Description

Technical Field

[0001] The invention belongs to the field of substation design, and in particular relates to a three-dimensional refined rapid modeling method for a relay protection panel cabinet based on a GIM format. Background Art

[0002] With the continuous development of information technology, digital technology, and intelligent technology, the design of power transmission and transformation projects in my country has gradually developed from two-dimensional to three-dimensional. The electrical department urgently needs to establish a data exchange format for electrical equipment that meets the requirements of full life cycle data sharing and unified model architecture. In this context, the GIM (Grid Information Model) technical standard was proposed to solve the human and material resource consumption caused by data analysis and repeated entry due to different businesses and platforms between various systems.

[0003] At present, software vendors supporting the GIM standard generally have problems such as insufficient GIM model universal standardization migration capabilities, insufficient model optimization and warehousing capabilities, etc., especially in the modeling of relay protection cabinets, which often only model the basic appearance structure and basic properties of the cabinets and devices, and the modeling of the internal devices and accessories of the cabinets is not refined enough, and the complex and rich specific characteristics of the relay protection cabinets are not reflected. At the same time, in the modeling process of the relay protection cabinets, there is a lot of repetitive work, and no consideration is given to the use of efficient combination and reuse methods, resulting in low modeling efficiency.

[0004] Therefore, it is urgent to study a GIM three-dimensional refined rapid modeling method for substation relay protection cabinets. The core of this method is to re-edit and define the geometric fineness files and attribute fineness files at the equipment level and component level, and realize the three-dimensional refined rapid modeling of relay protection devices based on the decomposition and reconstruction of GIM files. Summary of the invention

[0005] The purpose of the present invention is to provide a three-dimensional refined rapid modeling method for relay protection cabinets based on the GIM format to solve the problems of insufficient refinement of the existing three-dimensional model of substation relay protection cabinets, rough models, and low modeling efficiency. By decomposing and reconstructing based on GIM files, three-dimensional refined rapid modeling of relay protection devices can be achieved.

[0006] In order to achieve the above object, the solution of the present invention is:

[0007] A three-dimensional refined rapid modeling method for relay protection cabinet based on GIM format, including:

[0008] Relay protection cabinets are divided into five levels: the whole station level, the system level, the equipment level, the component level, and the software level.

[0009] Mining the geometric details and attribute details at the device level and component level;

[0010] Deconstructing the GIM model file of the relay protection panel cabinet, and obtaining a new panel cabinet GIM file based on the mining and reconstruction;

[0011] The new screen cabinet GIM file is imported into the model library for calling during 3D modeling.

[0012] Among them, the relay protection cabinet is divided into five levels according to the whole station level, system level, equipment level, component level and software level, including:

[0013] The whole station level includes the power plant or power station where the relay protection panel cabinet is located, the system level includes the interval system corresponding to the relay protection panel cabinet, the equipment level includes the relay protection panel cabinet, the component level includes the protection device or measurement and control device contained in the relay protection panel cabinet, and the software level includes the software information of the device contained in the relay protection panel cabinet.

[0014] The mining of the geometric details and attribute details of the device level and component level includes:

[0015] The characteristics of device-level geometry and attribute granularity are studied, and the attribute file fam and geometry model mod of the device-level GIM model are split and redefined; the characteristics of component-level geometry and attribute granularity are studied, and the attribute file fam and geometry model mod of the component-level GIM model are split and redefined.

[0016] The GIM model file of the relay protection panel cabinet is deconstructed, and a new panel cabinet GIM file is obtained based on the mining and reconstruction, including:

[0017] Deconstruct the GIM model file of the relay protection panel cabinet, split the GIM model file of the panel cabinet into component-level GIM, and deconstruct the attribute file fam and geometric model mod from the component-level GIM file. Based on the re-editing and definition of the attribute file fam and geometric model mod, reconstruct the improved component-level attribute file fam and geometric model mod into a new panel cabinet GIM file.

[0018] Among them, the GIM model file of the deconstructed relay protection panel cabinet includes:

[0019] The GIM model of the relay protection cabinet is decomposed into the engineering model cbm, the physical model dev, the combined model phm, and the geometric model mod, among which the physical model dev is decomposed into the physical model file dev and the attribute file fam.

