Description

Technical Field

[0001] The present invention belongs to the technical field of power transmission and transformation equipment operation and maintenance, and in particular relates to a method and system for associating a visualization model of power transmission and transformation equipment with a monitoring and management model. Background Art

[0002] Construct a 3D visualization system for power transmission and transformation equipment to realize the visualization of functions such as power transmission and transformation equipment monitoring, signal analysis, and fault cause analysis and disposal. The simulation degree of the appearance of the 3D visualization model of the power transmission and transformation equipment is not only high, but also the status of data such as data expression and operation control should accurately correspond to the actual situation. The power transmission and transformation equipment monitoring and management system contains data such as equipment status monitoring, control, and equipment management; the 3D visualization system of power transmission and transformation equipment constructs a data model of power transmission and transformation equipment in a virtual reality scene, including 3D display of equipment, basic data of equipment, operating status data, and various statistical analysis and management data. The data comes from the power transmission and transformation equipment monitoring and management system, and needs to be obtained from it.

[0003] Therefore, in order to truly reflect the status of power transmission and transformation equipment, it is necessary to achieve accurate association between the three-dimensional visualization model of power transmission and transformation equipment and the equipment monitoring and management model, so that when the actual system is in operation, the three-dimensional system can quickly extract the content of related projects from other system data, and ultimately achieve the purpose of effective integration of visualization graphics and real-time data, and ensure the consistency of related data between the three-dimensional system and monitoring management systems.

[0004] The intercommunication of information is based on models, and the information content is transmitted through various data interaction services. Existing systems such as power transmission and transformation equipment monitoring and management involve many manufacturers, with different development times, and use equipment models for different application scenarios. There is no unified standard for model definition, and there are great differences in data classification, content and expression. Among them, some data, such as equipment management data, use different "fields" to express various data items. Due to the inconsistent "field" definitions of various systems, the model comparison work is complicated; the storage of monitoring data is mostly based on point table models, and it is impossible to obtain accurate data reference content from the interactive data during information interaction. The association relationship between models must be constructed before data interaction to achieve data correspondence in the actual system. The existing model association methods are all for different systems, manually comparing data "fields" or data "point tables" one by one, and establishing associations with the data content of the actual plant, station, interval, and equipment according to the field and point number reference content, and then extracting key information such as data items, types, and data content from them. Not only does it increase the engineering workload, but it is also not conducive to the expansion and application of the system and the query and maintenance of later information. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the present invention provides a method and system for associating a power transmission and transformation equipment visualization model with a monitoring and management model, which can realize the rapid association of the power transmission and transformation equipment monitoring and management model with the power transmission and transformation equipment visualization model.

[0028] In order to further describe the technical features and effects of the present invention, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0029] like Figure 1-4 As shown, a method for associating a visualization model of power transmission and transformation equipment with a monitoring and management model includes the following parts:

[0030] 1. Constructing a knowledge graph conceptual model for power transmission and transformation equipment monitoring management and equipment 3D display with physical entities as the core

[0031] The monitoring management of power transmission and transformation equipment and the three-dimensional display data of equipment are divided according to content, which may involve equipment management, operating status, control and operation, diagnosis and disposal, etc.

[0032] In power transmission and transformation equipment monitoring and management systems, monitoring information is usually received, stored and released in units of protection, control, monitoring and other terminal equipment. A single power transmission and transformation equipment may correspond to multiple sets of terminal equipment, and a terminal equipment may also correspond to multiple sets of power transmission and transformation equipment at the same time. Equipment management is usually carried out in units of a single set of power transmission and transformation equipment.

[0033] In the three-dimensional display operation part, the display of data information is based on the physical entity of virtual power transmission and transformation equipment, usually a single set of power transmission and transformation equipment. Therefore, the present invention constructs a knowledge graph based on the physical entity of power transmission and transformation equipment.

[0034] The knowledge graph construction resources come from the power transmission and transformation equipment monitoring and management data and the power transmission and transformation equipment three-dimensional system display data. The structure of the knowledge graph can be expressed as a triple<h,r,t> express:

[0035] Among them, h and t represent entities, representing the head entity and the tail entity respectively, and r represents the relationship.

