Description

Technical Field

[0001] The present invention relates to the field of lightning protection grounding systems for power plants, and in particular to a method, system, medium and equipment for analyzing and displaying the corrosion state of a grounding grid. Background Art

[0002] In the field of lightning protection and grounding systems in power plants, researching and implementing a method and system for analyzing and displaying the corrosion status of grounding grids is extremely important for ensuring the safe and stable operation of power systems. By real-time monitoring and evaluating the degree of corrosion of grounding grids, not only can potential safety hazards be discovered in a timely manner, equipment failures or safety accidents caused by grounding grid corrosion can be prevented, but also the service life of the grounding grid can be effectively extended and maintenance costs can be reduced. In addition, the application of this analysis and display technology can help improve the intelligent management level of power plants and provide data support for scientific decision-making, thereby ensuring the continuity and reliability of power supply.

[0003] The existing analysis and display of the corrosion status of the grounding grid mainly rely on manual inspection and maintenance, which is inefficient and prone to missed inspections. The technical difficulties and key points mainly include how to achieve real-time monitoring of the grounding grid, how to accurately evaluate the corrosion status, and how to effectively display the monitoring results so as to take maintenance measures in a timely manner. Specifically, traditional manual inspection requires digging up the metal grounding grid for direct observation or using simple test tools to evaluate the degree of corrosion, which is not only time-consuming and labor-intensive, but also easy to cause secondary damage to the equipment. In addition, due to the lack of effective data analysis methods, it is difficult for traditional methods to fully consider the historical and real-time usage status of the grounding grid, resulting in insufficient accuracy and comprehensiveness of the corrosion status assessment. In order to solve these problems, the existing technology has gradually introduced a grounding grid corrosion status assessment method based on digital twins, which realizes real-time monitoring and analysis of its various parameters and status by establishing a digital model of the grounding grid. This method can improve the efficiency and accuracy of the assessment, but there are still some challenges, such as how to ensure the authenticity and integrity of the data, how to comprehensively analyze the different historical and real-time usage status of the grounding grid, and how to intuitively display the complex data analysis results to the operator. In general, although the existing technology has achieved the analysis and display of the corrosion status of the grounding grid to a certain extent, it still faces many technical and implementation challenges and requires continuous exploration and improvement.

[0093] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0094] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0095] According to a first aspect of an embodiment of the present invention, a method for analyzing and displaying the corrosion status of a grounding grid is provided.

[0096] Figure 1 The present invention is a flowchart of a method for analyzing and displaying the corrosion status of a grounding grid according to an embodiment of the present invention.

[0097] In one or more embodiments, preferably, the grounding grid corrosion status analysis and display method includes:

[0098] S101. Install a sensor network at key nodes of the grounding grid to collect grounding grid data in real time;

[0099] S102, performing preliminary processing on the received grounding grid data at the data processing center;

[0100] S103, analyzing the current mode as one of a current fluctuation mode, an abnormal voltage fluctuation mode, and a temperature change mode according to the preliminarily processed grounding grid data, and determining the corrosion state of the grounding grid;

[0101] S104, perform feature analysis on the corrosion state and learn to identify potential corrosion patterns;

[0102] S105. Combine the historical usage status and maintenance records of the grounding grid to form a comprehensive evaluation score;

[0103] S106. Based on the comprehensive evaluation score, the comprehensive evaluation score and the corrosion mode are intuitively displayed through a human-computer interaction interface.

[0104] In an embodiment of the present invention, key parameters such as current, voltage and temperature of the grounding grid are first collected in real time through a sensor network, and then the data is transmitted to a data processing center for preliminary analysis. At the data processing center, the received data is processed using advanced data fusion algorithms to eliminate noise and extract useful information. Next, the processed data is analyzed using a machine learning model to identify potential corrosion patterns. In addition, the system also considers the historical usage status and maintenance records of the grounding grid to more comprehensively assess its current condition. Finally, the analysis results are intuitively presented to operators in the form of charts or reports through a user-friendly interface, allowing them to quickly understand the health of the grounding grid and take appropriate maintenance measures as needed.

[0105] Figure 2 The present invention is a flow chart of a method for analyzing and displaying the corrosion status of a grounding grid in one embodiment of the present invention, in which a sensor network is installed at key nodes of the grounding grid to collect grounding grid data in real time.

