Description

Technical Field

[0001] This invention relates to the field of intelligent substation technology, and in particular to a method, apparatus, equipment and medium for determining substation renovation and expansion information. Background Technology

[0002] Smart substations have a high degree of integration and complex virtual terminal connections between equipment. During renovation and expansion, modifications to the configuration of some of the upgraded equipment require re-downloading the configuration and debugging and verification of the circuits related to the upgraded equipment to ensure that the newly added and changed circuits function correctly after the configuration is re-downloaded. This is particularly true for bus differential protection. Since the addition of new bays changes the bus differential protection configuration, there is no direct method to verify whether the circuit between the bus differential protection and the original operating equipment has changed after the configuration update. Therefore, the common practice is to de-energize the original operating equipment and re-run the virtual circuit between it and the bus differential protection to confirm that the circuit between the bus differential protection and the original operating equipment is normal after the renovation and expansion work.

[0003] To address the aforementioned issues, some existing technologies determine the range of configuration changes caused by substation expansion and renovation by statically comparing the Substation Configuration Description (SCD) files before and after the expansion and renovation. One feasible method is to extract communication parameters and virtual terminal connection configuration information, calculate the sub-cyclic redundancy check (CRC) between each IED in the SCD file, compare the changes in the sub-CRC between each IED in the SCD file before and after the expansion and renovation, and determine the range of circuit changes caused by the expansion and renovation.

[0004] The theoretical basis for the above method is that the configuration description principles of the SCD file before and after the renovation and expansion are consistent, ensuring that the methods for extracting communication parameters and virtual terminal connection configurations are consistent. However, for early smart substations, some stations do not have SCD files, or even if SCD files exist, equipment manufacturers create independent private configuration files based on the SCD files. These private configuration files may correspond to configuration files in various formats, leading to inconsistencies in the configuration description principles of the SCD file before and after the renovation and expansion. In this case, it is impossible to achieve configuration change verification by calculating CRC at the SCD level. Summary of the Invention

[0005] This invention provides a method, apparatus, equipment, and medium for determining substation renovation and expansion information, so as to realize automatic verification of the scope of substation renovation and expansion.

[0028] Example 1

[0029] Figure 1 This invention provides a flowchart of a method for determining substation renovation and expansion information according to Embodiment 1. This embodiment is applicable to determining the scope of renovation and expansion of smart substations. The method can be executed by a substation renovation and expansion information determining device, which can be implemented in hardware and / or software and can be configured in an electronic device. Figure 1 As shown, the method includes:

[0030] S110. Obtain the historical configuration file set of the historical intelligent devices included before the substation renovation, and the current configuration file set of the current intelligent devices included after the substation renovation.

[0031] In this embodiment, a substation can be understood as an intelligent substation including intelligent devices. Historical intelligent devices can be understood as the intelligent devices included in the substation before the renovation, such as intelligent terminals and intelligent secondary devices. The historical configuration file set can be understood as a set of historical configuration files composed of the process-level configuration files of all historical intelligent devices. These configuration files may be CCD files in a general format, or they may be private configuration files in various forms such as .xml, .cfg, and .txt. Current intelligent devices can be understood as the intelligent devices included in the substation after the renovation, such as intelligent terminals and intelligent secondary devices. The current configuration file set can be understood as a set of current configuration files composed of the process-level configuration files of all current intelligent devices.

[0032] Specifically, before substation renovation, the processor can search for the corresponding SCD files of each historical intelligent device in the relevant storage media, forming a historical configuration file set from all the SCD files of historical intelligent devices. Regardless of whether the historical intelligent device has an SCD file, the processor can retrieve configuration files from the device before downloading new configuration files to the device during renovation or expansion, thus forming a historical configuration file set. The processor can also download the configuration files from a pre-defined configuration file operation and control system before renovation or expansion, forming a historical configuration file set from these configuration files.

