DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0031] To facilitate understanding of this embodiment, the embodiments of the present application are described in detail below.

[0032] The present application embodiment provides a method for locating an abnormality of a grounding clamp, such as Figure 1 As shown, Figure 1 A schematic flow chart of a method for locating an abnormality of a grounding clamp provided in an embodiment of the present application. The method comprises the following steps: S101: The processor obtains initial state data of each grounding clamp.

[0033] The initial state data of each grounding clamp includes: initial temperature data and initial humidity data.

[0034] Specifically, each of the above grounding wire clamps is installed with a temperature sensor and a humidity sensor. When starting detection, the processor obtains initial temperature data of each grounding wire clamp through the temperature sensor, and obtains initial humidity data of each grounding wire clamp through the humidity sensor.

[0035] S102: The processor adjusts the initial collection time interval according to the initial state data of each grounding clamp to obtain the collection time interval.

[0036] Specifically, the processor is provided with an adaptive strategy, which can adaptively adjust the time interval for collecting the status data of each grounding clamp, and obtain the status data of each grounding clamp in real time.

[0037] With such a setting, the processor can accurately determine the frequency of collecting status data. If the grounding clamp is in a good environment, the collection time interval can be appropriately extended, that is, the collection frequency can be reduced, thereby reducing the acquisition of unnecessary status data; if the grounding clamp is in a bad environment, the collection time interval can be appropriately shortened, that is, the collection frequency can be increased, thereby obtaining more comprehensive status data. In addition, with such a setting, the processor can reasonably allocate computing resources and memory space to avoid frequent data collection and storage operations from having a negative impact on system performance.

[0038] S103: The processor obtains status data of each grounding clamp according to a collection time interval.

[0039] The status data of each grounding clamp includes temperature data and humidity data.

[0040] Specifically, changes in the temperature and humidity data may cause the material properties of the grounding clamp to deteriorate, thereby affecting its electrical performance and safety. For example, excessively high temperatures may cause the material of the grounding clamp to expand or deform, while excessively high humidity may cause the grounding clamp to corrode or deteriorate its insulation properties.

[0041] It can be seen from the above that by acquiring the temperature data and humidity data of each grounding clamp through the above processor, possible faults can be effectively predicted and prevented.

[0042] S104, the processor analyzes the status data of each grounding clamp and determines whether the grounding clamp at the monitoring data point at the current moment is in an abnormal state. If so, execute step S105, if not, execute step S103.

[0043] Specifically, the processor removes the state data of each grounding clamp that is physically impossible or abnormal due to equipment failure from the acquired state data to ensure the consistency of the state data. The processor is provided with an abnormality monitoring strategy, which can analyze the state data of each grounding clamp and determine whether the grounding clamp at the monitoring data point at the current moment is abnormal.

[0044] With this arrangement, the processor can monitor the status of each grounding wire clamp in real time and analyze the status data of each grounding wire clamp to determine whether the grounding wire clamp at the monitoring data point at the current moment is in an abnormal state. This does not require a large amount of manpower to conduct regular inspections of the grounding wire clamps, thereby improving the efficiency of grounding wire clamp fault monitoring and the accuracy of grounding wire clamp fault detection, saving manpower and time.

[0045] S105: The processor performs cluster analysis on the monitoring data points where the grounding wire clamps with abnormal status at the current moment are located, and generates a plurality of abnormal area clusters.

[0046] Specifically, the processor pre-sets a data group number threshold M. The above cluster analysis process is: the processor calculates the distance between every two monitoring data points where the grounding wire clamps are located at the current moment, merges the monitoring data points where the two grounding wire clamps at the current moment with the smallest distance, and generates multiple first data groups. The processor calculates the distance between every two first data groups, merges the two first data groups with the smallest distance, and generates multiple second data groups. The processor calculates the distance between every two second data groups, merges the two second data groups with the smallest distance, and generates multiple third data groups, until multiple Nth data groups are generated. If the number of Nth data groups is ≤M, the processor stops the cluster analysis, and at this time each Nth data group is an abnormal area cluster.

[0047] With such a configuration, the processor can accurately locate the grounding wire clamp with abnormal status in each abnormal area cluster. When maintaining the grounding wire clamp with abnormal status, it can be directly located in the abnormal area cluster where the grounding wire clamp with abnormal status is located for maintenance, thus avoiding the situation where the grounding wire clamp with abnormal status is scattered in various areas and difficult to maintain uniformly.

