Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and more specifically, to a method and system for standardizing the downloading and rolling back of relay protection device configuration files based on SCD parsing. Background Art

[0002] With the continuous improvement of the digital and intelligent levels of power systems, relay protection devices, as key equipment for the safe and stable operation of power grids, the accuracy and standardization of their configuration files play a decisive role in relay protection logic execution, communication interaction, and fault handling. Especially in the context of the widespread application of the IEC 61850 standard, the configuration file structure of relay protection devices tends to be complex, covering multi-layer nested information such as logical devices (LDs), logical nodes (LNs), data objects (DOs), and data attributes (DAs), and needs to support cross-vendor communication protocols and multi-model device adaptation, bringing many challenges to the generation, downloading, and maintenance of configurations.

[0003] In addition, during the configuration deployment process of relay protection devices, key links such as the selection of configuration downloading mode, verification of device capability adaptability, verification of parameter legality, and security encapsulation of configurations need to be considered, and recognizable rollback anchor points should be automatically generated after the configuration deployment is completed to support subsequent fault handling or configuration rollback operations. Especially in the rollback scenario, the system should have the ability to quickly restore to the historical stable configuration version, so as to ensure that the device can quickly return to the normal operating state after a configuration anomaly occurs.

[0004] For example, the method and system for automatically generating interval protection configuration model data from SCD files disclosed in the invention patent with the publication number of CN118279086B, which relates to the field of power technologies, includes: parsing the SCD file, obtaining device data based on the SCD file and constructing a service model; generating virtual terminal objects and virtual circuit objects according to the device model data; generating an interoperability relationship object according to the virtual circuit object, and generating an interval protection configuration object according to the interoperability relationship object. By parsing the SCD file and constructing a service model with interval protection configuration as the core, the present invention significantly improves the understanding and operation efficiency of relay protection professionals for SCD files. By automatically processing the SCD file, it reduces the time of manual configuration and the probability of errors, improves the configuration efficiency and accuracy, and by converting the SCD file into interval protection configuration model data, it enables relay protection professionals to more intuitively understand the content of the SCD file, facilitating review and comparison.

[0005] For example, a method for generating a secondary circuit configuration file of a site-based protection device without SCD configuration disclosed in the invention patent with the publication number of CN109509239A. In the substation system configuration file, there is a lack of technical control means, and there is a risk of incorrect protection operation caused by configuration file errors. To solve the above problems, it is necessary to establish a relay protection secondary circuit that does not rely on SCD file configuration and realize configuration-free process layer configuration. By defining a virtual terminal connection template to maximize the virtual terminal connection relationship between the receiving device and the sending device, the template file does not change with the project. According to different engineering scenarios, only the relationship file between devices needs to be defined and sent to the device. The device generates a process layer configuration file related to the project according to the pre-configured template and the device connection relationship downloaded by the project. The management unit automatically generates the CRC of each device's process file according to the device connection relationship and compares it with the CRC sent by the device to achieve closed-loop verification.

[0006] In the above disclosed technical solution, there are at least the following technical problems: Before traditional deployment, only syntax-level verification is mostly carried out, lacking systematic verification of the logical dependencies between configuration fields, device capability boundaries, and deployment risks. In view of the above problems, the present invention proposes a solution. Summary of the Invention

[0007] In order to overcome the above defects of the prior art, an embodiment of the present invention provides a method for standardized downloading and fallback of a relay protection device configuration file based on SCD parsing.

[0020] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1, Figure 1 A method for standardized downloading and rollback of a relay protection device configuration file based on SCD parsing according to the present invention is provided, including the following steps: S1, obtain and parse the file of the target substation, and extract the first data of the target relay protection device from the parsed file, where the first data includes logical devices, logical nodes, communication parameters, and configuration information.

[0022] In this embodiment, obtaining and parsing the file of the target substation is specifically as follows: The system automatically obtains the SCD file of the target substation from the dispatching automation platform or the configuration management system and performs integrity checks, where the integrity checks include: (1) verifying whether the basic format structure of the SCD file conforms to the IEC 61850 standard; (2) extracting and verifying the compatibility of the namespace, version number, and the deployed parser; (3) generating a file fingerprint (such as an SHA256 hash value) to prevent tampering and support version traceability; The system performs structure parsing on the SCD file through an embedded XML parsing module or an IEC 61850 protocol-compatible parsing tool, specifically including: First, the system locates the <ied>Nodes, by matching IED names, function descriptions, or device identifiers, screen out IED entries corresponding to the target relay protection device; Then, parse the logical device information under the IED node, including logical device identifier (LD name), corresponding function blocks, primary equipment loop identifier or voltage level, etc.; The system extracts multiple logical nodes (Logical Node) defined in each logical device, identifies the types of each logical node (such as PTOC represents overcurrent protection, PDIF represents differential protection, etc.), instance numbers (LN instance numbers), and their function descriptions; Finally, further read the data objects (Data Object, DO) and their data attributes (Data Attribute, DA) contained under each logical node, and parse their hierarchical relationships and attribute contents in the data model to provide basic data support for subsequent parameter comparison and configuration item mapping; Obtain the first data associated with the relay protection device according to the parsed SCD file, and the first data includes logical devices, logical nodes, communication parameters, and configuration information.

