Description

Technical Field

[0001] The present invention relates to the technical field of power grid data processing and display, and more specifically, to a multi-topic power grid information switching and presenting system and method. Background Art

[0002] In today's rapidly developing power industry, the complexity of power grid information is increasing day by day. With the continuous advancement of smart grid technology and the continuous expansion of the power grid scale, various types of information such as real-time data, historical data, fault alarm information, and equipment status information are intertwined with each other, constructing a huge and complex information network. To store and display this information, a power grid information switching and presenting system has emerged. With the help of highly integrated and intelligent data processing technology, this system integrates and analyzes power grid information from different sources and in different formats, and constructs an intuitive and clear information display interface. Staff only need to perform simple operations to easily switch and view various types of power grid information, and then comprehensively understand and monitor the power grid status. This system not only greatly improves work efficiency, but also reduces the risk of human misjudgment, providing a strong guarantee for the safe and stable operation of the power grid.

[0003] The Chinese invention patent with the patent name "A panoramic visualization display system for power grid operation information" and the publication number CN104537573A has been publicly disclosed. This patent integrates power grid equipment resources, power grid operation information, and power grid management business information, and provides strong assistance for power grid operation decision-making through statistical analysis and data mining of this information; at the same time, these analysis results are visually displayed in the form of images, and other systems are supported to call these analysis results. This invention patent can help staff intuitively see the power grid operation status and fault points, but this patent fails to fully consider the continuous expansion of the current power grid scale and the significant increase in power consumption load. These factors lead to a sharp increase in the amount of information that the system needs to process, and a large amount of data cannot be analyzed and integrated in a timely manner, resulting in information presentation lag; under high-load information processing, data transmission is affected, and thus the response time of the system becomes longer, which cannot meet the needs of staff for quickly switching and viewing power grid information and making timely decisions.

[0061] 1. The present invention adopts a modular design, a distributed processing architecture, and an optimized data processing strategy, which together constitute an efficient, stable, and responsive data processing and display system. This system includes a data receiving module, a processing module, a display module, and a storage module. The modules cooperate efficiently with each other, thereby greatly improving the data processing ability, accelerating the information display speed, and ensuring the stable storage of data. The overall system performance is excellent and the operation is efficient. The modular design can also effectively prevent the malfunction of one module from having an adverse impact on other modules and facilitate the expansion and upgrade of the system.

[0062] 2. The present invention also adopts a distributed architecture for the processing module, aiming to improve the data processing and transmission capabilities. Specifically, a plurality of first execution units are provided in the first-level processing module.

For the data required by other interfaces, it will be stored in a temporary buffer after processing. When the user switches the display interface, the display module can directly retrieve the required data from the temporary buffer, thus greatly reducing the response time for switching interfaces. At the same time, the present invention also feeds back the signal of display interface switching to the processing module in real time, enabling the processing module to adjust the priority of data processing according to the current requirements, ensuring that the data of the current display interface can be preferentially processed and directly transferring the relevant data from the processing module to the display module.

[0074] Embodiment 1

[0075] Please refer to Figures 1 - 8 , the present invention provides a multi-topic power grid information switching and presentation system and method, including a data receiving module, a processing module, a display module, and a storage module; the data receiving module, the processing module, and the display module are connected in sequence; the storage module is respectively connected to the processing module and the display module.

[0076] The data receiving module is used to receive monitoring data and perform formatting processing, and then perform labeling processing on the formatted monitoring data according to the labeling rule to obtain labeled data; after the labeling is completed, the labeled data is transmitted to the processing module for the next step of processing; the monitoring data is the data of each node of the power grid, and the monitoring data includes but is not limited to current, voltage, power, frequency, phase angle, switch state, discharge amount, three-dimensional structure data, and image data.

[0077] It should be noted that with the continuous expansion of the power grid scale and the increasing number of monitoring nodes, the data format shows diversification. By formatting the monitoring data, it can ensure that the subsequent modules can effectively receive and process these data, improving the readability and accuracy of the data.

