Description

Technical Field

[0001] The present invention relates to the technical field of design of a traveling wave monitoring terminal, and in particular to a design method and system of a traveling wave monitoring terminal. Background Art

[0002] Transmission and distribution lines are prone to insulator degradation, contamination, floating foreign objects, etc., which can lead to weakened insulation strength between the high-voltage side conductors and the ground wires and towers at the ground potential, causing hidden discharges. If not cleared in time, it will develop into a fault and eventually cause the line to trip and stop operating, resulting in significant economic losses and safety risks.

[0003] In order to accurately and timely identify and eliminate discharges on the line, it is necessary to first identify the existence and type of hidden discharges on the line. Currently, most transmission and distribution lines of various voltage levels have installed distributed traveling wave fault locating devices, which collect high-frequency discharge traveling waves generated and propagated from the discharge point at both ends of the line, calculate their characteristics, and compare and determine whether they have abnormal characteristics, so as to identify the existence and type of discharge, and notify the line operation and maintenance personnel to carry out maintenance work.

[0004] At present, similar technologies mainly extract high-frequency discharge waveform fragments, calculate specified features such as amplitude, phase, power frequency accompanying periodicity, etc., and use pattern classification algorithms such as decision trees, support vector machines, neural networks, etc. to finally output the existence or type label of hidden dangers. However, in reality, the amount of transmission line hidden danger traveling wave signals collected is very large. With the advancement of technology, the scope and accuracy of collection are constantly improving, but the huge amount of data leads to very high transmission pressure. Useful traveling wave signals are easily ignored, resulting in a decrease in positioning accuracy and recognition rate. Therefore, it is necessary to design an intelligent traveling wave monitoring terminal to solve the problem of large data transmission volume. Summary of the invention

[0049] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. 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.

[0050] Example 1

[0051] Reference Figure 1-Figure 7 , which is the first embodiment of the present invention, and which provides a design method and system for a traveling wave monitoring terminal, including:

[0052] There are some problems in the existing related technologies. For example, the response speed of the monitoring terminal is not fast enough to capture the changes of the traveling wave signal in a timely and accurate manner, resulting in delayed and inaccurate monitoring results. In addition, the monitoring system in the existing technology often lacks an effective redundancy mechanism. Once the monitoring equipment fails, the stability and reliability of the entire system will be seriously affected.

[0053] The present application provides a method that can effectively solve the above-mentioned problems. Next, a design method for implementing the traveling wave monitoring terminal will be described in detail in combination with multiple embodiments.

[0054] Figure 1 A method flow chart of a design method and system of a traveling wave monitoring terminal is shown, including:

[0055] S101, configuring a first preprocessing module for performing a first preprocessing on target first discharge traveling wave data;

[0056] In an embodiment of the present application, the first preprocessing module configured to perform a first preprocessing on the target first discharge traveling wave data includes:

[0057] The first preprocessing is used to determine whether the target first discharge traveling wave data is a hidden danger traveling wave;

[0058] And establish the first wave management table according to the judgment result.

[0059] In an optional embodiment, the target first discharge traveling wave data may include multiple parameters, such as voltage, current, frequency, and phase angle, etc. These parameters can fully reflect the characteristics of the discharge traveling wave. By collecting these parameters, the nature of the traveling wave can be more accurately analyzed and judged, thereby providing richer data support for traveling wave monitoring.

[0060] In an optional embodiment, the first preprocessing may further include performing noise filtering on the target first discharge traveling wave data to improve the accuracy of the data. The noise filtering may use digital filtering technology, such as low-pass filtering, high-pass filtering, band-pass filtering or band-stop filtering, to remove noise components in the data and ensure the reliability of subsequent analysis.

[0061] In an optional embodiment, the first preprocessing can also normalize the data so that data of different magnitudes can be compared and analyzed under the same standard. Through these preprocessing steps, more accurate and consistent data input can be provided to the traveling wave monitoring terminal, thereby improving the monitoring efficiency and accuracy of the entire system.

