Abstract
Description
Technical Field
[0001] This invention belongs to the field of substation technology, specifically relating to an integrated method for substation physical circuit design and SPCD modeling. Background Technology
[0002] Compared to conventional substations, smart substations based on the DL / T860 standard add a process layer network. The process layer network is composed of IED devices, switches, ODF devices, and optical cables. Various types of substation automation information are transmitted in the process layer network. The GOOSE and SV information transmitted in the process layer network constitute the logical model. Establishing a physical model of the process layer optical fiber network of the smart substation is the basis for realizing the association between the logical model and the physical model, and it is also the basis for the intelligent operation and maintenance of the substation's secondary system.
[0003] Current domestic intelligent substation design models use CAD drawings to represent physical circuits, but these drawings lack information attributes. The design deliverables are electronic drawings, requiring engineers to interpret the information conveyed by the drawings according to agreed-upon rules and text descriptions. Due to the lack of structured geometric and non-geometric data, computers cannot recognize the data. Design units lack the means to digitally transfer substation secondary system model files and cannot provide SPCD model files that describe the physical configuration relationships of the physical circuits. This fails to meet the needs for further in-depth application of the design deliverables in various stages such as engineering construction, operation and maintenance, repair, and dispatch.
[0004] Definitions:
[0005] Physical loop: A general term describing the physical network connections of secondary equipment, also known as a real loop, used to identify the physical connections of secondary loops at the process layer, bay layer, station control layer, and the relationships between them;
[0006] IPCD: Individual Physical Capability Description, a configuration file in XML format that describes the physical capabilities of a single device, including its boards and ports.
[0007] SPCD: Substation Physical Configuration Description, in XML file format, is a configuration file describing the physical circuits of the entire substation.
[0008] KKS coding: Power plant identification system. Because the "Power Grid Engineering Identification System Coding Specification" adopts the KKS coding framework, in this explanation it refers to the power grid engineering identification system. It is a code that clearly identifies the systems, equipment and components in the power grid based on the characteristics of the identified object, such as function, process and installation location. The coding has uniqueness, stability, scalability, compatibility, adaptability, operability and standardization. Summary of the Invention
[0009] In view of this, the purpose of this invention is to provide an integrated method for substation physical circuit design and SPCD modeling, which can effectively improve the efficiency and quality of drawing design and generate SPCD model files.
[0010] To achieve the above objectives, the present invention adopts the following technical solution:
[0011] An integrated method for substation physical circuit design and SPCD modeling includes:
[0012] Build substation basic data on the client side;
[0013] The overall physical loop diagram of the entire station is visualized and drawn using a primitive model with information attributes on the mapping end;
[0014] Based on the physical loop master diagram or physical loop master diagram submitted to the server database, a list of physical loops is generated on the client side, and a preset number of optical distribution ODFs are added in the middle of each physical loop;
[0015] Configure the IPCD model of the secondary device on the client side;
[0016] Based on the physical circuit, the IPCD model port of the secondary device is instantiated and designed.
[0017] Based on the instantiated IPCD model, customized drawing templates for each device are created, automatically converting the database information model into a drawing template at the drafting end.
[0018] Intelligent cabling outputs design drawings and SPCD model files at the level of construction drawings.
[0019] Furthermore, the specific steps for constructing substation basic data on the client side are as follows:
[0020] On the client side, voltage levels, bays, installation units and their locations are created, installation units are systematically classified, and corresponding KKS codes are configured using faceted classification.
[0021] Set the area location and associated intervals of the installation unit;
[0022] The acquired basic data of the substations is stored in a database.
[0023] Furthermore, the step of drawing the overall physical loop diagram of the entire station using a primitive model with information attributes at the mapping end also includes:
[0024] The equipment is classified and coded using a facet classification method;
[0025] All objects in the physical loop diagram are divided into two main categories: devices and connections.
[0026] The starting and ending devices of the physical loops are determined according to the sequence of the starting and ending points of the physical loop connections drawn by the drawing terminal. The physical loop connections are drawn in pairs, and the direction attributes of the transmit and receive ports are automatically determined. Between devices that only receive or transmit, one loop is required to be deleted.
[0027] In the physical circuit diagram, the devices are single general-purpose boards in the scheme or preliminary design stage, and the ports are automatically coded with serial numbers according to the order in which the devices are drawn.
[0028] The graph information is transformed into an information model and submitted to the server database for storage. Then, by combining graph theory knowledge, the secondary devices and their connection relationships are traversed to construct the global topology of the physical loop.
