Simultaneously, it promotes the intelligentization process of substations, thereby effectively improving the operational stability and reliability of smart substations and reducing maintenance costs and potential risks caused by file configuration issues.

[0063] One embodiment of the present invention provides an SCD file management method. For details, please refer to [link / reference]. Figure 1 , Figure 1 The diagram shown is a flowchart of an SCD file management method according to one embodiment of the present invention, which includes steps S1 to S6:

[0064] S1. In response to the SCD file processing request, obtain the SCD file of the target smart substation;

[0065] S2. Parse the SCD file and extract the features of each element in the SCD file;

[0066] S3. Determine the potential impact factors of the SCD file based on the characteristics of each element;

[0067] S4. Determine the weight results of each of the potential influencing factors;

[0068] S5. Using all the weighted results, obtain the execution score of the SCD file;

[0069] S6. When the execution score is detected to meet the preset conditions, the substation control strategy that matches the SCD file is executed.

[0070] It should be noted that the SCD file acts as a "blueprint" for the entire substation's secondary system, accurately describing the configuration, connections, and communication methods of various devices within the substation. It plays a crucial role in substation control. For example, the SCD file specifies the sending and receiving parameters for messages such as GOOSE and SMV, enabling protection devices to quickly acquire fault information and implement tripping control. Measurement and control devices can accurately upload measurement data to the monitoring system. Simultaneously, the monitoring system, by parsing the SCD file, can monitor the substation equipment status in real time, remotely control the equipment, and achieve automated operation management of the substation. Existing SCD files are numerous, sometimes containing thousands of lines of text, making them difficult for personnel to read. This invention's embodiment designs the aforementioned SCD file management method, which can accurately evaluate the completeness and accuracy of SCD files, identify key factors affecting operation, and provide strong support for subsequent substation control optimization and improvement.

[0071] For preferred options, please refer to [link / reference]. Figure 2 , Figure 2 The diagram shown is a flowchart of an SCD file management method according to one embodiment of the present invention. Figure 2 First, the SCD file is parsed to extract information about each element, including IED name, communication parameters, and logical node information. Then, several potential factors affecting the standardization of the SCD file are identified, such as file structure rationality, element information completeness, data consistency, and virtual loop correctness. For each potential factor, corresponding evaluation indicators and methods are developed. For example, file structure rationality can be evaluated by checking whether the file conforms to the structural requirements of the standard specifications; element information completeness can be evaluated by calculating the proportion of missing elements to the total number of elements. Based on the established evaluation indicators and methods, the SCD file is evaluated to obtain a score for each potential factor. Finally, a multi-factor comprehensive evaluation method, such as the analytic hierarchy process (AHP), is used to determine the weight of each potential factor and calculate the SCD file execution score. Based on the execution score, a substation control strategy matching the SCD file can be implemented, thereby achieving reasonable management and control of the smart substation.

[0072] Specifically, in the above embodiments, the operation can be performed by an electronic device with computing capabilities, such as a user terminal or a server. A user can operate the user terminal to send a request for processing SCD files, or operate the user terminal to send a request for processing SCD files to the server. During operation, the user can select one or more SCD files and then click the processing button in the application to issue an SCD file processing request. Further details are omitted in this embodiment.

[0073] Since the nodes of the SCD file are organized in a tree-like hierarchical structure, the complete file consists of five main parts: Header, Substation, Communication, IED (Intelligent Device), and DataTypeTemplates. Based on XML (Extensible Markup Language) format, the SCD file of the target intelligent substation is parsed to obtain the information of each element in the file, and stored in a database for subsequent analysis and evaluation. Preferably, the method includes the following steps:

[0074] Step 1: Import the SCD file and parse the information of each node of the SCD sequentially based on the SCL language.

[0075] Step 2: Parse and identify the header node information to obtain header node features such as SCD version (Version), revision (Revision), SCD name (Id), and revision time (When). Of course, if the revision, version, and when under the Header are empty, then the last record of the History is taken, which will not be elaborated here.

[0076] Step 3: Parse and identify private node information, and obtain private node characteristics such as the site-wide CRC checksum.

[0077] Step 4: Parse and identify site information to obtain site features such as substation name (Name).

[0078] Step 5: Parse and identify communication information to obtain communication features such as subnet, MMS configuration, GSE configuration, and SMV configuration.

[0079] Step 6: Parse and identify smart device information to obtain smart device characteristics such as virtual terminal association configuration (Input).