[0033] For example, taking a substation as an example, this substation has no SCD file. Each equipment manufacturer independently configures its process layer configuration file. Manufacturer A's equipment PL2201A configuration file is PL2201A.xml, Manufacturer B's equipment PM2201A configuration file is PM2201A.cfg, and Manufacturer C's equipment IL2201A configuration file is IL2201A.txt. The historical configuration file set M can be M = {A1, B1, C1, D1, ...}, where A1, B1, C1, D1, ... represent the process layer configuration file corresponding to each historical intelligent device. The current configuration file set N can be N = {A2, B2, C2, D2, ...}, where A2, B2, C2, D2, ... represent the process layer configuration file corresponding to each current intelligent device. Here, A1 corresponds to A2, B1 corresponds to B2, C1 corresponds to C2, D1 corresponds to D2, and so on. That is, the order of the configuration files in the configuration file set corresponds to the same intelligent device before and after the renovation and expansion.

[0034] S120. Based on the preset general configuration template file, determine the first configuration file set corresponding to the historical configuration file set and the second configuration file set corresponding to the current configuration file set.

[0035] It is important to know that a general configuration template file can be understood as a general format file used to convert configuration file sets of different formats into the same format. This general configuration template file describes the core configuration information related to the process layer configuration, which may include control block communication parameters, GOOSE and SV publish control block configuration parameters, GOOSE and SV subscribe control block configuration parameters, and corresponding virtual terminal connection configurations.

[0036] For example, control block communication parameters include: IED name parameter; GSE cbName parameter, ldInst parameter; Address parameters belonging to GSE cb, including MAC-Address, VLAN-ID, VLAN-PRIORITY, APPID, MinTime parameter, MaxTime parameter; SMV cbName parameter, ldInst parameter; Address parameters belonging to SMV cb, including MAC-Address, VLAN-ID, VLAN-PRIORITY, APPID parameter. GOOSE published control block configuration parameters include: GOCBrefname parameter under GOOSEPUB; GSEControl parameters, including appID, confRev, datSet, name, type; ConnectedAP parameters, including apName, iedName; PhysConn parameters, including type, P type; DataSet name parameter; FCDA parameters belonging to DataSet, including bType, daName, doName, fc, ldInst, lnClass, DAIname, sAddr. The SV release control block configuration parameters include: the SMVCBrefname parameter under SVPUB; SampledValueControl parameters, including confRev, datSet, multicast, name, nofASDU, smpRate, and smvID; ConnectedAP parameters, including apName and iedName; PhysConn parameters, including type and P type; DataSetname parameter; and the FCDA parameters belonging to the DataSet, including bType, daName, doName, fc, ldInst, lnClass, DOI name, SDI name, DAI name, and sAddr.The GOOSE subscription control block configuration parameters and corresponding virtual terminal connection configurations include: GOCBrefname under GOOSESUB; GSEControl parameters, including appID, confRev, datSet, name, and type; ConnectedAP parameters, including apName and iedName; GSE cbName and ldInst parameters; Address parameters belonging to GSE cb, including MAC-Address, VLAN-ID, VLAN-PRIORITY, APPID, MinTime, and MaxTime parameters; DataSet name parameter; and FCDA parameters belonging to DataSet, including bType, daName, doName, fc, ldInst, lnClass, lnInst, prefix, intAddr name, DAI name, and sAddr. The FCDA parameter intAddr name of the DataSet describes the virtual terminal connection configuration. The SV subscription control block configuration parameters and corresponding virtual terminal connection configurations include: SMVCBrefname under SVSUB; SampledValueControl parameters, including confRev, datSet, multicast, name, nofASDU, smpRate, and smvID; ConnectedAP parameters, including apName and iedName; SMV cbName and ldInst parameters; Address parameters belonging to the SMV cb, including MAC-Address, VLAN-ID, VLAN-PRIORITY, and APPID; DataSet name parameter; and FCDA parameters belonging to the DataSet, including bType, daName, doName, fc, ldInst, lnClass, DOI name, SDI name, DAI name, and sAddr. The FCDA parameter intAddrname of the DataSet described above describes the virtual terminal connection configuration.

