Description

Technical Field

[0001] This invention belongs to the field of substation configuration file technology, and proposes a method, system, device and medium for generating composite information model files suitable for substations. Background Technology

[0002] Currently, smart substations follow the IEC61850 modeling standard and use SCD (substation configuration description) as the configuration description file to achieve a complete description of the substation's topology, logical functions, and physical communication connections, effectively improving the efficiency and standardization of engineering configuration. However, with engineering applications, SCD files have revealed many drawbacks. First, SCD files contain a large amount of information, and different types of information are cross-coupled, making it difficult to define the scope of impact of modifications on the SCD file during substation renovation and expansion. Second, because different business configuration information is coupled together, different professionals cannot quickly locate the information of the business they are interested in, which is not conducive to substation maintenance management, professional management, and supervision. Third, in actual engineering configurations, SCD configurations are generally missing, resulting in a lack of primary and secondary equipment relationships and isolated modeling of secondary equipment. Fourth, with the increasing data volume of smart substations, SCD files have become too large, requiring high bandwidth during transmission. Fifth, SCD files only consider the business needs of the substation end, ignoring cross-system and cross-business interaction needs, focusing on the modeling of secondary equipment functions and their data objects, and lacking measurement data and geographical area models from the perspective of primary equipment, making it unable to directly support business system applications. This is one of the core reasons why the dispatching system cannot use the substation SCD model.

[0003] The scheduling system follows the IEC 61970 standard and uses CIM / XML or CIM / E as the configuration description file. However, since the two standard systems were designed for different systems at the beginning, and their design structures, modeling scopes, and modeling dimensions are different, CIM files cannot be completely converted to SCD files. Currently, the data association between master and substations is established through RCD point table files. The current situation of independent model files between systems brings certain interaction barriers to digital applications. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that CIM files cannot be completely converted to SCD files in the prior art, and to provide a method, system, device and medium for generating composite information model files suitable for substations.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] A method for generating composite information model files suitable for substations, comprising:

[0007] Models are classified based on equipment type, equipment entity, and relationship to obtain different types of model files;

[0008] Based on the obtained model files, supplement them with power grid topology model files and local management files to generate a model file package with multiple types of information;

[0009] The model files in the model file package are classified and compressed at multiple levels to obtain a composite substation information model file.

[0010] A further improvement of the present invention is that:

[0011] Furthermore, the model is classified based on the device type, device entity, and relationship to obtain different types of model files. Specifically, the model file content is used to determine whether there is a corresponding device type and device entity. If so, the model file is moved to the target folder corresponding to the device type and device entity. If not, a target folder associated with the content of the model file is created, and files of the same type are moved to the created target folder.

[0012] Furthermore, the equipment entities include: substations, power grids, and dispatch centers; the relationship is that the substations supply power to the power grid under the dispatch of the dispatch center.

[0013] Furthermore, based on the obtained model files, a power grid topology model file and local management files are added to generate a model file package with multiple types of information. Specifically, the power grid topology model file and local management files are set in target folders corresponding to the equipment type and equipment entity, respectively, and the target folders are set in the same file package.

[0014] Furthermore, the model files in the model file package are classified and compressed at multiple levels to obtain a composite substation information model file. Specifically, the model files are classified based on their attribute information, which includes first-level attribute information and second-level attribute information. The first-level attribute information has a higher priority than the second-level attribute information. The first-level attribute information is the name information corresponding to the equipment type and equipment entity. The second-level attribute information is the type of the model file.

[0015] Furthermore, the model files are classified based on their attribute information, including: determining the first-level classification of the model files based on the first-level attribute information; determining the second-level classification of the model files based on the first-level classification based on the second-level attribute information; and using the second-level classification as the final classification.

[0016] A system for generating composite information model files suitable for substations, comprising:

[0017] The classification module classifies models based on device type, device entity, and association relationships to obtain different types of model files.

