Description

Technical Field

[0001] The present invention belongs to the technical field of smart grids, and more specifically, relates to a method and system for constructing a historical state architecture of a digital distribution network operating system. Background Art

[0002] Multi-dimensional historical power grid data includes multi-dimensional historical data such as historical power grid power flow, historical operation measurements, historical environmental measurements, and historical meteorology, which constitute the spatio-temporal big data of the power grid. As the core framework of the multi-dimensional historical power grid data system, historical grid structure data is the main carrier of the spatio-temporal coordinates of the historical state digital power grid. During the operation of the power grid, equipment change operations such as switch opening and closing occur frequently, making the historical grid structure data present the characteristics of being massive, high-dimensional, and non-linearly correlated.

[0003] Large-scale power grid data sets and the data characteristics recorded therein are the core driving forces for the development and application of power grid neural network models. The data changes of grid structure equipment in the power system occur discretely in the vast space of the power transmission, transformation, and distribution business sites in each province. Due to imperfect data sharing mechanisms, immature historical state power grid models, imperfect data maintenance modes, and non-standard data encryption, there are problems such as difficult data acquisition, low data quality, lack of data standards, and difficult data security guarantee for real power data. As a result, it is difficult for relevant institutions to apply the sufficient real historical power grid data at the business site, and the scarcity of research data sets has become a restrictive factor for the development and application of power artificial intelligence.

[0004] The prior art document 1 (CN116975399B) discloses a method and system for displaying a historical state power grid geographical map. Its disadvantage is that there is no data update mechanism for newly collected on-site equipment data and the existing operating state grid structure data and historical state grid structure data in the current system, and it is impossible to obtain updated data from the system in a timely manner after the data is updated. Summary of the Invention

[0005] To solve the deficiencies in the prior art, the present invention provides a method and system for constructing a historical state architecture of a digital distribution network operating system. By collecting equipment change operation data at the business site, maintaining the data for various equipment operation types, storing the equipment change operation data in a unified model, a complete historical state power grid data is constructed and the historical grid structure data is synchronized in real time to achieve data sharing.

[0006] The present invention adopts the following technical solutions.

[0007] The first aspect of the present invention proposes a method for constructing a historical state architecture of a digital distribution network operating system, including:

[0008] Collecting equipment change operation data at the business site through a homologous maintenance application;

[0009] Preprocess the collected device change operation data;

[0010] Store the preprocessed data in a unified model to obtain a total historical grid dataset. The unified model includes an editing-state power grid model, an operating-state power grid model, and a historical-state power grid model;

[0011] A third-party data-driven algorithm requests the historical grid dataset at a specified historical moment in the unified model for calculation to obtain a calculation result;

[0012] Merge the calculation result with the total historical grid dataset, and then merge the obtained merged result with the geographical feature dataset to obtain a historical grid geographical map;

[0013] Cut the historical grid geographical map into historical-state vector tiles and transmit them to the digital display of each network province business application to realize the construction of the historical-state architecture of the digital distribution network operation system.

[0014] Preferably, collect device change data at the business site through a homologous maintenance application, specifically including:

[0015] When the staff in each province execute device change tasks, through the homologous maintenance applications of the transmission, substation, and distribution versions, according to the data entry specifications, enter the device change operation data in the grid device change task into the homologous maintenance application to obtain the device change operation data.

[0016] Preferably, the device change operation data includes the device change operation type, the completion time of the change operation, and the change operation spatial coordinates.

[0017] Preferably, the device change operation type includes new commissioning, change, and retirement,

[0018] Among them, during the device change operation of the new commissioning operation type, the homologous maintenance application notifies the staff to input the device ledger and the device topological relationship;

[0019] During the device change operation of the change operation type and the retirement operation type, the homologous maintenance application obtains the original device ledger and topological relationship data of the changed device in the system, and modifies the original device ledger and topological relationship data according to the change operation to generate a new device ledger and topological relationship.

[0020] Preferably, preprocess the collected grid device change data, specifically including:

[0021] Topological connectivity and ledger integrity verification, management personnel review, data cleaning, and data unification.