[0029] Furthermore, the physical loop master diagram based on the mapping end or the physical loop master diagram submitted to the server database generates a physical loop list on the client side, and a preset number of optical distribution ODFs are added in the middle of each physical loop, including the following two methods:
[0030] ① On the drawing end, call the optical ODF model created by the client, and add a preset number of optical ODFs to the physical loop in the drawing method. Specifically, add a preset number of optical ODFs to the physical loop on the drawing end in the form of straight lines or dots that are orthogonal to the lines connecting the physical loops. Multiple orthogonal straight lines or multiple dots are allowed to be drawn for one physical loop.
[0031] Submit the overall physical loop diagram after adding the optical ODF to the database, and generate a list of physical loops including the optical ODF on the client.
[0032] ② Submit the physical loop master diagram to the database, generate a list of each physical loop on the client, and add a preset number of optical distribution ODFs in the middle of each physical loop list;
[0033] The system dimension tree directory is constructed by substation, voltage level, bay, and equipment, which serves as the index tree for the physical loop list. The bay point displays all physical loops starting or ending at the equipment under the bay, and the equipment point displays all physical loops starting or ending at the equipment.
[0034] Set the ODF count of physical loops with origin and destination devices on the same screen and in the same small room to 0, and default to direct connection via jumper, pigtail, and tail cable;
[0035] The ODF files can be categorized into origin device cabinet ODF, transit ODF, and destination device cabinet ODF. ODF files for origin and destination devices cabinets are automatically filtered out. Transit ODF files are not filtered and are selected from all ODF files on the site.
[0036] Preferably, in this embodiment, configuring the IPCD model of the secondary device on the client side further includes:
[0037] Manual creation is based on secondary equipment. According to the secondary optical circuit backplane diagram of the secondary equipment provided by the engineering supplier, the board and port are created in a visual way. File import is a standard format IPCD file provided by the equipment manufacturer. The configuration is completed by one-click import based on a single device.
[0038] Copy the pre-configured IPCD model of the device and paste it in batches to devices of the same type to complete the IPCD modeling of all devices of the same type.
[0039] Furthermore, the instantiation design of the secondary device IPCD model port based on the physical loop includes the instantiation of the physical loop start and end point devices, the instantiation of the optical distribution ODF port, the parallel design of the physical loop ODF port, and the replication of the port instance, specifically:
[0040] Physical loop start and end point device instantiation: Using a visual drag-and-drop method, the device's IPCD port is dragged to each physical loop where the device is located, establishing the association between the device's IPCD port and the physical loop where the device is located;
[0041] Optical ODF port instantiation: Visually move each physical loop up and down to adjust its port position on the ODF;
[0042] Parallel design of physical loop ODF ports: After the ODF design of the starting equipment cabinet is completed, the next ODF connected in sequence will automatically match the port of the previous ODF to complete the design.
[0043] Port instance copying: Based on the principle of the same loop type identifier, the completed interval design is copied and pasted to another interval. For loops that span intervals, ports of devices outside the current interval are not copied.
[0044] Furthermore, the automatic conversion from the database information model to the cartographic map model specifically involves:
[0045] (1) The instantiated IPCD model includes devices, boards, ports and their connection relationships. The intelligent drawing output of the drawing end adopts a standardized customized template, which consists of boards and fiber cores that represent physical circuits;
[0046] (2) The graphic elements of pigtails, pigtails, and optical cables adopt a general format or are customized by the designers. The graphic elements of pigtails, pigtails, and optical cables have labels such as core count, model, and destination. The labels are associated with the attributes of the information model and are automatically generated, and the graphic model is consistent.
[0047] Furthermore, throughout the entire design and modeling process, model verification can be performed at any time or in stages as needed, and SPCD model generation and verification can be carried out.
[0048] Furthermore, the model verification includes physical loop repeatability verification, device code uniqueness verification, connection type verification between different types of devices, and optical cable number uniqueness verification.
[0049] Furthermore, the SPCD model generation and verification specifically involves generating a standard-compliant SPCD model file based on information about substations, areas, cabinets, secondary equipment, boards, ports, and the connection relationships between devices, and verifying the correctness of the SPCD model.
[0050] Compared with the prior art, the present invention has the following advantages:
[0051] This invention can improve the efficiency and quality of drawing design while simultaneously outputting design drawings and SPCD model results in one integrated manner. Attached Figure Description

[0056] Figure 5 This is a schematic diagram of the physical circuit identification attributes in one embodiment of the present invention. Detailed Implementation
[0057] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0058] Please refer to Figure 1In this embodiment, the preferred drafting terminal is CAD, specifically including:
[0059] On the client side, voltage levels, bays, installation units and their locations are created to establish basic substation data, which is then stored in the database.