[0048] The embodiment of the present application provides a method for locating abnormal grounding wire clamps, in which a processor acquires the status data of each grounding wire clamp according to the collection time interval, analyzes the status data of each grounding wire clamp, and obtains a third analysis result. If the third analysis result is that the status of the grounding wire clamp at the monitoring data point at the current moment is abnormal, the processor performs cluster analysis on the monitoring data point where the grounding wire clamp is located at the current moment, and generates multiple abnormal area clusters. In this method, the processor performs cluster analysis on the monitoring data point where the grounding wire clamp is located at the current moment, and realizes the accurate positioning of grounding wire clamps with abnormal status scattered in various areas.

[0049] In the prior art, the status of grounding wire clamps dispersed in various areas is monitored solely by manpower, and the position of grounding wire clamps with abnormal status is determined based on the status data detected manually, and the grounding wire clamps with abnormal status are maintained manually. Compared with the prior art, this method does not require manual determination of the position of grounding wire clamps with abnormal status, and the positioning of grounding wire clamps with abnormal status is more accurate, which saves time for maintaining grounding wire clamps with abnormal status, improves the efficiency of maintaining grounding wire clamps with abnormal status, and thus significantly improves the safety, reliability and efficiency of operation and maintenance of the distribution network.

[0050] In addition, the method can automatically obtain the status data of each grounding wire clamp to monitor the status of each grounding wire clamp in real time, and can adaptively adjust the time interval of the status data obtained by the processor according to the actual environment in which the grounding wire clamp is located, thereby improving the accuracy and flexibility of data collection.

[0051] The following is an introduction to the method in which the processor adjusts the initial collection time interval according to the initial state data of each grounding wire clamp to obtain the collection time interval. The above-mentioned initial collection time interval includes the initial temperature collection time interval and the initial humidity collection time interval; the processor calculates the first judgment result according to the initial temperature data of each grounding wire clamp; the calculation formula of the first judgment result is:

[0052] in, is the first judgment result, is the threshold value of the number of temperature monitoring data points, is the initial temperature data of the i-th grounding clamp, is the temperature safety threshold, is the acquisition time threshold, is the number of initial temperature data; The processor calculates the second judgment result according to the initial humidity data of each grounding wire clamp; the calculation formula of the second judgment result is:

[0053] in, is the second judgment result, is the threshold of the number of humidity monitoring data points, is the initial humidity data of the jth grounding clamp, is the humidity safety threshold, is the acquisition time threshold, is the number of initial humidity data; If the first judgment result is 1 or the second judgment result is 1, the processor calculates the collection time interval; the calculation formula of the collection time interval is:

[0054] in, is the sampling time interval, is the initial temperature collection time interval, is the initial humidity collection time interval, is the rounding function, is the number of times the initial temperature data is greater than the temperature safety threshold, is the number of times the initial humidity data is greater than the humidity safety threshold, is the initial temperature data of the i-th grounding clamp, is the temperature safety threshold, is the initial humidity data of the jth grounding clamp, is the humidity safety threshold.

[0055] Specifically, if within the collection time threshold, the number of humidity monitoring data points where the grounding wire clamp whose initial humidity data is greater than the humidity safety threshold is greater than the humidity monitoring data point number threshold, it means that the grounding wire clamp is in a harsh environment. At this time, the initial humidity collection time interval can be shortened; if within the collection time threshold, the number of humidity monitoring data points where the grounding wire clamp whose initial humidity data is greater than the humidity safety threshold is less than the humidity monitoring data point number threshold, it means that the grounding wire clamp is in a good environment. At this time, the initial humidity collection time interval can be extended.

[0056] If within the collection time threshold, the number of temperature monitoring data points where the grounding wire clamp whose initial temperature data is greater than the temperature safety threshold is greater than the temperature monitoring data point number threshold, it means that the grounding wire clamp is in a harsh environment. In this case, the initial temperature collection time interval can be shortened; if within the collection time threshold, the number of temperature monitoring data points where the grounding wire clamp whose initial temperature data is greater than the temperature safety threshold is less than the temperature monitoring data point number threshold, it means that the grounding wire clamp is in a harsh environment. In this case, the initial temperature collection time interval can be extended.

[0057] In this manner, if the processor determines that the grounding clamp is in a good environment, the initial temperature collection time interval or the initial humidity collection time interval may be appropriately extended to reduce the acquisition of unnecessary temperature data or humidity data; if the grounding clamp is in a harsh environment, the initial temperature collection time interval or the initial humidity collection time interval may be appropriately shortened to obtain more comprehensive temperature data or humidity data.