[0022] Preferably, store the preprocessed data in the unified model, specifically including:

[0023] When business personnel enter device change operation data, multiple edit drafts are created during the entry process of the device change task. Each draft generates an edit version, and different edit versions are distinguished by the edit version number. All different edit versions are stored in the edit-state power grid model. After the business personnel complete a complete edit version of a device change task, this edit version is submitted for review. After the review is passed, this edit version is officially released in the edit-state power grid model;

[0024] After the official release, multiple device change records in this edit version are synchronized from the edit-state power grid model to the running-state power grid model, and the device data in the running-state power grid model is updated to the latest state;

[0025] The device data before the update in the running-state power grid model is inherited into the historical-state power grid model, and the total historical grid framework dataset is obtained from the historical-state power grid model. Among them, the total historical grid framework dataset records the historical grid framework status of each minute in the past.

[0026] Preferably, the storage of different device change operation type data in the unified model specifically includes:

[0027] During the device change operation of the newly commissioned operation type, a new device record is generated in the running-state power grid model for the device ledger data and topological relationship data of the newly commissioned device recorded in the edit-state device change data of the edit-state power grid model, and the change operation type, change operation time, and change operation space coordinate data in the edit-state device change data are generated into a new historical device change record and stored in the historical-state power grid model;

[0028] During the device change operation of the change operation type, the new device state recorded in the edit-state device change data of the edit-state power grid model replaces the original device state of this device in the running-state power grid. The original device state data being replaced, combined with the change operation type, change operation time, and change operation space coordinates saved in the edit-state device change data, generates a new historical device change record and is stored in the historical-state power grid model;

[0029] During the device change operation of the decommissioning operation type, the device data of this device is found and deleted in the running-state power grid model, and the change operation type, change operation time, and change operation space coordinate data recorded in the edit-state device change data are generated into a new historical device change record and stored in the historical-state power grid model.

[0030] Preferably, the third-party data-driven algorithm requests the historical grid framework dataset at a specified historical moment in the unified model for calculation to obtain the calculation result, specifically including:

[0031] The third-party application requests the historical grid framework dataset at a specified historical moment from the unified model;

[0032] After the requested historical grid dataset is encrypted within the system using the DES encryption algorithm, it is transmitted over the network to a third-party application;

[0033] The third-party application uses the DES decryption algorithm provided by the system to decrypt the encrypted historical grid dataset;

[0034] The decrypted historical grid dataset is transmitted to the corresponding third-party data-driven algorithm for operation to obtain an operation result;

[0035] The third-party application then uses the DES encryption algorithm to encrypt the operation result data and transmits the encrypted data over the network to the system.

[0036] Preferably, the operation result is merged with the total historical grid dataset, and the obtained merged result is further merged with the geographical feature dataset to obtain a historical grid geographical map, specifically including:

[0037] The system decrypts the encrypted data transmitted by the third-party application using the DES decryption algorithm, performs a verification operation on the decryption result to obtain third-party data;

[0038] The front-end user sets the sparsity level, performs data verification and data sparsity on the historical grid data in the historical power grid model to obtain processed historical grid data;

[0039] The third-party data and the processed historical grid data are merged, and the merged result is merged with the geographical feature database to generate a historical grid geographical map.

[0040] The second aspect of the present invention proposes a historical state architecture construction system for a digital distribution network operation system, which runs the above-mentioned historical state architecture construction method for a digital distribution network operation system, including:

[0055] Figure 1 is a schematic diagram of the historical state digital power grid graphic-model-data unified service architecture provided according to an embodiment of the present invention. Detailed implementation manners

[0056] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions of the present invention with reference to the accompanying drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the spirit of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0057] As Figure 1 shown, Embodiment 1 of the present invention provides a method for constructing a historical state architecture of a digital distribution network operation system, including the following steps:

[0058] The architecture of the historical state digital power grid graph-model-data unified service is as Figure 1 shown, and includes three unified and interconnected services: graphical display of grid data at historical moments, unified model, and data maintenance. Among them, the graph refers to the historical grid geographical map, which is the appearance of the historical state digital power grid, and its function is to intuitively, multi-dimensionally, and interactively display the historical state digital power grid information; the model refers to the historical state power grid model, which is the skeleton of the historical state digital power grid and can efficiently organize, refine, and transmit the historical state grid data; the data refers to the multi-source heterogeneous historical grid data, which is the entity of the historical state digital power grid, can drive graphical display and model calculation, and support the development of power grid services.

[0059] Step 1: Collect the device change operation data at the business site through the homologous maintenance application.

[0060] The data maintenance service collects the grid device change operation data generated at the physical power grid transmission, transformation, and distribution business sites through the homologous maintenance application.

