[0002] In the field of power distribution automation, the calibration of distribution terminals is crucial for ensuring stable grid operation. Existing calibration methods primarily rely on manual phone checks and on-site testing. This approach is not only inefficient but also susceptible to human influence, resulting in inaccurate and unreliable calibration results. With the increasing number of distribution terminal devices and their increasing intelligence, traditional calibration methods are no longer able to meet the efficient and accurate calibration requirements of modern power systems.

[0003] While some automated verification tools are currently in use, most methods are inadequate when simulating the operating conditions of distribution terminals. They are unable to accurately simulate the complex operating conditions encountered in actual operation, particularly transient faults and abnormal operating conditions. This leads to discrepancies between verification results and actual operation. Furthermore, existing verification methods are incomplete in testing communication consistency and data transmission performance, failing to fully account for the diversity of communication protocols and the security risks involved in data transmission.

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Figure 1 Schematic diagram of the method of the present invention. DETAILED DESCRIPTION

[0042] The terms "first", "second", "third", "fourth", etc. (if any) in the specification of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "corresponding to" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0043] Example 1

[0044] The implementation method in this embodiment can be implemented in the system, can be implemented in the server, and can also be implemented in the terminal, without specific limitation. The following describes the method in this application from the perspective of system implementation. As shown in the figure, a distribution terminal calibration method based on high-precision analog output includes the following steps:

[0045] Obtaining hardware information and external response event information of the power distribution terminal to be inspected, and building an event simulation output model based on the hardware information and external response event information;

[0046] Obtain verification requirements, configure analog output parameters through simulation output model, and simulate the actual operating conditions of the equipment to be tested;

[0047] When the equipment to be tested is simulating its operating conditions, communication consistency verification and data transmission optimization, as well as security authentication and wireless verification, are performed;

[0048] Obtain verification results for communication consistency verification, data transmission optimization, security authentication, and wireless verification and generate standardized reports.

[0049] First, hardware information and external response event information for the power distribution terminal are obtained to construct an event simulation output model that reflects the terminal's characteristics. This model is then used to configure analog output parameters based on verification requirements to simulate realistic operating conditions. During the simulation, two key verification steps—communication consistency verification and data transmission optimization, as well as security authentication and wireless verification—are simultaneously performed to ensure stable communication and efficient and secure data transmission during actual terminal operation. Finally, all verification results are collected and a standardized report is generated to comprehensively evaluate the performance and functionality of the power distribution terminal.

[0050] Example 2

[0051] This embodiment differs from the first embodiment in that the process of constructing an event simulation output model based on hardware information and external response event information includes the following steps:

[0052] Obtain hardware information to determine the equipment type, signal output range, communication interface and protocol hardware parameters of the power distribution terminal;

[0053] Obtain external response event information and extract characteristic events of distribution terminals under different operating conditions;

[0054] According to hardware parameters and characteristic events, a preliminary event simulation model is constructed through discrete event simulation algorithm.

[0055] By analyzing the hardware information of the power distribution terminal, we accurately determine its hardware parameters, such as device type and signal output range, thus providing the hardware-level foundational data for model construction. Next, we extract characteristic events of the terminal under different operating conditions from external response event information. These characteristic events can reflect the terminal's behavior and response characteristics in actual operation. Then, by combining these hardware parameters with the characteristic events and applying a discrete event simulation algorithm, we construct an event simulation model that preliminarily reflects the terminal's operational characteristics, providing a more accurate model foundation for subsequent verification processes.

[0056] Example 3

[0057] This embodiment differs from the second embodiment in that the construction of a preliminary event simulation model using a discrete event simulation algorithm includes the following steps:

[0058] Set and define signal output events, fault events and control events, and set the priority to: fault events > control events > signal output events;

[0059] Manage the event queue through a small top heap, sort by event timestamp and priority, and use Next Event TimeAdvance and adaptive time step strategies to advance time;

[0060] Generate normal waveforms and transient waveforms according to hardware parameters and process signal output events;

[0061] According to the triggered fault event, replace the waveform and judge the protection logic response to handle the fault event;

[0062] Generate corresponding events and return status data according to the simulated master station instructions and wireless verification instructions to process control events;

[0063] According to the hardware measured data, the interpolation algorithm parameters of the simulation model are reversely adjusted.