[0018] The supplementary module supplements the obtained model file with a power grid topology model file and local management files, generating a model file package with multiple types of information.

[0019] The storage module performs multi-level classification and compression storage on the model files of the model file package to obtain a composite substation information model file.

[0020] A terminal device includes a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to perform the steps of the method described above.

[0021] A computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method described above.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This invention classifies models by equipment type, equipment entity, and relationships to obtain different types of model files. Based on these model files, it supplements them with power grid topology model files and local management files, generating a multi-type information model file package. The model files in the package are then subjected to multi-level classification, compression, and storage to obtain a composite substation information model file. This invention classifies files according to equipment and data type, covering all data information related to substation production, operation, and asset management. While the file data volume is greater than previous information model files, the file size is smaller, reducing bandwidth consumption during online transmission.

[0024] Furthermore, the composite substation information model file proposed in this invention includes a model entry file, a model index file, a power grid topology model file, a primary equipment model file, a secondary equipment model file, an auxiliary equipment model file, a communication model file, a topology model file, and a spatial area model file. Through the logical relationship between these files, the problem of cross-system interaction caused by the use of different model files by the master and substations can be effectively solved, enabling source-end maintenance and global sharing of model files.

[0025] Furthermore, the composite substation information model file proposed in this invention contains detailed main and auxiliary equipment ledger information, asset management data, operation control data, equipment correlation, power grid topology information and other types of data. Its application scope is not limited to substations, and it also supports the export of SCD files to meet the compatibility of existing systems.

[0026] Furthermore, this invention uses global IDs in model index files to associate different types of models, ensuring data uniqueness. The files uniformly record the global IDs of equipment at the substation level, and the association between the global IDs and dispatch numbers and physical IDs, thus minimizing the number of model files affected when parameters are modified.

[0027] Furthermore, this invention relates to a substation primary equipment model file format, which defines and standardizes the primary equipment type, sub-equipment and components, hierarchical structure, equipment parameters, functional measurement points, etc., according to the power grid operation logic, equipment physical structure, correlation relationship and status.

[0028] Furthermore, this invention proposes a file format that completely decouples entity-relationship information. Primary, secondary, topological, and communication model files are separated and stored independently, and file objects do not affect each other. While ensuring forward compatibility, this invention solves the problem of decoupling and local isolation of highly coupled model data within a defined scope.

[0029] Furthermore, this invention proposes to use a composite compressed package as the file storage format, presenting the compressed package externally. The internal file organization adopts a multi-level classification organization mode. First, the files are classified according to their source system and function, including management, substation, and power grid categories. Then, the content and format of each category of lower-level files are defined in detail. The file data volume is larger than that of previous information model files, but the file size is smaller, reducing the bandwidth consumption during online transmission. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings:

[0042] See Figure 1 This invention discloses a method for generating composite information model files suitable for substations, comprising:

[0043] S101, classify the models based on equipment type, equipment entity, and relationship to obtain different types of model files.

[0044] Based on the content of the model file, determine whether a corresponding device type and device entity exist. If so, move the model file to the target folder corresponding to the device type and device entity. If not, create a target folder associated with the content of the model file and move similar files to the created target folder. Device entities include: substations, power grids, and dispatch centers; the association is that the substation supplies power to the power grid under the dispatch of the dispatch center.

[0045] S102, based on the obtained model file, supplement the power grid topology model file and local management class file to generate a model file package with multiple types of information.

[0046] Set the power grid topology model file and local management class file in the target folder corresponding to the equipment type and equipment entity, respectively, and set the target folder in the same file package.

[0047] S103, perform multi-level classification and compression storage of the model files in the model file package to obtain the composite substation information model file.

[0048] The model files are hierarchically classified based on their attribute information, which includes first-level attribute information and second-level attribute information. The first-level attribute information has a higher priority than the second-level attribute information. The first-level attribute information is the name information corresponding to the device type and device entity. The second-level attribute information is the type of the model file.

