[0031] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0033] According to an embodiment of the present invention, an embodiment of a warehouse adjustment system for power distribution terminal equipment is provided. Figure 1 is a schematic diagram of a warehouse adjustment system for a power distribution terminal device according to an embodiment of the present invention. Figure 1 As shown, the system 10 includes: a warehouse module 12, a master station security access module 14, and a master station module 16. The warehouse module 12 is connected to at least one power distribution terminal device 18 ( Figure 1 Only one connection is shown in the figure, the master station security access module 14 is connected to the distribution network 110 and the warehouse module 12, and the master station module 16 is connected to the master station security access module 14.

[0034] It should be noted that to build an automatic warehouse adjustment system for distribution automation terminals, it is necessary to first analyze the problems existing in traditional warehouse adjustment technologies, and then analyze the functions of the distribution network operation and control system (Distribution Network Operation and Control System, referred to as distribution network OCS system). To improve the standardization of distribution terminal access debugging, and enhance the intelligent processing capability of the distribution network OCS system for real-time data during the joint debugging stage. To achieve adaptive access adjustment and testing of distribution automation terminals, and solve the problem of low efficiency of the existing debugging process. The overall architecture has three modules: master station security access module, master station module and warehouse module. Among them, the warehouse module is used to store and manage at least one distribution terminal device; the master station security access module is used to collect the status information of the distribution network and warehouse module, and process the collected status information; the master station module is used to monitor and manage the master station security access module and the warehouse module.

[0035] Figure 2 Schematic diagram of an optional warehouse adjustment system architecture according to an embodiment of the present invention. Figure 2 As shown in the figure, the master station security access module is the core part of the entire warehouse dispatching system, which is responsible for receiving data from various subsystems, processing and analyzing. Among them, the distribution network automation master station device is mainly responsible for communicating with the distribution network and collecting the status information of the distribution network. The master station server is responsible for processing and storing the collected data; among them, the master station module is an important part of the warehouse dispatching system, which is mainly responsible for monitoring and managing the entire system. Among them, the master station server is responsible for summarizing and processing the data of the master station security access area and the warehouse. The debugging management system is responsible for debugging and maintaining the entire system and presenting it to the operators through the web page (Web); among them, the warehouse module is another important component of the warehouse dispatching system, which is mainly used to store and manage various equipment and unit modules. Among them, the encryption unit and the encryption sending unit are responsible for encrypting and decrypting data to ensure the security of data transmission. The communication interface unit is responsible for communicating with external devices. The warehouse diagnostic unit is responsible for fault detection and diagnosis of equipment in the warehouse. The standard source test unit is used to test and calibrate the equipment under test. The tested communication unit and the tested protection measurement and control unit are equipment that needs to be tested and maintained.

[0036] It should be noted that the distribution network OCS system is an advanced automation control center specially designed for remote monitoring and control of the operation status of the power network. Its core functions include efficient management of the distribution network, such as real-time fault detection, accurate location and isolation of problem areas, and rapid restoration of power supply to non-fault areas after the fault is resolved. Through these functions, the system can not only significantly reduce the time required for fault repair, but also minimize errors in human operation, thereby improving the stability and efficiency of the entire power network. The specific functional architecture is as follows: Figure 3 shown. Figure 3 is a schematic diagram of a functional architecture of an optional warehouse adjustment system according to an embodiment of the present invention, such as Figure 3 As shown in the figure, the warehouse adjustment system includes: fault detection and processing, automatic positioning and isolation, rapid power restoration in non-fault areas, and planned power outage management. Among them, fault detection and processing are used to identify power grid faults, evaluate the type and severity of faults, and automatically generate targeted accident handling plans. Automatic positioning and isolation are used to locate the fault location, and use monitoring technology and equipment positioning to automatically isolate the fault area. Rapid power restoration in non-fault areas is used to execute the power restoration procedure, which requires the system to confirm that there will be no threat to the operation of the power grid and restore power supply to non-fault areas. Planned power outage management is used to accurately control the time and scope of power outages, and automatically arrange and execute planned power outages. Through fault detection and processing, automatic positioning and isolation, rapid power restoration in non-fault areas, and planned power outage management, the intelligent management level of the distribution network can be significantly improved.

