DETAILED DESCRIPTION

[0018] In order to clearly illustrate the technical features of this solution, the present invention is described in detail below through specific implementation methods and in conjunction with the accompanying drawings. The disclosure below provides many different embodiments or examples for realizing different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. In addition, the present invention may repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed. It should be noted that the components illustrated in the accompanying drawings are not necessarily drawn to scale. The present invention omits descriptions of well-known components and processing technologies and processes to avoid unnecessary limitations on the present invention.

[0019] Example 1 Embodiment 1 of the present invention proposes an intensive platform for relay protection debugging of a power system, which is used to solve the technical problems existing in the power system relay protection debugging equipment in the prior art. Figure 1 The hardware framework of a power system relay protection debugging centralized platform proposed in Example 1 of the present invention includes: a test control unit, a switch IO unit, an interface unit, and a model mapping unit; A test control unit is used to perform relay protection unit function debugging and relay protection debugging according to the received test instructions and prefabricated test templates and generate corresponding control signals; The switch quantity IO unit is used to obtain the switch quantity signal required for relay protection unit function debugging and send it to the test control unit; Interface unit, used to obtain substation operation data required for relay protection commissioning and send it to the test control unit; The model mapping unit is used to associate the device model information with the virtual terminals of the actual device according to the device model information in the substation configuration file when the test control unit performs a test.

[0020] In this application, the test control unit is the core of the entire platform, responsible for coordinating the work of each module and realizing the automated control of the test process. The test control unit receives test instructions from the debugging management unit, generates corresponding control signals according to the instructions, and controls the operation of other modules. For example, when debugging the relay protection unit function, the test control unit will control the switch IO unit to output the corresponding switch signal and control the power amplifier module to output the analog signal according to the test steps in the debugging template. At the same time, it monitors the action of the protection device and feeds back the monitoring results to the debugging management unit.

[0021] When debugging the relay protection unit function, the test control unit controls the switch quantity IO unit to output switch quantity signals, the power amplifier unit to output analog quantity signals, and monitors the operation of the substation protection device.

[0022] When debugging the relay protection, the test control unit obtains the simulated circuit breaker opening and closing signals, the knife switch position signals, and the light-on quantity signals of the acquisition protection device to debug the relay protection.

[0023] In this application, the binary I / O unit is used to implement the input and output of digital signals. During relay protection commissioning, various binary signals are required to simulate actual operational state changes, such as circuit breaker opening and closing signals and switch position signals. Furthermore, it is necessary to collect binary signals output by protection devices, such as protection action signals and alarm signals. The binary I / O module offers high speed and reliability, meeting the digital signal processing requirements of relay protection commissioning. It uses optoelectronic isolation technology to isolate external signals from internal circuits, improving the system's anti-interference capabilities.

[0024] In this application, the interface unit includes the SV interface module, the GOOSE interface module, and the CMS / MMS interface module. The SV interface module is used to input and output substation sampled value signals; the GOOSE interface module is used to transmit and receive general object-oriented substation event signals; and the CMS / MMS interface module is used to communicate with the substation automation system.

[0025] The SV interface module is used to input and output sampled value (SV) signals. In smart substations, protection devices receive sampled value signals from merging units via the SV interface to perform protection operations. During commissioning, it is necessary to simulate merging unit transmission of SV signals to test the sampling accuracy and protection logic of the protection device. The SV interface module supports standard protocols such as IEC61850-9-2 and can accurately generate and interpret SV signals. It can flexibly configure SV signal parameters such as amplitude, phase, and frequency based on test requirements, enabling comprehensive testing of protection devices.

[0026] The GOOSE interface module is used to transmit and receive Generic Object Oriented Substation Event (GOOSE) signals. GOOSE signals are primarily used for fast communication between protection devices and between protection devices and intelligent terminals, transmitting important information such as switching state changes and protection action commands. The GOOSE interface module enables fast and reliable transmission and reception of GOOSE messages, ensuring timely signal transmission and processing during debugging. It supports both multicast and unicast communication modes to meet diverse communication needs. The module also features message filtering and parsing capabilities, enabling it to filter and analyze received GOOSE messages to extract useful information.