[0060] Create secondary equipment such as IED devices and SWITCH switches, and draw the overall physical circuit diagram of the entire substation's secondary equipment: Draw the overall physical circuit diagram of the entire substation using graphic element models with information attributes in the CAD terminal. The diagram only shows the substation's IED devices, SWITCH switches, and directional connection lines; the graphic elements of different types of equipment all use a single geometric shape and are distinguished by text labels.
[0061] Inserting optical distribution ODFs into physical loops: Submit the overall physical loop diagram to the server database, generate a list of each physical loop on the client, add a preset number of optical distribution ODFs in the middle of each physical loop list to complete the physical loop list; or on the CAD side, insert optical distribution ODFs as primitive models, submit to the server database, and generate a complete physical loop list containing optical distribution ODFs on the client.
[0062] Establish the association between secondary equipment and IPCD model: Based on the equipment data of the engineering supplier, manually create or import the IPCD model of IED equipment, SWITCH switch, optical distribution ODF and other equipment on the client side;
[0063] Device port instantiation of physical loop: The improved physical loop includes IED devices, SWITCH devices and ODF devices. Based on the physical loop, the IPCD model ports of the secondary devices are instantiated and designed.
[0064] Intelligent drawing output and intelligent cabling: Based on the complete information model of the client's physical circuit, customized drawing templates for each device (IED equipment, ODF, SWITCH) are generated, automatically converting the database information model into CAD drawing models and outputting design drawings with construction drawing depth.
[0065] Preferably, in this embodiment, the method further includes information model result verification and output: automatically generating SPCD files according to SPCD file rules.
[0066] Preferably, in this embodiment, voltage levels, intervals, installation units and their locations are created on the client side, the installation units are systematically classified, and the corresponding KKS codes are configured using the face classification method;
[0067] Set the area location and associated intervals of the installation unit;
[0068] The acquired basic data of the substations is stored in a database.
[0069] Preferably, in this embodiment, drawing the overall physical loop diagram of the entire station using a primitive model with information attributes at the mapping end further includes:
[0070] The equipment is classified and coded using a faceted classification method to ensure that each piece of equipment has a unique identifier in the project space. For each piece of equipment, it is first classified from the system dimension according to "plant, voltage level, bay, equipment", and then classified from the installation location dimension according to "area (room) location, installation unit, equipment".
[0071] All objects in the physical loop diagram are divided into two main categories: devices and connections. Device objects are further subdivided into two types: IED and SWICH. IED devices are further subdivided by profession or function. Physical loop connections are divided into different loop types such as GOOSE Network A, GOOSE Network B, SV Network A, SV Network B, Direct Procurement A, Direct Jump A, Direct Procurement B, Direct Jump B, Cascade A, Cascade B, Time Synchronization A, and Time Synchronization B.
[0072] The starting and ending devices of the physical loops are determined according to the sequence of the starting and ending points of the physical loop connections drawn on the CAD end. The physical loop connections are drawn in pairs, and the direction attributes of the transmit and receive ports are automatically determined. Between devices that only transmit or receive, one loop is required to be deleted.
[0073] In the physical circuit diagram, the devices are single general-purpose boards in the scheme or preliminary design stage. The ports are automatically coded with serial numbers according to the order in which the devices are drawn. This can be represented as one device with one element or multiple elements. When drawing the circuit, they can be flexibly distributed in different drawing modules and arranged freely by the designer according to their habits.
[0074] In this embodiment, the diagram is drawn in intervals, that is, the common equipment in each interval can be arranged with corresponding elements in each interval. The circuit diagram is drawn in intervals, which makes it easier to classify equipment into intervals and to make it easier to replicate the same type of interval, thus improving its engineering reusability.
[0075] The graph information is transformed into an information model and submitted to the server database for storage. Then, by combining graph theory knowledge, the secondary devices and their connection relationships are traversed to construct the global topology of the physical loop.
[0076] Based on the global topology of the physical loop, the physical loops of the origin and destination devices and their loop types are determined. The information flow is uniquely identified and automatically matched to present the information in a visual manner.