[0049] The model files are classified based on their attribute information, including: determining the first-level classification of the model files based on the first-level attribute information; determining the second-level classification of the model files based on the first-level classification based on the second-level attribute information; and using the second-level classification as the final classification.

[0050] See Figure 2 This invention discloses a system for generating composite information model files suitable for substations, comprising:

[0051] The classification module classifies models based on device type, device entity, and association relationships to obtain different types of model files.

[0052] The supplementary module supplements the obtained model file with a power grid topology model file and local management files, generating a model file package with multiple types of information.

[0053] The storage module performs multi-level classification and compression storage on the model files of the model file package to obtain a composite substation information model file.

[0054] Example:

[0055] This invention proposes a composite information model file suitable for substations. The model file is designed from the perspective of multiple business system application requirements, employing a file organization mode that combines multiple file types in a single compressed package. Externally, it presents only a single compressed file, while internally it uses a two-level classification storage method to achieve a centralized representation of multi-dimensional and multi-type data. Specifically:

[0056] The new model files adopt a multi-level, categorized storage integration approach. The first-level files consist of management, power grid, and substation files. The management file includes directory management and equipment index description files; the power grid file includes inter-station communication topology information files; and the substation file includes files describing substation configuration information (see appendix). Figure 3 .

[0057] The next level of the management category includes model entry files and model index files; the next level of the power grid category includes power grid topology model files; and the next level of the substation category includes primary equipment model files, secondary equipment model files, auxiliary equipment model files, communication model files, topology model files, and spatial area model files, etc.

[0058] The generation and maintenance of the new model files involve multiple systems. Management files and substation files are mainly generated at the substation level, while the power grid topology model file is provided by the dispatching system to complete the splicing of substation topology model files. The number of each type of file is shown in Table 1.

[0059] Table 1: Number of files (model files, all per substation)

[0060]

[0061] The method for generating a composite substation information model file that replaces the SCD file covers all the contents of the SCD file and adds some additional files. It is backward compatible with the SCD file and can be converted into file formats such as SCD, CID, and CCD to ensure compatibility with existing systems.

[0062] 1. Model entry file

[0063] The composite substation information model file contains multiple types of files, which are ultimately stored in a compressed package. The model entry file essentially records the storage location of each file in the compressed package, reflecting the role of the file directory to facilitate file retrieval and location.

[0064] (1) The model entry file contains seven parts: description of primary equipment model file, description of secondary equipment model file, description of auxiliary equipment model file, description of topology model file, description of communication model file, description of geographical area model file, and description of model index file;

[0065] (2) The file description describes the name, path and format of each model file. Taking a certain bay switch as an example, the model file name is: Changjia 25B line bay 25B switch; the path is: "\Equipment\220kV\Changjia 25B line bay\", and the file format is "25B switch.pid";

[0066] (3) The model entry file name format is power grid.substation_name_dir.xml;

[0067] (4) The file content consists of two parts: file version information and model file information. The model version information is described in the Header element, which describes the file name and file path according to file type, including associated files, primary equipment model files, secondary and auxiliary equipment model files, topology model files, communication model files and spatial region model files.

[0068] (5) Model version information is described by the Header element, which contains three attributes: id, version, and revision. id indicates the file type, version indicates the current file version number, and revision indicates the previous version number. The specific format is as follows:

[0069] <header id＝"dir"version＝"1.1"revision＝"1.0">< / header>

[0070] The Header element can contain a child element named History. History describes the version history of the model file. Each history record is described by the Hitem child element, as shown below:

[0071] <header id＝"dir"version＝"1.1"revision＝"1.0">

[0072] <history>

[0073] <Hitem version="1.0"when="2023-03-04 10:59:27"who=""what=""why="" / >

[0074] < / history>

[0075] < / header>

[0076] The `version` attribute is the historical version number, the `when` attribute describes the generation time of the historical version, and the `who`, `what`, and `why` attributes represent the creator of the version, the version content, and the reason for the modification.