[0023] S2, perform semantic mapping on the first data and the configuration template preset by the relay protection device manufacturer to generate an initial configuration file.

[0024] In this embodiment, performing semantic mapping on the first data and the configuration template preset by the relay protection device manufacturer to generate an initial configuration file is as follows: The system loads the configuration template preset by the corresponding manufacturer according to the model and communication protocol of the target relay protection device. The template is an ICD, CID, or manufacturer-customized format file, which contains structure definitions such as logical devices, logical nodes, and communication parameters; Perform semantic matching according to the first data and the manufacturer template, and the matching rules are as follows: For logical devices (LD), map to the device section in the template based on device identifier, function domain, and voltage level; For logical nodes (LN), fill the corresponding paragraphs in the template based on type identifiers (such as PTOC, PDIF) and instance numbers; For communication parameters (such as AP, IP, MAC, etc.), compare the network structure and fill it into the communication structure; For configuration information (such as GOOSE, report blocks, data sets), perform corresponding filling based on field names and data model hierarchies; Perform semantic mapping on the semantically matched content. For example, match the logical device with the device segment in the template, map the logical node to the template LN structure according to its type and instance number, correspond the communication parameters to the template communication topology fields, and map and fill the corresponding fields of the configuration information (such as data set, report control block, GOOSE control block) structure; According to the mapping relationship, automatically fill, replace, or supplement relevant fields in the manufacturer template to generate an initial configuration template. For cases where the fields can be directly corresponded, the system preferentially uses the one-to-one mapping method to achieve automatic filling. If there are missing fields or inconsistent structure granularities, they are recorded as "semantic fields to be parsed" and temporarily stored for further processing; Based on the rule engine, reason and automatically complete the semantic fields to be parsed. Through this reasoning mechanism, the system can extend the traditional method that only supports standard field mapping to an intelligent configuration matching method with the ability to adapt to cross-vendor and unstructured data, specifically including: If the field names are inconsistent, the system calls the semantic similarity model to perform similarity matching between the fields to be parsed and the known fields in the semantic knowledge graph, so as to identify equivalent fields or approximate fields and achieve unified mapping of field names; If there are granularity differences in the structure hierarchy, call the predefined structure reconstruction rule library to achieve granularity conversion and hierarchical reorganization through rule driving to ensure the consistency of fields in the structure hierarchy; If there are multiple candidate fields in the matching result, combine the context semantic information and configuration template constraints to perform comprehensive scoring and select the optimal matching field; If it is a manufacturer's private field, the semantic recognition module automatically identifies the manufacturer to which the field belongs and calls the corresponding private field parsing rules to complete the parsing and supplementation of specific configuration segments; After the system completes the configuration file filling and semantic supplementation process, it further performs structure compatibility scoring and difference warning analysis on the generated initial configuration file to ensure the correctness and deployment feasibility of the configuration result. Specifically, it includes: Calculate the field mapping integrity score (the number of actually matched fields / the total number of fields to be configured); Check the integrity of the control block (whether there are isolated or disconnected items in the report block, data set, GOOSE link, etc.); Compare whether the communication topology structure is consistent with the original SCD file and detect whether there are communication disconnections or redundant configurations; If the scoring result is lower than the system-set threshold (such as 85%), the system will automatically generate a structure difference analysis report and mark the key difference fields and their possible impacts for the operation and maintenance personnel to review or the system to automatically repair; After completing semantic inference completion and structural consistency evaluation, the system outputs the final configuration content as a configuration file that conforms to the specifications of the target relay protection device manufacturer. The configuration file can be in CID, ICD, or other compatible formats, and is accompanied by a summary information file, including: the number of logical nodes, the number of control blocks, communication port configuration, configuration mapping log, etc., for manual review and archival storage.

[0025] Furthermore, through the above steps, the present invention realizes the extraction from the SCD structure, the mapping to the basic template, and then the intelligent completion driven by the semantic graph, and finally forms a standardized and highly compatible configuration file, breaking through the problems of manual adaptation, format limitation, and difficult cross-vendor migration in the existing methods, and having significant automation and engineering application value.

[0026] The specific formula for differential warning analysis is as follows:

[0027] In the formula: is the differential warning index, is the number of fields that are structurally incompatible, is the field that fails semantic mapping or completion.

[0028] S3. Download the initial configuration file to the target relay protection device and obtain the configuration rollback anchor point.