[0027] The CMS / MMS interface module enables communication with the substation automation system (SAS). It supports the Substation Communication Network and System (CMS) and Manufacturing Message Specification (MMS) protocols. Through this interface module, the test system can exchange data with the SAS, obtaining real-time operational data such as device status and measurements. It can also send test commands and results to the SAS. This allows the test system to better integrate into the overall substation operating environment and enable online testing and debugging of relay protection equipment.

[0028] For example, when conducting telecontrol point-to-point testing, the test system can communicate with the telecontrol device through the CMS / MMS interface module to verify the accuracy and reliability of the telecontrol signal.

[0029] The platform also includes: power amplifier module, clock synchronization unit, test template management unit, test evaluation unit, test report generation unit, etc.

[0030] The power amplifier module is primarily responsible for amplifying the analog signal output by the test host to meet the input signal power requirements of the protection device. During relay protection commissioning, various analog signals, such as current and voltage, need to be applied to the protection device to test its operating characteristics. The power amplifier module amplifies low-power analog signals to sufficient power levels to ensure proper operation of the protection device. It typically utilizes linear power amplification technology, offering high power gain and low distortion, ensuring output signal quality.

[0031] The clock synchronization unit includes a time synchronization interface module and a clock synchronization module.

[0032] The timing interface module synchronizes the test system with an external clock source, ensuring time consistency across modules during testing. Time synchronization is crucial during relay protection commissioning, especially when testing protection operation timing. The timing interface module supports multiple timing methods, including GPS, Beidou, and IRIG-B, allowing you to select the appropriate method based on your needs. By synchronizing with an external clock source, the test system can precisely control the transmission and reception times of test signals, improving the accuracy of test results.

[0033] The clock synchronization module is a core component of the timing interface module, responsible for clock synchronization between modules within the test system. Using a high-precision clock signal generator and clock distribution circuitry, it precisely distributes the clock signal from an external clock source to each module, ensuring that the clock signals in each module have the same frequency and phase. The clock synchronization module utilizes advanced clock synchronization algorithms that automatically compensate for delays and drift during clock signal transmission, ensuring accurate clock synchronization. The clock synchronization module is particularly important in multi-module collaborative testing scenarios, ensuring strict time sequence for signal transmission and processing between modules, thus avoiding test errors caused by time asynchrony. The test template management unit is used to store and manage various test templates, allowing users to quickly access them during the debugging process. Test templates are pre-defined test plans based on different test items and test objectives, and contain information such as test steps, test parameters, and expected results. The test template management unit supports the creation, editing, deletion, importing, and exporting of test templates, allowing users to customize and optimize test templates based on actual needs. For example, corresponding test templates can be created for relay protection devices from different manufacturers and models to improve the targetedness and efficiency of testing. The unit also manages test template versions and records the modification history of test templates, facilitating user traceability and management.

[0034] The test evaluation unit analyzes and evaluates test results to determine whether the relay protection equipment meets design requirements and operating standards. It compares and analyzes actual test results against the expected results in the test template, generating a detailed test evaluation report. The test evaluation unit utilizes multiple evaluation algorithms and metrics to comprehensively assess the protection device's operating characteristics, sampling accuracy, and communication performance. For example, by calculating metrics such as the protection device's operating time error, sampling value error, and GOOSE message transmission delay, it determines whether the protection device's performance meets requirements. The test evaluation unit also diagnoses and analyzes any anomalies that arise during testing, providing solutions and helping users quickly identify and resolve issues. The test report generation unit is responsible for automatically generating standardized test reports based on the results of the test evaluation unit. The test report contains test items, test results, evaluation conclusions, abnormal conditions and handling suggestions, providing users with detailed test records and reference basis. The test report generation unit supports multiple report formats, such as PDF, Word, Excel, etc. Users can choose the appropriate format to generate and export reports according to their needs. At the same time, the unit can also customize the test report. Users can add or modify the content in the report according to actual needs to make the report more in line with the actual application scenario. For example, adding information such as project name, tester, test time, etc. to the report makes it easier for users to manage and archive test work.

[0035] An intensive platform for relay protection debugging of a power system proposed in Example 1 of the present invention realizes standardization of debugging processes, integration of test tools, full-cycle traceability of test data, and security management of configuration files; it integrates multiple debugging devices and tools to realize resource sharing and collaboration.

