Description

Technical Field

[0001] The present invention relates to the field of three-dimensional display technology, and in particular to a Unity-based three-dimensional display method for a substation secondary optical circuit and associated devices. Background Art

[0002] Substations are important power facilities, primarily responsible for transforming voltage, receiving and distributing electrical energy, controlling the flow of electricity, and adjusting voltage within the power system. Various faults may occur during the actual operation of substations. Therefore, intuitive and convenient 3D visualization has made a significant contribution to improving substation quality management and work efficiency, and has become an unstoppable trend.

[0003] The patent documents "A method and system for establishing virtual-real link mapping relationships in an intelligent substation" and "Visualization system and visualization method for optical fiber loops in intelligent substations" only show the connection status of the secondary loop and optical fiber connection in the substation in a two-dimensional plane form. The patent documents "A three-dimensional panoramic status monitoring method and system for substations based on VR" and "A three-dimensional panoramic monitoring system and method for substations based on digital twins" introduce a method for displaying a panoramic three-dimensional substation, but do not involve a method for displaying the secondary optical loop of the substation.

[0004] Existing technology uses images and measurements to perform stereoscopic measurements and then build models. The model has poor authenticity and lacks intuitive and effective means to effectively display the operating parameters and status parameter information of the substation. As a result, the substation cannot be truly and reliably monitored, resulting in low quality management and work efficiency of the substation, and inability to ensure the safe operation of the power system.

[0057] Example 1

[0058] Reference Figure 1 According to one embodiment of the present invention, a method for three-dimensionally displaying a substation secondary optical circuit and associated devices based on Unity is provided, comprising:

[0059] S1: Create a 3D model of the substation by collecting cloud data from the substation site, and create a 2D basic model by collecting basic information about the substation's secondary optical circuit.

[0060] The creation of a realistic 3D model of a substation includes:

[0061] Use drones to capture panoramic cloud data of the substation's exterior, and use panoramic cameras to capture photos of indoor panels, cabinets, and devices;

[0062] It should be noted that the device is the equipment and facilities associated with the optical circuit, including intelligent devices, switches, flanges, optical fiber distribution boxes, timing devices, and electric energy meter equipment. The intelligent device is the device defined as iedname in the digital substation SCD, including merging units, protection devices, measurement and control devices, and intelligent terminals;

[0063] Analyze the substation's external panoramic cloud data and use 3DMAX 3D modeling tools to create 3D models of the substation's external scenes and indoor panels and cabinets, as well as devices;

[0064] Furthermore, the creation of the two-dimensional basic model includes,

[0065] Collect basic information about the substation's secondary optical circuit and create a two-dimensional basic model;

[0066] The basic information of the secondary optical circuit of the substation should be explained as follows:

[0067] ① Room data: room ID, room number, room description;

[0068] ②Screen cabinet data: screen cabinet ID, screen cabinet number, screen cabinet description, the relative position of the screen cabinet in the room and the room it belongs to;

[0069] ③ Secondary optical circuit associated device data: device ID, device number, device description, device type (intelligent device, switch, optical distribution, other), the row of the panel cabinet where the device is located, device manufacturer, device model, and the panel cabinet to which the device belongs;

[0070] ④ Secondary optical circuit associated device board data: board ID, board number, board description, and the device to which the board belongs;

[0071] ⑤ Optical data transmission port data of secondary optical circuit associated device: port ID, port number, port sending and receiving direction, and the board to which the port belongs;

[0072] ⑥ Patch fiber data: patch fiber ID, starting device ID, starting board ID, starting port ID, end device ID, end board ID, end port ID;

[0073] ⑦ Optical circuit aggregate data: starting device, starting port, end device, end port, and fiber patching data JSON collection.

[0074] S2: Based on the Unity 3D platform, the data of the substation real-life 3D model and the 2D basic model are processed.

[0075] The steps for processing the data of the substation real-scene 3D model and the 2D basic model include:

[0076] ① Based on the Unity 3D platform, the indoor screen cabinets and devices are exported as prefabricated bodies, and the prefabricated bodies are set as hot update system tags to facilitate the subsequent expansion of model functions and calling of system models;

[0077] ② Bind the panel cabinet ID and device ID of the substation real-scene 3D model and the 2D basic model;

[0078] ③ Associated drawing and data information related to the real-life 3D model of the substation.

[0079] S3: Use the Unity 3D platform to create a script file to display the secondary light circuit and related devices in 3D.