[0062] In an optional embodiment, the first preprocessing is used to determine whether the target first discharge traveling wave data is a hidden danger traveling wave, and to identify potential hidden danger traveling waves by setting a series of threshold conditions, such as voltage exceeding a specific value, current mutation, abnormal frequency fluctuation, or significant change in phase angle, etc. When the detected data meets these conditions, the system will issue an alarm to prompt the operator to conduct further inspection and processing.

[0063] In an optional embodiment, the first preprocessing can also combine historical data and machine learning algorithms to improve the recognition accuracy of hidden danger traveling waves through pattern recognition. Through these methods, the traveling wave monitoring terminal can timely detect and warn of possible power system failures, thereby ensuring the stable operation of the power system.

[0064] In the embodiment of the present application, the first preprocessing also includes waveform feature calculation, which mainly realizes the feature recognition of the traveling wave and is used to eliminate the traveling wave that does not meet the hidden danger discharge feature. The waveform is passed through multiple parallel feature calculation algorithms in an assembly line manner to obtain a conclusion on whether it meets the hidden danger discharge waveform. Finally, the calculation result is updated to the traveling wave management table for use by other modules, such as Figure 2 As shown;

[0065] It should be noted that according to the actual operation situation, the existing interference waveform characteristics are statistically analyzed, and a variety of characteristic calculation algorithms are extracted. The judgment results of all calculation algorithms are statistically analyzed to obtain the final judgment result of the judgment waveform.

[0066] It should be noted that the feature calculation algorithm in the current system of this application includes: spike pulse determination, interval time determination, duration determination, continuous trigger determination, periodicity determination, and clock jitter determination. The results determined after the algorithm calculation are updated to the traveling wave event management table for combining priorities with other modules.

[0067] It should also be noted that the first preprocessing module configured to perform a first preprocessing on the target first discharge traveling wave data improves the efficiency of traveling wave data processing, because the first preprocessing module can quickly identify and eliminate traveling wave data that does not meet the conditions. Through the waveform feature calculation of the first preprocessing module, traveling waves with hidden danger discharge characteristics can be more accurately identified, thereby reducing false alarms and missed alarms. The introduction of the first preprocessing module enables the traveling wave monitoring terminal to update the traveling wave management table in real time, providing timely and accurate data support for subsequent analysis and decision-making. The setting of this module helps to simplify the subsequent processing flow, because the preprocessed traveling wave data has been preliminarily screened and classified, which facilitates other modules to perform more in-depth analysis and processing.

[0068] S102, configuring a first threshold determination module for performing a first threshold determination on the result after the first preprocessing;

[0069] In an embodiment of the present application, the first threshold determination module configured to perform a first threshold determination on the result after the first preprocessing includes:

[0070] Performing a second preprocessing on the traveling wave waveform of the first traveling wave management table;

[0071] Comparing the second preprocessed traveling wave waveform with a preset first threshold;

[0072] The first wave management table is updated according to the comparison result to obtain the second wave management table.

[0073] In an optional embodiment, the second preprocessing may include performing frequency analysis on the traveling wave waveform to identify signal characteristics within a specific frequency range; using digital filtering technology to filter out noise and non-target frequency components to improve signal purity; reconstructing the filtered traveling wave waveform through waveform reconstruction technology to restore the original form of the traveling wave; finally, comprehensively analyzing the reconstructed traveling wave waveform data with the output of the first threshold judgment module to further confirm the characteristics and status of the traveling wave.

[0074] In an optional embodiment, multiple threshold judgment modules can be set, each module corresponding to different traveling wave characteristics and states. These modules can work in parallel to improve the efficiency and accuracy of traveling wave monitoring. Each module can independently analyze the traveling wave waveform and make a judgment based on its specific threshold condition.