[0036] Example 2 Based on the power system relay protection debugging centralized platform proposed in Example 1 of the present invention, Example 2 of the present invention further proposes a control method for the power system relay protection debugging centralized platform. The overall process implemented by the control method includes: Based on the digital signals required by relay protection equipment, measurement and control equipment, and acquisition execution units, model the equipment in the form of equipment to form an intermediate database; Analyze the prerequisites of the test sub-items, the signal states to be applied, and the action results to be checked, select signal configuration test cases from the intermediate database, and combine them to form a complete test case; Perform relay protection unit function debugging and relay protection debugging according to the received test instructions and prefabricated test templates and generate corresponding control signals; Analyze the actual test results according to the corresponding test signals output by the test control unit to generate test evaluation results; automatically generate a standard test report according to the test control unit; And map the criteria and applied signal quantities in the configuration template with the signal definitions in the actual engineering SCD file, and read the signal definition information in the SCD file to establish a mapping relationship.

[0037] Figure 2This is a schematic diagram of the configuration automatic testing technology principle proposed in Example 2 of the present invention. Based on flexible configuration test outline template technology, debugging templates are generated through flexible editing, eliminating the need to solidify debugging templates through test instruments. This ensures that test templates can be applied to different test purposes and test scenarios. Templates can also be easily edited to adapt to differentiated needs. Through complex global information modeling and debugging template configuration, a whole-station system-level joint automatic debugging solution can be formed, including relay protection single function debugging, relay protection entire circuit debugging, telecontrol point alignment, recorder acceptance, and other functions.

[0038] The specific method is to sort out the digital signals that need to be used according to possible test items and test purposes, including CMS / MMS signals and GOOSE signals of various types of relay protection, CMS / MMS signals and GOOSE signals of measurement and control, GOOSE signals and SV signals of acquisition execution units, etc., and uniformly model them according to the form of equipment. The above signal collection forms an intermediate database with the equipment as the object.

[0039] Based on specific test items or tasks, key test requirements are outlined. For example, using a complete set of test reports as a benchmark, the prerequisites for each specific test sub-item, the signal states required, and the action results required for verification are analyzed. The corresponding test case configuration is then completed using signals from the intermediate database. This test case configuration supports sequential configuration of test sub-items and combines them into specific test tasks, ultimately forming a complete test case. These test cases are generated through flexible configuration based on the intermediate database and are not based on specific SCD file information or fixed algorithms, ensuring scalability and versatility.

[0040] The instantiation of a configuration template is to map the specific criteria and applied signal quantities in the template with the signal definitions in the actual project SCD file to form a usable instantiation template.

[0041] After the debugging template is generated through configuration, the problem of debugging use cases is solved. It is not difficult to generate debugging reports based on debugging use cases for standardized solidified debugging templates. Usually, there is a fixed data template format, and it is generated by reading fixed debugging use case result data. It is no longer applicable to debugging use cases generated through configuration.

[0042] The configuration method of the test report is flexible and editable. First, based on the debugging report form, the header, test items, and test data table are edited and generated. The results in the table support dragging and selecting the data results in the debugging template. If the above conditions are met, the original debugging report form can be restored to the maximum extent. The entire set of tests generated by the debugging template in the configuration method will not affect the test report of the original manual test, ensuring high adaptability and usability when issuing reports on test result data.

[0043] Figure 3 This is a schematic diagram of a report template generated by the configuration method proposed in Example 2 of the present invention. In the process of generating a specific report, the format of the report is generally in a table format. The rows and columns of the table can be generated on a completely blank basis. The text or the test results in the associated test template can be edited at will in the cells of the rows and columns formed. Ultimately, the format and content of the original test report can be restored. At the same time, the test results can be automatically filled in according to the judgment results during the test process to generate a debugging report with test results.

[0044] Figure 4 This is a schematic diagram of the automated testing proposed in Example 2 of the present invention. This closed-loop automated testing technology, based on configuration templates, enables instantiation and generation of test case templates and closed-loop automation of the testing process. A configuration-based test template is composed of a set of test components. Device test templates can be directly referenced as "black boxes" or used as "white boxes" to implement template addition, deletion, modification, import, and export. Finally, an actual protection device test process is generated by instantiating the protection device test template.

