[0055] The control panel has a variety of preset operating modes, such as normal operating mode, fault simulation mode, and self-healing demonstration mode. Users can use the control panel to select a specific simulation transformer module for power supply simulation, or select a specific pole module for line structure simulation. The panel allows users to trigger and control the status changes of the simulated line signal light module to simulate the normal operation, fault and recovery process of the line. The control function of the time display module allows users to set and adjust the display of time information to simulate the time requirements of distribution network operation. The control panel is equipped with a program selector for selecting different self-healing principles and operating processes for display. The program selector includes preset self-healing processes, such as voltage-time type, centralized control type, intelligent distributed type, etc. Users can select the corresponding process according to training needs.

[0056] The control panel in this embodiment provides an interactive operation mode with the simulation sandbox device, making the training and demonstration process more vivid and interesting; through the control panel, users can quickly switch between different simulation scenarios and operation modes, improving the efficiency and flexibility of training; the intuitive control panel design reduces the complexity of operation, allowing users to easily use the simulation sandbox device even without professional background; the control panel allows users to simulate and observe various operations and fault responses of the distribution network, deepening their understanding of distribution automation technology; users can conduct actual operation exercises through the control panel to improve their operating skills and fault handling capabilities of the distribution automation system; the versatility of the control panel enables the simulation sandbox device to meet different training needs and demonstration scenarios, and has good adaptability and scalability.

[0060] Furthermore, in some embodiments, the simulation transformer module includes a first transformer unit and a second transformer unit, the first transformer unit is used to power the simulation lines within a first preselected area of the simulation sandbox platform, and the second transformer unit is used to power the simulation lines within a second preselected area of the simulation sandbox platform.

[0061] Specifically, the simulated transformer module consists of two independent transformer units, each designed to simulate the main functions of an actual transformer, including voltage conversion and power supply. The first transformer unit and the second transformer unit may have different rated capacities and output voltages to simulate power supply conditions in different areas or under different load conditions in the distribution network. The simulation sandbox platform is divided into at least two pre-selected areas, each representing a specific part or area in the distribution network system. Each pre-selected area contains different simulated pole modules, simulated line signal light modules, etc. to demonstrate the structure and status of the distribution network in the area. Each transformer unit is equipped with necessary control and monitoring equipment, such as voltmeters, ammeters, protective relays, etc., to simulate the operating status and control logic of an actual transformer. The transformer unit can simulate various power supply conditions, including normal power supply, overload, voltage fluctuations, etc., as well as responses and protection actions in fault conditions.

[0062] By setting up two independent transformer units in this embodiment, the simulation sandbox device can more realistically reflect the power supply conditions and characteristics of different areas in the distribution network; users can learn about power supply management and fault handling in different areas through the simulation transformer module, thereby improving the comprehensiveness and depth of the training content; the simulation transformer module provides an opportunity to actually operate and control the transformer, enhancing the user's understanding of transformer operation and maintenance; by accurately simulating the power supply and protection functions of the transformer, the simulation sandbox device can accurately reproduce the system response under various fault conditions; users can practice a variety of power supply schemes and fault recovery strategies through the simulation transformer module, and cultivate flexible and diverse operating skills; the intuitive display and operation control of the simulation transformer module make the teaching process more vivid and interactive, which helps to improve the students' learning interest and participation; the design of the simulation transformer module enables the simulation sandbox device to adapt to different teaching and demonstration needs, and has good flexibility and scalability; through the operation and results of the simulation transformer module, trainers can more easily evaluate the students' operating skills and understanding, and provide timely feedback and guidance.

[0063] Furthermore, in some embodiments, the time display module includes a first time display screen and a second time display screen, the first time display screen is used to display time change information during the distribution network automation simulation process, and the second time display screen is used to display the remaining time during the simulated closing process.

