Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.
[0048] Example 1
[0049] Reference Figure 1-Figure 4 , as an embodiment of the present invention, provides a power grid equipment topology data processing system, including:
[0050] Figure 1 A system structure diagram of a power grid equipment topology data processing system and method is shown, including:
[0051] Data monitoring and collection module 100, data checking module 200, data time marking module 300, aging calculation module 400, data processing module 500, data verification module 600, topology model 700, problem location module 800, problem display module 900;
[0052] The data checking module 200 is used to detect the data collected by the data monitoring and collecting module 100;
[0053] The data time marking module 300 is used to mark the detection time of the correct data detected in the data monitoring and collection module 100;
[0054] The data processing module 500 is used to process the data marked in the data time marking module 300, verify the processed data using the data verification module 600, and transmit it to the topology model 700;
[0055] The topology model 700 is used to verify the processed data and the data of the aging calculation module 400 according to the data verification module 600, obtain the problem of the power grid, locate the problem of the power grid using the problem location module 800, and display the problem through the problem display module 900.
[0056] Specifically, Figure 1 As shown, the output end of the data monitoring and acquisition module 100 is connected to the data time marking module 300, and the data time marking module 300 performs time marking on the correct data detected by the data monitoring and acquisition module 100, marking the detection time of this group of correct data.
[0057] The aging calculation module 400 is connected to the output end of the data time stamp module 300. The aging calculation module 400 infers the aging degree of the equipment in the power grid according to the data changes in each period of time.
[0058] The output end of the data time marking module 300 is connected to the data processing module 500. The data processing module 500 can process the data marked by the data time marking module 300 to make the format and content of the data more in line with the calculation requirements.
[0059] like Figure 1 As shown, the output end of the data processing module 500 is connected to the data verification module 600, which can ensure that the data processed by the data processing module 500 does not lose important data, and then transmit the correct data verified by the data verification module 600 to the topology model 700 for operation.
[0060] The topology model 700 is connected to the output end of the data verification module 600 . The topology model 700 calculates the problems existing in the power grid according to the data of the data verification module 600 and the data of the aging calculation module 400 .
[0061] The output end of the topology model 700 is connected to a problem location module 800, which can locate the problem according to the problem, thereby calculating the location and cause of the problem, and then display the problem on the problem display module 900, so that the staff can find the problem and deal with it. The problem location module 800 adopts a fault diagnosis algorithm to quickly detect and locate faulty equipment or areas in the power grid by analyzing the topological structure and related data.
[0062] It should be noted that this system ensures that the data detected each time is complete, to avoid missing data and thus calculation errors due to damage to the detection components;
[0063] The device compares all the data and calculates the deviation between the two data inputs and outputs. If the data deviation is large, the device will detect the data again to form three groups of data, and then select one of the two groups of similar data to determine that the selected data is the correct data, so as to avoid a mistake that causes the data used by the entire system to be wrong, affecting the calculation results of the system;
[0064] By inferring the aging degree of the power grid equipment during this period, and calculating the data deviation caused by the aging of the power grid equipment during this period, the data deviation caused by the aging of the power grid equipment can be removed during the operation of the system, avoiding the impact of aging problems on the system's decision-making.
[0065] In the embodiments of the present application, Figure 2As shown, the data checking module 200 includes a data item checking module 201, an alarm module 202, a missing item marking module 203, a data deviation detection module 205, a first rechecking module 204 and a second rechecking module 206;
[0066] The data item checking module 201 detects all detection items of the data collected by the data monitoring and collecting module 100, and uses the alarm module 202 to alarm for the data that cannot be detected;
[0067] The missing item marking module 203 marks the missing items detected by the data item checking module 201, and uses the first rechecking module 204 to feed back the marked missing items to the data monitoring and collecting module 100 to recheck the missing items.
[0068] The data deviation detection module 205 checks the detected data with the data of the last detection, uses the second re-check module 206 to determine that the data deviation on both sides is greater than the first threshold, controls the data monitoring and acquisition module 100 to perform a third data detection, and selects one of the two most recent sets of data for use.
[0069] Specifically, the data checking module 200 is connected to the data monitoring and acquisition module 100 in input and output. The data checking module 200 includes a data item checking module 201, an alarm module 202, a missing item marking module 203 and a first rechecking module 204. The data item checking module 201 is connected to the output end of the data monitoring and acquisition module 100. The data item checking module 201 checks the detection data item in the data monitoring and acquisition module 100 to ensure that the data monitoring and acquisition module 100 monitors all detection items.