[0037] It should be noted that the distribution network OCS system and the automatic warehouse adjustment system need to be closely integrated. The distribution network OCS system and the automatic warehouse adjustment system exchange data in real time through a security protocol, and coordinate with each other when a power grid fault is detected to quickly isolate the fault and deploy repair resources. The automatic warehouse adjustment system is also responsible for automated testing and acceptance of distribution terminal equipment to ensure that it meets the standards. In addition, the planned power outage management function is also integrated to ensure that relevant resources and personnel are properly arranged. The specific relationship model is as follows: Figure 4 shown. Figure 4 FIG. 1 is a schematic diagram of an optional relationship model between a distribution network OCS system and an automatic warehouse adjustment system according to an embodiment of the present invention. Figure 4 As shown, the automatic warehouse adjustment system is connected to the distribution network OCS system in communication, and the distribution network OCS system is connected to the distribution terminal in communication. The automatic warehouse adjustment system includes remote adjustment, remote control, telemetry and telesignaling functions, and can exchange data with the distribution network OCS system in real time. The distribution network OCS system includes fault detection, fault location, automatic isolation and planned power outage functions, and can send commands or return results to the automatic warehouse adjustment system. At the same time, the distribution network OCS system can also send execution commands or return results to the distribution terminal, and perform automated testing and acceptance with the distribution terminal. The distribution terminal includes at least the following functions: data acquisition, status monitoring and remote control operation.

[0038] Such a solution aims to simplify the complex acceptance work, standardize and simplify it, and at the same time improve the intelligent recognition ability of the distribution network OCS system in real-time data processing. This will help to adaptively adjust and verify the access of different types of distribution automation terminals, thereby significantly improving the efficiency and accuracy of the commissioning process.

[0039] The function of the automatic warehouse adjustment system is closely related to the distribution network automation. On the basis of the existing intelligent warehouse adjustment function of the distribution network OCS system, the remote adjustment and remote control automatic debugging functions are further integrated. This enables the distribution network OCS system to receive remote adjustment and remote control instructions from the debugger, and automatically execute these instructions after manual review and confirmation. After the execution is completed, the system will feedback the results to the debugger, and the debugger will record the complete debugging process including remote adjustment and remote control in the debugging report. The specific functions to realize the automatic debugging function include: fixed value parameter modification, fixed value parameter review, fixed value area switching, fixed value area query, switch remote control, and safety verification function. Figure 5 FIG. 1 is an interactive schematic diagram of an optional fixed value parameter modification and fixed value parameter retrieval process according to an embodiment of the present invention. Figure 5 As shown, the automatic warehouse adjustment system will first send a fixed value modification command to the distribution network OCS system. After receiving the fixed value modification command, the distribution network OCS system will send a fixed value modification preset command to the distribution terminal. After receiving the fixed value modification preset command, the distribution terminal will return the fixed value modification preset result to the distribution network OCS system. The distribution network OCS system will send a fixed value modification execution command to the distribution terminal. The distribution terminal will return the fixed value modification execution result to the distribution network OCS system. The distribution network OCS system will send the fixed value modification execution result to the automatic warehouse adjustment system. After receiving the fixed value modification execution result, the automatic warehouse adjustment system will send a fixed value review command to the distribution network OCS system. The distribution network OCS system will send a fixed value review command to the distribution terminal. The distribution terminal will return the fixed value review result to the distribution network OCS system based on the fixed value review command. Finally, the distribution network OCS system will send the fixed value review result to the automatic warehouse adjustment system.

[0040] In order to ensure data consistency and provide reliable transmission, attention should be paid to communication protocols to standardize operations to improve debugging efficiency. Communication protocols include switching fixed value area commands and results, querying fixed value area commands and results. Some communication protocols are shown in Table 1, which is a schematic table of optional communication protocols according to an embodiment of the present invention.