[0075] In an optional embodiment, a central processing unit may also be included to integrate the analysis results of each module and make a final traveling wave monitoring decision. In this way, the traveling wave monitoring terminal can more comprehensively cover various possible traveling wave abnormal situations, thereby improving the stability and safety of the entire power system.

[0076] In an optional embodiment, the preset first threshold value can be pre-set based on the statistical characteristics of the traveling wave signal to distinguish between normal traveling waves and abnormal traveling waves. The threshold value can be fixed or dynamically adjusted according to real-time monitoring data. For example, a threshold value can be set, and when the amplitude of the traveling wave signal exceeds this threshold value, the system will consider that an abnormal situation exists. In addition, multiple threshold values ​​can be set to distinguish different degrees of abnormal situations, thereby achieving more sophisticated monitoring and early warning.

[0077] In the embodiment of the present application, in actual operation, there are a large number of small traveling waves on the transmission line itself, especially for transmission lines with voltages above 110kV. The characteristics of the traveling waves are highly similar to the characteristics of the hidden danger discharge waveform and cannot be filtered out from the characteristics, as follows Figure 3 shown.

[0078] Since the amplitude of the interference waveform is generally small, it can be distinguished from the amplitude perspective. The waveform threshold judgment function is set. The execution process is as follows: Figure 4 As shown:

[0079] In an optional embodiment, during the analog-to-digital conversion process, the same analog quantity is amplified by different magnifications and then enters the ADC for sampling. The program needs to identify the channel number and then convert the amplification factor to obtain the highest precision sampling value. Therefore, the amplitude of the current waveform time can be obtained by performing full-length amplitude statistics on the continuous discharge waveform event and then multiplying it by the amplification factor corresponding to the channel number. The maximum amplitude of the waveform is compared with the set threshold parameter to obtain the amplitude comparison result, which is updated to the traveling wave event management table for other modules to combine priorities.

[0080] It should be noted that the first threshold judgment module configured to perform a first threshold judgment on the result after the first preprocessing can effectively identify and filter out interference waveforms with smaller amplitudes through this module, thereby reducing false alarms. The setting of the first threshold judgment module enables the system to dynamically adjust the threshold according to the actual operating conditions, thereby improving the accuracy and reliability of monitoring. The introduction of this module can also help the system distinguish between traveling waves during normal operation and potential fault traveling waves, providing accurate data support for subsequent fault location and early warning.

[0081] S103, configuring a first data storage module for storing the discharge traveling wave that meets the judgment condition after the first threshold is judged;

[0082] In an embodiment of the present application, the first data storage module configured to store the discharge traveling wave that meets the judgment condition after the first threshold judgment includes:

[0083] determining a first redundancy priority;

[0084] Storing data according to the priority order of the first redundancy priority level;

[0085] The first redundancy priority is determined according to a processing result of the first preprocessing module and a judgment result of the first threshold judgment module.

[0086] In an optional embodiment, the first redundancy priority can be designed in different ways to ensure the efficiency and reliability of data storage. For example, the priority can be set based on the amplitude of the discharge traveling wave, and the discharge traveling wave with a larger amplitude has a higher storage priority to ensure that critical data will not be lost due to insufficient storage space.

[0087] In an optional embodiment, the frequency of the discharge traveling wave can also be considered. A high-frequency discharge traveling wave may indicate a potential fault, and therefore should also be given a higher storage priority. Through such a design, the system can manage data storage more intelligently, ensuring that the most valuable data for fault diagnosis and early warning is saved first under limited storage resources.