[0058] The following is an introduction to the way in which the processor analyzes the status data of each grounding wire clamp to obtain the third analysis result. The processor calculates the exponentially weighted moving average of the status data of the grounding wire clamp at the current moment based on the status data of each grounding wire clamp; the calculation formula for the exponentially weighted moving average of the status data of the grounding wire clamp at the current moment is:

[0059] in, is the exponentially weighted moving average of the grounding clamp status data at the current moment, is the smoothing coefficient, is the observed value of the state data of the grounding clamp at the current moment, It is the exponentially weighted moving average of the state data of the grounding clamp at the previous moment; The processor calculates the third analysis result based on the exponentially weighted moving average value of the state data of the grounding wire clamp at the current moment; the calculation formula of the third analysis result is:

[0060] in, For the third analysis result, is the exponentially weighted moving average of the grounding clamp status data at the current moment, is the upper threshold, is the lower threshold.

[0061] The upper threshold is calculated as follows:

[0062] in, is the upper threshold, is the average value of the status data of the grounding clamp, is the standard deviation of the status data of the grounding clamp; The calculation formula for the lower threshold is:

[0063] in, is the lower threshold, is the average value of the status data of the grounding clamp, is the standard deviation of the status data of the grounding clamp.

[0064] Specifically, the processor uses a time series to analyze the status data of each grounding wire clamp and extracts the unidimensional outlier of the grounding wire clamp. The exponentially weighted moving average is a statistical analysis method that can characterize the dynamic change trend of data and recent data fluctuations. It is an important tool in power system monitoring and maintenance. According to the exponentially weighted moving average of the status data of the grounding wire clamp at the current moment, it can be determined whether the status of the grounding wire clamp at the monitoring data point at the current moment is abnormal. The upper and lower thresholds of the exponentially weighted moving average of the status data of the grounding wire clamp at the current moment are determined based on the mean and standard deviation of the status data.

[0065] In this method, the processor monitors abnormal fluctuations in the status data of each grounding clamp and identifies potential problems by setting an upper threshold and a lower threshold. The processor can determine whether the grounding clamp at the monitoring data point at the current moment is abnormal based on whether the exponentially weighted moving average of the status data of the grounding clamp at the current moment is between the upper threshold and the lower threshold. This does not require a large amount of manpower to conduct regular inspections of the grounding clamp, thereby improving the efficiency of fault monitoring of the grounding clamp and the accuracy of fault detection of the grounding clamp, saving manpower and time.

[0066] In one embodiment, the processor calculates the density of the monitoring data points where the abnormal grounding wire clamps are located in each abnormal area cluster. The calculation formula for the density of the monitoring data points where the abnormal grounding wire clamps are located is:

[0067] in, The tightness of the monitoring data point where the abnormal grounding clamp is located. is the number of monitoring data points where the grounding clamp with abnormal status in the kth abnormal area cluster is located, is the monitoring data point where the abnormal grounding clamp is located at the center of the kth abnormal area cluster. is the monitoring data point where the I-th abnormal grounding clamp in the k-th abnormal area cluster is located.

[0068] Specifically, the closeness of the monitoring data points where the grounding wire clamp with abnormal status is located can reflect the correlation and similarity between the monitoring data points where the grounding wire clamp with abnormal status is located. When a grounding wire clamp is in an abnormal state, the position of the grounding wire clamp can be restricted to a smaller area. By calculating the closeness of the monitoring data points of the grounding wire clamp with abnormal status in the abnormal area cluster, the specific position of the grounding wire clamp with abnormal status can be more accurately located.

[0069] In this method, by continuously monitoring and analyzing the tightness of the monitoring data points where the grounding wire clamps in abnormal states are located, potential problems of each grounding wire clamp can be discovered and dealt with in a timely manner, thereby improving the accuracy and efficiency of detecting grounding wire clamps in abnormal states and improving the reliability of grounding wire clamp state detection.

[0070] In one implementation, the processor sorts the grounding wire clamps with abnormal status according to the number of single-dimensional abnormal values ​​of the status data of each grounding wire clamp with abnormal status in each abnormal region cluster.

[0071] Specifically, the above sorting rule is to sort from most to least according to the number of single-dimensional outliers. The staff will perform maintenance from the location of the grounding wire clamp with the most single-dimensional outliers to the location of the grounding wire clamp with the least single-dimensional outliers.

[0072] In this method, the processor sorts the status data of each abnormal grounding wire clamp in each abnormal area cluster from most to least according to the number of single-dimensional abnormal values. This method effectively identifies the most likely fault source (the monitoring data point where the abnormal grounding wire clamp is located), significantly improves the operation and maintenance efficiency, improves the safety and reliability of the distribution network, reduces costs, and enhances the data processing and analysis capabilities of the processor, thereby realizing the intelligent and automated management of the distribution network.
