interval.

[0053] After the above steps, the association between a primary interval and a cross-interval equipment sub-interval can be established.

[0054] like Figure 6 As shown, based on the branch current description of the AC sampling virtual terminal defined in the ICD file of a certain optical cable sampling cross-segment device, the virtual terminal corresponding to "Branch 1 Current" in sub-segment 1 and the virtual terminal corresponding to "Branch 2 Current" in sub-segment 2 can be determined. Based on the virtual terminal connection relationship in the SCD file, the connection relationship of the current virtual terminals is identified, revealing that the virtual terminal of "Branch 1 Current" in sub-segment 1 is connected to process layer device 1, and the virtual terminal of "Branch 2 Current" in sub-segment 2 is connected to process layer device 2.

[0055] Based on the connection point Pin element of the IPD file of process layer device 1 and the Core element of the CPD file of process layer cabinet 1 where process layer device 1 is located, it can be identified that the virtual terminal corresponding to "branch 1 current" of sub-interval 1 is connected to terminal blocks 1D1~1D4 of the cabinet. Based on the connection point Pin element of the IPD file of process layer device 2 and the Core element of the CPD file of process layer cabinet 2 where process layer device 2 is located, it can be identified that the virtual terminal corresponding to "branch 2 current" of sub-interval 2 is connected to terminal blocks 1D1~1D4 of the cabinet.

[0056] Searching the entire site's SPD files, based on the Cable attribute, it can be identified that terminals 1D1~1D4 of process layer cabinet 1 are connected to terminals 1D1~1D4 of primary terminal box 1; and terminals 1D1~1D4 of process layer cabinet 2 are connected to terminals 1D1~1D4 of primary terminal box 2.

[0057] In the CPD file of primary terminal box 1, terminals 1D1~1D4 are represented as switch CBR1011, meaning the name attribute of the Bay is CBR1011. By searching the SSD file for primary device CBR1011 with the name attribute of Bay and its related primary devices, the association between sub-bay 1 and the primary bay can be established. In the CPD file of primary terminal box 2, terminals 1D1~1D4 are represented as switch CBR1021, meaning the name attribute of the Bay is CBR1021. By searching the SSD file for primary device CBR1021 with the name attribute of Bay and its related primary devices, the association between sub-bay 2 and the primary bay can be established.

[0058] like Figure 7 The image shows an embodiment of an automatic association system 800 for primary and secondary equipment and bays in a substation, comprising: an SSD file acquisition unit 801, an IPD and ICD file acquisition unit 802, a CPD file acquisition unit 803, an SPD file acquisition unit 804, an SCD file acquisition unit 805, a single-bay equipment bay association unit 806, and a cross-bay equipment bay association unit 807. Wherein: SSD file acquisition unit 801 is used to create a system specification description SSD file for the entire substation, model and describe the primary bays and main wiring of the substation; configure the name attribute of the Bay element of each primary bay, and ensure that it is unique throughout the entire substation.

[0060] CPD file acquisition unit 803 is used to create physical description CPD files for primary terminal boxes and secondary equipment cabinets in each primary interval, and to model the physical circuit.

[0061] SPD file acquisition unit 804 is used to create a substation physical description SPD file for the entire station and to model the physical circuit of the cross-screen cabinet. The name attribute of the Bay element in the SPD file is consistent with the name attribute of the Bay element in the SSD file.

[0062] The SCD file acquisition unit 805 is used to create a full-site system configuration description SCD file based on the SSD file, IPD file, ICD file, CPD file and SPD file.

[0063] The single-interval device interval association unit 806 is used to determine the interval association of a single-interval device based on the name attribute of the Bay element in the SSD file and SPD file.

[0065] In some embodiments, establishing the interval association of a single-interval device based on the name attribute of the Bay element in the SSD file and the SPD file includes: matching a primary interval in the SSD file that matches the name attribute of the Bay element in the SPD file, thereby determining the primary interval associated with each Bay element in the SPD file. The secondary device associated with the primary interval is determined by identifying the DeviceRef attribute of the Bay element in the SPD file.

[0066] In some embodiments, when the sampling method of the secondary equipment is cable sampling, the cross-bay equipment interval association unit specifically includes: determining each sub-bay and the corresponding equipment connection point Pin element according to the IPD file of the cross-bay equipment; Based on the connection Core element in the CPD file of the secondary equipment cabinet, determine the cabinet terminals connected to each sub-bay; Based on the cable attribute of the SPD file, identify the primary terminal box that has a cable connection with the cabinet terminal. In the SSD file, match the primary interval that matches the name attribute of Bay in the CPD file of the primary terminal box to determine the primary interval associated with each sub-interval.

[0067] In some embodiments, when the sampling method of the secondary device is digital sampling, the cross-interval device interval association unit specifically includes: Based on the ICD file of the cross-bay device, determine each sub-bay and the corresponding virtual terminal of the sub-bay; Based on the virtual terminal connection relationships in the SCD file, determine the process layer devices connected to each sub-bay of the cross-bay device; Based on the connection point Pin element in the IPD file of the process layer equipment and the connection Core element in the CPD file of the process layer cabinet, determine the cabinet terminals connected to each process layer equipment. Based on the cable attributes in the SPD file, determine the primary terminal box connected to the process layer cabinet; In the SSD file, match the primary interval that matches the name attribute of Bay in the CPD file of the primary terminal box to determine the primary interval associated with each sub-interval.
