[0003] In the prior art, engineering designers can convert design documents into power grid information models and deliver them to reviewers for review. Reviewers need to parse the power grid information models before reviewing. If the review fails, engineering designers need to return to the design documents again for adjustment, and then convert the adjusted design documents into power grid information models and deliver them to reviewers for re-review. Due to the large volume of transmission and transformation projects, during the above process of repeatedly converting or parsing power grid information models, the lag situation is relatively serious, seriously affecting the editing efficiency.

[0032] Embodiment 1

[0033] Figure 1a It is a flowchart of a hierarchical storage method for a power grid information model provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of parsing the full-scale power grid information model to obtain node data, analyzing and processing the node data to generate an engineering database and an equipment database, and combining the hierarchical storage request sent by the user to realize the hierarchical storage of the full-scale power grid information model. This method can be executed by a hierarchical storage device for the power grid information model. The hierarchical storage device for the power grid information model can be implemented in the form of hardware and / or software, and the hierarchical storage device for the power grid information model is generally configured in a computer or server with data processing functions. As Figure 1a shown, the method includes:

[0034] S110. Parse the full-scale power grid information model uploaded by the user, obtain multiple power grid information files in the full-scale power grid information model, and generate multiple node data in the cache using the power grid information files.

[0035] The full-scale power grid information model is a power grid information model directly converted from the design documents of the entire power transmission and transformation project after the engineering designers complete the design of the entire power transmission and transformation project. The full-scale power grid information model may include various levels of information, equipment information, and attribute information matching the various levels of information and equipment information in the power transmission and transformation project.

[0036] Further, in the full-scale power grid information model, various types of information such as hierarchical information, device information, and attribute information are all stored in the form of files, that is, the power grid information files mentioned in the embodiments of the present invention.

[0037] Optionally, after loading the power grid information file into the cache, each power grid information file can be used as a node in the cache. The node types can include hierarchical data nodes (cbm), device model nodes (dev), hierarchical attribute nodes (fam), and device information nodes (node), etc., and the node types match the content stored in the power grid information file.

[0038] Specifically, by parsing the file name of the power grid information file, the node types to which the nodes matching each power grid information file in the cache belong can be directly obtained, and the nodes can be identified according to the node types. In a specific example, if the file name of the power grid information file is project.cbm, since "cbm" is included in its file name, it can be determined that the node generated by this power grid information file is a hierarchical data node, and then "cbm" can be used to generate a node identifier for this node.

[0039] The present invention creatively proposes to store the parsing results of the full-scale power grid information model in separate files according to the project hierarchy selected by the user to generate multiple single-project model files, and store all the device information and the associated information (such as attribute information, etc.) of each device at this level in the single-project model files, so that the reviewers can directly review each single-project model file, and the engineering designers can also directly modify each single-project model file, without having to perform the conversion between the power grid information model and the engineering design file multiple times, which can effectively improve the design and review efficiency.

[0040] S120. Parse each node data, obtain the identification information and data association information of each node data, and establish a hierarchical cache node tree and a device cache node tree according to the identification information and data association information of each node data.

[0041] Figure 1b It is a schematic diagram of an optional hierarchical cache node tree and a device cache node tree. As Figure 1b shown, taking the horizontal line where the dotted arrow is located as the boundary, the upper part is the hierarchical cache node tree, and the lower part is the device cache node tree.

[0042] In the hierarchical cache node tree, the fam and ifc nodes are non-essential nodes in the embodiments of the present invention and will not be further explained here. In the embodiments of the present invention, the cbm nodes in the hierarchical node tree are mainly used. In Figure 1b the shown hierarchical cache node tree, according to the structural relationship of the tree, it can be known that this hierarchical cache node tree contains three layers of nodes.

[0043] In the device cache node tree, each "dev" represents a type of device model node, and part of the information of the "dev" (such as geometric information, sub-component information, etc.) is stored in the "node" under the "dev".

