[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0041] A data interaction system for supporting different container groups, including a demand acquisition module, a cloud-edge interaction management module, a test optimization module, a human-computer interaction module, and an API interface. Its specific functions are:
[0042] The requirements acquisition module is used to obtain indicators through literature research and field investigations, and to clarify the requirements of the data interaction system;
[0043] The cloud-edge interaction management module is responsible for scheduling communication and data interaction between the cloud and edge clusters, including the registration management unit, the base service unit, the application interaction service unit, and the edge cluster monitoring center;
[0044] The test optimization module is used to perform real-time detection of data interaction quality. The monitoring factors of data interaction quality include power imbalance detection value, current imbalance detection value, voltage detection value, intelligent detection value, and error detection value. A data interaction delay detection model is established. The formula of the data interaction delay detection model is:
[0045]
[0046] Where: GMN is the data interaction delay time, P ML is the power imbalance detection value, P MW is the current unbalance detection value, P MC is the voltage imbalance detection value, P MS is the intelligent detection value, P MX is the error detection value;
[0047] The formula for the data interaction delay detection model comprehensively considers multiple factors, including power imbalance, current imbalance, voltage imbalance, intelligent detection, and error detection. By taking these factors into account, it can more comprehensively evaluate the data interaction delay duration, improving the accuracy of the model. Because the formula integrates multiple detection values, the flexibility of the formula enables it to adapt to various situations when different detection parameters are involved in different scenarios. The formula of the data interaction delay detection model that comprehensively considers multiple factors helps to improve the understanding and evaluation of data interaction delay duration and provides a useful tool for decision-making, optimization, and standardization. It can adapt to various situations, quantify problems, support decision-making, and help improve system performance.

[0049] The API interface is used for data interaction between modules.
[0050] The human-computer interaction module is divided into a client and a server, and is used to implement remote screen calls between the cloud and edge clusters in a vertical environment. The client connects to the server via JMS, obtains standard SVG screen files and displays them in the client browser, receives data packets in real time, and refreshes the screen. The server responds to client requests and provides standard SVG screen files and screen-related DL476 extended data packets via JMS. Remote screen calls are based on the SVG and DL476 standards and JMS services, where SVG serves as the standard for screen content definition and DL476 serves as the standard for data transmission protocol. The JMS service is responsible for communication and data exchange between the browsing and browsing ends.
[0051] Among them, the client functions include the client screen remote call browser and client gateway service. The screen remote call browser is mainly used to view the screen information from various edge clusters vertically and various other systems horizontally. The browser sends open screen, data refresh, and stop refresh requests to the gateway of each screen call server according to the operation. It also displays the screen file sent by the other end in the browser window and refreshes the relevant data in real time on the screen to ensure that its screen display result is basically consistent with the screen of the other end system. The client gateway service sends various browser requests to the server gateway machine through the JMS data service, receives various data returned by it, and forwards it to the corresponding browser end.
[0052] The server needs to convert the local screen into a standard SVG screen file and be able to upload the correct SVG screen file according to the open screen request sent by the client. After the screen file transmission is completed, it responds to the data refresh request and sends the corresponding data of the screen to the client in real time in the format of the extended DL476 protocol, and can also upload the changed data in the screen in real time.

[0067]
[0068] Where: W TW is the bus phase current deviation value, W XW It is the current balance detection value of the opposite end of the line;

The voltage unbalance detection model can adapt to various situations, quantify problems, support decision-making, and help improve power system performance.

It can quickly calculate the error detection value, thereby quickly identifying potential problems or abnormal situations, helping to detect and deal with data errors early, improve data quality and reliability, and help to quickly and effectively identify and quantify data errors, improve data quality, and support data analysis and decision-making processes.
[0082] The power imbalance detection value is obtained by establishing a power imbalance detection model based on the busbar active power balance detection value, busbar reactive power balance detection value, line end active power balance detection value, line end reactive power balance detection value, transformer active power balance detection value, and transformer reactive power balance detection value. For the busbar active power balance detection value, under normal circumstances, the accumulated value of the active power flowing into the busbar and the active power flowing out of the busbar tends to 0.

For the detection of unreasonable main transformer gear value, when the difference between the estimated gear and the measured gear of the transformer exceeds the specified range, the plant station will list this indicator. When the on-load tap changer gear exceeds the highest gear or is lower than the lowest gear, this indicator will be listed at the plant station; for the detection of the reactive error value of the capacitor, when the error between the calculated reactive value and the actual measured value of the capacitor is large, the plant station will list this indicator; for the detection of unreasonable telemetering value, when the telemetering value information shows that the switch or knife switch is closed or open, which is inconsistent with the telemetering value, it means that the telemetering value or telemetering value is incorrect, and the plant station will list this indicator; for the detection of the knife switch and busbar detection value, when two knife switches are connected to the busbar in parallel, the plant station will list this indicator.
[0088] The error detection value is obtained by establishing an error detection model based on multi-source data errors and missing forwarding source values. For the detection of multi-source data errors, the local RTU data of each measuring point of each plant station is compared with the ground-tuning forwarding data. When the telesignaling is inconsistent or the telemetry error is large, the plant station will list this indicator; for the detection of missing forwarding source values, when the measuring point data lacks a forwarding source, the plant station will list this item.

A data interaction system for supporting different container groups according to claim 2, characterized in that: Horizontal interaction requires that data interaction between cloud applications use the message bus MQ provided by the control cloud, build a message sending and receiving mechanism between business application functions, and realize data subscription interaction between cloud applications by customizing different topics. The data is pushed to the cloud data center, and the cloud data center customizes data services, which are then used to provide application data services to the outside world. Vertical interaction requires data interaction between cloud applications and edge clusters, which is realized by the application interaction services provided by the cloud system platform and the application interaction agents of each cloud.