[0106] like Figure 2 As shown, in one or more embodiments, preferably, the sensor network is installed at the key nodes of the grounding grid for real-time grounding grid data, specifically including:

[0107] S201, installing sensors at preset positions of the grounding grid, including current sensors, voltage sensors, and temperature sensors;

[0108] S202, the sensor collects grounding grid data in real time, and transmits the collected grounding grid data to the data processing center in real time through wireless communication technology;

[0109] S203: The data processing center receives grounding grid data, where the received grounding grid data includes a timestamp, a current value, a voltage value, and a temperature value.

[0110] In a specific embodiment of the present invention, in order to realize real-time monitoring and analysis of the corrosion state of the grounding grid of the lightning protection grounding system of a power plant, it is first necessary to install a sensor network at the key nodes of the grounding grid. These key nodes are determined in advance by in-depth analysis of the structure and operating characteristics of the grounding grid, and they can represent the operating status of the entire grounding grid. At each key node, high-precision current sensors, voltage sensors and temperature sensors are installed. These sensors can accurately measure key parameters such as current, voltage and temperature in the grounding grid. The design and selection of sensors need to take into account the actual operating environment and measurement requirements of the grounding grid to ensure that they can work stably in harsh environments and have high measurement accuracy and reliability. The sensor will collect data in real time (or regularly) and transmit the collected data to the data processing center in real time through wireless communication technology. Wireless communication technology can use short-distance wireless communication protocols such as Wi-Fi, Bluetooth, ZigBee, or long-distance wireless communication technologies such as 4G / 5G, depending on the scale of the grounding grid and the needs of data transmission. During data transmission, it is necessary to ensure the security and integrity of the data to avoid data tampering or loss. The grounding grid data received by the data processing center includes information such as timestamp, current value, voltage value and temperature value. The timestamp is used to record the time point of data collection so that it can accurately correspond to the specific time period when the data is analyzed later. The current value, voltage value and temperature value are the key parameters used to evaluate the corrosion state of the grounding grid. Through real-time monitoring and analysis of these data, abnormal conditions in the grounding grid, such as excessive current, abnormal voltage or excessive temperature, can be discovered in time, so as to determine whether the grounding grid has corrosion or other faults. For example, when the current value of a key node received by the data processing center suddenly increases, it may mean that the grounding grid near the node has corroded, resulting in an increase in grounding resistance, which in turn causes a change in current. At this time, the data processing center can immediately issue an early warning signal to remind maintenance personnel to check and handle it. At the same time, through the analysis of historical data, the future corrosion trend of the grounding grid can also be predicted, providing a basis for formulating preventive maintenance strategies.

[0111] Figure 3 The present invention is a flowchart of a method for analyzing and displaying the corrosion status of a grounding grid in accordance with an embodiment of the present invention, in which a data processing center performs preliminary processing on received grounding grid data.

[0112] like Figure 3 As shown, in one or more embodiments, preferably, the data processing center performs preliminary processing on the received grounding grid data, specifically including:

[0113] S301, performing denoising processing on the grounding grid data, and removing high-frequency noise by using a sliding average filter;

[0114] S302, classifying the grounding grid data, and normalizing the classified grounding grid data;

[0115] S303, detecting the normalized grounding grid data and removing abnormal values, wherein the abnormal values ​​are data satisfying the first calculation formula;

[0116] The first calculation formula is:

[0117] |Tq-Td|÷Td>VY

[0118] |Th-Td|÷Td>VY

[0119] Among them, Tq is the previous data, Th is the next data, Td is the current data, and VY is the preset comparison value.

[0120] In an embodiment of the present invention, the data processing center performs preliminary processing on the received grounding grid data to eliminate noise and outliers and improve the accuracy and reliability of the data. First, the grounding grid data is denoised using a sliding average filter to remove high-frequency noise. The sliding average filter is a commonly used digital filtering method that smoothes the data by calculating the average value of the data in the data window, thereby reducing the impact of noise.