[0041] Table 1

[0042]

[0043] The switching of the fixed value area is achieved by presetting multiple fixed value areas. Each area can store different fixed value devices. When the fixed value of the protection device needs to be changed, it can be directly switched to the corresponding pre-set fixed value area. The fixed value area query allows real-time viewing of the currently activated fixed value settings to ensure that the protection device operates according to the expected parameters. The specific implementation process is as follows Figure 6 shown. Figure 6 FIG. 1 is a schematic diagram of an optional interaction between a fixed value area switching and a fixed value area query process according to an embodiment of the present invention. Figure 6 As shown, first, the automatic warehouse adjustment system will send a fixed value area switching command, and the distribution network OCS system will issue a fixed value area switching preset command to the distribution terminal based on the fixed value area switching command. The distribution terminal will return the fixed value area switching result to the distribution network OCS system based on the fixed value area switching preset command. The distribution network OCS system will send the fixed value area switching result to the automatic warehouse adjustment system based on the fixed value area switching result. The automatic warehouse adjustment system will send a fixed value review command to the distribution network OCS system based on the fixed value area switching result. The distribution network OCS system will issue a fixed value modification execution command to the distribution terminal based on the fixed value review command. The distribution terminal will return the fixed value modification result to the distribution network OCS system based on the fixed value modification execution command. The distribution network OCS system will send the fixed value review result to the automatic warehouse adjustment system based on the fixed value modification result.

[0044] It should be noted that the fixed value region switching function is implemented using the Adam algorithm (based on the gradient descent algorithm). The Adam algorithm is an optimization algorithm based on the first-order gradient. The core is to calculate the first-order moment (mean of the gradient) and second-order moment (uncentered variance of the gradient) of each parameter, and use this information to adjust the learning rate. By adaptively adjusting the learning rate and bias correction, the fixed value region switching function can be effectively implemented. The Adam algorithm process is as follows Figure 7 shown. Figure 7 FIG. 1 is a schematic diagram of an optional Adam algorithm process according to an embodiment of the present invention. Figure 7 As shown, firstly, the parameters can be initialized, and then the initialized parameters can be repeatedly iterated.

[0045] Optionally, the initialization parameters include: parameter initialization and setting of Adam parameters. Parameter initialization may include: initialization of parameters such as current, voltage and time setting value, and setting of Adam parameters may include but not limited to: learning rate α, first-order moment exponential decay β1, and second-order moment exponential decay rate β2.

[0046] Optionally, repeated iterations may include: calculating gradients, updating matrices, and updating parameters. Calculating gradients may include, but are not limited to: calculating gradients for the evaluated objective function after evaluating the objective function. Wherein, evaluating the objective function may include, but are not limited to: minimizing the response time of the protection device and maximizing the sensitivity of the protection device. Calculating gradients may include, but are not limited to: evaluating the fixed parameters, calculating the objective function value, and calculating the gradient vector. Updating matrices may include, but are not limited to: updating the second-order moments after the first-order moments are updated. Wherein, updating the first-order moments may include, but are not limited to: updating the first-order moments (exponential weighted average of the gradients) according to the formula of the Adam algorithm. Updating the second-order moments may include, but are not limited to: updating the second-order moments (exponential weighted average of the squared gradients) according to the formula of the Adam algorithm. Updating parameters may include, but are not limited to: calculating the learning rate adjustment factor and then updating the parameters. Calculating the learning rate adjustment factor may include, but are not limited to: using the corrected first-order moments and second-order moments to calculate the learning rate adjustment factor. Updating parameters may include, but are not limited to: updating the fixed parameters according to the learning rate adjustment factor and the gradient vector, and gradually optimizing the performance of the customized area.

[0047] After the warehouse adjustment system modifies the fixed value parameters according to the actual situation, in order to ensure that the modified equipment parameters meet the requirements, simulation verification is required to ensure the safe and stable operation of the distribution network OCS. Select simulation software for simulation verification: first build a power grid model, including a network model including transformers, transmission lines, etc.; then input the equipment parameters that have been modified by the fixed value into the corresponding model, such as protection fixed value, control fixed value, etc.; finally, perform a simulation test. If the modified fixed value satisfies the system to return to a stable state, it means that the indicator meets the expected requirements. If the system does not return to a stable state, it is necessary to return to the model for further analysis and adjustment until a better solution is found. After finding the best solution, you can return to the warehouse adjustment system to modify the fixed value parameters.