[0077] (6) The model file information is described by different file type elements, including INDEX_MF, TOPOLOG_MF, Equipment_MF, IED_MF, LOCATION_MF, COMM_MF, etc. The element has two attributes, namely type and desc, wherein type represents the file type, and desc represents the Chinese description. The specific form is as follows:

[0078] <INDEX_MF type="FILE"desc="Grand Unification Pilot Station Unified Model Association File">

[0079] <… / >

[0080] < / INDEX_MF>

[0081] <Equipment_MF type="DIRECTORY"desc="Grand Unification Pilot Station Primary Equipment Model File">

[0082] <… / >

[0083] < / Equipment_MF>

[0084] (7) The file type element includes the detailed content of each file, that is the File element, which includes attributes such as directory, file, and desc, wherein directory represents the relative directory of the file, file represents the name of the model file, and desc represents the Chinese description, etc. The specific form is as follows:

[0085] <INDEX_MF type="FILE"desc="Grand Unification Pilot Station Unified Model Index File">

[0086] <Filedirectory=""file="North China Power Grid_Shandong_Jinan_Pingyin County_Industrial Park_Grand Unification Pilot Station.idx"desc="" / >

[0087] < / INDEX_MF>

[0088] <Equipment_MF type="DIRECTORY"desc="Grand Unification Pilot Station Primary Equipment Model File">

[0089] <Filedirectory="\Equipment\220kV\204 Switch Bay\"file="204 Switch.pid"desc="204 Switch Bay 204 Switch" / >

[0090] <File… / >

[0091] < / Equipment_MF>

[0092] 2. Model index file

[0093] Every container, device, and data at any level of the power grid should have a unique identifier. This unique identifier is represented by a global ID, which cannot be modified during the device's lifecycle once generated.

[0094] (1) The model index file is used to store the global ID of all devices throughout the model file and the relationship between it and the asset management physical ID and scheduling number;

[0095] (2) By establishing the association between global ID and physical ID, the relationship between substation, asset management, and dispatching system is reflected;

[0096] (3) The document content records the relationship between the primary and secondary equipment of the substation and the dispatching system. This relationship is reflected by the association between the global ID and the dispatching number. The relationship with the PMS system is reflected by the association between the global ID and the physical ID. In addition, it also includes attributes such as the name of the primary / secondary equipment and Chinese description. Through these relationships and the name attributes of the primary and secondary equipment models, the primary / secondary equipment models, communication models, and regional models in the unified model can also be linked together.

[0097] (4) The purpose of the file is to centralize the model's immutable (global ID) and variable (index name, scheduling number, physical ID, etc.) attributes here, thereby avoiding frequent and excessive modifications to the model file.

[0098] (5) The file format of the model index file is: power grid.substation name_idx.xml.

[0099] (6) The file content consists of two parts: file version information and model file information. The model version information is described in the Header element, which describes the global ID, Chinese description, scheduling number and physical ID according to the device type.

[0100] (7) The model version information is described by the Header element, which contains three attributes: id, version, and revision. id indicates the file type, version indicates the current file version number, and revision indicates the previous version number. Where id is idx, the rest is consistent with the format of the model entry file.

[0101] (8) The model file information is described by elements of different file types, including elements such as VoltageLevel, Bay, Equipment and IED. Container elements such as voltage level and bay only include two attributes, id and desc; equipment elements include elements such as id, desc, code and uccd, wherein id represents the global ID of the container, desc represents Chinese description, code represents dispatching number, and uccd represents physical object number. The specific form is as follows:

[0102] <VoltageLevel id="Vol220"sDesc="220kV voltage level" / >

[0103] <Bay id="Vol220.Q1"sDesc="204 breaker bay" / >

[0104] <ConductingEquipment id="Vol220.Q1.QA1"sDesc="204 breaker bay 204 breaker"code="220204"uccd=""uccdA="0100100000000020001"uccB="0100100000000020002"uccdC="0100100000000020003" / >

[0106]

[0107]

[0108] 3. Primary equipment model file

[0109] The primary equipment model shall completely describe two parts of information: physical composition information and logical function of the equipment. The physical composition describes the components forming the equipment, and the logical function part describes the main functions of the equipment and corresponding data objects.

