Currently, substation electromagnetic environment testing technologies are showing a diversified trend. This includes traditional power outage testing and live-line testing, as well as intelligent testing using digital instruments. However, with the increasing complexity of substation equipment, electromagnetic environment testing also faces more technical challenges.

The commonly used testing equipment includes dedicated probes or electric and magnetic field testing instruments. Three-dimensional probes can measure the electric or magnetic field strength components in three mutually perpendicular directions at a point in space. However, the current testing has significant limitations.

The data storage system can be integrated onto server 104, or it can be located in the cloud or on another network server.

[0067] When the ambient humidity is greater than the first preset humidity threshold, server 104 adjusts the horizontal rotation speed of the electromagnetic probe according to the ambient humidity; according to the adjusted horizontal rotation speed of the electromagnetic probe, it trains an electromagnetic environment simulation model based on steady-state background test data and transient background test data; and uses the electromagnetic environment simulation model to obtain electromagnetic environment test data of the substation.

Head-mounted displays can be virtual reality (VR) devices, augmented reality (AR) devices, and smart glasses. The server 104 can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0069] In one exemplary embodiment, such as Figure 2 As shown, a method for testing the electromagnetic environment of a substation is provided, which is then applied to... Figure 1 Taking the server in the example, the explanation includes the following steps S202 to S214. Wherein:

[0070] Step S202: Determine the test location for the electromagnetic environment of the substation.

[0071] Specifically, firstly, key locations within the substation need to be identified, including but not limited to inlet / outlet lines, equipment areas, and control rooms. These areas are typically characterized by high electromagnetic radiation intensity or sensitivity to the electromagnetic environment. Non-frequency-selective broadband radiation meters and electromagnetic probes are installed at these key locations to monitor the electromagnetic environment in these areas. A combination of fixed-location and dynamic electromagnetic monitoring enables comprehensive monitoring of the substation's electromagnetic environment. When determining test locations, environmental factors such as humidity and temperature must be considered, as these factors may affect the propagation and measurement of electromagnetic radiation. Data is collected at the identified test locations, and then analyzed to assess the electromagnetic environment. Based on test results and environmental changes, test locations can be dynamically adjusted to ensure the continuous acquisition of accurate and comprehensive electromagnetic environment data.

[0072] Step S204: Conduct a steady-state background test at the test location to obtain steady-state background test data.

[0073] Specifically, the purpose of steady-state background testing is to obtain baseline data on the electromagnetic environment of the substation under normal operating conditions. This data will serve as a reference for subsequent transient testing to assess the impact of transient processes on the electromagnetic environment. By comparing steady-state background data and transient test data, the electromagnetic environment changes of the substation under different operating conditions can be evaluated. A non-frequency-selective broadband radiation meter is used to measure power frequency and radio frequency electric and magnetic fields. Multiple measurements are taken at key locations during normal substation operation to obtain stable background data. The data from multiple measurements are averaged to reduce random errors and obtain relatively stable background data. The steady-state background test data is recorded and stored for subsequent analysis and comparison.

[0074] Step S206: Obtain the ambient humidity at the test location.

[0075] Specifically, high humidity can increase the attenuation of electromagnetic waves propagating in the air, thus affecting the accuracy of measurement results. Humidity can also affect the electrical performance of measuring equipment, such as the sensitivity and stability of the probe. Based on the measured humidity value, test parameters, such as the test distance and the probe rotation rate, can be adjusted to reduce the impact of humidity on the test results. Humidity data can be used to calibrate measurement results, ensuring the accuracy and reliability of the data.

[0076] Humidity measurement method: Real-time humidity measurement can be performed at the test site using a hygrometer. Record the humidity measurements for subsequent analysis and data correction.

[0077] Step S208: When the ambient humidity is greater than the first preset humidity threshold, adjust the horizontal rotation speed of the electromagnetic probe according to the ambient humidity.