[0048] The functions of switch remote control mainly include: the "remote control operation command" sent by the debugger to the distribution network OCS system contains the terminal IP address information to ensure that the command can be accurately delivered to the designated terminal device. The distribution network OCS system first caches the received remote control operation command, and then the operator manually reviews and confirms it; after the remote control operation is completed, the distribution network OCS system will forward the remote control preset and execution results back to the debugger; the debugger is also responsible for receiving switch position change signals, which reflect the actual opening and closing status of the switch. By comparing the remote control operation command and the switch position change signal, the correctness and effectiveness of the remote control operation can be verified. If it is found that the remote control operation result is inconsistent with expectations, the debugger can intervene by alarming or notifying the operator to correct the erroneous operation in time to ensure the normal operation and safety of the system. The specific implementation process is as follows: Figure 8 shown. Figure 8FIG. 1 is an interactive schematic diagram of an optional switch remote control process according to an embodiment of the present invention. Figure 8 As shown, first, the automatic warehouse adjustment system will send a remote control operation command to the distribution network OCS system. The distribution network OCS system will cache the command and send it to the distribution terminal. After manual review and confirmation, the distribution terminal will return the remote control preset and execution results to the distribution network OCS system. The distribution network OCS system will send the remote control preset and execution results to the automatic warehouse adjustment system. At the same time, the distribution network OCS system will receive the switch change signal sent by the distribution terminal and send the switch change signal to the automatic warehouse adjustment system.

[0049] The safety check function is an important safety measure in the warehouse adjustment system. It ensures the accuracy and safety of system operation through multiple verification and audit mechanisms. The functions include: after the debugger is connected to the distribution network OCS system, when requesting to check the point table, the distribution network OCS system sends the telesignaling, telemetry and four-telemetry point table to the debugger, ensuring the correctness and completeness of the point table used. The check of the fixed value template is added during the point table check process to further ensure the accuracy of the configuration parameters; when the debugger sends parameter modification, fixed value area switching, and remote control commands, the terminal IP address information will be attached. After receiving the command, the distribution network OCS system will compare the attached IP address information with the IP address information in the terminal description library. If inconsistency is found, the command will be locked; all parameter modification, fixed value area switching, and remote control commands from the debugger need to be manually reviewed before execution, and only commands that have been reviewed and confirmed to be correct will be executed. Through multiple verification and audit mechanisms, the safety check function effectively prevents system failures and safety accidents caused by misoperation or illegal operation.

[0050] According to the implementation of the above technical solutions, the present invention improves the traditional warehouse adjustment technology through intelligent and automated technology to realize automatic debugging of distribution automation terminals. The study first deeply analyzed the various links of traditional warehouse adjustment technology and mastered its functions and operation steps in detail; then, in view of the limitations of these technologies in terms of operating efficiency, accuracy and manual dependence, the overall framework of the intelligent warehouse adjustment method of the new distribution network OCS terminal remote monitoring technology was designed. This framework covers the structure and function realization of warehouse adjustment equipment and distribution network OCS terminals, with the aim of overcoming the shortcomings of traditional technology through intelligent means; after the overall framework is determined, it is further subdivided into the realization of each specific function, such as the modification and reading of fixed value parameters, the switching of fixed value areas, etc. The realization of these functions relies on advanced remote monitoring technology, automatic debugging algorithms and data analysis technology. Advanced data processing technologies such as the Adam algorithm are also introduced to improve the decision-making intelligence and response speed of the system. In addition, the present invention also attaches importance to safety and accuracy in actual operation, and introduces a safety verification function to ensure that each step of operation will not threaten the stability of the entire system. Through this series of technical integration and innovation, an integrated method is finally formed, which significantly improves the process efficiency of the distribution automation system in operation preparation and performance verification.