[0070] The alarm module 202 is connected to the output end of the data item checking module 201. When the alarm module 202 determines that a certain data item cannot be detected, it performs an alarm process, so that the staff can repair the problem in time.
[0071] The missing item marking module 203 is connected to the output end of the data item checking module 201, and the alarm module 202 and the missing item marking module 203 are connected in parallel. The missing item marking module 203 can mark the missing items detected by the data item checking module 201, so that the system can clearly know which part of the data is missing;
[0072] The first recheck module 204 is connected to the output end of the missing item marking module 203. The first recheck module 204 can feed back the missing items marked by the missing item marking module 203 to the data monitoring and collection module 100, so that the data monitoring and collection module 100 rechecks the missing items.
[0073] When the data item verification module 201 finds that there are missing items in the data detected by the data monitoring and acquisition module 100, it will mark the missing data type through the missing item marking module 203, and then control the data monitoring and acquisition module 100 to recheck the data through the first re-check module 204, so as to supplement the missing data. The supplemented data will also be tested by the data item verification module 201. If the data item verification module 201 still detects that there are missing items, the alarm module 202 will be used to alarm, so that the staff will go to the inspection end to determine whether the detector is damaged, thereby ensuring that the data detected by the data monitoring and acquisition module 100 each time is complete data, avoiding damage to the detection element, resulting in missing data in the system and thus calculation errors.
[0074] Specifically, the data checking module 200 further includes a data deviation detection module 205 and a second rechecking module 206. The output end of the data item checking module 201 is connected to the data deviation detection module 205, and the data deviation detection module 205 is connected in parallel with the data item checking module 201, the alarm module 202 and the first rechecking module 204. The data deviation detection module 205 can check the data detected later with the data detected last time, thereby forming multiple detections of the data to ensure the accuracy of the detected data;
[0075] The second re-check module 206 is connected to the output end of the data deviation detection module 205. When the data deviation detection module 205 determines that the data deviation on both sides is greater than the first threshold value of 60, the second re-check module 206 can control the data monitoring and acquisition module 100 to perform a third data detection, thereby performing three data comparisons and selecting one of the two most recent groups of data for use.
[0076] The data item verification module 201 transmits all the verified data and the data re-detected by the data monitoring and acquisition module 100 to the data deviation detection module 205 for comparison, so as to calculate the deviation of the two data in and out. If the data deviation is greater than 60, the second re-check module 206 will perform data detection again to form three groups of data, so as to select one of the two most recent groups of data, so as to determine that the data selected for use is the correct data, so as to avoid a mistake that causes the data used by the entire system to be wrong, affecting the calculation results of the system.
[0077] In the embodiments of the present application, Figure 3 As shown, the aging calculation module 400 includes a historical data storage module 401, a time sorting module 402, an equipment aging inference module 403, a geographic information collection module 404, and an aging deviation data module 405;
[0078] The historical data storage module 401 stores the data marked in the data time marking module 300 to obtain a historical database;
[0079] The time sorting module 402 retrieves all the data stored in the historical data storage module 401 according to the first time threshold, sorts them according to time, and arranges them in chronological order;
[0080] The equipment aging inference module 403 calculates the aging degree of the power grid equipment based on the data from the time sorting module 402 and the geographic information collection module 404 .
[0081] The geographic information collection module 404 collects the location of the power grid equipment and detects the geographical environment at the location;
[0082] The aging deviation data module 405 calculates the data impact of aging on the power grid equipment based on the result inferred by the equipment aging inference module 403, and obtains the abnormal data caused by the aging of the equipment.
[0083] Specifically, the aging calculation module 400 includes a historical data storage module 401, a time sorting module 402 and an equipment aging inference module 403. The historical data storage module 401 can store the data marked by the data time marking module 300, thereby forming a historical database;
[0084] The time sorting module 402 is connected to the output end of the historical data storage module 401. The time sorting module 402 takes out all the data stored in the historical data storage module 401 during the period of 60 seconds according to the first threshold value of 60 seconds, and then sorts them according to time, sorts all the detection data at the same time together, and arranges them in chronological order;
[0085] The equipment aging inference module 403 is located at the output end of the time sorting module 402 . The equipment aging inference module 403 can calculate the aging degree of the power grid equipment according to the data of the time sorting module 402 and the geographic information collection module 404 .