[0064] Detailed event types are defined, including signal output events, fault events, and control events, with clear priorities to ensure that critical events are prioritized during model execution. Next, a mini-heap is used to manage the event queue, sorting events by timestamp and priority. Time is advanced using Next Event Time Advance and an adaptive time step strategy, making the simulation more efficient and accurately aligned with actual operating conditions. In signal output event processing, normal and transient waveforms are generated based on hardware parameters to simulate the terminal's signal output under different operating conditions. For fault event processing, when a fault event is detected, the normal waveform is immediately replaced with a transient model, and the protection logic is quickly determined to verify the proper functioning of the terminal's protection functions. In control event processing, master station commands and wireless verification commands are simulated to generate corresponding events and promptly return status data, ensuring the effective execution of control commands and the reliability of wireless verification. Finally, the interpolation algorithm parameters of the simulation model are adjusted using actual hardware measurement data to further improve the model's accuracy and reliability, ensuring that the model more realistically reflects the actual operation of the distribution terminal.

[0065] Example 4

[0066] The difference between this embodiment and embodiment three is that the hardware information includes the device model, interface type, communication protocol and signal output range of the distribution terminal, and the external response event information includes the action signal, fault indication and communication feedback of the distribution terminal under different operating conditions.

[0067] Hardware information includes key parameters such as the distribution terminal's device model, interface type, communication protocol, and signal output range. These parameters provide detailed hardware foundational data for building accurate event simulation models. External response event information includes the distribution terminal's action signals, fault indications, and communication feedback under different operating conditions. By analyzing this information, characteristic events can be extracted, providing rich, real-world operational scenario data for model construction. This allows the constructed event simulation output model to more closely align with the actual operating characteristics of the distribution terminal, providing a more accurate simulation foundation for subsequent verification work.

[0068] Example 5

[0069] This embodiment differs from the fourth embodiment in that the communication consistency check and data transmission optimization include monitoring the communication data packets between the terminal and the master station, verifying the integrity and accuracy of the data, and using data compression and differential coding technology to reduce the communication volume.

[0070] During the verification process, communication data packets between the distribution terminal and the master station are monitored and parsed to verify their integrity and accuracy, ensuring effective communication between the two parties. Furthermore, to improve data transmission efficiency, data compression technology is employed to compress the data, and differential encoding technology is employed to transmit only the changing portion of the data, reducing unnecessary data transmission and thus bandwidth usage. These optimization measures improve communication efficiency while maintaining communication quality, ensuring smooth verification and timely transmission of verification data.

[0071] Example 6

[0072] This embodiment differs from the fifth embodiment in that the security authentication and wireless verification include establishing an encrypted communication link and using an identity authentication mechanism to ensure the legitimacy of the verification instruction and the security of data transmission.

[0073] During the verification process, an encrypted communication link is first established, and the transmitted data is encrypted using encryption technology to prevent theft or tampering during transmission. Simultaneously, an identity authentication mechanism verifies the legitimacy of verification instructions and the security of data transmission, ensuring that only legitimate instructions can be executed and that the integrity and confidentiality of data are maintained during transmission. These security measures effectively ensure the security of the verification process, prevent unauthorized access and malicious attacks, and provide a safe and reliable communication environment for verification of distribution terminals.

[0074] Example 7

[0075] The difference between this embodiment and embodiment six is that the calibration results include the response accuracy of the distribution terminal to analog quantities, the correctness of the execution of logical functions, and the stability of communication, and the standardized report includes test time, test items, test results, and improvement suggestions.

[0076] Calibration results primarily cover key aspects such as the distribution terminal's response accuracy to analog quantities, the correctness of logical function execution, and communication stability. A comprehensive assessment of these indicators provides a comprehensive understanding of the distribution terminal's performance and functional deficiencies. A standardized report is then generated, detailing test time, test items, test results, and improvement suggestions. This structured report not only helps calibrators quickly understand the calibration status but also provides clear direction and guidance for subsequent equipment improvements and maintenance, thereby enhancing the overall performance and reliability of the distribution terminal.