[0080] The steps of three-dimensional display of the secondary light circuit and associated devices include:

[0081] ① Obtain the secondary optical circuit data set contained in the device to be viewed and parse the Json data;

[0082] ② Instantiation of the three-dimensional model of the screen cabinet: traverse the [0] to [N] jumper data set of the parsed Json data, first take [0] data, query the corresponding screen cabinet model data through the starting device ID in the jumper data model, and then query whether there is a corresponding three-dimensional model in the three-dimensional scene through the screen cabinet ID;

[0083] It should be noted that if the corresponding 3D model exists in the 3D scene, it will skip and continue to search for the 3D model corresponding to the next screen cabinet ID; if the corresponding 3D model does not exist in the 3D scene, the corresponding screen cabinet 3D model will be created through the hot update system label and named to realize the instantiation of the screen cabinet 3D model;

[0084] ③Instantiation of the device 3D model: traverse the [0] to [N] jumper data set of the parsed Json data, first take the [0] data and query the corresponding device model data through the starting device ID in the jumper data model, and then query whether there is a corresponding 3D model in the 3D scene through the device ID;

[0085] It should be noted that if the corresponding 3D model exists in the 3D scene, it will skip and continue to search for the 3D model corresponding to the next device ID; if the corresponding 3D model does not exist in the 3D scene, the corresponding device 3D model will be created through the hot update system tag and named to realize the instantiation of the device 3D model;

[0086] It should be noted that the internal space of the panel cabinet 3D model is divided into 8U. The 3D model of the intelligent device type occupies 1U, the 3D model of the switch and fiber optic distribution box type occupies 1 / 32U, and the 3D model of other types occupies 1U. The value of the device's internal space in the panel cabinet is calculated based on the row value of the panel cabinet where the device is located in the device model.

[0087] For example, if the device is in the third row of the cabinet, the value of the device in the 3D scene is (Cy-(Cx-Ux) / 2) / 8*K, where Cy represents the total height of the cabinet 3D model in the scene, Cx represents the total width of the cabinet 3D model in the scene, Ux represents the span of the device model in the scene, and K represents the data value of the cabinet row where the device is located.

[0088] ④ Parse the cabinet ID and device ID in the Json data. If the corresponding 3D model exists in the scene, it will not be recreated. Instead, it will be skipped and the 3D coordinates will be recorded.

[0089] ⑤ Create optical fiber connections between the device 3D models and the 3D models, calculate the starting coordinates of the 3D models of the devices and the jumper 3D models arranged above the 3D model of the panel cabinet, and perform the rest of the calculations in the same way as above combined with the coordinates of the device 3D models until the edge coordinates of the device are calculated;

[0090] It should be noted that the cabinet models are arranged from left to right in the order in which they appear in the Json data [0] to [N]. The leftmost cabinet is the first cabinet. First, the three-dimensional model of the device arranged as the upper device in the cabinet three-dimensional model is calculated, and the starting coordinates of the jumper three-dimensional model are calculated (U.center.x+Ux / 2, Uz / 2, U.center.y) (U.center is the center point of the model). The second coordinate is the starting coordinate translated to the right, that is, in the positive direction, a distance (U.center.x+Ux / 2, Uz / 2+M, U.center.y) (M is the width translation variable, N is the height translation variable). The rest is calculated in accordance with the above method in combination with the coordinates of the device three-dimensional model until the edge coordinates of the device are obtained.

[0091] ⑥ Use port ID and board ID to query the secondary optical circuit to number the end board and bind the mouse into the model. When the event is triggered, the data will be automatically displayed.

[0092] It should be noted that the present invention provides a Unity-based three-dimensional display method for substation secondary optical circuits and associated devices. Compared with the current two-dimensional display interface, it allows users to more intuitively and effectively see the subordinate and connection relationships between devices and panel cabinets. It also separately draws and models the label information of the circuit breaker pressure plate that is of concern to debugging and operation and maintenance, making the label information clearer and more accurate. The level of detail of some three-dimensional models is not available in other current substation three-dimensional models, achieving the effect of truly restoring the actual substation, reducing the current preparatory work of debugging and operation and maintenance personnel, and saving time and cost.

