[0002] With the development of science and technology, automation technology has been widely used in distribution networks. The in-depth application of distribution automation technology has not only shortened the power outage time of distribution network faults, improved the operation and management level, but also improved the power supply quality. The current distribution automation master station system has the functions of distributed power supply access control, large-scale power outage processing, "two remote" terminal data access, and distribution terminal management. Among them, the "two remote" terminal data access and distribution terminal management functions carry the work tasks of the distribution automation terminal access to the main station operation acceptance. When the on-site equipment is connected to the main station, it often needs to be put into operation after point-to-point acceptance.

[0003] At present, the common distribution automation terminal system mainly establishes a simulated master station, verifies the signal generation locally, and then conducts joint debugging and point-to-point with the master station. The specific method is that the on-site personnel increase the quantity and operate the action, and then check the results with the master station personnel by phone. This method relies on careful arrangements in the early stage, and the on-site acceptance work takes a lot of time and manpower. The main shortcomings are as follows: (1) Unbalanced terminal investment and high manpower investment. The transmission test between the distribution terminal and the distribution master station is completed manually, which has problems such as long test time and high error probability. The number of terminals that need to be connected and replaced each month is divided into batches, the work is unbalanced, and the phenomenon of adding people to rush the work often occurs. (2) Lack of information means and heavy debugging burden. When the distribution automation terminal is connected to the master station for on-site acceptance, the master station personnel need to participate in the whole process and formulate a paper plan to proceed in sequence. The flexibility is not high and it takes up a lot of time for the master station personnel. The debugging process record is simple, lacks detailed operation increase records, is not standardized and rigorous, and it is easy to cause the equipment to be put into use with defects. (3) High dependence on communication and low coordination efficiency. The manual joint debugging test mode of telephone communication appointment time is prone to delays in debugging when encountering problems or changes in plans, and it is more difficult for the master station to coordinate with the site. In order to standardize the access debugging of distribution terminals, improve the intelligent recognition of real-time data by the master station during the joint debugging process, realize the adaptive debugging and inspection of various distribution automation terminal access, and solve the problem of low debugging efficiency, a good automation solution is urgently needed to standardize and simplify the complex distribution terminal access acceptance work.

[0004] In view of the above problems, a method and system for automatic joint debugging of distribution automation terminals are needed to reduce the occupancy of master station personnel, free up the work of master station coordinating personnel, and automatically stimulate the distribution automation terminal to generate signals.

[0005] The patent document with document number CN114371355A discloses an adaptive joint debugging system for realizing multi-interval point-to-point testing of distribution automation terminals, including a distribution automation master station, a distribution automation terminal and a joint debugging device. The application scheme can realize full-interval point-to-point testing through one wiring, improve the debugging efficiency, correctness and completeness of the distribution automation terminal, and reduce the failure rate caused by debugging. However, it also has the following problems: 1. The system structure is not disclosed; 2. The standardization and simplification of the complex distribution terminal access acceptance work is not enough. Summary of the invention

[0037] At present, the distribution automation terminal system has problems such as unbalanced terminal investment, high manpower investment, lack of information means, heavy debugging burden, high dependence on communications, and low coordination efficiency.

[0038] In view of the above problems, the present invention discloses a distribution automation terminal automatic joint debugging system, such as Figure 3 As shown, the system includes:

[0039] Data storage layer: saves business data generated by application logic;

[0040] Application logic layer: used to implement various application functions and business logic, and support users' remote operations and decision-making;

[0043] The user view layer is used to control the debugging system through a visual interface.

[0044] The data storage layer includes the organization, storage and processing of data. At this layer, the system implements the preservation of business data generated by all application logic on the automation master station side, mainly through the relational database DAMO. At the distribution automation terminal, cache management is performed through the local cache database, mainly through the Redis database for data storage and extraction.

[0045] Application logic layer: This layer is the core of the system and is responsible for implementing various application functions and business logic. It includes modules such as acceptance testing, report generation, solution configuration, task management, and problem diagnosis. The system can provide early warning and alarm information based on fault diagnosis results and data analysis, perform equipment management and optimization, and support users' remote operations and decision-making.

The Web page can display the acceptance tasks, details and statistical analysis; the embedded client program is installed on the tester, and the user can operate the acceptance start and stop through touch commands and view the real-time acceptance signal.

[0049] In combination with the above system, the present invention also discloses a method for automatic joint debugging of distribution automation terminals, the flow chart of which is as follows: Figure 1 , 2 As shown. The steps include:

[0050] S1. Customize the debugging strategy set of the power distribution terminal to be accepted to form a test plan;

[0051] The debugging strategy is to determine the debugging standards and processes. The system can provide flexible debugging strategy settings according to different project requirements and specifications. The debugging strategy includes debugging standards, dosage types and parameter requirements.

