Description

Technical Field

[0001] The present invention relates to the field of intelligent substations, and more specifically, to a method and system for verifying the consistency of non-homologous configurations based on effective configuration information. Background Art

[0002] At present, there are SCD file integrated configuration and independent configuration of each IED in the smart substation. There are also different versions of SCD files and IED independent configuration files in different construction periods. Each configuration file can be officially put into operation and take effect only after configuration, inspection, verification, debugging and acceptance. In the above work process and subsequent substation reconstruction, expansion and maintenance work, the configuration file will be partially or completely updated or modified. In this process, there will be configuration errors such as modification, update and download due to inconsistent configuration. Finally, the unverified, wrong or inconsistent configuration will be downloaded to the equipment and put into operation, which may lead to more serious relay protection misoperation, refusal to operate or monitoring system erroneous signaling, causing unnecessary maintenance and operation work.

[0003] In view of the above problems, it is necessary to carry out consistency verification of configuration files, and there are some existing verification methods in the prior art. For example, Background Technology Document 1: System and method for consistency verification of substation monitoring database access model and SCD, which can parse SCD and monitoring database access model, respectively carry out consistency comparison of signal information and structural information, and realize consistency verification of monitoring database access model and SCD. Background Technology Document 2: A method for online detection of consistency between SCD file and IED model, which can realize consistency detection of SCD file and IED model by reading IED model information online and comparing it with SCD file. Background Technology Document 3: ICD and SCD consistency verification method based on model object semantics, which converts the Schema model of ICD and SCD files into RDFSchema model, and uses RDF data object association relationship to find the matching object part of ICD file and SCD file, and performs consistency verification to realize consistency verification of ICD file and SCD file.

[0004] However, the above research results are all oriented towards the consistency verification of substation configuration files, and the technical methods described have their own limitations. For example, Background Technology Document 1 only solves the consistency verification of the substation monitoring database access model and SCD, Background Technology Document 2 only solves the consistency verification of the SCD file and the IED model, and Background Technology Document 3 also only solves the consistency verification of the ICD and SCD models. The technical routes and principles adopted by each verification method are very different, and they are not interoperable with each other. They do not consider that the same configuration file needs to use different configuration description parts for different application scenarios, and do not consider distinguishing between the core valid configuration description and the invalid configuration description in the configuration file. If the consistency verification result contains invalid information that is irrelevant to the target application, the verification result is not reasonable.

[0005] In view of the above problems, a new consistency verification method for non-homologous configurations in substations is urgently needed. Summary of the invention

[0027] Figure 2 The present invention is a schematic diagram of the cutting principle of an integrated configuration file in a non-homologous configuration consistency verification method based on valid configuration information. DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present invention clearer, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The embodiments described in the present invention are only embodiments of a part of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments not recorded in the present invention obtained by ordinary technicians in this field according to the embodiments recorded in the present invention without making creative work should belong to the protection scope of the present invention.

[0029] Figure 1 FIG. 1 is a schematic diagram of the steps of a method for checking consistency of non-homologous configurations based on valid configuration information of the present invention. Figure 1 As shown, the first aspect of the present invention relates to a method for verifying consistency of non-homologous configurations based on valid configuration information, and the method includes steps 1 to 3.

[0030] Step 1: Obtain verification requirements for non-homogeneous configurations, and collect configuration files from non-homogeneous devices based on the verification requirements.

[0031] It can be understood that the present invention analyzes the characteristics of the configuration description information of the configuration file under different application requirements, splits the configuration description information in the configuration file into valid configuration information and invalid configuration information, performs cyclic redundancy calculation based on the valid configuration information, generates a configuration file check code, extracts the characteristic information of the configuration file, and groups non-homologous configuration files with consistent characteristic information as a group, and compares whether their file check codes are consistent. This consistency represents the configuration description consistency of non-homologous configuration files under specific application requirements.

[0032] Therefore, the present invention sets a rule for dividing the configuration information in the configuration files such as SCD, RCD, ICD, CID, CCD, CSD and other integrated configuration files and separate configuration files of smart substations according to different application requirements, and divides the configuration information in the configuration files into valid configuration information and invalid configuration information under various application requirement conditions.

[0033] Preferably, the non-homologous devices include substation interval layer devices, substation process layer devices, substation station control layer devices, substation communication gateway machines, and substation switches. Non-homologous configurations include process layer configurations, interval layer configurations, station control layer configurations, and switch configurations; configuration files include SCD configuration files, CID configuration files, CCD configuration files, CSD configuration files, ICD configuration files, and RCD configuration files. It is understandable that the present invention can implement verification between different sources and different configuration contents based on various demand information generated during the actual operation of the substation. In order to provide a general method, the present invention involves verification requirements.

[0034] Preferably, the verification requirement includes relevant information of the non-homologous devices, non-homologous configurations and configuration files to be verified.