[0061] When the staff in each province execute the device change task, through the homologous maintenance applications of the three versions of transmission, transformation, and distribution, and according to the data entry specifications, the device change operation data included in the device change task is entered into the homologous maintenance application to obtain the device change operation data.

[0062] The device change operation data includes the device change operation type, the completion time of the change operation, and the spatial coordinates of the change operation.

[0063] The types of change operations include ① new commissioning, ② change, and ③ decommissioning. Each equipment change operation corresponds to a primary equipment change of a piece of equipment. During the equipment change operation of the new commissioning operation type, the homologous maintenance application will require the staff to input the specific equipment inventory and equipment topological relationship. During the equipment change operation of the change and decommissioning operation types, the homologous maintenance application will find the original equipment inventory and topological relationship of the changed equipment in the system, modify the original equipment data according to the change operation, and generate new equipment inventory and topological relationship. Thus, the equipment change operations occurring in the physical power grid are synchronized to the digital power grid. Step 2: Preprocess the equipment change operation data collected in Step 1.

[0064] After the equipment change operation data passes through the preprocessing operations of topological connectivity and inventory integrity verification, management personnel review, data cleaning, and data unification, it is centrally stored in the grid resource business mid-platform to achieve multi-source real-time collection of historical grid data.

[0065] Step 3: Store the preprocessed data in a unified model to obtain the total historical grid dataset. The unified model includes the editing-state power grid model, the operation-state power grid model, and the historical-state power grid model.

[0067] The unified model includes the operation-state power grid model, the historical-state power grid model, and the editing-state power grid model. The operation-state power grid model is used to record the current in-operation grid data; the historical-state power grid model is used to record the grid data at all historical moments; the editing-state power grid model records the grid data that has changed in the physical power grid but has not been officially released. Through the three models and their interaction mechanisms, it is possible to ensure the close connection and efficient storage of the grid data of the physical power grid, the operation-state digital power grid, and the historical-state digital power grid, and provide the historical grid data to other services and applications through a unified interface.

[0068] The operation-state digital power grid and the historical-state digital power grid are two states of the digital power grid at different grid times and should be maintained, managed, and applied as a unified whole. After the equipment change operation is actually performed on-site in the business, the operation-state grid equipment data in the operation-state power grid model should be able to be updated to the latest equipment state in real time with the equipment change operation, and the replaced equipment data should be inherited into the historical-state grid data. The total historical grid dataset is obtained from the historical-state power grid model, where the total historical grid dataset records the historical grid states of the past every minute. The data, model, and graphics of the historical-state power grid need to be closely associated with the operation-state power grid.

[0069] The digital power grid is the digital twin of the physical power grid and is an accurate mapping of the physical power grid. The grid data is generated from the discrete business sites of the physical power grid. After the business personnel perform multiple equipment change operations in a device change task, all the device change operation data included in this device change task is entered into the homologous maintenance application, and the device change data will be saved in the editing-state power grid model. When the business personnel enter the device change data, multiple edit drafts may be created during the data entry process for a relatively complex device change task. Each draft will generate an edit version, and different edit versions are distinguished by the edit version number. These different edit versions are all stored in the editing-state power grid model.

[0070] After the business personnel complete the perfect edit version of a device change task, this version is submitted for review. After the review is passed, this edit version will be officially released. After the official release, multiple device change records included in this edit version will be synchronized from the editing-state model to the running-state digital power grid to update the device data in the running-state digital power grid to the latest state.

[0071] The storage of data of different device change operation types in the unified model is specifically as follows:

[0072] For the "newly put into operation" change type, the device ledger data and topological relationship data of the newly put into operation device recorded in the editing-state device change data will generate a new device record in the running-state power grid model, and the change operation type, change operation time, and change operation space coordinate data in the editing-state device change data will generate a new historical device change record and be stored in the historical-state power grid model;

[0073] For the "change" change type, the new device state recorded in the editing-state device change data will replace the original device state of this device in the running-state power grid, and the replaced original device state data will be combined with the change operation type, change operation time, and change operation space coordinate saved in the editing-state device change data to generate a new historical device change record and be stored in the historical-state power grid model;

[0074] For the "retirement" change type, the device data of this device will be found and deleted in the running-state power grid model, and the change operation type, change operation time, and change operation space coordinate data recorded in the editing-state device change data will generate a new historical device change record and be stored in the historical-state power grid model.