[0078] Specifically, based on the performance of the testing equipment and the characteristics of the testing environment, a first preset humidity threshold (e.g., 50%) is set. When the ambient humidity exceeds this threshold, additional measures are needed to ensure the accuracy of the test. Increased humidity may cause the propagation of electromagnetic waves in the air to attenuate, affecting the accuracy of the measurement. Humidity may affect the electrical performance of the measuring equipment, such as the sensitivity and stability of the electromagnetic probe. By increasing the rotation speed of the electromagnetic probe, the duration of the influence of humidity on the electromagnetic probe can be reduced, thereby reducing the negative impact of humidity on the test results. Increasing the rotation speed of the electromagnetic probe can improve the efficiency of the test and reduce the time required for the test. Record the humidity data before and after adjustment to facilitate subsequent analysis and verification of the adjustment effect. Analyze the test results after adjusting the rotation speed to ensure the accuracy and reliability of the test. Typically, the relationship between the probe rotation speed and humidity can be determined through linear fitting. Adjust the probe rotation speed to a new value to adapt to the current humidity conditions.

[0079] Step S210: Perform transient background testing at the test location according to the adjusted horizontal rotation rate of the electromagnetic probe to obtain transient background test data.

[0080] Specifically, transient background testing aims to capture instantaneous changes in the electromagnetic environment that may occur in a substation under normal operating conditions. These changes may be caused by factors such as equipment start-up and shutdown, load changes, etc. By comparing the data with steady-state background test data, the impact of these transient changes on the electromagnetic environment can be assessed.

[0081] Changes in ambient humidity can affect the propagation of electromagnetic waves and the performance of electromagnetic probes, thus requiring adjustment of the probe's rotation rate to accommodate these changes. Adjusting the rotation rate reduces the impact of humidity on probe performance and improves the accuracy of test data. During testing, ambient humidity is monitored in real time, and the probe's rotation rate is adjusted accordingly. Transient background testing is performed using the adjusted rotation rate to collect electromagnetic environment data. The collected transient background test data is recorded and stored for subsequent analysis. The transient background test data is analyzed to assess the stability and trends of the electromagnetic environment.

[0082] Step S212: Based on the steady-state background test data and the transient background test data, an electromagnetic environment simulation model is trained.

[0083] Specifically, firstly, the steady-state and transient background test data are preprocessed, including removing outliers and noise to ensure data quality and consistency. The data are then standardized to ensure they are on the same scale for easier comparison and analysis.

[0084] Then, key features are extracted from the preprocessed steady-state and transient background test data. These features represent the main attributes and changing trends of the electromagnetic environment. If the data dimensionality is too high, dimensionality reduction may be necessary to reduce computational complexity and improve the model's generalization ability. Based on the data characteristics and analysis objectives, a suitable simulation model, such as a machine learning model, a physical model, or a hybrid model, is selected. Model parameters, such as the learning rate and number of iterations, are set to optimize model performance. First, the model is trained using steady-state background test data to learn the basic laws of the electromagnetic environment. Then, transient background test data is added to the training process to enable the model to capture the dynamic changes in the electromagnetic environment.

[0085] Furthermore, methods such as cross-validation are used to evaluate the model's accuracy and generalization ability. The model's prediction error is analyzed to identify its shortcomings. Based on the validation results, model parameters are adjusted to optimize model performance.

[0086] Step S214: Use the electromagnetic environment simulation model to obtain electromagnetic environment test data of the substation.

[0087] Specifically, based on the required simulated substation operating conditions, input the corresponding parameters, such as equipment load, operating mode, and environmental conditions. Start the simulation model to perform calculations and simulations based on the input parameters and learned data patterns. The simulation model will output predicted electromagnetic environment data, including electric field strength, magnetic field strength, and radiation levels. This data is usually presented in digital form and can be further processed and analyzed. Compare the data generated by the simulation model with actual test data to evaluate the model's accuracy and reliability. Analyze the simulation results to identify trends and potential problems in the electromagnetic environment. Use the simulation results to assess the electromagnetic environment risks during substation operation, providing a basis for safety management. Based on the simulation analysis, propose measures to optimize the substation's electromagnetic environment, such as equipment layout adjustments and shielding measures. Continuously iterate and optimize the simulation model based on the comparison between simulation results and actual test data. Visualize the simulation data using charts, graphs, etc., for easy understanding and communication. As new test data is acquired, update the model's training data to improve its predictive capabilities.