[0080] Step 7: Parse the application model information and obtain application model features such as physical device (IED) modeling, physical port modeling, service (Server) modeling, logical device (LD) modeling, and logical node (LN) modeling.

[0081] By designing a pre-defined standard evaluation template, element features can be matched and filtered to determine the potential impact factors of the SCD file. For example, the standard evaluation template is generally associated with the following five attributes:

[0082] Document structure rationality: This includes whether the document conforms to the structural requirements of the standard specifications and whether the hierarchy is clear.

[0083] Element information integrity: This includes whether elements such as IED name, communication parameters, and logical node information are complete.

[0084] Data consistency: This includes whether the data between different IEDs is consistent, and whether the data within the same IED is consistent.

[0085] Version management standardization: This includes whether the version numbers of files are standardized and whether the version change records are complete.

[0086] Correctness of virtual loop connections: This includes whether the virtual loop connections of each IED node are correct and whether they affect the correct operation of the protection device.

[0087] In this embodiment of the invention, it is necessary to determine the weight results of each potential influencing factor. Specifically, for each potential influencing factor, corresponding evaluation indicators and evaluation methods are formulated. Of course, the evaluation methods need to be associated with the above attributes, for example:

[0088] File structure rationality:

[0089] Evaluation indicators: the degree to which the document structure conforms to standards and specifications, and the clarity of its hierarchical structure.

[0090] Evaluation methods and strategies: By comparing the target file's structure with the standard specifications, check whether the structure meets the requirements and score it according to the degree of compliance; by analyzing the file's hierarchical structure, determine whether it is clear and give an appropriate score.

[0091] Element information integrity:

[0092] Evaluation metrics: the proportion of missing elements to the total number of elements, and the completeness of important elements.

[0093] Evaluation strategy: Count the number of missing elements in the target file, calculate the proportion of missing elements to the total number of elements, and score according to the proportion; check whether important elements (such as IED name, communication parameters, etc.) are complete. If they are complete, a higher score is given; otherwise, a lower score is given.

[0094] Data consistency:

[0095] Evaluation metrics: consistency of data between different IEDs, and consistency of data within the same IED.

[0096] Evaluation methods and strategies: By comparing the same data items between different IEDs, we can determine whether they are consistent and score them according to the degree of consistency; we can also check whether there are contradictions or inconsistencies in the data within the same IED and give corresponding scores.

[0097] Version management standards:

[0098] Evaluation metrics: standardization of version numbers and completeness of version change records.

[0099] Evaluation Methodology and Strategy: Check whether the version number of the target file meets the specification requirements. If it does, a higher score will be given; otherwise, a lower score will be given. Check whether the version change record is complete, including the reason for the change, the time of the change, and the content of the change. Scoring will be based on the completeness of the record.

[0100] Correctness of virtual loop connections:

[0101] Evaluation indicators: the standardization of virtual loop connections, and whether there are any issues affecting protection operation.

[0102] Evaluation Methodology and Strategy: The virtual loop connections of the target file are checked using the SCD loop check module. If no loop connection issues are found, a higher score is given; otherwise, a lower score is given. Issues are categorized as critical, general, or regulatory issues.

[0103] The above embodiments can evaluate the SCD file of the target smart substation based on the established evaluation indicators and evaluation methods, obtain the score of each potential influencing factor, and then use multi-factor comprehensive evaluation methods such as the analytic hierarchy process (AHP) to determine the weight of each potential influencing factor. Preferably, the steps are as follows:

[0104] Step 1: Establish a hierarchical structure model

[0105] 1. Target layer: "SCD normalization score", which is the final overall measure of the normalization level of SCD.

[0106] 2. Criterion Layer:

[0107] Document structure rationality: This includes whether the document conforms to the structural requirements of the standard specifications and whether the hierarchy is clear.

[0108] Element information integrity: This includes whether elements such as IED name, communication parameters, and logical node information are complete.

[0109] Data consistency: This includes whether the data between different IEDs is consistent, and whether the data within the same IED is consistent.

[0110] Version management standardization: This includes whether the version numbers of files are standardized and whether the version change records are complete.

[0111] Correctness of virtual loop connections: This includes whether the virtual loop connections of each IED node are correct and whether they affect the correct operation of the protection device.

[0112] 3. Solution Layer:

[0113] Evaluate an SCD document instance by comparing it with the various criteria at the criteria level to obtain its score in terms of standardization.