[0075] The scale of the full physical power grid data is huge. Taking Jiangsu Province as an example, in 2024, Jiangsu Province already had 200 million pieces of equipment data, with an average of 340 million times of equipment data changes per month. The measurement system would record the power grid operation status data as a whole every 5 - 15 minutes. To completely and accurately preserve the spatio-temporal characteristics and spatio-temporal joint correlation of the power grid spatio-temporal big data, it was necessary to record the historical grid data in the physical power grid at different historical moments with a minute-level time resolution. The historical grid at each historical moment was a complete grid data set, and a new historical grid data set would be generated every minute. The data scale would soar over time, and the traditional historical power grid data model for small-scale grids was no longer applicable. It was necessary to design a historical digital power grid model that took into account both storage efficiency and data spatio-temporal integrity.

[0076] The historical power grid model records the historical grid status of each minute in the past, including the historical equipment ledger and topological relationship data of each grid equipment in the historical grid.

[0077] Step 4: The third-party data-driven algorithm requests the historical grid data set at the specified historical moment in the unified model for operation to obtain the operation result.

[0078] The third-party driven algorithm requests the historical grid data set at the specified historical moment in the unified model for operation to obtain the operation result, specifically including:

[0079] The third-party application requests the historical grid data set at the specified historical moment from the unified model;

[0080] The requested historical grid data set is encrypted by the DES encryption algorithm in the system and then transmitted to the third-party application through the network;

[0081] The third-party application uses the decryptor provided by the system to decrypt the encrypted historical grid data set using the DES decryption algorithm;

[0082] The decrypted historical grid data set is transmitted to the corresponding third-party driven algorithm for operation to obtain the operation result;

[0083] The third-party application then encrypts the operation result data using the DES encryption algorithm and transmits the encrypted data to the system through the network.

[0084] Third-party data-driven algorithms, such as intelligent planning, power generation prediction, fault prediction, fault warning, and load prediction algorithms, need to use the historical grid dataset at a specified historical moment as the operation dataset to obtain the target operation result. To ensure data encryption during transmission, the historical grid dataset requested by the third-party data-driven algorithm will be encrypted within the system using the DES encryption algorithm and then transmitted to the third-party application via the network. The third-party application can only obtain the correct historical grid dataset by decrypting the encrypted historical grid dataset using the DES decryption algorithm through the decryptor provided by this system. After the third-party data-driven algorithm performs operations based on the historical grid dataset and obtains algorithm results such as power generation prediction results and load prediction results, it uses the encryptor provided by this system to encrypt the operation result data using the DES encryption algorithm and then transmits the encrypted data to this system via the network.

[0085] Step 5: Merge the operation result with the total historical grid dataset, and then merge the obtained merged result with the geographical feature dataset to obtain the historical grid geographical map dataset, specifically including:

[0086] The system decrypts the encrypted data transmitted by the third-party application using the DES decryption algorithm, performs a verification operation on the decryption result to obtain the third-party data;

[0087] The front-end user sets the sparsity level, performs data verification and data sparsity on the historical grid data in the historical state power grid model to obtain the processed historical grid data;

[0088] Merge the third-party data and the processed historical grid data, and then merge the merged result with the geographical feature database to generate the historical grid geographical map dataset.

[0089] Decrypt the encrypted data transmitted by the third-party data-driven algorithm using the DES decryption algorithm to obtain operation results such as power generation prediction and load prediction, and perform a verification operation on the operation results to ensure data quality. Perform data verification and data sparsity on the historical grid data in the historical state power grid model, and the sparsity level is set by the front-end user. Merge the operation result with the historical grid data, and merge the predicted device status data in the operation result into the corresponding device status data in the historical grid data to generate the historical grid device dataset. Geographical feature data such as roads, mountains, and rivers are stored separately in the geographical feature database, and the historical grid geographical map is generated after the historical grid device dataset is merged with the geographical feature dataset.

[0090] Step 6: Cut the historical grid geographical map into historical state vector tiles, and provide the geographical map to the digital display of the business applications of each network province by transmitting a small-scale tile set, so as to realize the construction of the historical state architecture of the digital distribution network operation system, thereby reducing the data transmission volume and improving the concurrent service ability.

[0091] The historical grid framework graphic display service needs to respond to concurrent requests for the historical grid geographical map from different business applications of the headquarters and multiple network provinces. Currently, the average monthly call times of each network province for the running state graphic display service are about tens of millions to over hundreds of millions of times.