[0121] Next, the de-noised grounding grid data is classified. According to the structure and operating characteristics of the grounding grid, the data is divided into different categories, such as current data, voltage data, and temperature data. The uniformly classified data is normalized, that is, the data is scaled to a specific range, usually [0,1] or [-1,1]. Normalization helps to eliminate the differences between different dimensions and magnitudes, making data of different categories comparable. Then, the normalized data is detected and outliers are removed. An outlier refers to a data point that deviates significantly from the normal range, which may be caused by sensor failure, data transmission error or other reasons. In this embodiment, the first calculation formula is used to determine whether the data is an outlier. The first calculation formula is as follows: |Tq-Td|÷Td>VY; |Th-Td|÷Td>VY; where Tq is the previous data, Th is the next data, Td is the current data, and VY is the preset comparison value. If the difference between the current data and the previous and next data exceeds the preset comparison value VY, the data is considered to be an outlier and is removed from the data set. In this way, the influence of outliers on subsequent analysis results can be effectively eliminated. For example, suppose that the current data of the grounding grid is de-noised and normalized to obtain a set of data sequences. According to the first calculation formula, it is found that the difference between the current value of a certain data point and the two previous and next data points exceeds the preset comparison value VY. At this time, the current value of the data point can be considered as an outlier and removed from the data set. In this way, the remaining current data will more accurately reflect the actual operating status of the grounding grid.

[0122] Figure 4 It is a flowchart of a grounding grid corrosion status analysis and display method in an embodiment of the present invention, which determines the corrosion status of the grounding grid by analyzing the current mode as one of the current fluctuation mode, the abnormal voltage fluctuation mode, and the temperature change mode based on the grounding grid data after preliminary processing.

[0123] like Figure 4 As shown, in one or more embodiments, preferably, the method of analyzing the current mode as one of the current fluctuation mode, the abnormal voltage fluctuation mode, and the temperature change mode according to the grounding grid data after preliminary processing, and determining the corrosion state of the grounding grid specifically includes:

[0124] S401, extracting grounding grid data generated by current fluctuation, voltage fluctuation and temperature fluctuation obtained within a past period of time T1 (for example, within 1 month); the grounding grid data also includes the grounding grid resistance to ground;

[0125] S402, calculating a first sensitivity of the grounding grid to ground resistance using a second calculation formula;

[0126] S403, calculating the second sensitivity of the grounding grid to the ground resistance using a third calculation formula;

[0127] S404, calculating the third sensitivity of the grounding grid to the ground resistance using a fourth calculation formula;

[0128] S405, when the average value of the first sensitivity, the second sensitivity or the third sensitivity in the past period of time T1 is higher than the preset comparison value, it is considered to correspond to the current fluctuation mode, the voltage abnormal fluctuation mode or the temperature change mode respectively;

[0129] S406: When in the current fluctuation mode, the voltage abnormal fluctuation mode or the temperature change mode, the video image of the corresponding grounding grid prone to corrosion area is recorded as the corrosion state.

[0130] The second calculation formula is:

[0131] M1=B÷Cb

[0132] Wherein, M1 is the first sensitivity of the grounding grid to the ground resistance, B is the fluctuation of the grounding grid to the ground resistance within a period of time T2 (T2<T1, for example, within 1 hour), and Cb is the current fluctuation;

[0133] The third calculation formula is:

[0134] M2=B÷Vb

[0135] Among them, M2 is the second sensitivity of the grounding grid to the ground resistance, and Vb is the voltage fluctuation;

[0136] The fourth calculation formula is:

[0137] M3=B÷Tb

[0138] Among them, M3 is the third sensitivity of the grounding grid to the ground resistance, and Tb is the temperature fluctuation.