[0044] Furthermore, a specific example is used to illustrate the method of establishing the hierarchical cache node tree. First, multiple node data with "cbm" included in the node identifier can be filtered out from the node data, and these node data can be used as hierarchical data nodes; then, nodes with "project.cbm" included in the node identifier are filtered out from the hierarchical data nodes, and this node is used as the top-level node of the hierarchical cache node tree; finally, the specific data content of the remaining hierarchical data nodes is analyzed, and the hierarchical cache node tree is gradually improved according to the hierarchical relationship recorded in the hierarchical data nodes (the upper-level node and the lower-level node can be recorded).

[0045] Furthermore, a specific example is used to illustrate the method of establishing the device cache node tree. First, multiple node data with "dev" included in the node identifier can be filtered out from the node data, and these node data can be used as device model nodes; then, each device model node is used as the top-level node in the device cache node tree; finally, multiple node data with "node" included in the node identifier are obtained as device information nodes, and each device information node is parsed, and the device cache node tree is gradually improved according to the device model node to which each device information node belongs.

[0046] It can be understood that the hierarchical cache node tree records the hierarchical relationship between the hierarchical data nodes in the full-scale power grid information model, and the device cache node tree records each device model node and the specific device information of each device model node. Since in the actual power transmission and transformation project, each hierarchical cache node may contain multiple types of devices, there is a certain association relationship between the hierarchical cache node tree and the device cache node tree, and this association relationship is Figure 1b shown by a dotted line in. In fact, the bottom-level nodes in the hierarchical cache node tree and the device model nodes in the device cache node tree establish an association relationship in a pointer reference manner, which is a weak association relationship (direct storage can be regarded as a strong association. Since this is a pointer reference rather than direct storage here, it is a weak association), and the way to implement this weak association relationship is through the name for association.

[0047] S130. Establish an engineering database and a device database respectively according to the hierarchical cache node tree and the device cache node tree.

[0048] Figure 1c is a schematic diagram of an optional engineering database and device database. As Figure 1cAs shown, on the left is the engineering database, and the engineering database contains the structural relationships between multiple levels and the equipment database (the equipment library is the equipment database described in the present invention, and hereinafter the equipment database will be directly used instead of the equipment library for description). On the right are multiple single-project model files. The specific generation method of the single-project model files will be further explained in step S140.

[0049] In this step, taking Figure 1c the left half of as an example, the establishment method and storage content of the engineering database and the equipment database will be specifically explained.

[0050] For the engineering database, it can be established through the hierarchical relationships between the data nodes of each level in the hierarchical cache node tree. Specifically, the top-level cbm node in the hierarchical cache node tree is the F1 level in the engineering database, the two second-level cbm nodes in the hierarchical cache node tree are respectively the F2 level 1 and F2 level 2 in the engineering database, and the four third-level cbm nodes in the hierarchical cache node tree ( Figure 1b only 3 third-level cbm nodes are shown in for example, and in this step it is assumed that the third level of the hierarchical cache node tree has 4 cbm nodes) are respectively the F3 level 1, F3 level 2, F3 level 3, and F3 level 4 in the engineering database, and the association relationship between each level is the same as the arrow connection relationship in the hierarchical cache node tree.

[0051] To better understand the relationships between the levels in the engineering database, a specific example is used for explanation here. The F1 level is generally the project information of the power transmission and transformation project. For example, the F1 level can be a substation. The F2 level is generally the system division under this project. For example, the F2 level 1 can be the input power system of the substation, and the F2 level 2 can be the output power system of the substation. Thus, it can be further understood that the F3 level is the subsystem that performs different functions under the system. For example, the F3 level 1 is a subsystem for voltage conversion under the input power system.

[0052] Continuing the previous example, each F3 level can include multiple devices that perform the functions of that F3 level. For the F3 level 1 that can be used for voltage conversion, the specific function that can be realized is to convert the input 2000V (volt) voltage into multiple 220V voltages. Then, multiple step-down transformers need to be included under the F3 level 1.