[0029] In this embodiment, downloading the initial configuration file to the target relay protection device and obtaining the configuration rollback anchor point are as follows: Establish a wired or wireless communication channel with the target relay protection device, and obtain device capability information through the IEC 61850 MMS service or the manufacturer's proprietary protocol, including model identification, firmware version, supported function modules, control block capacity, and current configuration status, etc.; Semantically match the device capability information with the content of the initial configuration file to be deployed, and automatically select an appropriate configuration download mode. The download mode includes but is not limited to full download, incremental update, or functional segment loading. This matching process ensures that the structure of the configuration file is highly compatible with the device support capabilities and avoids loading failures; Before the configuration is issued, the system verifies the initial configuration file, including field integrity, structural consistency, and logical conflict detection. At the same time, it calculates the configuration summary information and generates a digital signature. The system encapsulates the configuration file together with the version identifier, verification summary, and unique token to form a secure configuration instruction; Through the established communication channel, using the IEC 61850 MMS protocol or the manufacturer's private protocol, the encapsulated configuration instructions are transmitted to the target relay protection device in batches. During the process, the system monitors the sending status in real time, including data frame integrity, transmission rate, abnormal response, etc., and supports breakpoint resumption and abnormal retry mechanisms; After receiving the configuration, the target device performs local parsing and parameter loading operations. The system extracts the configuration loading results from the data returned by the device, including key information such as the activation status of logical nodes, the configuration results of control blocks, the report enabling status, and the configuration version number; The system reads the actual running configuration content that has been activated on the target device through standard read commands or protocol parsers, compares the obtained running status with the initial configuration file for field-level consistency analysis, evaluates the loading effect, identifies different fields or unimplemented parameters, and generates a difference analysis list and a configuration consistency score; According to the consistency comparison results, archive the detailed data of this configuration process, including the target device identifier, configuration content, deployment time, loading results, and comparison reports, synchronously generate a configuration deployment version identifier, and establish a configuration rollback anchor point to support subsequent exception recovery or version rollback operations.

[0030] The specific formula for the configuration consistency score is as follows:

[0031] In the formula: is the configuration consistency score. The closer this score is to 1, the more consistent the actual running configuration is with the expected configuration. is the number of fields with inconsistent values. is the number of fields that are not loaded or have parsing failures. is the number of unactivated logical nodes or function blocks. is the total number of fields in the initial configuration file.

[0032] In this embodiment, the system verifies the initial configuration file as follows: Based on the embedded IEC 61850 standard parsing module, the system reads the structure of the initial configuration file and performs the following two-level nested parsing: The first level: Identify and verify the integrity of the structural levels such as IED, logical device (LD), and logical node (LN); The second level: Perform syntax legality and value range verification on the data objects (DO) and data attributes (DA) under each logical node to ensure two-dimensional consistency of the structure and fields; After completing the basic structure analysis, through the pre-constructed semantic knowledge graph of relay protection configuration, identify the association logic, enabling dependencies, and mutual exclusion conditions between configuration fields, and determine whether there are logical misconfigurations or illegal combinations. For example, determine whether a necessary event trigger mechanism is missing when a certain function LN node is enabled; analyze whether there are coordination time logic conflicts between multiple protection components; automatically identify the risk of function mapping failure caused by manufacturer differences; Obtain the device capability description of the target relay protection device (such as the supported LN types, maximum configuration block length, supported protocol types, etc.), and perform one-to-one matching with the initial configuration file to determine whether the current configuration exceeds the device capability boundary. If incompatibilities are found, the system will provide compatibility prompts and suggest adjusting the configuration or switching the deployment strategy; If the current configuration is for an upgrade deployment or a reload operation, the system reads the current running configuration version of the device and compares the field differences with the initial configuration file. The specific operations are as follows: generate a difference mapping table for added, changed, and deleted fields; mark the path where the field is located and the change type; start a compatibility impact analysis for keyword field changes; Based on the field difference comparison, obtain the deployment risk data, where the deployment risk data includes field integrity, structure matching degree, logic conflict factor, and historical deployment success rate, and output a deployment risk score based on the weighted method according to the deployment risk data; Based on the deployment risk score, the system generates a unique configuration anchor point identifier and conducts a pre-deployment simulation rollback test to verify the feasibility and stability of configuration loading.

[0033] S4, obtain the configuration application data transmitted back by the relay protection device, and combine it with the configuration rollback anchor point to perform the rollback operation of the configuration file.

[0034] In this embodiment, obtain the configuration application data transmitted back by the relay protection device, and combine it with the configuration rollback anchor point to perform the rollback operation of the configuration file, as follows: The system receives the configuration application data transmitted back by the target relay protection device through the communication interface. This data includes the current configuration version number, configuration loading status, activated field information, and abnormal alarm information; Based on the transmitted abnormal information, the system calls the deployment history database to retrieve the rollback anchor point and historical configuration version corresponding to the current configuration; According to the selected rollback anchor point, extract the corresponding rollback configuration file from the historical version library; Download the rollback configuration file to the target relay protection device through the IEC 61850 MMS protocol or the manufacturer's proprietary communication protocol; After the lower installation is completed, the system reads the current running configuration from the device and performs a field-level comparison with the rollback configuration file to confirm whether the configuration has been successfully rolled back. If the rollback is successful, the system updates the configuration version information, generates a rollback log and an event record, and archives the rollback process. If the rollback fails, the system triggers an exception handling mechanism, notifies the operation and maintenance personnel, and recommends manual intervention.