[0110] (1) The file name format of the primary equipment model file is: primary equipment name_pid.xml.

[0111] (2) The file content consists of two major parts: file version information and device capability description. Information related to the primary equipment model version is described under the Header element. The device capability description includes four parts: general ledger, equipment parameters, equipment components, and data objects. An entity class node (e.g., Power Transformer) describes the general ledger parameters of primary equipment, the SubEquipment element describes the physical components of the equipment, and the Measurement element describes the association between primary equipment data objects and secondary equipment.

[0112] (3) The model version information is described by the Header element, which contains three attributes: id, version, and revision. id indicates the file type, version indicates the current file version number, and revision indicates the previous version number, where id is pid, and the rest of the content is consistent with the model entry file format;

[0113] (4) The general ledger of primary equipment mainly describes the common ledger attributes of primary equipment, which are respectively described by entity object elements in Schedule 2, including Power Transformer, Breaker, Bus, etc. The element has attributes of name, desc, id, and type. name indicates the English naming of the primary equipment, which shall be unique throughout the substation, desc indicates the Chinese description, id indicates the global ID corresponding to the equipment, and type indicates the type of the primary equipment. The specific form is shown as follows:

[0114] An example of a transformer object is as follows:

[0115] <PowerTransformer name="PTR1"desc="#1 Transformer"id="Vol220.Q3.PTR1"type="PTR"templateVer="1.1" / >

[0116] An example of a breaker object is as follows:

[0119]

[0120]

[0121] (4) The nameplate parameters of primary equipment are described by the Parameter element, including the manufacturer, manufacturing country, key equipment parameters and other contents, wherein the key parameter part can be specifically represented according to different types of equipment. Taking a transformer as an example, the specific form is as follows:

[0122] <parameter>

[0123] <manufacturer> Manufacturer< / manufacturer>

[0124] <madein> Manufacturing country< / madein>

[0125] <region> Main variable area ID< / region>

[0126] <noloadcurrent> No-load current value< / noloadcurrent>

[0127] <noloadloss> No-load loss value< / noloadloss>

[0128] < / parameter>

[0129] (5) The component composition of the primary equipment body is described by the SubEquipment element, and the split-phase body of the primary equipment is described by the Body element corresponding to the entity class. The Body element contains five attributes: id, type, desc, uccd, and phase. The attribute id describes the global ID of the component, which is named in the idx file of the unified model; the attribute type is used to describe the component type; the attribute desc is the Chinese description of the component; the attribute uccd represents the physical object number; phase represents the phase, including enumeration items such as A, B, C, N, and ABC. The specific form is as follows:

[0130] An example of a split-phase transformer object is as follows:

[0131] <SubEquipment desc="Physical body component">

[0132] <PowerTransformerBody id="Vol500.Q3.PTR1.PTR1_A"desc="1#_Phase A_Transformer"Uccd=""phase="A">

[0151] (6) The primary equipment data object is described by the Measurement element, and includes attributes such as name, equipmentId, inst, iedId, and reference. name represents the name of the data object, equipmentId represents the association between the data object and the primary equipment, inst represents the instance number, iedId represents the acquisition relationship with the secondary equipment, and reference represents the Reference in the cid model of the corresponding secondary equipment of the data object.

[0152] The high-voltage line voltage of the No. 1 main transformer winding is shown as an example below:

[0157] 4. Secondary equipment model files

[0158] The secondary equipment model should include two parts: physical composition and logical function.