[0086] like Figure 3 As shown, the aging calculation module 400 also includes a geographic information collection module 404 and an aging deviation data module 405. The input end of the equipment aging inference module 403 is connected to the geographic information collection module 404, and the geographic information collection module 404 is connected in parallel with the time sorting module 402. The geographic information collection module 404 can collect the location of the power grid equipment and detect the geographical environment at the location;
[0087] The aging deviation data module 405 is connected to the output end of the equipment aging inference module 403. The aging deviation data module 405 can calculate the data impact of aging on the power grid equipment based on the results inferred by the equipment aging inference module 403, thereby eliminating data anomalies caused by equipment aging.
[0088] It should be noted that, through the collaborative work of the data item verification module 201, the alarm module 202, the missing item marking module 203 and the first recheck module 204, the system can ensure the integrity of the collected data, timely discover and supplement the missing data, thereby avoiding calculation errors caused by missing data. The introduction of the data deviation detection module 205 and the second recheck module 206 enables the system to check the continuously detected data to ensure the consistency and reliability of the data. When the data deviation exceeds the preset first threshold (for example, 60), the system will trigger re-detection and select one of the two closest groups of data as the correct data, thereby improving the system's anti-interference ability. Through multiple data detection and recheck mechanisms, the system can quickly identify potential faults and promptly notify the staff through the alarm module 202 to carry out maintenance, thereby reducing the impact of faults on power grid operation.
[0089] The aging calculation module 400 can accurately infer the aging degree of power grid equipment based on historical data and geographic information, and eliminate data anomalies caused by equipment aging through the aging deviation data module 405, thereby extending the service life of the equipment and reducing maintenance costs. Through precise equipment aging management and fault detection, the system can reduce the risk of unexpected power outages and equipment failures, and improve the operating efficiency and safety of the power grid.
[0090] like Figure 4 As shown, this embodiment also provides a method for processing power grid equipment topology data, including:
[0091] S100: Acquire power grid data, detect the power grid data to obtain first detection data and second detection data, and pre-process the first detection data to obtain third detection data;
[0092] S200: Process the third detection data to obtain processed detection data, and verify the processed detection data with the second detection data to obtain correct data;
[0093] S300: Acquire historical data, calculate the aging degree of power grid equipment and the impact of aging on the data of power grid equipment according to the historical data, and obtain equipment aging abnormal data and aging deviation data;
[0094] S400: Analyze the topology of the power grid using the correct data, the abnormal aging data of the equipment, and the aging deviation data using a fault diagnosis algorithm, and identify and locate the power grid problem.
[0095] Specifically, the fault diagnosis algorithm includes a distance protection-based method or an artificial intelligence-based method;
[0096] In the distance protection-based method, the fault distance is expressed as Z = V / I, where V is the fault phase voltage and I is the fault phase current;
[0097] Based on the artificial intelligence method, the training of the RBFN model includes inputting the extracted features as input vectors into the RBFN model and calculating the output of each hidden layer neuron as:
[0098]
[0099] Where x is the input vector, c is the center of the i-th hidden neuron, σ is the variance of the i-th hidden neuron, and ‖xc‖ is the Euclidean distance between x and c;
[0100] The output layer is calculated based on the hidden layer output and weights, and the result is expressed as:
[0101]
[0102] Among them, yk(x) is the output of the kth output neuron, ω ik is the weight between the i-th hidden layer neuron and the k-th output neuron, and M is the number of hidden layer neurons;
[0103] Use the least squares method or other optimization algorithms to adjust the weights so that the network output is close to the expected fault diagnosis result. The weights are expressed by the minimum multiplication method as:
[0104] W=Φ T Y
[0105] Among them, Φ is the matrix of hidden layer output, and Y is the expected output vector.
[0106] It should be noted that by acquiring the first detection data and the second detection data, and performing preprocessing and data processing, the accuracy and completeness of the data are ensured. By using correct data, equipment aging abnormal data and aging deviation data, combined with a fault diagnosis algorithm, the topology of the power grid can be accurately analyzed, power grid problems can be identified and located, and the distance protection-based method can quickly determine the fault location by calculating the fault distance, while the artificial intelligence-based method can quickly and accurately perform fault diagnosis by training the RBFN model. In the artificial intelligence-based method, the output of the hidden layer neurons and the results of the output layer are calculated, and the weights are adjusted using the least squares method or other optimization algorithms, so that the output of the network is close to the expected fault diagnosis result, thereby improving the performance and accuracy of the neural network.