[0088] In the embodiment of the present application, the first redundancy priority is determined according to the processing result of the first pre-processing module and the judgment result of the first threshold judgment module. The specific redundancy priority sorting block diagram is as follows: Figure 5 As shown:

[0089] In the embodiment of the present application, the sampling rate of the second-generation monitoring device is used, and the traveling wave is sampled at a high speed of not less than 2M sampling rate, and the trigger detection is performed in real time, and the trigger waveform is saved. However, the traveling wave sending channel rate is slow, resulting in the continuous accumulation of traveling wave trigger events, causing transition redundancy and failure to process and analyze in time. Redundant priority sorting is to obtain the results of the previous several feature detections from the traveling wave event management table, combine the priorities, and eliminate the waveform with the lowest priority to cache the new trigger waveform. The priority sorting method is shown in the following table:

[0090] Table 1 Priority combination table

[0091] Feature calculation Waveform Threshold Final Priority conform to conform to 3 conform to Not Compliant 2 Not Compliant Not Compliant 1

[0092] In an embodiment of the present application, storing data according to the priority order of the first redundancy priority level includes:

[0093] If the first data storage module is fully loaded, the discharge traveling wave with the lowest priority is eliminated according to the priority order;

[0094] The newly generated discharge traveling wave is stored in the corresponding position.

[0095] It should be noted that the first data storage module configured to store the discharge traveling waves that meet the judgment conditions after the first threshold judgment improves data processing efficiency, because only the traveling wave data that meets specific conditions will be stored, reducing unnecessary data processing and storage burdens. Optimize the use of storage space to ensure that the storage space is effectively used, and give priority to saving the most valuable data for monitoring and analysis. Speed ​​up data retrieval, because the data storage module only contains traveling wave data that meets specific conditions, so that relevant information can be quickly located and retrieved when needed. Facilitate subsequent data analysis and processing, because important data has been pre-screened in the data storage module, which facilitates subsequent waveform analysis and fault diagnosis. Enhance the real-time performance of the system. By reducing the amount of data that needs to be processed, the system can respond to new trigger events more quickly, thereby improving overall monitoring efficiency.

[0096] S104, configuring a first data sending module for sending the discharge traveling wave stored in the first data storage module.

[0097] In an embodiment of the present application, the first data sending module configured to send the discharge traveling wave stored in the first data storage module includes:

[0098] Determine a first sending priority;

[0099] Sending data according to the priority order of the first sending priority;

[0100] The first sending priority is the same as the first redundancy priority.

[0101] In an optional embodiment, the first transmission priority can be designed in different ways, for example, by setting the priority according to the importance and urgency of the traveling wave data. Data with higher priority can be sent first to ensure that key information is not delayed due to the large amount of data. In addition, the priority setting can also be dynamically adjusted according to actual monitoring needs to adapt to different monitoring environments and conditions. In this way, the efficiency of data transmission can be further optimized, ensuring that the monitoring system can respond quickly at critical moments, and improving the accuracy and reliability of traveling wave monitoring.

[0102] In this embodiment of the present application, the first sending priority and the first redundancy priority may be different.

[0103] In an optional embodiment, when the first sending priority is different from the first redundancy priority, the system may implement a priority adjustment strategy, which is intended to optimize the efficiency and reliability of data transmission.

[0104] In an optional embodiment, when the first transmission priority is higher than the first redundancy priority, the system will give priority to processing data packets with higher priorities to ensure rapid delivery of critical information.

[0105] In an optional embodiment, on the contrary, if the first sending priority is lower than the first redundancy priority, the system will give priority to sending redundant data to enhance the fault tolerance of data transmission.

[0106] It should be noted that the implementation of this strategy enables the system to flexibly adjust the order in which data packets are sent according to the actual network conditions and the importance of the data, thereby ensuring the integrity and reliability of the data while ensuring the efficiency of data transmission.

[0107] like Figure 6 As shown, the traveling wave event management table: This is the starting point of the process, indicating the recording and management of traveling wave events. Waveform preprocessing: Preprocess the waveform data of the traveling wave event, which may be to remove noise or convert the data format. Filter high priority for message storage: Filter high priority events from the preprocessed data and store the messages. GPRS sending module intervention: Send the filtered messages through the GPRS (General Packet Radio Service) module. Upload the message to the system background: The last step is to upload the message to the system background to complete the entire process.

