TECHNICAL FIELD

[0001] The present application relates to the technical field of power supply systems, in particular to an industrial internet monitoring system based on networked SVG. BACKGROUND

[0002] In the current power grid operation management, there are multiple pain points in data processing, topology visualization, state control and resource allocation, resulting in low monitoring feedback efficiency. On the one hand, the connection between power grid data collection, transmission and calculation is not smooth, which is prone to data processing faults and difficult to provide continuous and effective data support for monitoring. On the other hand, the distribution topology relies on manual drawing or lagging update, and the visualization presentation cannot match the actual structure of the power grid in real time. At the same time, the state monitoring and networked SVG device control lack linkage, abnormal conditions are difficult to respond in time, and the calculation resource allocation is unreasonable, resulting in resource waste or insufficient computing power. Under this background, it is urgent to build an industrial internet monitoring system based on networked SVG to solve the existing difficulties and improve the efficiency of power grid monitoring feedback and management level.

[0003] Chinese patent with publication number CN104375488A discloses a high-voltage SVG remote monitoring system, which includes a local area network, a router, a monitoring computer, a public digital mobile communication system, a high-voltage static reactive power generation device and a wireless communication device. Multiple monitoring computers form a local area network through a router and a network cable. The router is connected with the public digital mobile communication system through a network cable, the public digital mobile communication system is wirelessly connected with the wireless communication device, and the high-voltage static reactive power generation device and the wireless communication device are connected through an RS485 bus to form a field information acquisition unit. However, this scheme still has the problems of power grid data processing fault, topology visualization lag, state monitoring and device control disconnection, and unreasonable calculation resource allocation, resulting in low efficiency of networked SVG monitoring data feedback. SUMMARY

[0004] Therefore, the present application provides an industrial internet monitoring system based on networked SVG to overcome the problems of power grid data processing fault, topology visualization lag, state monitoring and device control disconnection, and unreasonable calculation resource allocation in the prior art, resulting in low efficiency of networked SVG monitoring data feedback.

[0005] To achieve the above-mentioned purpose, the present application provides an industrial internet monitoring system based on networked SVG, which comprises: a data acquisition module for acquiring power grid data; a data transmission module for transmitting power grid data through an industrial internet; a data calculation module for judging the data calculation volume according to the power grid data, selecting a calculation method according to the judgment result, calculating the power grid data according to the calculation method, and obtaining a calculation result. a topology modeling module configured to generate a power distribution topology diagram according to the calculation result and push the power distribution topology diagram to a network construction SVG control terminal; a topology monitoring module configured to monitor a power grid state according to the calculation result and update the power distribution topology diagram according to the monitoring result; a topology control module configured to perform topology control on the network construction SVG device according to the monitoring result.

[0006] Further, the data transmission module receives the power grid data collected by the data collection module and transmits the power grid data to the data calculation module through a wide area network.

[0007] Further, the data calculation module constructs a calculation volume estimation model by a calculation volume estimation model construction method to obtain the calculation volume estimation model, inputs the power grid data into the calculation volume estimation model, and obtains a calculation volume output by the calculation volume estimation model. When the calculation volume judgment result is the light calculation attribute, edge calculation is selected as the calculation method, the power grid data is downloaded to an edge server close to a power grid data collection point, the edge server is used to calculate the contaminated data, and a calculation result is obtained. When the calculation volume judgment result is the heavy calculation attribute, cloud calculation is selected as the calculation method, the power grid data is uploaded to a cloud data center, the cloud data center is used to calculate the power grid data, and a calculation result is obtained.