[0037] In this embodiment, the first configuration file set can be understood as the historical configuration file set generated according to a general configuration template. The second configuration file set can be understood as the current configuration file set generated according to a general configuration template.

[0038] Specifically, since the configuration file sets corresponding to different secondary devices may have different formats, the processor can convert different configuration file sets into configuration file sets under a unified universal format based on a universal configuration template file that defines a common format. The processor can extract the corresponding configuration description portions of the required parameters from the preset universal configuration template file in the historical configuration file set according to set rules. For file formats from different manufacturers, conversion can be performed according to a pre-defined mapping relationship to form a first configuration file set corresponding to the historical configuration file set. The processor can also extract the corresponding configuration description portions of the required parameters from the preset universal configuration template file in the current configuration file set according to set rules. For file formats from different manufacturers, conversion can be performed according to a pre-defined mapping relationship to form a second configuration file set corresponding to the current configuration file set. Parameters that exist in the current and historical configuration file sets but not in the universal configuration file set are not reflected in the formed first and second configuration file sets. Parameters that exist in the universal configuration file set but not in the historical and current configuration file sets are retained as default values ​​in the formed first and second configuration file sets.

[0039] For example, the historical configuration file set M′ can be M′={A′1,B′1,C′1,D′1,……}, and the current configuration file set N′ can be N′={A′2,B′2,C′2,D′2,……}.

[0040] S130. Determine the substation renovation and expansion information based on the first configuration file set and the second configuration file set.

[0041] In this embodiment, the renovation and expansion information can be understood as information used to indicate the scope of renovation and expansion of the substation.

[0042] Specifically, since the renovation and expansion of a substation can be determined by checking whether the virtual circuits between interconnected devices have changed, and the status of virtual circuits can be reflected by CRC values, in order to determine whether the devices with interconnected relationships and their corresponding virtual circuits in the substation have changed, the processor can generate a historical list of intelligent devices with virtual terminal connections before and after the renovation and expansion, and a current list of intelligent devices, based on a first configuration set and a second configuration set. CRC values ​​are calculated using the configuration information of the intelligent devices and their corresponding sub-devices in the first configuration set and the historical intelligent device list to form a CRC list for the historical intelligent devices. Similarly, CRC values ​​are calculated using the configuration information of the intelligent devices and their corresponding sub-devices in the second configuration set and the current intelligent device list to form a CRC list for the current intelligent devices. The corresponding items in the two CRC lists are then compared to identify groups with different values. Groups with different values ​​indicate that the circuits between the corresponding intelligent devices have changed after the renovation and expansion, while groups with no difference indicate that the circuits between the corresponding intelligent devices have not changed. Information on whether the corresponding connection relationships have changed is then output, and this information is used as the renovation and expansion information.

[0043] The technical solution of this invention involves obtaining the historical configuration file set of the intelligent devices included before the substation renovation, and the current configuration file set of the current intelligent devices included after the renovation; determining a first configuration file set corresponding to the historical configuration file set and a second configuration file set corresponding to the current configuration file set based on a preset general configuration template file; and determining the substation renovation and expansion information based on the first and second configuration file sets. This method obtains the configuration file sets before and after the substation renovation and expansion, extracts the corresponding configuration parameters according to the preset general configuration template file to form the first and second configuration file sets, calculates the CRC before and after the renovation and expansion, and determines the substation renovation and expansion information based on the difference between the CRC values. This achieves automatic determination of the scope of configuration changes during renovation and expansion. This method can be used in different forms of device configuration files, improving its versatility.

[0044] Example 2

[0045] Figure 2 This is a flowchart illustrating a method for determining substation renovation and expansion information according to Embodiment 2 of the present invention. This embodiment is a further refinement based on the above embodiments. Figure 2 As shown, the method includes:

[0046] S210. Obtain the historical configuration file set of the historical intelligent devices included before the substation renovation, and the current configuration file set of the current intelligent devices included after the substation renovation.