[0035] Specifically, in the embodiments of the present invention, various application requirement conditions include but are not limited to: Condition 1, description consistency comparison of the process layer configuration of the substation interval layer equipment and process equipment configuration files. Condition 2, description consistency comparison of the station control layer configuration of the substation monitoring background and interval layer equipment configuration files. Condition 3, description consistency comparison of the station control layer configuration of the substation communication gateway and interval layer equipment configuration files. Condition 4, description consistency comparison of the process layer configuration of the substation SCD configuration file and CID configuration file. Condition 5, description consistency comparison of the station control layer configuration of the substation SCD configuration file and CID configuration file. Condition 6, description consistency comparison of the process layer configuration of the substation SCD configuration file and CCD configuration file. Condition 7, description consistency comparison of the switch configuration of the substation SCD configuration file and CSD configuration file. Condition 8, description consistency comparison of the process layer configuration of each IED device by different versions of SCD configuration files of the substation. Condition 9, description consistency comparison of the station control layer configuration of each IED device by different versions of SCD configuration files of the substation. Condition 10: Compare the description consistency of the process layer and station control layer configuration of each IED device in different versions of SCD configuration files of the substation. Condition 11: Compare the description consistency of the configuration of each IED device in different versions of SCD configuration files of the substation.

[0036] In view of the above-mentioned different verification requirements, the present invention can extract respective valid configuration information from non-homologous configuration files according to the configuration information division method.

[0037] Step 2: extract valid configuration information from the configuration file respectively, and use a cyclic redundancy algorithm to calculate the check code of the valid configuration information.

[0038] It should be noted that after obtaining different configuration files, the present invention will obtain different configuration information according to the verification requirements, and adopt a similar method to extract valid configuration information and filter out invalid configuration information.

[0039] Preferably, the effective configuration information is selected based on the application scenario of the configuration file; and the application scenario includes message communication, background monitoring, data forwarding and data exchange.

[0040] It is understandable that the valid configuration information and invalid configuration information in the present invention can be selected according to different actual conditions. Specifically, when the configuration file is used for process layer GOOSE and SV communication behaviors, the valid configuration information includes the control block definition, control block communication parameters, control block data channel definition, control block data channel type, control block data channel path, virtual terminal subscription relationship, etc. in the model file.

[0041] When the configuration file is used to monitor the background database configuration, the effective configuration information includes the data set definition, data set data channel definition, data set data channel type, data set data channel path, data set data channel description, etc. in the model file.

[0042] When the configuration file is used for data forwarding configuration of a communication gateway, the valid information includes the data set definition, data set data channel definition, data set data channel type, data set data channel path, data set data channel description, etc. in the model file.

[0043] When the configuration file is used to configure the switch CSD to take effect, the valid information includes the control block definition in the model file, the control block communication parameters, and the physical port connection configuration of the device.

[0044] Preferably, the configuration file also includes a separate configuration file and an integrated configuration file; and the effective configuration information of the integrated configuration file is generated based on a target separate configuration file among the multiple separate configuration files after cutting out multiple separate configuration files from the integrated configuration file based on the application scenario of the configuration file; wherein the target separate configuration file is selected from the multiple separate configuration files according to the application scenario of the configuration file.

[0045] It is understandable that, depending on actual verification requirements, there may be a verification between a separate configuration file and an integrated configuration file, or there may be a verification between two integrated configuration files.

[0046] The separate configuration file here means that the configuration target of the configuration file is only for a single device, while the integrated configuration file can be for multiple devices regardless of how the configuration content is obtained or the devices it is configured for. Therefore, it can be seen that the integrated configuration file can also be understood as a collection of multiple separate configuration files from a certain perspective.

[0047] Figure 2 Schematic diagram of the cutting principle of integrated configuration files in a non-homologous configuration consistency verification method based on effective configuration information of the present invention. Figure 2 As shown, for example, for a set of separate configuration files and integrated configuration files, when extracting the effective configuration information of the integrated configuration file, Figure 2 As shown, the integrated configuration file is first cut according to the information characteristics of the separate configuration file, and the configuration description information of the target separate configuration file in the integrated configuration file is generated. Then, the valid configuration information of the configuration description information of the target separate configuration file in the integrated configuration file is extracted, and the configuration file verification code of the target separate configuration file described in the integrated configuration file under the verification requirement is calculated. The configuration file verification codes of the separate configuration file and the integrated configuration file are compared to determine the consistency of the configuration description between the separate configuration file and the integrated configuration file.