[0008] Further, the calculation volume estimation model construction method comprises: The calculation volume estimation data set in the power grid data is divided into a 70% estimation training set, a 15% estimation verification set, and a 15% estimation test set. The estimation training set is input into a decision tree model to train the decision tree model. The estimation verification set is input into the trained decision tree to perform hyperparameter iterative optimization on the trained decision tree. The estimation test set is input into the iterative optimization decision tree to perform conflict analysis testing on the iterative optimization decision tree model. An estimation test result is obtained. The total number of estimation test samples is b0, the number of correctly estimated test samples is b, the estimation test accuracy is B, B = b / b0. The estimation test accuracy B is compared with a preset estimation test accuracy B0. According to the comparison result, the training of the iterative optimization decision tree model is judged, and the judgment result is output. Wherein: When B≥B0, the data calculation module determines that the training of the iteratively optimized decision tree model has reached the target, outputs the iteratively optimized decision tree model as the computational volume estimation model, and provides the computational volume estimation model to the layout optimization module. When B < B0, the data calculation module determines that the training of the iteratively optimized decision tree model is not up to standard, updates the computational volume estimation dataset to obtain the updated computational volume estimation dataset, and trains, iteratively optimizes hyperparameters, and analyzes and tests the decision tree model based on the updated computational volume estimation dataset until the training of the decision tree model is up to standard.

[0009] Furthermore, the topology modeling module constructs a distribution topology generation model using a distribution topology generation model construction method, which includes: Step A1: Select a convolutional neural network model as the basic framework for the distribution topology generation model, and divide 70% of the distribution topology generation sample dataset in the power grid data into a topology generation training set, 15% into a topology generation validation set, and 15% into a topology generation test set. Step A2: Train the convolutional neural network model according to the topology generation training set, update the weights of the convolutional neural network model through the backpropagation algorithm, and after each epoch, validate the convolutional neural network model using the topology generation validation set to obtain the topology generation validation loss value and the topology generation validation accuracy. Step A3: When the topology generation verification loss value and the topology generation verification accuracy meet the preset verification conditions, the convolutional neural network model is tested according to the topology generation test set to obtain the topology generation test accuracy. When the topology generation test accuracy reaches the preset accuracy, the convolutional neural network model is output as the distribution topology generation model.

[0010] Furthermore, the topology modeling module extracts the power grid connection relationship information from the calculation results, constructs a real-time connection state logic diagram of the power grid using graph theory and the power grid connection relationship information, inputs the connection state logic diagram into the distribution topology generation model, obtains the distribution network topology diagram output by the distribution topology generation model, and pushes the distribution network topology diagram to the network SVG control terminal.

[0011] Furthermore, the topology monitoring module constructs a threshold database based on preset safety values ​​in the power grid data. The threshold database includes calculation items, thresholds corresponding to the calculation items, and comparison results of the calculation items.

[0012] Furthermore, the topology monitoring module compares the item values ​​of the calculated items in the calculation results with the corresponding thresholds in the threshold database to obtain the comparison results of the calculated items. These comparison results are then output as monitoring results, and the distribution network topology diagram is updated based on the monitoring results. When the value of the calculated item in the calculation result is less than or equal to the threshold corresponding to the calculated item in the threshold database, the topology monitoring module determines that the comparison result of the calculated item is normal and does not update the power distribution network diagram. When the value of a calculated item in the calculation result is greater than the threshold corresponding to the calculated item in the threshold database, the topology monitoring module determines that the comparison result of the calculated item is abnormal, updates the power distribution network topology diagram, and marks the calculated items with abnormal monitoring results in the power distribution network diagram.

[0013] Furthermore, the topology control module constructs the topology scheme model using the topology scheme model construction method to obtain the topology scheme model.

[0014] Furthermore, the topology control module inputs the monitoring results into the topology scheme model, obtains the topology control scheme output by the topology scheme model, and performs topology control on the network SVG devices according to the topology control scheme.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: the system accurately collects power grid data through a data acquisition module, providing real and complete basic data support for subsequent data transmission and calculation. The system also relies on an industrial internet gateway through a data transmission module to stably transmit data, ensuring efficient and secure transmission of power grid data and preventing data loss. Furthermore, the system selects calculation methods as needed through a data calculation module to efficiently process power grid data, providing accurate calculation results for topology modeling and monitoring. The system also quickly generates distribution network topology diagrams and pushes them to terminals through a topology modeling module, helping staff intuitively grasp the power grid topology structure. Additionally, the system monitors the power grid status in real time through a topology monitoring module, updating the topology diagram promptly, allowing staff to accurately grasp dynamic changes in the power grid. Finally, the system controls the network SVG equipment based on monitoring results through a topology control module, ensuring the power grid operates in optimal condition and improving power supply stability.