[0047] S220. Obtain the preset configuration description mapping relationship.

[0048] It is important to know that for specific parameters existing in various private configuration files, which cannot be directly extracted and filled into the first configuration file set and the second configuration file set due to differences in description methods, a mapping relationship between the configuration description of each device manufacturer's private configuration file and the configuration description of the general configuration template file can be established based on the specific situation and the device manufacturer. This configuration description mapping relationship describes the method for extracting and filling information between the configuration description part of each device manufacturer's private configuration file and the configuration description part of the general configuration template file.

[0049] Specifically, the processor can obtain a preset configuration description mapping relationship from the storage medium.

[0050] S230. Based on the configuration description mapping relationship, determine the historical configuration parameters in the historical configuration file set and the current configuration parameters in the current configuration file set.

[0051] Specifically, the processor can determine the historical configuration parameters filled into the general configuration template file from the historical configuration file set based on the configuration description mapping relationship, and determine the current configuration parameters filled into the general configuration template file from the current configuration file set.

[0052] S240. Determine the first configuration file set based on historical configuration parameters and general configuration template files.

[0053] Specifically, the processor can fill historical configuration parameters into the corresponding items in the general configuration template file to generate the first configuration file set.

[0054] S250. Determine the second configuration file set based on the current configuration parameters and the general configuration template file.

[0055] Specifically, the processor can fill the current configuration parameters into the corresponding items in the general configuration template file to generate a second configuration file set.

[0056] For example, when device manufacturer A's private configuration file describes the control block communication parameter GSE cbName, the configuration description is GOOSE controlblockName. When device manufacturer B's private configuration file describes the control block communication parameter GSE cbName, the configuration description is GSE controlblockName. According to the configuration description mapping relationship, the value of the control block communication parameter GOOSE controlblockName in device manufacturer A's private configuration file is extracted and filled into the value of GSE cbName in the general configuration template file. Similarly, the value of the control block communication parameter GSE controlblockName in device manufacturer B's private configuration file is extracted and filled into the value of GSE cbName in the general configuration template file. This means that even when different device manufacturers' private configuration files have different descriptions of the same configuration description part in the general configuration template file, a first configuration file set and a second configuration file set can still be generated.

[0057] S260. Based on the historical configuration file set and the current configuration file set, determine the historical sub-device list corresponding to each historical smart device and the current sub-device list corresponding to each current smart device.

[0058] In this embodiment, the historical sub-device list can be understood as a list of sub-devices connected to the virtual terminals of the historical smart devices before the upgrade and expansion. The current sub-device list can be understood as a list of sub-devices connected to the virtual terminals of the current smart devices after the upgrade and expansion.

[0059] Specifically, the processor can determine the list of historical sub-devices corresponding to each historical smart device and the list of current sub-devices corresponding to each current smart device based on the virtual terminal connection relationships in the historical configuration file set and the current configuration file set.

[0060] Based on the above embodiments, the steps of determining the historical sub-device list corresponding to each historical smart device and the current sub-device list corresponding to each current smart device according to the historical configuration file set and the current configuration file set can be further optimized as follows:

[0061] a1. Extract the historical virtual terminal connection relationships from the historical configuration file set, and the current virtual terminal connection relationships from the current configuration file set.

[0062] In this embodiment, the historical virtual terminal connection relationship can be understood as the connection relationship between sub-devices connected to each smart device via virtual terminals before the renovation and expansion. The current virtual terminal connection relationship can be understood as the connection relationship between sub-devices connected to each smart device via virtual terminals after the renovation and expansion.

[0063] Specifically, the processor can parse the historical configuration file set and the current configuration file set, extract the historical virtual terminal connection relationships in the historical configuration file set, and the current virtual terminal connection relationships in the current configuration file set.