[0093] It should be noted that the present invention supplements the three-dimensional display interface of the secondary optical circuit, improves the digital function of the substation, and can effectively guide commissioning and operation and maintenance personnel to carry out troubleshooting and maintenance of key circuits, reduce the number of false trips and refusal of relay protection, reduce the mistransmission and omission of automation signals, and ensure the safe operation of the power grid and equipment;

[0094] It should be noted that the present invention associates the three-dimensional models of screen cabinets and devices with the corresponding drawing and data information, freeing debugging and operation and maintenance personnel from the heavy work of maintaining and searching drawing information, allowing them to focus on analyzing the essential causes of the problems, which can greatly improve work efficiency, enhance the reliability of communication system operation, and reduce the risk of communication system failure. It also makes the drawing and data of screen cabinets and devices fully electronic, and after structured reconstruction, they are stored in the data server, solving the pain points of paper drawing and data being easily lost, difficult to maintain, and easy to be damaged.

[0095] The second aspect of the present invention is disclosed.

[0096] Provides a Unity-based 3D display system for substation secondary optical circuits and associated devices, including:

[0097] The model creation module is used to create a real-life 3D model of the substation by collecting cloud data from the substation site, and to create a 2D basic model by collecting basic information about the substation's secondary optical circuit;

[0098] The data matching module matches the data of the substation real-life 3D model and the 2D basic model based on the Unity 3D platform;

[0099] The 3D display module is used to create script files using the Unity 3D platform to display the secondary light circuit and related devices in 3D.

[0101] Provided is a device comprising:

[0102] processor;

[0103] a memory for storing processor-executable instructions;

[0104] The processor is configured to call instructions stored in the memory to execute any one of the aforementioned methods.

[0105] The fourth aspect of the present invention is disclosed.

[0106] A computer-readable storage medium is provided, on which computer program instructions are stored, including:

[0107] When the computer program instructions are executed by a processor, any of the above methods is implemented.

[0108] The present invention may be a method, an apparatus, a system and / or a computer program product. The computer program product may include a computer-readable storage medium carrying computer-readable program instructions for executing various aspects of the present invention.

[0109] A computer-readable storage medium can be a tangible device that can hold and store instructions for use by an instruction execution device. A computer-readable storage medium can be, for example, but not limited to, an electrical storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination thereof. More specific examples (a non-exhaustive list) of computer-readable storage media include: a portable computer disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disk (DVD), a memory stick, a floppy disk, a mechanical encoding device, such as a punch card or a raised structure in a groove on which instructions are stored, and any suitable combination thereof. As used herein, a computer-readable storage medium is not to be construed as a transient signal per se, such as a radio wave or other freely propagating electromagnetic wave, an electromagnetic wave propagating through a waveguide or other transmission medium (e.g., a light pulse through a fiber optic cable), or an electrical signal transmitted through an electrical wire.

[0110] Example 2

[0111] Reference Figures 2 to 5 This is the second embodiment of the present invention. Different from the first embodiment, this embodiment provides a verification test of a Unity-based three-dimensional display method for a substation secondary optical circuit and associated devices, in order to verify and illustrate the technical effects adopted in this method.

[0112] Reference Figures 2 to 5 This is an experimental rendering of the method provided by the present invention. The present invention is based on the three-dimensional modeling display of the real scene of the substation, so that debugging and operation and maintenance personnel do not need to go to the substation site. They can determine and view the working scope that needs to be debugged and the related devices and pressure plate circuit breaker label information at "home", saving time and cost; based on the three-dimensional display of the secondary optical circuit and the device, the network topology relationship between complex devices is intuitively displayed; this system associates the electronic drawing data related to the device with the three-dimensional model of the device, making the drawing data easier to view and save, saving the time of debugging and operation and maintenance personnel to read a large amount of drawing data.

[0113] Taking the complete voltage loss of a 110kV substation as an example, the economic losses are as follows: 2 main transformers with a capacity of 63,000KVA, and an hourly power supply of approximately 2×63,000×0.85×1=107,100 kWh. Based on the actual average electricity price of 0.623 yuan achieved by the Gui'an Power Supply Bureau in 2020, the benefit is approximately 107,100×0.623=66,723 yuan / hour. The fault recovery is calculated based on 4 hours, which is approximately 270,000 yuan.

[0114] Therefore, the method provided by the present invention can effectively guide operation and maintenance personnel to carry out troubleshooting and maintenance of key circuits, reduce the number of false operations and refusal to operate of relay protection, reduce the erroneous sending and missing of automation signals, and ensure the safe operation of the power grid and equipment.

[0115] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