Secondly, automatic monitoring and management through the master station module reduces manual intervention, improves the operating efficiency of the system, and achieves the purpose of improving the operating performance of the distribution automation system, thereby achieving the technical effect that the distribution automation system can operate with higher operating performance, thereby solving the technical problem of low operating performance of the distribution automation system in the related technology.

Fig. 9 As shown, first, the traditional warehouse adjustment technology analysis will be carried out, then the distribution network OCS system and automatic warehouse adjustment system can be designed, and finally the function design of the warehouse adjustment system can be carried out.

[0063] Among them, the steps of traditional warehouse adjustment technology analysis include: powering on the equipment (connecting the terminal equipment to the power supply), connecting the tester (connecting the relay protection instrument to the terminal), increasing the test volume (checking the response of the terminal equipment), data verification (comparing the preset parameters), communication detection and result judgment. However, the shortcomings of traditional warehouse adjustment technology include: heavy reliance on manual operation, which will lead to time-consuming and inefficient testing, and it is easy to introduce errors, affecting the test accuracy. Once the test plan is set, it is cumbersome to change and is not suitable for rapidly changing test needs. Manual operation may bring safety risks, especially in high voltage environments.

[0064] Among them, the design of the distribution network OCS system and the automatic warehouse dispatching system includes: the distribution network OCS system, the warehouse dispatching system, and the integration of the distribution network OCS system and the warehouse dispatching system. The distribution network OCS system includes: fault detection and processing, automatic positioning and isolation, rapid power restoration in non-fault areas, and planned power outage management. The warehouse dispatching system includes: master station security access module, master station module, and warehouse module. The integration of the distribution network OCS system and the warehouse dispatching system includes: real-time data exchange, mutual coordination when power grid faults are detected, and automated testing and acceptance.

[0065] Among them, the functional design of the warehouse adjustment system includes: fixed value parameter modification, fixed value parameter review, customized area switching, customized area query, switch remote control and safety verification. Fixed value parameter modification includes: allowing the operator to remotely configure and adjust the parameters of the equipment. Fixed value parameter review is used to view and confirm the current status of equipment parameters in real time. Customized area switching presets multiple fixed value areas and stores them in different customized devices, changes the timing of the protection device, and directly switches to the corresponding pre-set fixed value area. Customized area query allows real-time viewing of the currently activated fixed value device to ensure that the protection device operates according to the expected parameters. Switch remote control is used to send remote control operation instructions to the distribution network OCS system. Safety verification is used to check the point meter to ensure the stability and safety of system operation.

By adaptively adjusting and verifying the access of different types of distribution automation terminals, the efficiency and accuracy of the debugging process are significantly improved, which is conducive to improving the stability of the power network.

[0067] The research of the present invention aims to improve multiple links of traditional warehouse adjustment technology, so as to realize one-key automatic closed-loop debugging of distribution automation terminal. The research first deeply analyzed the various links of traditional warehouse adjustment technology, and mastered its functions and operation steps in detail; then, in view of the limitations of these technologies in terms of operating efficiency, accuracy and manual dependence, the overall framework of the intelligent warehouse adjustment method of the new distribution network OCS terminal remote monitoring technology was designed. This framework covers the structure and function realization of warehouse adjustment equipment and distribution network OCS system, with the aim of overcoming the shortcomings of traditional technology through intelligent means; after the overall framework is determined, it is further subdivided into the realization of each specific function, such as the modification and reading of fixed value parameters, the switching of fixed value areas, etc. The realization of these functions relies on advanced remote monitoring technology, automatic debugging algorithm and data analysis technology. Advanced data processing technologies such as Adam (based on gradient descent) optimization algorithm are also introduced to improve the decision-making intelligence and response speed of the system. In addition, the present invention also attaches importance to safety and accuracy in actual operation, and introduces a safety verification function to ensure that each step of operation will not threaten the stability of the entire system. Through this series of technological integration and innovation, an integrated approach was eventually formed, which significantly improved the process efficiency of distribution automation systems in operation preparation and performance verification.