[0108] In summary, the present invention proposes a design method for a traveling wave monitoring terminal, which is configured with a first preprocessing module for performing a first preprocessing on the target first discharge traveling wave data; a first threshold judgment module for performing a first threshold judgment on the result after the first preprocessing; a first data storage module for storing the discharge traveling wave that meets the judgment condition after the first threshold judgment; and a first data sending module for sending the discharge traveling wave stored in the first data storage module. The accuracy and efficiency of traveling wave monitoring are improved. By setting the first preprocessing module, noise interference can be effectively removed to ensure the purity of data. Real-time monitoring and rapid response are achieved. The first threshold judgment module can quickly identify abnormal signals and trigger alarms and data storage in time. Data management is optimized. The introduction of the first data storage module enables important data to be properly stored, which is convenient for subsequent analysis and fault diagnosis. Data sharing and remote transmission capabilities are strengthened. The configuration of the first data sending module enables monitoring data to be transmitted to a remote monitoring center in real time, which is convenient for centralized management and decision support. Based on the principles of intelligent perception, on-demand startup, and energy-saving standby, a monitoring terminal that can use edge computing to process a large amount of hidden danger discharge waveform data is designed and developed. The large-scale services that were originally handled entirely by the background central node are decomposed and cut into smaller and more manageable parts, which are distributed to edge nodes for processing. This can speed up the processing and transmission of hidden danger discharge data, reduce delays, and achieve local storage, local analysis, on-demand return and real-time monitoring, providing reliable support and guarantee for the "early prevention, early detection, and early response" of transmission line hidden danger monitoring. At the same time, only valuable discharge waveform data related to hidden danger discharge is saved, and a large amount of redundant data is removed, which greatly reduces the amount of data storage, storage space consumption and application costs.

[0109] Example 2

[0110] In a preferred embodiment, the following actual modules and architectures can be designed according to the above method:

[0111] 1) Hardware selection: Compare and analyze the application scenarios of X86 and ARM CPU technology frameworks, combine the boards of major manufacturers and their respective advantages and disadvantages, select CPU central processing units with low-power architecture, and equip them with AI computing power suitable for the hidden danger discharge monitoring business to ensure long-term stable operation;

[0112] 2) Software architecture: The edge computing module needs to have built-in hidden danger discharge waveform data and power frequency waveform data acquisition and analysis software, and realize long-term continuous line hidden danger monitoring and early warning through intelligent processing and analysis such as waveform preprocessing, waveform feature extraction, and waveform feature recognition. Use advanced intelligent analysis algorithms, integrate target detection and recognition technology, start real-time data collection function when hidden danger discharge is detected, and keep dormant under normal circumstances.

[0113] After collecting the power frequency and discharge waveforms of the transmission line, it is very important to process and sort the waveform data. In order to prevent wave leakage or loss, or data redundancy causing transmission delays, the discharge traveling wave data needs to be effectively processed.

[0114] The traveling wave optimization logic in the edge computing module consists of four parts:

[0115] ① Waveform feature calculation: Starting from the characteristics of the intercepted waveform, it is determined whether the traveling wave meets the hidden danger discharge characteristics, which is used to filter out invalid waveforms.

[0116] ② Waveform threshold determination: obtain the amplitude and acquisition channel of the saved waveform, and compare them with the set hidden danger upload threshold.

[0117] ③ Redundant priority sorting: In order to ensure that the newly triggered discharge traveling wave can find storage space, it is necessary to continuously traverse the traveling wave event management table to find free space or cover it with the traveling wave with the lowest priority.

[0118] ④ Sending priority sorting: In actual applications, the speed of storing hidden danger discharge data is much faster than the sending speed. A sending priority sorting function is added to traverse the traveling wave event management table and select the traveling wave with the highest priority for sending to ensure reliable reporting of hidden danger discharge waveforms.