[0078] In this embodiment, the labeling rule of the data receiving module includes the steps:

[0079] Step S101: Receive the monitoring data and perform a first marking on the monitoring data according to the data source to obtain the first-labeled data;

[0080] Step S102: Perform a second marking on the first-labeled data according to the data type to obtain the labeled data.

[0081] It should be noted that the data types include, but are not limited to, current, voltage, power, frequency, phase angle, switch state, discharge amount, three-dimensional structure data, and image data.

[0082] It should be noted that the subsequent module can trace the source of the monitoring data according to the data source, which helps to track the flow and changes of the data during the data processing and analysis process; the subsequent module can select the appropriate data processing channel according to the data type, avoiding processing delays and errors caused by data confusion, thereby improving the overall data processing efficiency.

[0083] A processing module, which is used to process the labeled data classification according to the label information of the labeled data; detect the processed data to determine whether it is abnormal data;

[0084] The processing module includes a primary processing module, a secondary processing module, a tertiary processing module, a monitoring module, and a prediction module. The primary processing module, the secondary processing module, and the tertiary processing module are connected in sequence; the primary processing module, the secondary processing module, and the tertiary processing module are respectively connected to the monitoring module; the monitoring module is connected to the display module; the primary processing module is connected to the data receiving module; the secondary processing module is respectively connected to the storage module, the display module, and the prediction module; the tertiary processing module is respectively connected to the display module and the prediction module; the prediction module is connected to the storage module;

[0085] The primary processing module includes multiple first execution units. The multiple first execution units receive the labeled data transmitted by the data receiving module in parallel and classify it; the first execution unit transmits the classified labeled data to the secondary processing module through a message queue;

[0086] The secondary processing module includes multiple second execution units. The second execution unit receives the labeled data and preprocesses the labeled data to obtain processed data; the secondary processing module transmits the processed data to the storage module and the tertiary processing module respectively;

[0087] It should be noted that the first execution unit classifies the labeled data according to the data type in the label information, and transmits the data to the message queue according to the classification result; each channel in the message queue corresponds to a second execution unit, and the second execution unit can directly extract and process the received data from the corresponding channel;

[0088] It should be noted that the preprocessing is divided into numerical preprocessing and image preprocessing. The data preprocessing methods include, but are not limited to, identifying and processing missing values in the data, and standardizing the data; the image preprocessing methods include, but are not limited to, image grayscale conversion, image grayscale conversion, image grayscale conversion, image grayscale conversion, image grayscale conversion;

[0089] It should be noted that the first execution unit classifies the labeled data according to the data type, so that the second execution unit can perform targeted data preprocessing on the labeled data according to the data type. Such a design can effectively prevent problems such as data confusion, low efficiency, model performance degradation, and resource waste.

[0090] The prediction module retrieves historical data from the storage module and makes predictions based on the historical data and the data transmitted in real time by the secondary processing module to obtain prediction data; the prediction module transmits the prediction data to the tertiary processing module;

[0091] The tertiary processing module performs anomaly judgment on the processed data and the prediction data, and outputs a judgment signal to the display module;

[0092] The monitoring module monitors the working conditions of the primary processing module, the secondary processing module, and the tertiary processing module in real time, dynamically allocates the number of the first execution unit and the second execution unit to ensure load balancing of the primary processing module and the secondary processing module, and adjusts the priority of the data in the message queue.

[0093] Furthermore, the monitoring module dynamically allocates the number of the first execution unit and the second execution unit through the formula:

[0094]

[0095] where L represents the workload of the first execution unit in the working state; α represents the rate at which data arrives at the first execution unit; μ i represents the rate at which the i-th first execution unit processes data;

[0096] Through this formula, the workload of the first execution unit or the second execution unit in the current working state can be obtained; the workload of the first execution unit or the second execution unit in the working state is compared with a preset threshold, and the monitoring module adjusts the number of the first execution unit or the second execution unit according to the comparison result.