[0020] The mining of the geometric details and attribute details of the device level and component level includes:

[0021] The geometric details of the equipment level include cabinet type, size, installation opening, screen eyebrow, terminal block, copper busbar, and the attribute details include equipment name, equipment model, manufacturer, screen cabinet color, and protection level;

[0022] The component-level geometric details include overall dimensions, mounting holes, display screens, buttons, indicator lights, and backplane terminals. The attribute details include manufacturer, component model, device number, device power supply, CT ratio, software version, checksum, and interval.

[0023] The new screen cabinet GIM file is imported into the model library for calling during 3D modeling, including:

[0024] Import the new screen cabinet GIM file into the model library, and disassemble the screen cabinet GIM into component GIMs, which are also imported into the model library;

[0025] When three-dimensional modeling of a new screen cabinet is performed, the existing GIM models in the model library are identified and called.

[0026] When the new screen cabinet is 3D modeled, the existing GIM models in the model library are identified and called, including:

[0027] The component model files in the model library are called by combining and reusing.

[0028] A computer device comprises a memory, a processor, and a computer program stored in the memory and executable on the processor; when the processor executes the computer program, the steps of the above-mentioned three-dimensional refined rapid modeling method for relay protection cabinets based on the GIM format are implemented.

[0029] A computer-readable storage medium stores a computer program; when the computer program is executed by a processor, the steps of the above-mentioned three-dimensional refined rapid modeling method for relay protection cabinets based on the GIM format are implemented.

[0030] After adopting the above scheme, the present invention first refines and deconstructs the hierarchical structure of the relay protection panel cabinet to realize the hierarchical division of the relay protection panel cabinet at the whole station level, system level, equipment level, component level, and software level; then focuses on the in-depth mining of the geometric fineness and attribute fineness of the equipment level and component level to enrich the model fineness; then reshapes the three-dimensional refined model of the relay protection panel cabinet by decomposing and reconstructing the GIM file; finally, based on the reuse and combination of the model, the rapid refined modeling of the relay protection panel cabinet is realized; and then a refined GIM format three-dimensional model with clear hierarchy, rich details and high modeling efficiency is established through the above steps.

[0031] The beneficial effects achieved by the present invention are as follows: the present invention starts from the scientific and reasonable division of the hierarchical structure of the relay protection panel cabinet, and proposes the decomposition and reconstruction of the three-mode model of the relay protection panel cabinet, thereby realizing the refined and rapid modeling of the relay protection panel cabinet, and solving the problems of insufficient modeling precision, poor visibility, and poor reusability of conventional relay protection panel cabinets. It is conducive to unifying the model architecture and data interaction format, realizing data sharing throughout the life cycle of the project, supporting the panoramic digital design of the secondary system, improving the production and debugging efficiency of the secondary panel cabinet, and improving the on-site construction and debugging efficiency of the transmission and transformation project, and has considerable economic value for production, construction, and debugging.

[0035] The technical solutions and beneficial effects of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown, the present invention provides a three-dimensional refined rapid modeling method for relay protection panel cabinet based on GIM format, comprising the following steps:

[0037] 1. Refinedly deconstruct the hierarchical structure of the relay protection panel cabinet, realize the hierarchical division of the relay protection panel cabinet at the whole station level, system level, equipment level, component level, and software level, elaborate and explain each level of the relay protection panel cabinet, clarify the inclusion relationship between the five-layer structure, and explain the logical relationship between the five protection structures.

[0038] The relay protection panel cabinet does not exist independently. It is subordinate to a specific power plant or power station above and contains a number of relay protection equipment and accessories below. Therefore, it is necessary to make a clear division of the hierarchical structure of the relay protection panel cabinet: (1) The whole station level, that is, the power plant or power station where the relay protection panel cabinet is located. (2) The system level, that is, the interval system corresponding to the relay protection panel cabinet, such as the transformer unit system, line unit system, and bus unit system; (3) The equipment level, that is, the relay protection panel cabinet itself, such as the main transformer protection A panel, 220kV line protection cabinet, and 35kV bus protection cabinet; (4) The component level, that is, the protection device or measurement and control device contained in the relay protection panel cabinet, such as the main transformer A set of electrical quantity protection, main transformer non-electrical quantity protection, and line differential protection. The components also include related accessories, including circuit breakers, terminal blocks, pressure plates, buttons, transfer switches, etc.; (5) The software level, that is, the software information of the devices contained in the relay protection panel cabinet, including software version, checksum information, etc.

