[0002] In the development of today's power system, the construction of smart grids has become a key way to improve energy utilization efficiency and service quality. As an important part of the smart grid, the level of automation and intelligence of the distribution network is directly related to the stable operation and fault response capability of the power grid. In recent years, with the continuous advancement of intelligent sensing technology, the fault detection technology of the distribution network has been significantly improved. By deploying various sensors and monitoring equipment, the system can monitor the status of the power grid in real time and quickly locate the problem point when a fault occurs. At the same time, the informatization construction of the dispatching system also provides strong technical support for the operation and management of the distribution network. Dispatchers can rely on the integrated platform to monitor and dispatch the power grid in real time.

[0003] Nevertheless, the existing distribution network fault handling technology still faces many challenges in practical applications. Although intelligent sensing technology can automatically detect distribution network fault information, the existing system still has a lot of room for improvement in the real-time and accuracy of information push. Dispatchers often find it difficult to obtain accurate fault information in the first time, which undoubtedly increases the difficulty and duration of fault handling. The current technology is insufficient in establishing a unified view model of the distribution network, resulting in a lack of comprehensive and intuitive data support for dispatchers when handling faults. The incompleteness of information limits the dispatcher's rapid assessment and decision-making on fault conditions. The existing system is still insufficient in automated fault handling and lacks an effective automatic driving interface to assist in generating operation tickets, resulting in a cumbersome and inefficient fault handling process, which not only prolongs the fault recovery time, but may also further affect the stable operation of the power grid. The graphical command method based on multi-system interactive distribution network faults of the present invention aims to overcome these limitations and achieve rapid response and precise command of fault handling through real-time and accurate information push, comprehensive data integration and efficient automated processing.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0022] Example 1, reference Figure 1, is an embodiment of the present invention, and provides a graphical command method based on multi-system interactive distribution network faults, comprising:

[0023] S1: Automatically detect distribution network fault information through intelligent sensing technology and push the distribution network fault information to the dispatcher.

[0024] Furthermore, intelligent sensing technology includes real-time monitoring of the operating status of the distribution network, automatic capture of fault signals, and after detecting abnormal conditions such as feeder tripping, equipment overload and busbar pressure loss, the relevant data is transmitted to the command system. When a fault occurs, it is linked with the graphical interface to automatically prompt the fault location and nature, obtain fault information in real time, and locate the fault source through the graphical display interface.

[0025] It should be noted that the intelligent sensing technology is used to automatically detect distribution network fault information and push the distribution network fault information to the dispatcher, realizing real-time monitoring and transmission of fault information. It can capture abnormal signals at the first time when the fault occurs, and automatically prompt the fault location and nature through the system, thereby improving the timeliness of fault handling, shortening the power supply interruption time that may be caused by delayed fault handling, and providing a basis for rapid response in subsequent steps.

[0026] S2: Establish a unified view model of the distribution network and integrate key data for dispatchers’ reference.

[0027] Furthermore, establishing a unified view model for the distribution network includes establishing a graphical command model to display the power supply path of the distribution network, show the location and status of each line, feeder and switch device, and automatically color it according to the real-time status of the switch. The normal power supply, power outage and maintenance sections are marked with different colors in the interface to identify the location of the fault and the line status.

[0028] It should be noted that the integration of key data includes integrating the equipment topology relationship of various power grid systems through a graphical command model, combining asset ledgers and geographic information system data, providing a visual layout of the power grid structure, and centralizing real-time measurement data scattered in different business systems into a unified view, so that equipment operating status and fault information can be intuitively viewed in the same interface.

[0029] It should also be noted that the establishment of a unified view model for the distribution network integrates key data for dispatchers' reference, realizes the comprehensive visualization of the grid operation status, and provides a centralized information platform, so that dispatchers can intuitively view the equipment operation status and fault information in one interface, thereby improving the efficiency of information processing, enhancing the dispatchers' control over the grid status, optimizing the decision-making process, and reducing the risk of misjudgment due to information dispersion.

[0030] S3: Automatically handle faults through the autonomous driving interface and generate operation tickets.

[0031] Furthermore, the autonomous driving interface includes generating standardized operation tickets based on fault logs and data in the system during the fault isolation phase for the dispatcher to review and confirm. During the fault handling phase, the preset recovery operation steps are executed according to the generated operation tickets, and combined with the on-site personnel sign-off function, the on-site equipment executes in sequence according to the predetermined procedures after the instructions are issued.

[0032] It should be noted that the autonomous driving interface also includes the dispatcher clicking switches and lines on the graphical interface to generate fault briefings, automatically record fault event information, and save it in a standardized format. The interactive interface module is connected to the distribution management system and operation control system to obtain and synchronize fault handling information in real time.

[0033] It should also be noted that the generation of an operation ticket includes remote monitoring and on-site confirmation of the power restoration process in non-fault sections, real-time tracking of the progress of the power restoration operation when the dispatcher is operating, and generation of an operation log, coordinated on-site confirmation and remote monitoring, and confirmation of the location and status based on on-site personnel at each key node of power restoration.