[0052] The test plan is a detailed plan and steps compiled according to the specific project requirements. The test plan includes test items such as telemetry test, remote control test, remote signal test and remote adjustment test. Specifically:

[0053] Telemetry testing refers to the measurement data in the remote detection system, such as current, voltage, power, etc., to obtain the sampling performance parameters of each device in real time. In the telemetry function test, instructions will be sent to the distribution automation terminal to confirm that it can accurately collect and transmit measurement data to ensure the accuracy and reliability of the telemetry function.

[0054] Remote control testing refers to the operation commands in the remote control system, mainly the remote opening and closing of circuit breakers, to achieve remote control of the equipment. In the remote control function test, instructions will be sent to the distribution automation terminal to confirm that it can accurately perform the corresponding operations according to the instructions, so as to verify the correctness and reliability of the remote control function.

[0055] Telesignaling test refers to the status change or event notification in the remote information system, such as switch status, alarm information, etc. In the telesignaling function test, different status changes or event triggers will be simulated to check whether the distribution automation terminal can accurately receive and process the corresponding telesignaling information to ensure the reliability and stability of the telesignaling function.

[0056] The remote adjustment test function mainly refers to the adjustment and configuration of the parameters of the distribution terminal equipment by remote means, such as adjusting the function of the distribution automation terminal, voltage and current limit, etc.

[0057] The host can customize the set of debugging strategies for the automated terminals to be accepted to form a test plan.

[0058] S2. The host executes the strategy control according to the test plan, stimulates the output of the power source and records the process;

[0059] During debugging, the host automatically accepts according to the test plan strategy, executes the corresponding control commands, stimulates the output of the power source and records the process.

[0060] S3. The power source generates an excitation signal according to the host's strategy control, which stimulates the distribution terminal to be accepted to send a signal to the automation master station.

[0061] According to the acceptance test requirements, the power source receives the control command from the host and generates a current or voltage analog sequence with controllable size, duration and step length as an excitation signal, which stimulates the distribution automation terminal to send a signal to the master station.

[0062] S4. The automation master station receives the sent signal and feeds back the signal to the test master station.

[0063] The test master station is deployed in the automation master station, and the test master station can achieve two-way data connection with the real distribution automation master station.

[0064] S5. The test master station can poll the real-time data of the automated master station after the test scheme is stimulated according to the expected value, and transmit the result back to the host.

[0065] The test master station can obtain the test signal of the host through wireless communication. The host informs the test master station through the test signal. The master station generates an expected value based on the test signal. The test master station can poll the real-time data of the automation master station after the expected value and the on-site stimulation of the distribution automation terminal, and feedback the automation host result signal to the host.

[0066] Furthermore, the host machine and the power source are separately set, and the FTU and other distribution terminals require operation and maintenance personnel to climb up the tower to open the FTU cabinet for operation, which not only consumes physical strength but also increases the difficulty of maintenance. To address this problem, the power source and the host machine are separated and a split structure is adopted to reduce the weight of the operating part of the device.

[0067] Through the use of the above-mentioned system settings and methods, the system can automatically generate a complete debugging report according to the debugging standards and specifications; it can also search for debugging tasks and list the debugging status and results of signals under all tasks; it can analyze the debugging data and display it visually, including debugging signal statistics, display of debugging equipment types and quantities, display of debugging progress, etc.; it can help to quickly identify and locate problems through real-time detection and data analysis of terminal equipment. It can determine whether the point table meets the requirements, whether the diagram maintenance meets the requirements, determine the main station signal data, and diagnose whether the communication message is sent and received at the main station. It can greatly reduce the time and cost of manual troubleshooting and diagnosis, and improve the efficiency and accuracy of fault handling.

[0068] In addition, compared with the pen and paper recording or information entry method before the application of the system of the present invention, the test report accurately records the test and comparison process, and the source of the result data can be traced back, forming an accurate acceptance report, which can further tighten the management of the distribution terminal before it goes online and pass the last checkpoint of the equipment commissioning.

[0069] Solution application example: Use blind evaluation to conduct field tests on the distribution automation terminal warehouse adjustment system. Do not inform the equipment model and debugging location, and debug directly on site. The test site is selected in the area of ​​the automation master station, and mainly conducts joint debugging tests of the distribution automation terminal accessing the automation master station.

[0070] A total of four distribution automation terminals from different types of manufacturers were tested. After the duration was recorded through manual testing, the system of the present invention was used to conduct tests and evaluate the terminals by comparing the duration and results.

[0071] The on-site statistical results show that, using the system and method of the present invention, from the start of testing to obtaining the acceptance report, it only takes an average of 0.5 man-hours to complete the acceptance of a 4-bay power distribution terminal, which is more than 90% less than the time required for the master station personnel to cooperate in the past, thus reducing the workload of the master station personnel. Compared with the previous work time consumption of 4 man-hours (including the master station manpower), the acceptance efficiency is at least increased by more than 80%, which improves work efficiency and indirectly reduces the difficulty of frequently coordinating the master station personnel to find problems.