[0077] Preferably, in this embodiment, based on the overall physical loop diagram, a list of physical loops is generated on the client side, and a preset number of optical distribution ODFs are added in the middle of each physical loop list. The method further includes:
[0078] The system uses a tree-like directory of "plant, voltage level, bay, and equipment" as the index tree for the list of physical loops. Clicking "bay" displays all physical loops starting or ending at the equipment under that bay, and clicking "equipment" displays all physical loops starting or ending at that equipment. It can insert ODF by bay and view the loop ODF by equipment.
[0079] Set the ODF quantity of physical loops with origin and destination devices on the same screen and in the same small room to "0", and the default is to connect directly via jumper, pigtail, or pigtail cable;
[0080] The ODF files are categorized into origin equipment cabinet ODF, transit ODF, and destination equipment cabinet ODF. ODF files for origin and destination equipment cabinets are automatically filtered out. Transit ODF files are not filtered and are selected from all ODF files on the site.
[0081] The physical loop list includes fields such as "serial number, loop type, single or dual network, information set, number of ODFs, starting device, starting device cabinet ODF, information flow direction, transit ODF, ending device cabinet ODF, and ending device". Field filtering can simplify design objectives, such as single or dual network filtering, or simply designing network A or network B.
[0082] Preferably, in this embodiment, configuring the IPCD model of the secondary device on the client side further includes:
[0083] Manual creation is based on the equipment. According to the secondary optical loop backplane diagram of the equipment provided by the engineering supplier, the board and port are created in a visual way. File import is based on the standard format IPCD file provided by the equipment manufacturer. The configuration is completed by one-click import based on a single device.
[0084] Copy the pre-configured IPCD model of the device and paste it in batches to devices of the same type to complete the IPCD modeling of all devices of the same type.
[0085] Preferably, in this embodiment, the physical loop device port instantiation includes physical loop origin / end point device instantiation, optical distribution ODF port instantiation, physical loop ODF port parallel design, and port instance replication, specifically:
[0086] Physical loop start and end point device instantiation: Using a visual drag-and-drop method, the device's IPCD port is dragged to each physical loop where the device is located, establishing the association between the device's IPCD port and the physical loop where the device is located, thus realizing port instance design.
[0087] In this embodiment, a list of device board ports is generated and displayed in separate left and right lists with the physical circuit details starting or ending with this device. Designers can drag the board ports to the corresponding physical circuits to complete the instantiation of the board ports.
[0088] Optical Distribution Provider (ODF) Port Instantiation: After the ODF physical loop insertion operation, the physical loop has been associated with the ODF. Instantiating the optical distribution provider's ODF port only requires moving each physical loop up and down to adjust its position on the ODF port. In this embodiment, the ODF board port list and the list of physical loops processed by this optical distribution provider are arranged horizontally. Adjusting the order of the physical loops in the list so that a physical loop and a port are on the same row means that the port is instantiated by that physical loop.
[0089] Parallel design of physical loop ODF ports: Based on the characteristic that the board numbers of the starting device cabinet ODF ports, transit ODF ports, and ending device cabinet ODF ports of the physical loop are not required and the port numbers are consistent, once the starting device cabinet ODF design is completed, the subsequent ODF simply copies the port of the previous ODF to complete the design.
[0090] Port instance copying: If the voltage level, bay type, equipment type and model, and number of equipment sets are identical between two bays, and the circuit identifier is the same, copy and paste the completed bay design to the other bay. For circuits spanning bays, do not copy ports of equipment not belonging to this bay. The physical circuit type identifier definition is as follows: Figure 5 As shown.
[0091] Preferably, in this embodiment, intelligent image generation specifically includes:
[0092] (1) The instantiated IPCD model includes devices, boards, ports and their connection relationships. The intelligent output of the drawing end adopts standardized customization and is composed of boards and fiber cores that represent physical circuits.
[0093] (2) The graphic elements of pigtails, pigtails, and optical cables adopt a general format or are customized by the designers. The graphic elements of pigtails, pigtails, and optical cables have labels such as core count, model, and destination. The labels are associated with the attributes of the information model and are automatically generated, and the graphic model is consistent.
[0094] Preferably, in this embodiment, model verification includes physical loop repeatability verification, device code uniqueness verification, connection type verification between different types of devices, and optical cable number uniqueness verification.
[0095] SPCD model generation and verification specifically involves generating SPCD model files conforming to the IEC 61850 standard based on information about substations, regions, cabinets, secondary equipment, boards, ports, and the connections between devices. These files include Substation\Region\Cubile\Unit\Board\Port\Cable\Core\Incore. The correctness of the SPCD model is then verified.