[0045] Based on the functional configuration of each manufacturer's protection model, a typical test case template library is established. It is connected to the station control layer network through the electrical Ethernet interface, and CMS / MMS message interaction is carried out with the IED under test. The pressure plate, set value, control word and other information of the equipment can be summoned and remotely modified. Test cases are automatically instantiated and generated to achieve one-click automatic testing of sampling accuracy, virtual terminal correctness, set value and other functions of single device and single bay equipment.

[0046] After the test is completed, the test system automatically generates a corresponding test report based on the test results in the standard format, including device information, inspection items, inspection results and judgments.

[0047] Figure 5This is a schematic diagram of the closed-loop structure of the automatic test system proposed in Example 2 of the present invention; the automatic test system software and the acceptance test host complete the functions of issuing test control commands and feeding back test results, and communicate with the relay protection device under test using the CMS / MMS communication protocol based on the IEC61850 standard to realize the functions of issuing protection device control commands and obtaining device action reports, recordings, remote signaling changes, and other information. The automatic test system software implements test task scheduling control and result judgment, and ultimately realizes fully automatic closed-loop testing.

[0048] In addition, during the execution of the control method for a power system relay protection and commissioning intensive platform proposed in Example 2 of the present invention, the substation configuration file management and control system, designed with automation, standardization, reliability, and traceability as its design principles, achieves intelligent and centralized configuration file management through technical means such as automatic verification and process control. The system comprehensively covers key functions such as automatic verification of SCD files, configuration file consistency verification, and difference comparison, significantly improving the efficiency and accuracy of configuration file management and providing strong technical support for power grid operation and maintenance.

[0049] Figure 6 This is the SCD control flow chart proposed in Example 2 of the present invention. The visualization of the SCD file extracts device information and communication topology through file parsing technology to construct logical association data between devices. After the parsing is completed, the system uses D3.js or ECharts framework to generate an interactive topology diagram, dynamically displaying device nodes and communication paths. Users can click on the device node to view detailed attribute information, such as logical functions, associated nodes, etc. The difference comparison function is based on the node hash value comparison algorithm to quickly locate the differences between file versions, and display them according to the four levels of modification, addition, deletion, and no change, and highlight the changes with colors to intuitively present the content.

[0050] The system supports displaying SCD file differences in a visual interface, offering both topology display and text comparison modes, helping users quickly review file changes. The system also generates difference analysis reports detailing the specific location and content of device changes. These reports can be exported to PDF or Excel formats, facilitating file configuration review and adjustments.

[0051] The configuration file consistency check is mainly divided into two modes: automatic mode and manual mode. In automatic mode: the system obtains the process layer CRC check code of each device through the Baoxin substation system and parses the signed-in SCD file to extract the process layer CRC check code of the corresponding device for comparison to confirm the consistency of the downloaded file. In manual mode: the operation and maintenance personnel manually upload the CID / CCD configuration files of each device. The system parses the device configuration content of the CID / CCD file and the SCD file according to standard rules, removes the meaningless parts (such as private nodes and file header information), and retains only the key configuration parameters for CRC value calculation. By comparing the calculated CRC of the CID / CCD file with the calculated CRC value of the corresponding device in the SCD file one by one, the nodes and parameter items with inconsistent configurations can be quickly located. The comparison results are presented in a verification report. The report lists the differences in detail and visually marks the difference locations, which is convenient for users to quickly identify and analyze problems.

[0052] The Renovation / Expansion Boundary Module compares the virtual circuit configurations of the two SCD files before and after the renovation / expansion to intelligently determine whether the virtual circuits of directly and indirectly associated devices have changed. This module then identifies the IEDs that require testing and provides test item prompts. The system first analyzes the virtual circuit configuration of each IED in the two SCD files and calculates a sub-CRC value for each virtual circuit.

[0053] During this comparison, the system compares the sub-CRC values ​​of directly connected IEDs in the SCD files before and after the renovation and expansion, identifying which IEDs' virtual connections have changed. It also analyzes the virtual circuit relationships between directly and indirectly connected devices to determine the extent of the virtual circuit changes. If the sub-CRC values ​​of directly and indirectly connected devices match, retesting and resimulating the drive are unnecessary. If the sub-CRC values ​​differ, retesting and resimulating the drive are necessary to ensure the reliability of the virtual circuits.