[0053] For the device database, the device database can be generated through the device model nodes in the device cache node tree. The number of dev nodes in the device cache node tree determines the number of dev devices in the generated device database. It should be noted that each dev device in the device database represents a type of device (such as DC transformers, AC transformers, etc.), rather than a specific device. Moreover, the device database also stores the geometric information, attribute information, etc. of each type of dev device according to the relationship between each dev node and each node node in the device cache node tree.

[0054] Furthermore, between each level of the engineering database in Figure 1c and the device database, there are also multiple dashed arrows. These dashed arrows represent the association relationships between each dev device and each F3 level. Such association relationships are not stored in the engineering database. The dashed lines are shown only for the convenience of understanding the embodiments of the present invention.

[0055] Next, a specific example is used to illustrate how the association relationships between each dev device and each F3 level are specifically established. First, it can be assumed that each F3 level further includes an F4 level. In the F4 level, it is recorded which dev devices are specifically used in this F3 level. However, in fact, the F4 level is not stored under the F3 level; furthermore, the F4 level is actually stored in the dev device information. By parsing the F4 stored in each dev device, it can be known which F3 levels this dev device is applied to.

[0056] S140. Obtain the hierarchical storage request sent by the user, and generate multiple single-project model files according to the engineering database, the device database, and the hierarchical storage request to achieve the hierarchical storage of the full-scale power grid information model.

[0057] The hierarchical storage request sent by the user may include the hierarchical structure to which each single-project model file belongs. Continuing with Figure 1c as an example, an optional hierarchical storage request is to generate a single-project model file under F2 level 1 ( Figure 1c the first single-project model file on the right side of the figure). At this time, the device information in F3 level 1 and F3 level 2 under F2 level 1 can be obtained, and this single-project model file can be generated according to the device information in F3 level 1 and F3 level 2.

[0058] Further, the generation method of the above single-project model file is specifically explained through an example. It can be known from the project database that under the F2 level 1, there are F3 level 1 and F3 level 2; by parsing the F4 level information stored in each dev device in the device database, it can be known that under the F3 level 1, there is dev device 1, and under the F3 level 2, there are dev device 1 and dev device 2; since dev device 1 is included under the F3 level 1, the device type of dev device 1 is added to the single-project model file, and an instance 1 of dev device 1 is generated; since dev device 1 and dev device 2 are included under the F3 level 2, and the device type of dev device 1 has already been generated in the single-project model file, an instance 2 of dev device 1 is added under the device type of dev device 1, and the device type of dev device 2 is generated in the single-project model file and an instance 1 of dev device 2 is added under the device type of dev device 2.

[0059] It should also be noted that the device type of the dev device generally stores common information such as the geometric attributes of this type of device, and the instance of the dev device generally stores the unique information of each specific device.

[0060] The technical solution of the embodiment of the present invention obtains node data by parsing the full-scale power grid information model, analyzes and processes the node data to generate a project database and a device database, and combines the hierarchical storage request sent by the user to implement the hierarchical storage method of the full-scale power grid information model. It can split the full-scale power grid information model into multiple single-project model files for storage according to user needs. The volume of each single-project model file is small but can ensure the integrity of the original information, thereby effectively improving the efficiency of model review and model modification.

[0061] Embodiment 2

[0062] Figure 2 It is a flowchart of another hierarchical storage method of the power grid information model provided by the second embodiment of the present invention. On the basis of the above embodiment, the hierarchical storage method of the power grid information model is specifically described. As Figure 2 shown, the method includes:

[0063] S210. Obtain the model identifier of the full-scale power grid information model uploaded by the user, and parse the project type corresponding to the full-scale power grid information model according to the model identifier.