[0064] b1. Based on the historical virtual terminal connection relationship, determine the historical sub-devices connected to each historical smart device, and form a list of historical sub-devices corresponding to each historical smart device.

[0065] In this embodiment, the historical sub-device can be understood as a sub-device connected to the historical smart device via a virtual terminal.

[0066] Specifically, the processor can determine the historical sub-devices connected to each historical smart device based on the historical virtual terminal connection relationship, and form a list of historical sub-devices corresponding to each historical smart device.

[0067] For example, the list of historical sub-devices corresponding to each historical smart device can be represented as: A1: X1, Y1, Z1... and so on. Before the renovation and expansion, the historical smart device centered on A1 includes historical sub-devices with virtual terminal connections to it, such as X1, Y1, Z1... and then the corresponding list of historical sub-devices is formed with B1, C1, D1... as the centers in sequence.

[0068] c1. Based on the current virtual terminal connection relationship, determine the current sub-devices connected to each current smart device, and form a list of current sub-devices corresponding to each current smart device.

[0069] Specifically, the processor can determine the current sub-devices connected to each current smart device based on the current virtual terminal connection relationship, and form a list of current sub-devices corresponding to each current smart device.

[0070] For example, the current sub-device list corresponding to each current smart device can be represented as: A2: X2, Y2, Z2... and so on. After the renovation and expansion, the current smart device centered on A2, and the current sub-devices with virtual terminal connections to it include X2, Y2, Z2... Then, the corresponding current sub-device lists are formed with B2, C2, D2... as the centers in sequence.

[0071] S270. Based on the first configuration file set and the list of historical sub-devices, determine the list of historical verification codes between each historical smart device and its corresponding historical sub-device.

[0072] In this embodiment, the historical verification code list can be understood as a list composed of CRC values ​​between historical smart devices and historical sub-devices.

[0073] Specifically, the processor can calculate the historical verification code value between each historical smart device and its corresponding historical sub-device using a set CRC algorithm based on the first configuration file set and the list of each historical sub-device, thereby forming a historical verification code list based on the historical verification code value.

[0074] Furthermore, based on the above embodiments, the step of determining the historical verification code list between each historical smart device and its corresponding historical sub-device according to the first configuration file set and the list of each historical sub-device can be optimized as follows:

[0075] a2. Extract the historical control block communication parameters, historical publish control block configuration parameters, and historical subscribe control block configuration parameters from the first configuration file as historical configuration information.

[0076] In this embodiment, the historical control block communication parameters can be understood as configuration parameters used to indicate the sending and receiving of data by the historical smart device before the upgrade or expansion. The historical publish control block configuration parameters can be understood as configuration parameters used to indicate the GOOSE and SV publish control block configuration parameters. The historical subscribe control block configuration parameters can be understood as the GOOSE and SV subscribe control block configuration parameters between the historical smart device and the historical sub-device.

[0077] Specifically, the processor can extract the historical control block communication parameters, historical publish control block configuration parameters, historical subscribe control block configuration parameters between two historical smart devices, and the corresponding virtual terminal connection configuration from the first configuration file as historical configuration information.

[0078] b2. For historical smart devices, determine the historical verification code between the historical smart device and its corresponding historical sub-devices based on the historical configuration information.

[0079] In this embodiment, the historical verification code can be understood as the verification code between the historical smart device before the renovation and expansion and the corresponding historical sub-devices.

[0080] Specifically, the processor can calculate the historical verification code between the historical smart device and its corresponding historical sub-devices according to the historical configuration information and the set CRC algorithm for the historical smart device.

[0081] c2. Determine the list of historical verification codes based on each historical verification code.

[0082] Specifically, the processor can generate a list of historical verification codes based on each historical verification code.

[0083] For example, following the description in the above example, the historical check code list can be: CRC(A1-X1), CRC(A1-Y1), CRC(A1-Z1)... and so on.

[0084] S280. Based on the second configuration file set and the list of current sub-devices, determine the current verification code list between each current smart device and its corresponding current sub-device.