[0039] 2. Focus on the in-depth exploration and research of the geometric and attribute granularity of the equipment level and component level; based on the five-layer model structure of the relay protection cabinet divided in step 1, analyze that the levels that best reflect the characteristics of the cabinet are the equipment level and the component level, study the characteristics of the geometric and attribute granularity of the equipment level, split and redefine the attribute files (fam files) and geometric models (mod files) of the equipment level GIM model; study the characteristics of the geometric and attribute granularity of the component level, split and redefine the attribute files (fam files) and geometric models (mod files) of the component level GIM model.

[0040] At the equipment level, it is mainly the geometrical and attribute details of the panel cabinet itself. The geometrical details include: cabinet type, size, installation opening, panel eyebrow, terminal block, copper busbar, etc. The attribute details include: equipment name, equipment model, manufacturer, panel cabinet color, protection level, etc. The redefinition of geometrical details is achieved by re-editing the geometrical model of the equipment model (i.e. mod file), and the redefinition of attribute details is achieved by re-editing the attribute file of the equipment model (i.e. fam file); at the component level, it is mainly the geometrical and attribute details of the relay protection equipment itself. The geometrical details include: external dimensions, installation opening, display screen, button, indicator light, backplane terminal, and the attribute details include: manufacturer, component model, device number, device power supply, CT ratio, software version, check code, and belonging interval; the redefinition of geometrical details is achieved by re-editing the geometrical model of the component model (i.e. mod file), and the redefinition of attribute details is achieved by re-editing the attribute file of the component model (i.e. fam file);

[0041] 3. Realize three-dimensional refined modeling of relay protection devices based on the decomposition and reconstruction of GIM files.

[0042] Based on the five-layer structure division in step 1 and the exploration of model fineness in step 2, the GIM model file of the relay protection panel cabinet is deconstructed, the GIM model file of the panel cabinet is split into component-level GIM, and the fam file and mod file are deconstructed from the component-level GIM file. Based on the re-editing and definition of the fam file and mod file in step 2 described in claim 1, the improved component-level fam file and mod file are reconstructed into a new panel cabinet GIM file.

[0043] Cooperate Figure 2 As shown in the figure, the GIM model of the relay protection panel cabinet is first decomposed. The standard GIM model of the relay protection panel cabinet includes the engineering model cbm, the physical model dev, the combined model phm, and the geometric model mod. The physical model dev can be disassembled into the physical model file dev and the attribute file fam. Based on the in-depth mining of the geometric fineness and attribute fineness of the equipment level and the component level in step 2, the attribute file fam and the geometric model mod of the panel cabinet are decomposed into the attribute file fam and the geometric model mod of the device and accessories. Based on the refinement and enrichment of the model fineness, the physical attribute file fam and the geometric model mod of the device and accessories are optimized, redefined and edited. In the process of decomposing the GIM file of the panel cabinet, it can be decomposed into the corresponding component GIM according to the refinement requirements of the actual project, such as decomposing into the GIM of the device, terminal block, circuit breaker, optical cable terminal box, pressure plate and other components. Even if there are special requirements for the software program information of the device, a model file can be set separately for the software program, wherein the geometric model file of the software program can be set to empty, and the attribute file contains the version, checksum and other information of the software program.

[0044] Then the attribute file fam and geometric model mod of the device and accessories are reconstructed. The reconstruction process of the attribute file fam is the reconstruction process of the physical model dev. The attribute file fam of the device, terminal block, circuit breaker, optical cable terminal box, pressure plate and other components is reconstructed into the attribute file fam of the entire panel cabinet. The reconstruction process of the geometric model mod reconstructs the geometric model mod of the device, terminal block, circuit breaker, optical cable terminal box, pressure plate and other components into the geometric model mod of the entire panel cabinet, thereby forming a reconstructed GIM model of the relay protection panel cabinet.

[0045] 4. Rapid and refined modeling of relay protection cabinets is achieved based on model reuse and combination.

[0046] In the modeling process of a single screen cabinet, the built screen cabinet GIM model is imported into the model library, and the screen cabinet GIM is disassembled into component GIM, and the component GIM is also imported into the model library. When modeling a new screen cabinet in 3D, the existing GIM model in the model library can be identified and called. Specifically: the physical model (dev file) of the new screen cabinet can call the physical model (dev file) of the component level in the model library. Based on the combination and reuse method, the repeated modeling of the same component is avoided, and the new screen cabinet model is directly generated from the existing component model.