[0064] In a specific example, if the model identifier of the full-scale power grid information model includes GIMPKGS, the corresponding co-layer type of the full-scale power grid information model is a substation project; if the model identifier of the full-scale power grid information model includes GIMPKGT, the corresponding co-layer type of the full-scale power grid information model is a line project; if the model identifier of the full-scale power grid information model includes GIMPKEC, the corresponding co-layer type of the full-scale power grid information model is a cable line project.

[0065] S220. Analyze the full-scale power grid information model uploaded by the user to obtain multiple power grid information files in the full-scale power grid information model.

[0066] S230. Read each power grid information file, load the data information of each power grid information file into the cache to generate multiple node data in the cache, and identify each node data using the file name of each power grid information file.

[0067] S240. According to the identification information of each node data, obtain the first type of node data and the second type of node data in the cache, and respectively screen out the first type of top-level node data and the second type of top-level node data from the first type of node data and the second type of node data.

[0068] Among them, the first type of node data may include hierarchical data nodes and attribute nodes related to the hierarchical data nodes, etc. In a specific example, the first type of node data can be identified according to the node identifier. If the node identifier contains preset node identifiers such as cbm, fam, and ifc, these nodes can be identified as the first type of node data; similarly, the second type of node data may include device model nodes and device information nodes, etc. In a specific example, the second type of node data can be identified according to the node identifier. If the node identifier contains preset node identifiers such as dev and node, these nodes can be identified as the second type of node data.

[0069] Continuing with the previous example, the node data whose node identifier contains project.cbm can be identified in the first type of node data as the first type of top-level node data; the node data whose node identifier contains dev can be identified in the second type of node data as the second type of top-level node data.

[0070] S250. Establish a hierarchical cache node tree according to the data association information of the first type of top-level node data and each first type of node data.

[0071] Optionally, due to the negligence of designers or errors in the parsing process of the full-scale power grid information model, there may be cases of missing information. For example, some of the fam attribute information under the cbm node is missing. However, for some fixed data information, it can be queried and obtained in the standard format library of the power grid information model. Therefore, after establishing the hierarchical cache node tree, the information in the hierarchical cache node tree can also be checked. If there is missing information, it can be searched and obtained in the standard format library, and the missing information in the hierarchical cache node tree can be supplemented.

[0072] S260. Establish an equipment cache node tree according to the data association information of the second type of top-level node data and each second type of node data.

[0073] Among them, the hierarchical cache node tree and the equipment cache node tree each include at least one level. Each level of the hierarchical cache node tree includes at least one first type of node data, and there is a corresponding relationship between each first type of node data and each project in the full-scale power grid information model. Each level of the equipment cache node tree includes at least one second type of node data.

[0074] There is no specified execution order relationship between step S250 and step S260. It is also possible to execute S260 first and then S250. In order to facilitate the understanding of the technical solution of the present invention, this embodiment provides an optional execution order relationship, but it is not limited thereto.

[0075] S270. Obtain each first type of bottom-level node data serving as the bottom-level node in the hierarchical cache node tree.

[0076] S280. Obtain the device information storage nodes associated with each first type of bottom-level node data, and according to the device name information stored in each device information storage node, obtain at least one second type of top-level node data associated with each first type of bottom-level node data in the equipment cache node tree.

[0077] Optionally, the device information storage nodes associated with each first type of bottom-level node data are the F4 level nodes mentioned in the foregoing example. The device information storage nodes can be screened out by parsing the specific content of each node data. The device information storage nodes record the dev device types under the first type of bottom-level node data associated with them.

[0078] S290. Store the association relationship between each first type of bottom-level node and each second type of top-level node.

[0079] S2100. Obtain the node hierarchical relationship between each first type of node data in the hierarchical cache node tree, and establish an engineering database according to the node hierarchical relationship between each first type of node data and the pre-set engineering database establishment rules.

[0080] Among them, the engineering database stores the engineering hierarchical relationships among various projects in the full-scale power grid information model, and the establishment rules of the engineering database match the project types of the full-scale power grid information model.