[0064] Specifically, the time display module consists of two dedicated display screens, each of which is responsible for different time display tasks to provide detailed time information about the simulated distribution network operation. The first time display screen may be used to display the total operating time from the start of the simulation to the current time, or the time stamp of a specific operation, such as fault detection time, isolation time, etc. The second time display screen is specifically used to count down during the simulated closing operation to simulate the time pressure and urgency in actual distribution network operations. These two display screens can use LED, LCD or OLED technology to ensure high visibility and clear information display. The display screen has high contrast and brightness adjustment functions to adapt to different viewing environments and user needs. The content and format of the display screen can be configured through the control panel to adapt to different simulation scenarios and user needs. The display screen includes an automatic refresh function to update the time information in real time to ensure the continuity and accuracy of the simulated operation.

[0066] Furthermore, in some embodiments, the analog line signal light module includes a plurality of analog line signal lights, and the analog line signal lights are configured to indicate different line states by displaying at least two colors.

[0067] Specifically, the simulated line signal light module consists of a set of signal lights, each of which represents the status of a specific line or device in the distribution network. The signal lights can use LED technology to provide high brightness and low energy consumption, while ensuring long life and high reliability. The signal lights are designed to display at least two colors, usually red and green, to simulate the normal operation and fault conditions of the lines in the actual distribution network. A red signal usually indicates a problem with the line, such as a fault, overload, or maintenance status, which requires operator attention or action. A green signal indicates that the line is in normal operation, the power supply is stable, and no additional operation is required. Buttons or other input devices on the control panel are used to trigger the color change of the signal lights to simulate changes in line status. The changes in the signal lights are closely synchronized with the operations of the simulated transformer module and the simulated pole module to ensure the authenticity and accuracy of the simulated scenario.

[0069] Furthermore, in some embodiments, the distribution network automation simulation sandbox device further includes a multimedia module, and the multimedia module is used to play audio and video synchronized with the operation of the distribution network automation simulation sandbox device.

[0070] Specifically, the multimedia module is an important component of the distribution network automation simulation sandbox device. It includes audio output devices such as speakers and video display devices such as screens or projectors. This module is designed to enhance the interactivity and educational effectiveness of the simulation sandbox and provide richer information through visual and auditory elements. The multimedia module can play corresponding audio and video content based on real-time operations on the simulation sandbox, such as warning sounds when faults occur and operation guidance videos. This synchronized playback function can enhance users' understanding and memory of the consequences of simulated operations. The multimedia module can include a built-in or external storage device for storing multimedia content related to the simulated operations. The control panel can include an interface for selecting and controlling the playback of multimedia content, such as control buttons such as play, pause, and skip.

[0071] In this embodiment, with the assistance of audio and video, users can obtain a more vivid and intuitive learning experience, thereby improving their interest and participation in learning; multimedia content can provide additional explanations and guidance to help users better understand complex distribution network automation concepts and operating procedures; synchronized multimedia playback can provide instant feedback on operation results, accelerating the user's learning process of simulated sandbox operations; the dual stimulation of vision and hearing helps users to remember operation steps and troubleshooting processes more deeply; the multimedia module can be used to showcase the latest technologies and development trends in distribution network automation, and promote the dissemination and updating of knowledge; users can interact more deeply with the simulated sandbox through the multimedia module, thereby improving their sense of participation in training and actual operation experience; teachers or trainers can use the multimedia module to conduct more effective teaching demonstrations, improving teaching effectiveness and students' understanding.

[0072] In a specific embodiment, Figure 2 and 3 As shown, this embodiment also provides a specific structure of a distribution network automation simulation sandbox device, including a simulation sandbox (1), a transformer ① (2), a pole (3), a transformer ② (4), a simulation line signal light (5), a time display screen ① (6) and a time display screen ② (7); wherein, the simulation sandbox (1): is the basis of the entire system, displaying all simulation components. Transformer ① (2): is used to supply power to the simulation line in the left frame selection area. Pole (3): is used to simulate the pole and the distribution line around it as part of the entire system. Transformer ② (4): is used to supply power to the simulation line in the right frame selection area. Simulation line signal light (5): is used to indicate the status of the simulation line, and displays the working status of the line by switching between red and green lights. Time display screen ① (6): is used to display the change of time during the simulation process. Time display screen ② (7): is used to display the countdown of time during the simulation closing process to indicate the process of restoring power supply.