[0036] According to the conceptual model of the knowledge graph, the conceptual model of the knowledge graph can be constructed through the following steps:

[0037] Collect ontology and ontology relationship corpus. The corpus content includes: power transmission and transformation equipment components, power transmission and transformation equipment monitoring terminals, real-time monitoring data content, real-time control items, equipment diagnosis, equipment abnormality disposal measures, etc.

[0038] Filter the keywords of ontology and ontology relationship. Due to the diversity of language expression, it is difficult to match the same knowledge. Through keywords, data types, data instances, etc., confirm the vocabulary of ontology and ontology relationship, realize ontology alignment, and build a synonym table of vocabulary.

[0039] Organize the ontology and ontology relationship of the knowledge graph (organize the aforementioned ontology and ontology relationship keywords according to their relationships to build a conceptual model) and establish an overall conceptual model of the knowledge graph for a single set of power transmission and transformation equipment.

[0040] The simplified design of the concept layer of the knowledge graph of power transmission and transformation equipment is as follows: Figure 1As shown in the figure. The knowledge graph can be divided into two parts: the device level and the component level. The entire graph is based on physical devices. The functional module entities such as monitoring, control, and management all realize the association between physical devices and device components according to the data flow direction. Each ontology is connected through the ontology relationship. The solid line part is the association path between physical device ontologies, and the dotted line part is the association path between physical devices and functional modules.

[0041] Figure 1 The arrow in the middle indicates the source direction or control direction of the data. The meanings of each relationship are:

[0042] Composition: indicates that the physical device ontology of "device" is composed of the components expressed by the "component" ontology, pointing to the composed device;

[0043] Physical object: indicates that the ontological data such as "operation monitoring", "diagnosis", and "disposal" are information mapped to actual physical equipment or components. According to the data flow direction, it points from the physical ontology to the monitoring quantity, or from the diagnosis and disposal ontology to the physical ontology;

[0044] Diagnosis and treatment: The "Diagnosis" ontology points to the "Treatment" ontology. The "Diagnosis" ontology can include multiple diagnosis items and diagnosis results. The "Diagnosis and treatment" relationship refers to the association of each diagnosis result with the treatment operation in the "Treatment" ontology;

[0045] Control: "Measurement and control equipment" and "protection equipment" point to the physical equipment or component body, indicating that the "measurement and control equipment" and "protection equipment" implement operational control over the actual equipment. For example, when the transformer is overloaded, the "protection equipment" starts to control the "cooler" of the "transformer";

[0046] Data collection: "Measurement and control equipment", "protection equipment" and "monitoring equipment" collect data from the equipment and its components, starting from the "equipment" and "component" entities and pointing to the "measurement and control equipment", "protection equipment" and "monitoring equipment" entities;

[0047] Data source: The data of the "operation monitoring" entity comes from the "protection equipment", "measurement and control equipment" and "monitoring equipment"; the data of the entity that implements "diagnosis" of the equipment status also comes from the "protection equipment", "measurement and control equipment" and "monitoring equipment".

[0048] 2. Supplement monitoring management knowledge and 3D display knowledge graph data based on the concept model of power transmission and transformation equipment monitoring management and equipment 3D display knowledge graph

[0049] The monitoring management and 3D visualization data of power transmission and transformation equipment can be expressed as: <attribute name keyword, data type, data value range> structure.

[0050] The attribute name keyword is one or more keywords decomposed from the data attribute name, the data type is the computer expression of the data, and the data value range is the actual value set that the data may have.