[0139] In an embodiment of the present invention, in order to analyze the corrosion state of the grounding grid, the grounding grid data under current fluctuation, voltage fluctuation and temperature fluctuation obtained in the past period of time T1 are first extracted. These data include the grounding grid resistance to ground. Next, the first sensitivity of the grounding grid to the ground resistance is calculated using the second calculation formula. The second calculation formula is: M1 = B ÷ Cb, where M1 is the first sensitivity of the grounding grid to the ground resistance, B is the fluctuation of the grounding grid resistance to ground within a period of time T2, and Cb is the current fluctuation. Through this formula, the degree of influence of current fluctuation on the grounding grid resistance to ground can be quantified. Similarly, the second sensitivity of the grounding grid to the ground resistance is calculated using the third calculation formula. The third calculation formula is: M2 = B ÷ Vb, where M2 is the second sensitivity of the grounding grid to the ground resistance, and Vb is the voltage fluctuation. This formula is used to measure the influence of voltage fluctuation on the grounding grid resistance to ground. Then, the third sensitivity of the grounding grid to the ground resistance is calculated using the fourth calculation formula. The fourth calculation formula is: M3 = B ÷ Tb, where M3 is the third sensitivity of the grounding grid to the ground resistance, and Tb is the temperature fluctuation. This formula is used to evaluate the impact of temperature fluctuations on the ground resistance of the grounding grid. Next, it is determined whether the average value of the first sensitivity, the second sensitivity, or the third sensitivity in the past period of time T1 is higher than the preset comparison value. If the average value of the first sensitivity is higher than the comparison value, the current mode is considered to be the current fluctuation mode; if the average value of the second sensitivity is higher than the comparison value, the current mode is considered to be the abnormal voltage fluctuation mode; if the average value of the third sensitivity is higher than the comparison value, the current mode is considered to be the temperature change mode. Finally, after the current mode is determined, the video images of the corresponding grounding grid prone to corrosion area are recorded as evidence of the corrosion state. These video images can be used for subsequent analysis and processing to further understand the corrosion of the grounding grid. For example, suppose that in the past month, it is found that the average value of the first sensitivity is significantly higher than the comparison value, while the average values ​​of the second sensitivity and the third sensitivity do not exceed the comparison value. Based on this result, it can be determined that the current mode is the current fluctuation mode, and the video images of the grounding grid prone to corrosion area under this mode are recorded. These video images will help maintenance personnel to more intuitively understand the corrosion status of the grounding grid, so as to take corresponding maintenance measures.

[0140] Figure 5 It is a flow chart of performing characteristic analysis on the corrosion state and learning to identify potential corrosion patterns in a grounding grid corrosion state analysis and display method according to an embodiment of the present invention.

[0141] like Figure 5 As shown, in one or more embodiments, preferably, the feature analysis of the corrosion state and learning to identify potential corrosion patterns specifically include:

[0142] S501, obtaining a picture of the corrosion state and comparing common corrosion features;

[0143] S502: When the image similarity reaches a preset value, it is considered that the image is currently in corrosion under a corresponding model, wherein the corrosion under the corresponding model includes voltage sensitive mode corrosion, current sensitive mode corrosion and temperature sensitive mode corrosion.

[0144] In an embodiment of the present invention, in order to identify and analyze the corrosion state of the grounding grid, firstly, pictures of the corrosion state are obtained. These pictures are taken by cameras or other image acquisition devices installed at key nodes of the grounding grid, and can intuitively reflect the corrosion situation on the surface of the grounding grid. Next, common corrosion features are compared. By comparing the pictures of the corrosion state with the pictures in the predefined common corrosion feature library, it can be determined whether the current grounding grid has been corroded. Common corrosion features may include rust, pits, cracks, etc. In the comparison process, image processing technology, such as edge detection, texture analysis, etc., is used to extract feature information in the picture and match it with the pictures in the common corrosion feature library. When the picture similarity reaches a preset value, it is considered that the current corrosion is under the corresponding model. This preset value is set based on experience and is used to control the accuracy and sensitivity of recognition. If the similarity is too low, some actual corrosion may be missed; if the similarity is too high, it may be misjudged as corrosion. Therefore, the preset value needs to be adjusted according to the actual situation. The corrosion under the corresponding model includes voltage-sensitive, current-sensitive and temperature-sensitive mode corrosion. This means that according to different corrosion features, the corrosion state of the grounding grid can be divided into different modes. For example, if the corrosion characteristics are mainly manifested as large voltage fluctuations, it may belong to voltage-sensitive mode corrosion; if it is mainly manifested as large current fluctuations, it may belong to current-sensitive mode corrosion; if it is mainly manifested as large temperature changes, it may belong to temperature-sensitive mode corrosion. By analyzing and studying the corrosion status under different modes, we can further understand the laws and characteristics of grounding grid corrosion, so as to formulate more effective prevention and maintenance strategies. For example, if it is found that the corrosion frequency under a certain mode is high or the degree is serious, the maintenance and monitoring of the area can be strengthened in a targeted manner to reduce the risk of corrosion.

[0166] Among them, zhpg is the comprehensive evaluation score.

[0167] In an embodiment of the present invention, in order to comprehensively evaluate the corrosion state of the grounding grid, the historical usage data and maintenance status data of all grounding grids are first extracted. These data include information such as the usage time, usage environment, and maintenance history of the grounding grid, which are essential for analyzing the corrosion state of the grounding grid. Next, for each voltage sensitive mode encountered, the current sensitivity comprehensive score is extracted using the fifth calculation formula.