[0054] The SCD verification module comprehensively verifies the file's syntax, semantics, and logical consistency by parsing key information in the configuration file, including logical devices, communication parameters, and virtual circuit configurations. Syntax verification, based on industry standards, focuses on the integrity of the file structure and the correctness of the fields. Semantic verification focuses on the rationality of logical associations, verifying the correctness of communication paths, the closure of virtual terminal connections, and the consistency of terminal descriptions between devices, ensuring that the file content conforms to design specifications.

[0055] By introducing a virtual terminal expert library and a standard virtual circuit template library, multi-source synchronous comparison technology is used for homology verification. The expert library covers standard virtual terminal definitions for equipment from various manufacturers and supports automatic replacement of non-standard terminals. The virtual circuit template library stores standardized virtual circuit connection patterns. By matching, it verifies the virtual circuit configuration in the SCD file and promptly identifies potential problems.

[0056] Verification results are displayed by category, including syntax errors, missing loops, and virtual loop errors. The system visualizes the anomalies discovered during verification, allowing users to directly view problem nodes and obtain detailed repair suggestions, facilitating rapid location and rectification. The module also supports differentiated highlighting and error severity grading to enhance the user experience.

[0057] File control achieves efficient management of the entire life cycle of configuration files through the control of configuration files for newly built stations and renovated and expanded stations, thereby improving the standardization and intelligence of file operations. For newly built stations, users must first create ledger information before they can start the check-in operation of the configuration file; for renovated and expanded stations, the configuration file must be checked out first for modification. The system provides a check-out status indicator in the interface to intuitively indicate the file status. At the same time, the system sets a time range reminder mechanism for uploading configuration files before signing out and commissioning. If the upload is not completed within the time limit, the system will automatically trigger a reminder to ensure that the configuration work is completed on time. The system strictly manages the check-in and check-out operations of files through standardized processes to ensure the integrity and consistency of file configuration.

[0058] Historical retrieval achieves comprehensive traceability and rapid retrieval of file change records by managing configuration file operation logs and version information. The module supports multi-dimensional conditional filtering and full-text search functions to help users efficiently locate target files and their historical operation records. In terms of technical implementation, the system keeps detailed records of each file check-in, check-out, modification, and verification operation, including operation time, operating user, operation type, and specific changes to the file. Log information is stored in a structured form and archived by timeline to ensure the integrity and consistency of data queries. Users can filter by time range, file type, operating user, or specific keywords to quickly locate target records. In addition, the system integrates full-text retrieval technology (such as Elasticsearch) to support accurate searches of file content and log details, significantly improving retrieval efficiency.

[0059] The User Management module is responsible for creating, managing, and authenticating user accounts. The system supports binding users to roles and assigning permissions through roles, ensuring that users can only access functions within their authorized scope. Passwords are stored using encryption (e.g., BCrypt), and multi-factor authentication is supported to enhance account security. The module also provides login logging, including login time, IP address, and operation details, providing technical support for user behavior audits.

[0060] The Organizational Structure module manages multi-level unit information through a tree-like structure, supporting dynamic adjustment and maintenance of organizational structures. The system automatically updates organizational hierarchies through database hierarchical associations. Users can intuitively add, edit, and delete organizations through the interface, dynamically linking their subordinate user, device, and site data to support clear management of the organizational structure.

[0061] The task management module categorizes tasks into four types: new construction, technical upgrade, expansion, and configuration file changes, based on their application scenarios and objectives. New construction tasks primarily cover initial ledger creation and configuration file generation; technical upgrade tasks focus on equipment configuration changes; expansion tasks include entering new equipment into the ledger and associated configurations; and configuration file changes involve file version updates, check-in and check-out, and consistency checks. The system collects statistics and tracks each task, recording task status in real time and generating analytical reports. This helps users quickly understand task progress and execution results, supporting efficient task management.

[0062] The control method of the power system relay protection commissioning centralized platform proposed in Example 2 of the present invention can not only realize the archiving and management of engineering data, but also edit and review SCD files, further improving the efficiency and convenience of commissioning work.