[0051] Use the knowledge graph modeling tool to construct specific power transmission and transformation equipment monitoring knowledge and three-dimensional display knowledge graph instances. According to the constructed knowledge graph conceptual model, fill in the corresponding positions of the model with the actual three-dimensional visualization model attribute name keywords and the attribute name keywords, data types and data value ranges of the power transmission and transformation monitoring and management system according to the matching rules. The matching rules can be divided into data source matching, power transmission and transformation equipment component matching, operation monitoring data content matching, control operation item matching, equipment diagnosis matching, and disposal measure matching according to the ontology classification. By comparing the vocabulary vector of the attribute name keyword with the synonym list in the process of conceptual model construction, the association between the actual system model and the conceptual model is realized, the knowledge graph data is supplemented, and the knowledge graph is linked with the actual power transmission and transformation equipment monitoring and management system and the three-dimensional system. Figure 2 shown.

[0052] Taking the oil-immersed transformer as an example, the steps for using transformer monitoring knowledge and three-dimensional knowledge graph to construct the association relationship between the three-dimensional system and the monitoring management system are as follows.

[0053] 1) Construct transformer monitoring knowledge and 3D knowledge graph ontology

[0054] Typical data of the transformer monitoring and management information system are shown in Table 1:

[0055] Table 1 Typical data table of transformer monitoring and management system

[0056]

[0057] The transformer three-dimensional system display content is shown in Table 2:

[0058] Table 2 Typical data of transformer three-dimensional system

[0059]

[0060]

[0061] As can be seen from Table 2, the basic data displayed by the three-dimensional system comes from monitoring information. During the display process, it needs to be associated with the equipment structure components and support the display of data analysis and expansion applications.

[0062] According to the contents in the above table, the transformer knowledge graph ontology is constructed as follows: Figure 3 The transformer knowledge graph is based on equipment components and includes all basic data and extended application data of the three-dimensional system and monitoring management system.

[0063] The display and application of the three-dimensional system are associated with components, and the ontologies are connected through ontology relationships.

[0064] 2) Configure the association relationship of the knowledge graph ontology of power transmission and transformation equipment

[0065] The three-dimensional visualization model of the transformer is interconnected with the monitoring and management model. For components, only the parts related to the monitoring and management content are associated. The example transformer knowledge graph ontology association builds matching rules according to components, monitoring equipment, operation monitoring, fault diagnosis, defect handling, etc.

[0066] Taking the operation monitoring and abnormal diagnosis and processing of transformer windings as an example, the relevant knowledge graph is constructed as follows: Figure 4 shown.

[0067] Among the parts of the transformer, the parts related to the winding are all in Figure 4 The equipment management module manages all kinds of information of the transformer in a unified manner. The protection device and the measurement and control device collect voltage and current from the windings. The main protection collects the state of the pressure relay action contacts from the pressure relay. The state monitoring device collects partial discharge, pressure, temperature and other monitoring information from the equipment components. The data of the protection and measurement and control equipment is used to realize fault diagnosis, and the data of the monitoring equipment is used to realize equipment status evaluation. The defect management function gives specific defect disposal measures according to the fault diagnosis and status evaluation results, and disposes the transformer equipment or components.

[0068] The transformer ontology can be divided into the following categories according to the direction of data flow and function realization, including: composition, physical object, diagnosis and treatment, control, data collection and data source, etc. Figure 4 shown.

[0069] 3) Supplement transformer monitoring management knowledge and 3D display knowledge graph data

[0070] According to the constructed transformer knowledge graph conceptual model, the actual three-dimensional visualization model keywords and the keywords, data types and instances of the power transmission and transformation monitoring and management systems are filled in the corresponding positions of the model to realize the link between the knowledge graph and the actual power transmission and transformation equipment monitoring and management systems and three-dimensional systems.

[0071] The example table of the association between transformer monitoring management data and knowledge graph ontology is as follows:

[0072]

[0073]

[0074] Through the knowledge graph modeling method proposed in the present invention, an association relationship is established between the transformer monitoring and management data items and the knowledge graph ontology, thereby realizing data association between different power transmission and transformation monitoring systems and three-dimensional visualization systems based on the knowledge graph.

[0075] The relationship between the transformer knowledge ontology and other ontologies can also be classified according to the knowledge graph ontology relationship proposed in the present invention to construct the association relationship between ontologies.