[0047] The modeling process of a single relay protection panel cabinet is not carried out in isolation. During the modeling process of each relay protection panel cabinet, the GIM model file information of the panel cabinet and its internal devices and accessories will be summarized in the model library; specifically, after the modeling of a single relay protection panel cabinet is completed, its panel cabinet model, device model, circuit breaker model, pressure plate model, terminal block model, device software information, etc. will be transferred to the GIM model library and coded.

[0048] Then, in the modeling process of the new relay protection panel cabinet, the GIM model files of the panel cabinet body, device, circuit breaker, pressure plate, terminal block and other components in the model library can be called at any time, or only the engineering model cbm, physical model dev, combination model phm, geometric model mod in the component GIM model file can be called, or even only the attribute file fam and geometric model mod can be called;

[0049] The essence of the rapid modeling method is the flexible calling of component model files, which is done by combination and reuse. For the GIM model modeling process of a new relay protection panel cabinet, the component model files can be flexibly reused. The component GIM files can be reused as a whole, or the physical model dev, geometric model mod and other files therein can be reused. Then, multiple component models can be flexibly combined. The GIM files of accessories such as devices, circuit breakers, and terminal blocks can be packaged and combined as a whole, or only some of the files can be combined, for example, only the geometric model mod files can be combined, or only the fam files in the physical model dev files can be combined.

[0050] Ultimately, by establishing a GIM database that meets the requirements of full life cycle data sharing and unified model architecture, components with the same attributes and similar geometries can be quickly called, avoiding repeated modeling processes, thereby achieving refinement of relay protection cabinets and speeding up the modeling process.

[0051] The present invention proposes a method for three-dimensional fine rapid modeling of substation relay protection cabinets. Figure 1 This is the implementation process of the present invention.

[0052] Step 1: Refine and deconstruct the hierarchical structure of the relay protection cabinet

[0053] Taking three specific relay protection cabinets as an example, the line protection measurement and control, anti-island protection cabinet and busbar protection cabinet, their hierarchical classification is shown in Table 1.

[0054] 1) The whole station level, that is, the substation where the relay protection cabinet is located, can be divided into: State Grid, Southern Grid, Huaneng, Three Gorges, Petrochemical, etc. according to users; can be divided into: substation, power plant, user station, etc. according to industry attributes; can be divided into: 110kV, 220kV, 35kV according to voltage level; can be divided into conventional AC station and converter station according to AC and DC.

[0055] Table 1

[0056]

[0057] 2) System level, that is, the system where the relay protection cabinet is located. According to the protection object, it can be divided into lines, main transformers, busbars, generators, etc., and according to the function, it can be divided into protection, measurement and control, safety and stability, etc.;

[0058] 3) Equipment level, i.e. the relay protection panel cabinet itself;

[0059] 4) Component level, i.e. the devices and accessories contained in the relay protection cabinet. The devices can be divided into protection devices, measurement and control devices, safety devices, etc. The accessories can include circuit breakers, terminals, pressure plates, transfer switches, buttons, etc.;

[0060] 5) Software level, i.e. software information of the devices contained in the relay protection panel cabinet, generally including software version, checksum, etc.;

[0061] According to the needs of actual projects, the deconstruction depth of the screen cabinet level can be adjusted. For example, the screen cabinet body can be further deconstructed into front door, rear door, metal shell, screen eyebrow, small busbar, grounding copper busbar, etc. The device body can be deconstructed into metal shell, LCD panel, input plug-in, output plug-in, analog plug-in, CPU plug-in, etc. The circuit breaker can be deconstructed into circuit breaker and circuit breaker auxiliary contacts, the transfer switch can be deconstructed into transfer switch and label printing, the pressure plate can be deconstructed into pressure plate body and pressure plate label, and the optical cable terminal box can be deconstructed into shell, connector, and optical fiber.

[0062] Step 2: refine and expand the geometric and attribute details at the device and component levels;

[0063] First, the dimension and depth of the geometric granularity and attribute granularity at the equipment level are mined, taking the busbar protection measurement and control cabinet as an example.