[0081] S2110. Obtain the node hierarchical relationships among the second-type node data in the device cache node tree, and establish a device database according to the node hierarchical relationships among the second-type node data.

[0082] Among them, the device database stores the device information of each device in the full-scale power grid information model.

[0083] Specifically, the device information of each device in the full-scale power grid information model may include device type information, geometric attribute information of the device, etc.

[0084] Optionally, it is known that the node data in the foregoing steps is obtained from the cache. After the engineering database and the device database are established, the node data content has been stored in each database. At this time, the cache can be released to reduce space occupancy.

[0085] S2120. According to the association relationships between each first-type bottom-layer node and each second-type top-layer node in the hierarchical cache node tree and the device cache node tree, obtain the association relationships between each bottom-layer project in the engineering database and each device information in the device database.

[0086] S2130. Obtain the hierarchical storage request sent by the user, and obtain the engineering hierarchy of each single-project model file according to the hierarchical storage request.

[0087] S2140. According to the engineering hierarchical relationships among the projects in the engineering database and the association relationships between each bottom-layer project in the engineering database and each device information in the device database, obtain the device information associated with each engineering hierarchy of each single-project model file.

[0088] S2150. Generate multiple single-project model files according to the engineering hierarchy of each single-project model file and the device information associated with each engineering hierarchy of each single-project model file.

[0089] Among them, generating multiple single-project model files according to the engineering hierarchy of each single-project model file and the device information associated with each engineering hierarchy of each single-project model file may specifically include:

[0090] Judge whether the device type unit of the target device is stored in the single-project model file;

[0091] If so, add a device instance unit to the single-project model file according to the device information of the target device;

[0092] Otherwise, extract the type information from the device information of the target device, add a device type unit that matches the target device to the single-project model file, and add a device instance unit to the single-project model file according to the device information of the target device.

[0093] The technical solution of the embodiment of the present invention can ensure the integrity of the information in the hierarchical cache database by checking whether there is missing information in the hierarchical cache node tree after establishing the hierarchical cache node tree and supplementing the missing information in the hierarchical cache node tree using the standard format library. By releasing the cache after establishing the project database and the device database, it can effectively reduce the space occupation. By determining whether the device type unit of the target device is stored in the single-project model file and adding a device instance unit to the stored device type unit, it can minimize the stored content of the single-project model file and reduce the volume.

[0094] Embodiment III

[0095] Figure 3 It is a schematic structural diagram of a hierarchical storage device for a power grid information model provided by Embodiment III of the present invention. As Figure 3 shown, the device includes: a node data generation module 310, a node tree establishment module 320, a database establishment module 330, and a power grid information model hierarchical storage module 340.

[0096] The node data generation module 310 is used to parse the full-scale power grid information model uploaded by the user, obtain multiple power grid information files in the full-scale power grid information model, and generate multiple node data in the cache using the power grid information files.

[0097] The node tree establishment module 320 is used to parse each node data, obtain the identification information and data association information of each node data, and establish a hierarchical cache node tree and a device cache node tree according to the identification information and data association information of each node data.

[0098] The database establishment module 330 is used to establish a project database and a device database respectively according to the hierarchical cache node tree and the device cache node tree.

[0099] The power grid information model hierarchical storage module 340 is used to obtain the hierarchical storage request sent by the user, and generate multiple single-project model files according to the project database, the device database, and the hierarchical storage request, so as to realize the hierarchical storage of the full-scale power grid information model.

[0100] The technical solution of the embodiment of the present invention obtains node data by parsing the full-scale power grid information model, analyzes and processes the node data to generate an engineering database and an equipment database, and combines the hierarchical storage request sent by the user to implement the hierarchical storage method of the full-scale power grid information model, which can split the full-scale power grid information model into multiple single-project model files for storage according to user needs. The volume of each single-project model file is small but can ensure the integrity of the original information, thus effectively improving the efficiency of model review and model modification.

[0101] Based on the above embodiments, the node data generation module 310 may specifically be used for:
