[0048] Figure 1 A schematic flow chart of a real-time library downloading method provided by the present application is shown, which specifically includes the following steps.

[0049] S101, when the power grid dispatching system is started, the real-time library download service is run to obtain the preset real-time library instructions from the relationship library.

[0050] Among them, the real-time library is one of the core modules of the industrial control system. It uses the computer system memory as the main storage medium to provide a high-speed and efficient database access interface for the application module. In the power system, the application of the real-time library is particularly important. It can meet the needs of the power grid dispatching system for fast data access, real-time monitoring and early warning, and online analysis. Therefore, the real-time library has become an indispensable part of the power grid dispatching system. In the power system, the power grid model data is stored in the relational library. The real-time library is formed from the relational library through the download process. The download process is the generation process of the real-time library.

[0051] The real-time database contains power grid models, substation models, dispatching rules, alarm information, event records, real-time operation data, etc. The real-time database is the basis for the power grid dispatching system to analyze and interact with power grid intelligent devices. The power grid model, substation model and other power grid model data in the real-time database usually come from the power grid model configuration tool. The power grid model (also called power grid model data) configuration process is an offline configuration method. The field staff creates the power grid model through the configuration tool and saves it in the relationship database. When the power grid dispatching system is run for the first time, the power grid model will be downloaded from the relationship database to the real-time database.

[0052] Among them, the real-time library download service is a key component in the power grid dispatching system, responsible for importing the power grid model data in the relational library (also called relational database) into the real-time library. This service is usually run when the power grid dispatching system is started to ensure that the real-time library (also called real-time database) has the latest power grid model data for the system to use.

[0053] Among them, the real-time library instructions are a set of instructions used in the power grid dispatching system to guide the download of power grid model data to the real-time library. These instructions are generated after the power grid model data is processed and optimized and stored in the relationship library. The purpose is to improve the efficiency and speed of importing power grid model data into the real-time library.

[0054] Optionally, the real-time library instructions may include but are not limited to the following:

[0055] Identification: Specifies which power grid model data needs to be imported into the real-time library, including identification information such as the source, type, and timestamp of the data.

[0056] Data structure and format: defines how the power grid model data is organized in the real-time library, including data model, fields, data types, length, etc.

[0057] Operation instructions: including specific instructions for operations such as loading, updating, and deleting data.

[0058] Optionally, conversion rules may also be included: if the data needs to be converted from one format to another, the instructions contain these conversion rules.

[0059] In an embodiment of the present application, when the power grid dispatching system is started, the real-time library download service is run, and the pre-generated real-time library instructions are obtained from the relationship library based on the real-time library download service.

[0060] Optionally, in one embodiment, the process of generating the real-time library instruction includes:

[0061] a. Cut the first power grid model data and create table structure information.

[0062] Among them, the relational database is designed first, including table structure, data type, index, primary key and foreign key, etc. The relational database is used to store the power grid model data. In addition, a real-time library instruction table is pre-designed to store the instruction set required for downloading the power grid model data. Then, the real-time library data dictionary is defined, and according to business needs, the real-time library data dictionary configuration tool is used to cut out the required data (including specific tables, fields, data types and data lengths, etc.) from the first power grid model data, and the table structure information of the cut data is defined in the relational library. The table structure information includes creating a database table, specifying field names, data types, indexes, etc., to facilitate data storage and retrieval.

[0063] b. Parsing the imported power grid model file, and mapping the parsing result to the relationship library based on the table structure information to generate second power grid model data.

[0064] Among them, the power grid model file is imported based on the power grid model tool, and the primary system configuration, secondary system configuration, communication network and parameter configuration are parsed to obtain the parsed data (i.e., the parsing result above). After that, the parsed data is mapped to the relational library based on the table structure information to generate the second power grid model data. This mapping process involves converting the entities and relationships in the power grid model file into table structures and records in the relational library.

[0065] The power grid model files include a Substation Configuration Description (SCD) file and a Common Information Model (CIM) file.

[0066] Among them, the power grid model tool extracts relevant information from the power grid model file according to different business types and stores it in the relationship library, and supports the modification and viewing functions of the power grid model data.

[0067] c. Based on the real-time library data dictionary, convert the second power grid model data into the real-time library instructions, and store them in the real-time library instruction table in the relationship library.

[0068] The real-time library data dictionary is a configuration file that describes the mapping relationship between the power grid model data required by the business application and the real-time library. The mapping relationship includes table information, table field information, data type, data length and other information. Based on the real-time library data dictionary, it can be clearly defined which tables and fields need to be imported, as well as their data types and lengths. The real-time library data dictionary simplifies the coupling between the business system and the power grid model configuration, allowing the system to quickly respond to changes in business needs.

[0069] The real-time database data dictionary is stored in a sqlite file, Table 1 is the real-time data table information, and Table 2 is the real-time data table structure.

[0070] Application Number Real-time database table name Keyword column Database table name Loading conditions Table Classification 401 CfgSignModel id CfgSignModel 1=1order by id System Class 401 UserInfo id UserInfo 1=1order by id System Class

[0071] Table 1

[0072] Table No. Real-time database domain name Database domain name Real-time database table name Data Types Data length Column Type 403 ID id CfgSignModel int 0 0 404 SignName signname CfgSignModel string 0 0

[0073] Table 2

[0074] According to the real-time library data dictionary, the second power grid model data is converted into a real-time library instruction, which includes the location, format, loading method, storage method of the data in the real-time library, etc. The real-time library instruction contains the metadata of the data, which is used to guide the real-time library download service to extract and load the required power grid model data from the relational library. In this way, the efficiency and accuracy of data loading can be improved.

[0075] Afterwards, the generated real-time library instructions are stored in binary form in the real-time library instruction table in the relational library. These instructions can be directly read and executed when the power grid dispatching system is started or the power grid model data needs to be updated. Figure 2 shown.

[0076] The first power grid model data generally refers to original and complete power grid model data, which may include all power grid entities, attributes, relationships and configuration information. The first power grid model data may include a large amount of detailed information, but not all information needs to be used in real time.

[0077] The second power grid model data refers to the processed and optimized power grid model data, which has been tailored and converted according to the needs of the real-time library. Specifically, it is mapped and converted according to the rules in the real-time library data dictionary and is ready to be imported into the real-time library. For example, it may only contain key data required for real-time monitoring and analysis.

[0078] In an optional embodiment, the first power grid model data includes at least one of the following: power grid topology, equipment static parameter information, power grid operation data, geographic information, meteorological data, load model data, and real-time measurement data.

[0079] In the power grid dispatching system, the power grid model is a way of expressing data instantiation of the physical power grid. The power grid model data is a collection of data describing the power grid according to the rules of the power grid model. The power grid model configuration refers to the settings and definitions made when creating the power grid model. The purpose is to generate real-time library instructions in advance while generating the power grid model data.

[0080] The first power grid model data includes at least one of the following:

[0081] The grid topology includes the connection relationship and network topology of substations, lines, transformers, circuit breakers, disconnectors and other equipment.

[0082] Equipment static parameter information, including equipment rated parameters, physical characteristics, and operating limitations.

[0083] Grid operation data, including the real-time operating status of equipment, such as voltage, current, power, and frequency.

[0084] Geographic information, including the geographical location information of power grid equipment, such as longitude and latitude, plant type, etc.

[0085] Meteorological data, including meteorological information related to power grid operation, such as temperature, wind speed, humidity, etc.

[0086] Load model data is data that describes the load characteristics of the power system, including different types of load models and parameters.

[0087] Real-time measurement data, such as Phasor Measurement Unit (PMU) data and Supervisory Control And Data Acquisition (SCADA) data.

[0088] In order to facilitate the use of these data in different applications of the power system, the SCD file is used in the power grid dispatching system to describe the configuration and communication settings of the substation, and the CIM file is used to describe the various entities in the power system and the relationships between them.

[0089] S102, parsing the real-time library instruction to obtain target power grid model data.

[0090] The plug-in is called to parse the real-time library instruction to obtain the parsing result, which includes information such as the location, format, loading method, and storage method of the data in the real-time library. The target power grid model data is obtained from the relationship library based on the parsing result. In this way, during the download process, the real-time library can directly read the target power grid model data from a predetermined location according to the parsing result without the need for complex query and retrieval operations.

[0091] S103, importing the target power grid model data into a real-time database.

[0092] In the embodiment of the present application, after the target power grid model data is acquired from the relationship library, a stable connection with the real-time library is established to transmit the data from the relationship library to the real-time library.

[0093] Optionally, the target power grid model data acquired by the relational database already meets the format requirements of the real-time database, and no further data assembly is required.