[0114] Step 2: Construct the judgment matrix

[0115] For each factor in the criterion layer, their relative importance to the target layer (SCD normalization) is compared pairwise to construct a judgment matrix. A 1-9 scale is typically used to determine the relative importance of the elements, as shown in the table below:

[0116]

[0117]

[0118] Assuming the criterion layer has 5 factors, the judgment matrix is ​​constructed as follows:

[0119]

[0120] Step 3: Calculate the weight vector

[0121] 1. First, calculate the product of the elements in each row of the judgment matrix, denoted as... For example, for the first row of the matrix above:

[0122]

[0123] Similarly, M2, M3, M4, and M5 can be calculated.

[0124] 2. Next, calculate. of The right root ( Let be the order of the matrix, here ), denoted as like:

[0125]

[0126] The others can be calculated similarly.

[0127] right After normalization, the weight vector w is obtained. That is:

[0128]

[0129] For example, calculate all Then, add them together to get the sum, and then use each one separately. Dividing by this sum yields the weight vectors of each criterion relative to the target layer.

[0130] Step 4: Consistency Check

[0131] 1. Calculate the largest eigenvalue of the judgment matrix. It can be done through the formula:

[0132]

[0133] Where Aw is the matrix A (judgment matrix) and the weight vector The first vector obtained by multiplication Each element.

[0134] 2. Calculate the consistency index (CI):

[0135]

[0136] 3. Find the average random consistency index RI for the corresponding order (here it is order 5) (it can be obtained through an existing reference table, generally RI = 1.12 for order 5).

[0137] 4. Calculate the consistency ratio (CR):

[0138]

[0139] If CR < 0.1, the judgment matrix is ​​considered to have satisfactory consistency and the weight vector is acceptable; otherwise, the judgment matrix needs to be readjusted until the consistency requirement is met.

[0140] Step 5: Determine the score of each scheme (i.e., the SCD file) under each criterion (standard evaluation template).

[0141] For each criterion, the SCD document to be evaluated is scored according to the pre-defined evaluation criteria or through actual surveys, assessments, etc. Below are examples of possible scoring criteria for each criterion (which can be adjusted according to specific circumstances):

[0142] File structure rationality:

[0143]

[0144] Element information integrity:

[0145]

[0146]

[0147] Data consistency:

[0148]

[0149] Version management standards:

[0150]

[0151]

[0152] Correctness of virtual loop connections:

[0153]

[0154] Suppose that after a detailed evaluation of a specific SCD file, the following scores are obtained under each criterion (example):

[0155] The score was 4 points under the "Reasonableness of Document Structure" criterion; and 3 points under the "Completeness of Element Information" criterion.

[0156] It scored 4 points under the "Data Consistency" criterion;

[0157] It scores 3 points under the "Version Management Standardization" criterion;

[0158] It scores 4 points under the criterion of "correctness of virtual loop connection".

[0159] Step 6: Calculate the execution score

[0160] The execution score of the SCD file is obtained by multiplying the weight vector W = [w1+w2+w3+w4+w5] (the weights of each criterion are calculated in the previous steps) with the score vector S = [s1+s2+s3+s4+s5] (the scores obtained by evaluating each criterion) of the SCD file under each criterion.

[0161] Right now:

[0162] Score = W·S = [w1·s] 1+ w2·s 2+ w3·s 3+ w4·s 4+ w5·s5]

[0163] It should be noted that the aforementioned execution score is used to control the substation. Since the SCD file is closely related to the control of the smart substation, a low score means that the current SCD file is insufficient for effective control of the smart substation. Furthermore, the SCD file defines the data model of the entire substation, covering the data objects and attributes of all intelligent electronic devices (IEDs). Calculating the SCD file's execution score, when the score meets preset conditions (e.g., exceeding a preset threshold), means that the current SCD file can be used to manage various data within the substation in a standardized manner, facilitating data exchange and processing between different devices, and contributing to real-time monitoring and control of substation equipment.

[0164] Step 7: Implement control strategies

[0165] When executing substation control strategies that match the SCD file, the control strategies include, but are not limited to, control strategies during the design and construction phases, such as using SCD file configuration tools to determine the functions and communication parameters of each intelligent electronic device (IED) and to establish virtual terminal connections between devices; control strategies during the maintenance and repair phases, such as reconfiguring relevant parameters according to the SCD file to ensure that new equipment can be integrated into the existing system and maintain the normal control functions of the substation; and other operating or control strategies, which are not specifically limited in this embodiment of the invention.
