[0042] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0043] Example 1:
[0044] like Figure 1 As shown, this embodiment provides a configuration-based modeling method based on power grid device characteristics, including the following steps:
[0045] S1: Obtain the basic appearance data, layout data, static parameters and dynamic parameters of the power transmission and transformation facilities, and build a digital twin configuration unit model of the power transmission and transformation facilities.
[0046] Specifically, the physical environment and primary and secondary equipment in the substation are first scanned using laser point cloud equipment to obtain a substation cloud model. Then, based on the substation cloud model, the equipment location layout data, appearance structure data, and mapping material data in the substation are obtained, and a point cloud file is generated.
[0047] At this point, combined with the preset coordinate system, the point cloud file is imported into the file processing tool and the point cloud file in LAS format is output; finally, through the refined modeling tool, with reference to the equipment drawings, point cloud files and image data of the power transmission and transformation facilities, the primary equipment facilities and secondary equipment in the substation are disassembled and modeled at the component level to generate a digital twin configuration unit model of the power transmission and transformation facilities.
[0048] It can be seen that step S1, through the sorting and research of power transmission and transformation equipment and facilities, combined with the equipment operation mechanism and combination logic, splits and abstracts the equipment according to certain rules, and constructs a model configuration resource with full adaptability and comprehensiveness from the perspective of the appearance, action, logic, and mechanism integration of the equipment and facilities.
[0049] As an example, the specific process of this step is as follows:
[0050] Laser point cloud equipment is used to conduct detailed scanning of the physical environment and primary and secondary equipment within the substation to obtain a complete, accurate, and clear substation site cloud model. This is used to obtain the actual and detailed equipment location layout, appearance structure, and texture material reference data within the substation, which is used to better guide the development of detailed modeling. During the scanning process, the number of scanning points and the acquisition time should be controlled to minimize the operation time while ensuring accuracy, thereby improving overall implementation efficiency.
[0051] Determine the output of two coordinate systems: the CSGS2000 geodetic Gaussian coordinate system and the 84-degree longitude and latitude coordinate system, to support subsequent corresponding business development. Finally, import the scanned point cloud file into the tool for comprehensive processing and finally output it into LAS format files for later import into 3D tools for secondary development. At the same time, according to actual business needs, choose color point cloud scanning or black and white point cloud scanning;
[0052] Through refined modeling tools, referring to equipment drawings, point cloud files, and image data obtained from on-site collection, component-level disassembly modeling is performed on some primary equipment facilities and secondary equipment in the substation. The disassembly logic complies with the actual composition logic, action logic, and energized state logic of the equipment, thereby achieving in-depth support for the business. According to the component disassembly logic, combined with the corresponding data structure, business support for subsequent parameterized calls is realized.
[0053] In addition, it should be noted that in step S1, it is also necessary to study the configuration modeling of typical circuits of measurement, control, protection, and communication secondary equipment based on the modeling of primary equipment such as transmission lines, transformers, switches, knife switches, GIS, and switchgear. Combined with drawings and electrical signal paths, it supports the expansion of relay protection and information communication related businesses, realizes the full coverage of substation digital twins, and forms differentiated requirements for the construction level and accuracy of various equipment models that meet different actual production needs, and provides targeted modeling methods for different modeling requirements of different objects.
[0054] S2: Obtain information on distribution network transmission lines and substations, and use the equipment model resource library to build a digital twin model of the transmission corridor.
[0055] Specifically, drones are used to perform point cloud scanning of distribution network transmission lines to obtain transmission line information. Pole towers, conductors, insulators, and jumpers are then modeled based on the structural drawings of the line equipment and stored in the equipment model library. Furthermore, oblique photography and structured light scanning are used to obtain information about typical distribution lines and transmission equipment. Based on the structural drawings of the transmission equipment, models of typical distribution lines, substation terminals, circuit breakers, FTUs, and DTUs are then modeled and stored in the equipment model library. Finally, the multi-source modeling data is fused and overlaid, combining the equipment model library, the structural drawings of the line equipment, and the transmission equipment to construct a digital twin model of the transmission corridor.
[0056] It can be seen that step S2 uses rapid modeling technology, combined with drawing information and equipment model resource library, to try to study the fusion and superposition of multi-source modeling data, so as to quickly and accurately build a real-time on-site transmission and distribution corridor model scene.
[0057] As an example, step S2 includes:
[0058] Select the transmission and distribution lines and adopt drone point cloud scanning to build models, or select a typical line scene and manually model the towers, conductors, insulators, and jumpers according to the structural drawings to clearly express the electrical connection relationship of the lines. Through oblique photography, structured light scanning and structural drawings, model typical distribution lines, substation terminals, circuit breakers, FTUs, and DTU equipment to achieve full coverage of the transmission, transformation, and distribution processes of the regional power grid.
[0059] In addition, this method can establish relevant modeling standards for different equipment models according to different business needs, establish refined equipment models according to the modeling standards, and study the real-time display of grid structure adjustment, line load distribution, and analysis and deduction of phase-to-phase short-circuit faults on the virtual power grid built with the model.
[0060] S3: Obtain meteorological data and build real-time environmental scenarios. Use video recognition technology to obtain behavioral information of personnel at the work site, integrate environmental scenarios and behavioral information through a simulation engine, and build a digital twin model of people and the environment.
[0061] Specifically, video analysis technology combined with simulation engine algorithms leverages meteorological data obtained from third-party interfaces and combines this with data from micro-meteorological stations to construct real-time environmental scenarios. Then, a skeletal tracking algorithm based on video recognition is used to capture the actions of personnel at the worksite. By anchoring key points to the joints of a basic character model, the personnel's movements are synchronously modeled to create a digital twin of the person and environment.
[0062] It can be seen that this step uses video analysis technology combined with simulation engine algorithms, utilizes meteorological data obtained from third-party interfaces, and combines data from micro-meteorological stations to build a real-time, dynamic environmental scene. Combined with the skeleton tracking algorithm of video recognition, the behavioral actions of people on the scene are obtained. By anchoring key points on the joints of the character's basic model, synchronous modeling of the actions of people on the scene is achieved.
[0063] As an example, the specific process of this step is as follows:
[0064] Through oblique photography, structured light scanning and on-site inspections, based on sophisticated manual modeling technology, real-scene modeling of the environment surrounding power equipment is carried out. The engine is used to truly restore the natural environment, and the physical space data obtained by basic sensors and camera acquisition units are integrated with the model. This includes various visible and hidden spatial information, such as natural environmental factors such as light, temperature, humidity, wind direction, wind force, lightning, and rain, social environmental factors such as foreign objects, small animals, and outsiders, as well as other factors that affect the operation of power grid equipment. Real-time monitoring of equipment and the surrounding environment is carried out. Combined with camera video image records and access control system records, a personnel behavior model is established in the digital twin system and restored visually. Real-time supervision is carried out for violations such as improper dress, inadequate protection, and accidentally entering live intervals.
[0065] In this step, based on sophisticated manual modeling technology, the engine is used to realistically restore the power environment and micro-meteorological environment around the equipment; combined with camera video images and access control system records, a human behavior model is established in the digital twin system and automatic recognition of human behavior is achieved, which can realize the interaction between virtual people and virtual power grid facilities.

[0069] The transmission corridor model construction module 2 is configured to obtain information about the distribution network transmission lines and substations, and use the equipment model resource library to build a digital twin model of the transmission corridor.