[0085] In this embodiment, the current check code list can be understood as a list composed of the CRC values ​​between the current smart device and the current sub-device.

[0086] Specifically, the processor can calculate the current verification code value between the current smart device and the corresponding current sub-device using the set CRC algorithm based on the second configuration file set and the list of each current sub-device, and then form a current verification code list based on the current verification code value.

[0087] Furthermore, based on the above embodiments, the step of determining the current verification code list between each current smart device and its corresponding current sub-device according to the second configuration file set and the list of each current sub-device can be optimized as follows:

[0088] a3. Extract the current control block communication parameters, current publish control block configuration parameters, and current subscribe control block configuration parameters from the second configuration file as the current configuration information.

[0089] Specifically, the processor can extract the current control block communication parameters, the current publishing control block configuration parameters, the current subscription control block configuration parameters between the two current smart devices, and the corresponding virtual terminal connection configuration from the second configuration file as the current configuration information.

[0090] b3. For the current smart device, determine the current verification code between the current smart device and each corresponding current sub-device based on the current configuration information.

[0091] In this embodiment, the current verification code can be understood as the verification code between the current smart device after the upgrade and expansion and the corresponding current sub-devices.

[0092] Specifically, the processor can calculate the current verification code between the current smart device and its corresponding sub-devices according to the current configuration information and the set CRC algorithm for the current smart device.

[0093] c3. Determine the current verification code list based on each current verification code.

[0094] Specifically, the processor can generate a list of current verification codes based on each current verification code.

[0095] For example, following the description in the above example, the current check code list can be: CRC(A2-X2), CRC(A2-Y2), CRC(A2-Z2)... and so on.

[0096] S290. Determine the substation renovation and expansion information based on the historical verification code list and the current verification code list.

[0097] Specifically, the processor can compare the historical verification code list with the current verification code list and determine the substation's renovation and expansion information based on the comparison results.

[0098] Based on the above embodiments, the step of determining the substation renovation and expansion information according to the historical verification code list and the current verification code list can be optimized as follows:

[0099] a4. For historical verification codes in the historical verification code list, compare the historical verification codes with the corresponding current verification codes in the current verification code list to determine whether the target smart device and target sub-device corresponding to the current verification code are in the difference group.

[0100] In this embodiment, the difference group can be understood as the group in which the loop between the smart device and the smart sub-device changes after the renovation and expansion.

[0101] Specifically, for historical verification codes in the historical verification code list, the processor can compare the historical verification codes with the corresponding current verification codes in the current verification code list. Based on whether the two are the same, it can determine whether the target smart device and target sub-device corresponding to the current verification code belong to the difference group. Groups without differences are designated as indifferent groups, and groups with differences are designated as difference groups.

[0102] For example, the processor can compare CRC(A1-X1) with CRC(A2-X2), compare CRC(A1-Y1) with CRC(A2-Y2), and so on. Based on the comparison results, the group with differences is determined to be A2-X2, and the group without differences is determined to be A2-Y2. That is, the loop between A2-X2 has changed, while the loop between A2-Y2 has not changed.

[0103] b4. Based on each difference group, determine the list of difference groups.

[0104] Specifically, the processor can generate a list of difference groups based on each difference group.

[0105] c4. Based on the list of difference groups, determine the substation renovation and expansion information.

[0106] Specifically, the processor can determine whether the connection relationships between corresponding smart devices have changed based on the difference group list, and use this information as renovation and expansion information. This determines the renovation and expansion information for the substation.

[0107] This second embodiment uses the following setup: It obtains the configuration file sets before and after the renovation, extracts the configuration information from these sets according to the configuration description mapping relationship, and fills it into a preset general configuration template file, forming a first configuration file set and a second configuration file set. These sets are then used to create a current sub-device list and a historical sub-device list. This allows for the determination of the current and historical verification code lists corresponding to the current and historical sub-device lists.