[0064] 1) Based on the newly mined cabinet geometry information, redefine the cabinet geometry information in the cabinet mod model file as follows:

[0065]

[0066] 2) Based on the newly mined cabinet attribute fineness information, the cabinet geometry information is redefined in the cabinet fam model file as follows:

[0067] [Design parameters]

[0068] Manufacturer = Manufacturer = NARI

[0069] Unit = Unit = Area

[0070] Cabinet Model = Cabinet Model = G31

[0071] Cabinet name = Cabinet name = 110kV busbar protection and control cabinet

[0072] Cabinet number = Cabinet number = PPC23LA-FA-GC

[0073] Rated voltage = Rated voltage = 220

[0074] PMS device ID = PMS device ID = -

[0075] Material code = Material code = Automatically generated by software

[0076] Name = Cabinet name = 110kV busbar protection and control cabinet

[0077] Type=Screen cabinet model=G31-2300*700*600

[0089] Secondly, the dimension and depth of geometric granularity and attribute granularity at the component level are explored, taking the busbar protection device as an example.

[0090] 1) Based on the re-excavated geometric fineness information of the protective device, the geometric information of the protective device is redefined in the mod model file of the protective device as follows:

[0091]

[0092]

[0093] 2) Based on the newly mined attribute granularity information of the protection device, the attribute information of the protection device is redefined in the mod model file of the protection device as follows:

[0094] [Design parameters]

[0095] Manufacturer = Manufacturer = NARI

[0096] Unit = Unit = Unit

[0097] Device Model = Device Model = PCS-923LA-FA-GC-G9

[0100] Rated voltage = Rated voltage = 220

[0110] Similarly, the geometric details and attribute details of other components in the panel cabinet, such as circuit breakers, transfer switches, buttons, pressure plates, optical cable terminal boxes and other accessories, can be further mined, and the mod files and fam files of these components can be re-edited and defined.

[0111] Step 3: Implement 3D refined modeling of the relay protection panel cabinet based on the decomposition and reconstruction of the GIM file

[0112] The GIM 3D model files of the relay protection panel cabinet, device and other accessory equipment in the cabinet include engineering model (cbm file), physical model (dev file), combination model (phm file), and geometric model (mod file). The physical model (dev file) is composed of combination model (phm file) and model attributes (fam file). Based on this, the process of panel cabinet model decomposition and reconstruction is as follows:

[0113] 1) Decomposition: Decompose the relay protection cabinet model into component models, adjust the decomposition level according to the actual needs of the project, and further decompose the component model into the level of basic model files. The focus is on the decomposition of each component model attribute (fam file) and geometric model (mod file);

[0114] 2) Refinement: Fully consider the actual situation of the specific project, such as special cabinet structure requirements, pressure plate color separation requirements, circuit breaker brand requirements, etc., and refine the model attributes (fam file) and geometric model (mod file) of each component model, as well as other basic model files.

[0115] 3) Reconstruction: Recombine the model attributes (fam file) and geometric model (mod file) of the component model after fine editing, as well as other basic model files, to complete the reverse reconstruction of the cabinet model.

[0116] Step 4: Based on data interaction and mining, as well as model reuse and combination, the rapid modeling of relay protection cabinets is realized

[0117] Cooperate Figure 3 As shown in the figure, the key to rapid modeling of relay protection cabinets lies in the establishment of a model database, as well as the reuse and combination of models.

[0118] 1) Establishment of model database: After the modeling of the relay protection panel cabinet is completed, its panel cabinet model, device model, circuit breaker model, pressure plate model, terminal block model, device software and other information will be disassembled and retained in the system. After encoding processing, a preliminary model database will be formed. By constructing a large number of panel cabinet models, the model database can be enriched and improved.

[0119] 2) Model reuse and combination: Taking the physical model (dev file) in the panel cabinet GIM model as an example, the combination and reuse process is as follows:

[0120] (a) Decompose the GIM model file of the relay protection cabinet to deconstruct the physical model (dev file) of each component in the cabinet;

[0121] (b) Search for reusable component physical models (dev files) in the model library;

[0122] (c) Identify the reusable component physical models (dev files) and directly use the original files, or modify and upgrade the source files according to the new working conditions;

[0123] (d) Combine the reusable physical models (dev files) and merge them with the newly created physical models (dev files) of other components to form the physical model (dev file) of the new panel cabinet;

[0124] (e) Integrate the physical model of the screen cabinet (dev file) into the screen cabinet GIM model file.