[0097] Specifically, taking the first execution unit as an example, let the preset upper threshold be L max , and the preset lower threshold be L min ,

[0098] When L≥L max , it means that the workload of the current first execution unit is relatively large, and a new first execution unit needs to be started to share the workload;

[0099] When L max >L≥L min It means that the workload of the current first execution unit is at an appropriate stage, and there is no need to increase or decrease the number of first execution units;

[0100] When L<Lmin When it is, it means that the workload of the current first execution unit is relatively small, and some of the first execution units can be appropriately shut down to avoid resource waste.

[0101] It should be noted that in this embodiment, constraint conditions are set during the data transmission process between the first execution unit and the second execution unit. On the one hand, it avoids the situation where the excessive number of first execution units leads to a sharp increase in the amount of data processed by the second execution unit, and further causes the system to crash due to overload. On the other hand, it also prevents the situation where the number of first execution units is too small, resulting in some second execution units being idle and causing resource waste. Such a design ensures the efficiency, accuracy of system data processing, and the reasonable utilization of network computing resources, and avoids excessive consumption or shortage of resources.

[0102] Specifically, let the network transmission rate between the first execution unit and the second execution unit be V, the amount of data that the second execution unit can currently process be Y, and the transmission time be T.

[0103] When Y>VT, it means that the amount of data transmitted by the first execution unit will not impose a burden on the second execution unit.

[0104] Specifically, the working process of the processing module in this embodiment includes the following steps:

[0105] Step S201: Multiple first execution units receive label data in parallel and classify the label data according to the data type; after completion, put the label data into the message queue; the data type includes but is not limited to current, voltage, power, frequency, phase angle, switch state, discharge amount, three-dimensional structure data, image data.

[0126] The alarm module starts the alarm state according to the judgment signal output by the tertiary processing module, divides the emergency level, and locates the grid fault node. The alarm module outputs the grid fault node information through the output module.

[0127] The output module is used to output data to an external display for displaying grid information.

[0129] Step S1: Receive monitoring data according to a preset reception frequency and label it to obtain labeled data;

[0130] Step S2: The first execution unit classifies the labeled data according to the labeling information;

[0131] Step S3: The second execution unit preprocesses the labeled data according to the classification result to obtain processed data; temporarily store or compress and store the processed data;

[0132] Step S4: Perform anomaly judgment on the processed data. If the processed data is judged as abnormal data, execute Step S5; if the processed data is judged as normal data, execute Step S6;

[0133] Step S5: Output a judgment signal representing abnormal data and activate the alarm reminder function; after completion, execute Step S6;

[0139] The present invention adopts a modular design. The feature of such design is that it can effectively prevent the malfunction of one module from having an adverse impact on other modules, and is convenient for the system to be extended and upgraded.

[0140] The present invention also adopts a distributed architecture for the processing module, aiming to improve data processing and transmission capabilities. Specifically, multiple first execution units are provided in the primary processing module. Such a design enables that when one of the first execution units fails, a new first execution unit can be quickly added to replace it, thus ensuring the continuity and stability of data processing tasks. Similarly, the secondary processing module also adopts the same design concept.

[0141] In addition, the present invention optimizes the data processing strategy. First, the data required for the current display interface is preferentially processed and directly transmitted from the processing module to the display module to meet the immediate needs of users. For the data required for other interfaces, it will be stored in a temporary buffer after processing. When the user switches the display interface, the display module can directly retrieve the required data from the temporary buffer, thus greatly reducing the response time for switching interfaces. At the same time, the present invention also feeds back the signal of display interface switching to the processing module in real time, enabling the processing module to adjust the priority of data processing according to the current requirements, ensuring that the data of the current display interface can be preferentially processed and directly transmitting the relevant data from the processing module to the display module.

[0142] The present invention also provides a computer-readable storage medium, in which a program is stored. When a computer executes the program, it executes the above-mentioned method for switching and presenting multi-topic power grid information.

Those skilled in the art can fully understand how to implement the technical solutions of the present invention based on the above description.