[0094] In an embodiment of the present application, when the power grid dispatching system is started, the real-time library download service is run, the preset real-time library instructions are obtained from the relationship library, the plug-in is called to parse the real-time library instructions, and the download statements that can be recognized by the real-time library are generated according to the real-time library data dictionary, that is, the target power grid model data is obtained, and the target power grid model data is imported into the real-time library. Through the preset real-time library instructions, the delay in data query and processing is reduced, so that the power grid dispatching system can respond to changes in the power grid status more quickly. In addition, the preset real-time library instructions provide flexible data processing capabilities that can adapt to different data updates and system upgrade requirements. In addition, based on the above scheme, system maintenance and expansion become easier, and new data types and models can be quickly integrated into the system.

[0095] In an optional embodiment, before importing the target power grid model data into the real-time library, it also includes: performing an import preprocessing operation on the target power grid model data; wherein the import preprocessing operation includes at least one of the following: data verification, data conversion, data cleaning, and data assembly.

[0096] Among them, before being transmitted to the relationship database, the target power grid model data is verified to check the integrity, accuracy and consistency of the data.

[0097] If the format of the target power grid model data does not match the requirements of the real-time library, data conversion is performed to adapt to the data model of the real-time library, including unit conversion, data type conversion, structure adjustment, etc.

[0098] Among them, data is cleaned to remove duplicate records, erroneous data or incomplete information to ensure the quality of data imported into the real-time library.

[0099] The target power grid model data may be from multiple data sources or data fragments. Therefore, after being imported into the real-time library, it is necessary to assemble the multiple data sources or data fragments into a complete data set according to the data model of the real-time library, including building relationships between data and creating data sets.

[0100] Optionally, monitor the progress and status of the data import to ensure that the data is loaded correctly into the live library.

[0101] Optionally, if any errors are encountered during the import process, implement error handling mechanisms to attempt to resolve the issues or roll back the operation.

[0102] Optionally, after the data is imported, a data check is performed to ensure that the data is consistent with the source data and meets the requirements of the real-time database.

[0103] After the power grid model data is downloaded to the real-time database, there are updates to the power grid model data, such as adding new plants and stations, adding new primary / secondary equipment. In order to avoid the shutdown of the power grid dispatching system, the power grid model data is generally updated by online publishing. Figure 3 A schematic flow chart of a real-time library update method provided by the present application is shown, which specifically includes the following steps.

[0104] S301 : In response to a modification operation on power grid model data in a relationship library, an update notification and a real-time library update instruction are generated.

[0105] S302: After receiving the update notification, the real-time library download service parses the real-time library update instruction to obtain the power grid model data to be updated.

[0106] S303: Import the to-be-updated power grid model data into the real-time database.

[0107] Among them, during the operation of the power grid dispatching system, when the power grid model data in the relationship library changes and needs to be released, the changed part of the power grid model data will be downloaded from the relationship library to the real-time library again to realize the online update of the power grid model data in the real-time library.

[0108] In the embodiment of the present application, the power grid model tool is used to modify the power grid model data in the relationship library online, the plug-in is called to generate the change data and update notification, and the real-time library update instruction is generated based on the change data. After that, the update notification is published to the real-time library download service through the message bus. After receiving the update notification, the real-time library download service calls the plug-in to parse the real-time library update instruction and obtains the power grid model data to be updated stored in the relationship library. After that, the power grid model data to be updated is transmitted to the real-time library.

[0109] The real-time library update instruction and the above-mentioned real-time library instruction refer to the same type of instruction, but the real-time library update instruction emphasizes more on the instruction for updating the data in the real-time library.

[0110] Optionally, a model change table may be generated to store the real-time library update instruction. After receiving the update notification, the real-time library download service obtains the model change table, calls the plug-in to parse the real-time library update instruction, and updates the data.

[0111] In an embodiment of the present application, real-time library instructions are generated while the power grid model data is saved, reducing the process of reading the power grid model data and assembling the data during the real-time library download process, realizing functions such as rapid startup of the power grid dispatching system and rapid online update of the power grid model data, and accelerating the system's failure recovery capability.

[0112] In order to facilitate the understanding of the download and update process, here is combined Figure 4This flowchart is to show how the power grid model data is processed and imported into the real-time library for use by the power grid dispatching system. Each real-time library instruction may contain specific data operation instructions, such as instructions for inserting, updating or deleting power grid model data. The power grid model tool generates or updates the power grid model data, and at the same time, the pre-generated real-time library instructions are also created or updated. The real-time library download service reads these pre-generated real-time library instructions from the relational database. Based on the pre-generated plug-in (i.e. the plug-in mentioned above), these instructions are parsed to obtain the required power grid model data, and the real-time library download service imports the required power grid model data into the real-time library.

[0113] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.