[0073] The different models on the sandbox (such as transformers, poles, signal lights, and time display screens) combined with voice explanations and light changes show the entire process from the occurrence of a distribution line fault to the restoration of power supply, helping users understand various fault handling and automated recovery logic. The overall base is a simulation sandbox (1), on which models such as transformer ① (1), pole (3), transformer ② (4), simulated line signal lights (5), time display screen ① (6), and time display screen ② (7) are distributed to simulate the process of the distribution network system and the intelligent circuit breaker from isolating the fault to restoring power supply. The simulated line signal lights (5) are simulated lines.

[0074] like Figure 2 and Figure 3When the simulated line is working normally, the simulated line signal light (5) in the area selected by the left frame is powered by transformer ① (1), and the simulated line signal light (5) in the area selected by the right frame is powered by transformer ② (4). When the simulated line has no fault, the simulated line signal lights (5) on both sides are red. The distribution network automation function simulation sandbox only simulates the line fault at the power supply end of transformer ② (4); when a fault occurs in any area line, if it is a transient fault, it will automatically avoid and restore power supply, and the simulated line signal light (5) will light up red again; if it is a permanent fault, it will trip again, and the protection at both ends of the area line section will be turned on, and the green light will be turned on. The simulated line signal light (5) will start to supply power from the transformer again. When the closing simulation is repeated, the closing will be counted down through the time display screen ② (7). When the time on the time display screen ② (7) counts down to 7 seconds, the red lights will light up in sequence to simulate the closing state of the line. The time display screen ② (7) is set around the simulated pole (3), and the line simulation state is simulated with two poles as one interval.

[0075] In summary, this embodiment provides a sandbox device for simulating distribution network automation functions. The sandbox utilizes a transparent material and uses voice and lighting to intuitively understand the distribution network self-healing process and the related functions of each circuit breaker device. The control panel covers various distribution network automation self-healing principles, and the sandbox model can demonstrate common distribution network structures. The sandbox can also display the self-healing process in different wiring scenarios and different principles. The sandbox is lightweight, compact, and easy to carry. Compared to existing technologies, this embodiment visualizes the protection functions of intelligent circuit breakers and the entire distribution network process from fault isolation to power restoration, fundamentally addressing the issues of staff's lack of professional expertise and limited understanding. This intuitive sandbox model allows laypeople to gain a deeper understanding of the intelligent distribution network. Government officials or professionals can showcase the company's technological prowess during inspections of the innovation studio, enhancing the company's image. This helps transitioning and new employees gain a comprehensive understanding of the intelligent distribution network, addressing the current situation of limited on-site observation and comprehensive imagination.

[0076] It can be seen that this embodiment provides a distribution network automation function simulation sandbox. The sandbox uses different colors of lights and voice explanations to intuitively demonstrate different principles (voltage-time type, centralized control type, intelligent distributed) and other self-healing action processes on the model.

This method can be executed on the aforementioned distribution network automation simulation sandbox device and can specifically include the following steps:

[0079] S1. Start the distribution network automation simulation sandbox device to display the initial state of the distribution network system;

[0080] Specifically, in step S1, at the start of the simulation, the simulation sandbox device is activated via the control panel, and all modules are configured according to the preset initial states. For example, the simulated transformer module begins supplying power, and the simulated pole module displays a normal line structure. The simulated line signal light module and the time display module are also configured according to the initial states. For example, the signal light turns green to indicate a normal line, and the time display module is ready to count.

[0081] S2. Use the transformer simulation module to simulate the power supply to the distribution network system, and use the pole simulation module to simulate the structure of the pole and the distribution line within the preset range;

[0082] Specifically, in step S2, the transformer simulation module begins simulating power supply according to preset parameters, while the pole simulation module displays the physical layout and connection of distribution lines. The combination of these modules simulates the power supply and line structure of a real distribution network system, providing a foundation for subsequent fault simulation and operation.