[0048] Specifically, in the present invention, the characteristic information of the individual configuration files can be firstly extracted, and then the characteristic information of each independent configuration description part in the integrated configuration file can be extracted. By comparing the characteristic information of the individual configuration files with the characteristic information of the integrated configuration files, the partial configuration and its boundary described for the target individual configuration file in the integrated configuration file are determined. Subsequently, according to the partial configuration and its boundary described for the target individual configuration file by the determined integrated configuration file, the partial configuration in the integrated configuration file is cut to generate the partial configuration described for the target individual configuration file.

[0049] In the present invention, by extracting the valid configuration information of the separate configuration file and the cut partial configuration file under the verification requirement, the configuration file verification codes corresponding to the valid information of the separate configuration file and the cut partial configuration file can be calculated respectively. The above two configuration file verification codes are compared to determine the consistency of the separate configuration file and the cut partial configuration file. This consistency represents the configuration consistency of the separate configuration file and the integrated configuration file under a certain type of application requirement conditions. For ease of understanding and expression, it is described here and in the following as the configuration consistency under the first type of application requirement conditions.

[0050] In another embodiment of the present invention, if it is necessary to compare the consistency of two integrated configuration files for some individual configuration descriptions, the configuration description information of all individual configuration files in the integrated configuration file can be cut based on the configuration file cutting method, the configuration description information of all individual configuration files in the integrated configuration file is generated, and the configuration file verification codes under the verification requirements are calculated in sequence, and the feature information of the configuration description information of each individual configuration file is extracted at the same time, and the configuration file verification codes of the individual configuration files with the same feature information cut out from the two groups of integrated configuration files are compared to determine the consistency of the configuration descriptions of each individual configuration file within the two groups of integrated configuration files.

[0051] The more detailed steps of this step include: extracting the characteristic information of each independent configuration description part in the integrated configuration file respectively, and determining the partial configuration and its boundary described by each separate configuration file in the integrated configuration file by comparing the characteristic information of the separate configuration parts in the two sets of integrated configuration files. Then, the present invention cuts the partial configuration in the integrated configuration file according to the determined partial configuration and its boundary of the integrated configuration file, and generates the partial configuration described by each separate configuration file. Then, extract the effective configuration information of each cut partial configuration file, calculate the configuration file check code corresponding to the effective information of each cut partial configuration file respectively, compare the characteristic information of each cut partial configuration file, and combine the pairs with the same characteristic information.

[0052] The present invention compares the checksums of two configuration files in a pair combination to determine the consistency of each cut partial configuration file in the two sets of integrated configuration files, and the consistency represents the consistency of the configuration description of each individual device in the two sets of integrated configuration files under the first type of application requirement conditions.

[0053] Preferably, the cyclic redundancy algorithm is: remove content elements and symbol elements from the valid configuration information, sort the remaining attribute elements, and convert them into UTF-8 sequences; perform cyclic redundancy calculation on the UTF-8 sequence to obtain a CRC check code.

[0054] It is understandable that the present invention can use a cyclic redundancy calculation method to calculate a check code for the extracted valid configuration information to generate a configuration file check code under the first type of application requirement conditions. The check code serves as a unique identifier describing the configuration information of the configuration file under the first type of application requirement conditions.

[0055] The cyclic redundancy calculation method is as follows: remove spaces, line feeds, carriage returns, and list characters between content elements and attribute elements from all extracted valid configuration information, arrange the attributes of all extracted elements in the order of letters az, and end the elements without sub-elements and assigned values ​​with " / >". Convert the sequence used to calculate the check code into a UTF-8 sequence, calculate the four-byte CRC-32 check code, and if the calculated four-byte CRC-32 check code is less than four bytes, fill the high byte with 0x0.

[0056] Among them, the CRC parameters are as follows:

[0057] CRC bit width: 32;

[0058] Generate item Poly: 04C11DB7;

[0059] Initialization value Init: FFFFFFFF;

[0060] Whether the data to be tested is reversed RefIn: True;

[0061] Is the calculated value reversed RefOut: True;

[0062] Output data XOR item XorOut: FFFFFFFF;

[0063] The verification result of the string "123456789abcdef" is Check: A2B4FD62.

[0064] Step 3: Compare the check codes to obtain consistency check results.

[0065] Specifically, after completing the consistency comparison of non-homologous configuration files under all categories of different verification requirements, the present invention records the configuration file verification code of each configuration file under each category of application conditions as a basis for verification and comparison, and outputs the consistency comparison result of non-homologous configuration files under each category of application conditions.

[0066] A second aspect of the present invention relates to a non-homologous configuration consistency verification system based on valid configuration information, the system comprising an acquisition module, an extraction module and a verification module; wherein the acquisition module is used to obtain the verification requirements of the non-homologous configuration, and to collect configuration files from non-homologous devices according to the verification requirements; the extraction module is used to extract the valid configuration information from the configuration files respectively, and to calculate the verification code of the valid configuration information using a cyclic redundancy algorithm; the verification module is used to compare the verification code to obtain a consistency verification result.