[0034] It should also be noted that in the fault handling link, the preset recovery operation steps are executed according to the generated operation ticket. The specific steps are as follows: after the fault occurs, the intelligent fault perception module detects the fault information and transmits it to the system. The system automatically generates a standardized operation ticket through the operation ticket generation module according to the fault type and the preset recovery process; after receiving the operation ticket, the dispatcher reviews and confirms it to ensure that the operation steps are correct. The approved operation ticket is distributed to the on-site operators and maintenance team. The on-site operators prepare the necessary tools, equipment and safety measures according to the instructions in the operation ticket, and perform recovery operations in the order of steps on the operation ticket, such as switching switches, closing or disconnecting lines, and checking equipment. After completing each step, the on-site operator will mark the confirmation on the operation ticket and record the operation time and status; The dispatcher monitors the operation progress in real time through the graphical command model, maintains communication with the on-site operators, and coordinates the operation steps. If necessary, the dispatcher can adjust the steps in the operation ticket according to the on-site situation. After each key operation step is completed, the on-site operator needs to confirm the operation result and report the status to the dispatcher. The dispatcher updates the equipment status on the graphical interface based on the on-site feedback; after all the steps in the operation ticket are executed, the on-site operator makes a final confirmation of the recovery result. The dispatcher records the completion of the fault handling in the system and generates an operation log, including the operation steps, time, personnel and results; after the fault handling is completed, the system collects the operation log and fault handling data for analysis, and optimizes the operation ticket generation logic and recovery operation process based on the analysis results to improve the efficiency and safety of future fault handling.

[0035] It should also be noted that, combined with the on-site personnel signing function, the on-site equipment executes in sequence according to the predetermined procedure after the instruction is issued. The specific process of execution in sequence is: First, the dispatcher or automation system issues an operation instruction through the graphical command interface, and the instruction is sent to the control system of the on-site equipment through the communication network. After receiving the instruction, the control system of the on-site equipment first parses the instruction to clarify the type of operation and the target device to be performed, and performs a pre-inspection process according to the operation type to check whether the status of the target device meets the operating conditions, such as whether the equipment is in a safe state and whether it has the operating conditions; the control system sorts the instructions according to the preset operating procedures to ensure that the order of operations is correct. The control system sends operation commands to the on-site equipment in sequence, and the equipment executes according to the following steps: The most urgent or basic operations are executed first. operations, such as isolating faulty equipment; after completion, the system confirms the operation results and reports to the dispatcher; if the operation is successful, the control system continues to send the next operation instruction; repeat the confirmation and execution process until all operation instructions are executed; after each operation is completed, the field equipment will feedback the execution status (success or failure) to the control system, and the control system will update the equipment status based on the feedback and display it on the graphical interface; if an abnormality or operation failure is encountered during the execution process, the control system will process it according to the preset logic: try to re-execute the operation and issue an alarm to notify the dispatcher, and stop subsequent operations according to the preset safety procedures to prevent potential dangers; the control system records detailed information for each operation, including operation time and execution results. Finally, the system generates an operation report for the dispatcher to review and archive.

[0036] It should also be noted that by automating fault handling through the autonomous driving interface and generating operation tickets, fault handling can be standardized and automated, manual operation steps can be reduced, the accuracy of fault handling can be improved, the speed and safety of fault recovery can be improved, human errors can be reduced, and the stable operation of the power grid can be ensured.

[0037] Example 2 is an embodiment of the present invention, which provides a graphical command method for multi-system interactive distribution network faults. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0038] Firstly, the experiment was carried out in a medium-sized distribution network, including multiple feeders, switchgear and busbars. An intelligent sensing system was deployed to monitor the operation status of the power grid in real time through sensors installed at key nodes. When abnormal conditions such as feeder tripping, equipment overload or busbar pressure loss were detected, the system immediately captured the fault signal and transmitted the relevant data to the command system. The system was linked with the graphical interface to display the fault location and nature in real time, providing intuitive fault information for the dispatcher. A unified view model of the distribution network was established to integrate the equipment topology relationship, real-time measurement data and geographic information system data of the power grid. The model displayed the power supply path of the distribution network through a graphical interface and automatically colored it according to the real-time status of the equipment, using different colors to identify the normal power supply, power outage and maintenance sections. The fault was automatically processed through the automatic driving interface. In the fault isolation stage, the system generated a standardized operation ticket based on the fault log and real-time data. After the dispatcher reviewed and confirmed it, the system executed the preset recovery operation steps. After the instructions were issued, the on-site equipment executed them in sequence according to the predetermined procedures, realizing the standardization and automation of fault processing. It can be seen from the experimental results that the present invention has advantages in information processing efficiency, fault processing accuracy and stability of power grid operation.