[0083] S3. Trigger a simulated fault on the control panel to demonstrate the distribution network system's fault response process;

[0084] Specifically, in step S3, the operator can select a preset fault type, such as a transient fault or a permanent fault, through the control panel and trigger it on the simulation sandbox. Triggering a simulated fault immediately affects the state of the simulated line signal light module. For example, if the signal light changes from green to red or yellow, it indicates a line fault.

[0085] S4. Use the simulated line signal light module to simulate the working status of the distribution line to demonstrate the process of fault isolation and power restoration;

[0086] Specifically, in step S4, after a simulated fault is triggered, the simulated sandbox device displays the distribution network system's fault detection, isolation, and power restoration process. The simulated line signal light module changes color based on the fault type and processing results. For example, after the fault is isolated, the affected line signal light turns yellow or green.

[0087] S5. Display the time information of the simulated distribution network operation through the time display module;

[0088] Specifically, for step S5, the time display module records and displays key time points of fault handling, such as fault detection time, isolation time, power restoration time, etc.

[0089] In a specific embodiment, the following process may be included:

[0090] 1. Initial state: The analog line works normally.

[0091] Operation: When the sandbox model is started, all simulated line signal lights (5) work normally and display red lights, indicating that the distribution lines are in normal power supply status.

[0092] Status: The analog line signal lights inside the left frame selection area are powered by transformer ①(2), and the analog line signal lights inside the right frame selection area are powered by transformer ②(4).

[0093] 2. Fault occurrence: Transient faults are automatically avoided and power supply is restored.

[0094] Operation: During the simulation, the user can trigger a transient fault through the control panel or buttons. At this time, the model will simulate a fault on a certain section of the line (for example, the line in the area selected by the right box).

[0095] Status: In the simulation sandbox, if the simulated line signal light (5) in the right framed area goes out, it means that a fault has occurred in the line segment. At this time, the intelligent circuit breaker will detect a transient fault.

[0096] Response: The intelligent circuit breaker automatically performs avoidance actions to prevent the fault from further affecting the entire power distribution system. After the fault is eliminated, the circuit breaker automatically recovers and the simulated line signal light (5) turns red again, indicating that the line has resumed power supply.

[0097] 3. Fault occurs: permanent fault, trips again.

[0098] Operation: If the fault is permanent, after a short recovery period the faulty section will trip again. The user can trigger a permanent fault via the control panel or buttons.

[0099] Status: A permanent fault causes the faulty section to trip again after reclosing. At this time, the analog line signal light (5) in the right framed area goes out. The intelligent circuit breaker recognizes that there is a permanent fault in the section. If a short circuit fault occurs in the branch, the branch circuit breaker trips for protection.

[0100] Response: The circuit breaker activates protection, shutting off power to the faulty section and simultaneously triggering the protection mechanism. The signal lights at both ends of the faulty section turn green, indicating that the line is isolated.

[0101] 4. Fault isolation is complete.

[0102] Operation: After the fault section is isolated, the intelligent circuit breaker will start the fault isolation program. This program will guide the user through the fault isolation process through lighting and voice instructions.

[0103] Status: The analog line signal lights (5) at both ends of the fault section remain green, indicating that the section has been isolated and no longer supplies power. At the same time, the time display ② (7) will start counting down to display the closing time.

[0104] 5. Restore normal power supply to the section.

[0105] Operation: After the fault is isolated, the system will start the recovery program and restore the power supply to the normal power supply section through the intelligent circuit breaker.

[0106] Status: The time display screen ②(7) starts counting down. When the countdown reaches 7 seconds, the system closes the circuit breakers one by one, and the simulated line signal light (5) gradually changes from green to red, indicating that the line power supply has been restored.

[0107] Response: The entire closing process is displayed through the changes in the time display screen ②(7) and the simulated line signal light (5). Users can observe the power supply recovery process through the model.

[0108] 6. Return to normal state.

[0109] Operation: After the power supply is restored, the system enters the normal state, and all analog line signal lights (5) show red lights, indicating that the entire distribution network system has resumed normal power supply.

[0110] Status: All traffic lights within the left and right selected areas return to normal display, and the model demonstration is completed.