[0088] The aforementioned substation electromagnetic environment testing method comprehensively assesses the substation's electromagnetic environment under different operating conditions by conducting steady-state and transient background tests at key test locations. Considering the impact of ambient humidity on electromagnetic testing and adjusting the electromagnetic probe's rotation speed accordingly reduces humidity interference with test results and improves data accuracy. Dynamically adjusting test parameters (such as the electromagnetic probe's horizontal rotation speed) to adapt to different environmental conditions enhances the method's flexibility and adaptability. The electromagnetic environment simulation model trained using steady-state and transient background test data can simulate and predict the substation's electromagnetic environment under various conditions, providing a scientific basis for decision-making. The simulation model helps identify potential electromagnetic environment risks, supporting substation safety management and risk prevention. Based on simulation results, substation equipment layout and operation can be optimized to reduce electromagnetic interference and improve overall system performance. Continuous use of the simulation model for testing and analysis enables long-term monitoring and trend analysis of the substation's electromagnetic environment, allowing for timely detection and resolution of potential problems.

[0089] In an exemplary embodiment, a steady-state background test is performed at a test site to obtain steady-state background test data, including:

[0090] During normal operation of the substation, a non-frequency-selective broadband radiation meter is used to measure the electromagnetic background values ​​of power frequency and radio frequency at the test location. Multiple measurements and averaging are performed to obtain steady-state background test data.

[0091] Specifically, the purpose of steady-state background testing is to obtain baseline data on the electromagnetic field levels of the substation under normal operating conditions. This data will serve as a comparison benchmark for subsequent transient or abnormal state tests.

[0092] The selected testing equipment is a non-frequency-selective broadband radiation meter, which can measure electromagnetic fields over a wide frequency range, including power frequency (usually referring to the 50 or 60 Hz power frequency) and radio frequency (radio frequency).

[0093] Multiple measurements were performed at the test site to ensure data representativeness and reduce random errors. The results of multiple measurements were averaged to obtain a more stable and reliable steady-state background value.

[0094] Testing power frequency electromagnetic fields: refers to measuring low-frequency electromagnetic fields that are directly related to the operation of power systems.

[0095] Testing radio frequency electromagnetic fields: refers to measuring high-frequency electromagnetic fields that may be generated by radio communication equipment or other electronic equipment.

[0096] Tests should be conducted in key areas within the substation, such as inbound and outbound lines, equipment areas, and control rooms. The electromagnetic field levels in these areas are crucial for assessing the substation's electromagnetic environment. Record the time, location, and equipment setup for each measurement to facilitate subsequent analysis and verification. Store the measurement data for long-term tracking and trend analysis. Based on steady-state background data, identify potential electromagnetic environment risks and develop corresponding management measures.

[0097] In this embodiment, by conducting steady-state background testing at the test site, detailed data on the electromagnetic field level of the substation under normal operating conditions can be obtained. This data is beneficial for accurately assessing the electromagnetic environment. The test equipment selected is a non-frequency-selective broadband radiation meter and an electromagnetic probe. This not only broadens the frequency range of the test but also allows for mobile dynamic testing at the test site, improving the comprehensiveness and flexibility of the test.

[0098] In one exemplary embodiment, such as Figure 3 As shown, adjusting the horizontal rotation speed of the electromagnetic probe according to the ambient humidity includes:

[0099] Step S302: Determine the influence adjustment coefficient of the electromagnetic probe based on the ambient humidity;

[0100] Step S304: Adjust the horizontal rotation speed of the electromagnetic probe according to the influence adjustment coefficient.

[0101] Specifically, the humidity influence adjustment coefficient is a coefficient determined based on changes in ambient humidity, used to adjust the horizontal rotation rate of the electromagnetic probe. The humidity influence adjustment coefficient is related to the linear fit between the probe's actual humidity change rate and its horizontal rotation rate. The increased horizontal rotation rate of the electromagnetic probe equals the standard horizontal rotation rate multiplied by the humidity influence adjustment coefficient.

[0102] The influence adjustment factor can be determined through experimental data, theoretical analysis, or historical data to reflect the specific impact of humidity on the performance of the electromagnetic probe. Based on the influence adjustment factor, the horizontal rotation rate of the electromagnetic probe is adjusted. If humidity increases, it may be necessary to increase the rotation rate to reduce the influence of humidity on the test results. This adjustment is dynamic; that is, the probe's rotation rate will adjust accordingly as the ambient humidity changes in real time.

[0103] First, a humidity sensor is used to monitor the humidity of the test environment in real time. An automatic control system automatically adjusts the probe's rotation speed based on the humidity monitoring results and a preset influence adjustment coefficient. Adjusting the rotation speed reduces the negative impact of humidity on electromagnetic test results and improves the accuracy of the test data. In high-humidity environments, increasing the rotation speed can accelerate the testing process and improve efficiency. This method is particularly important when conducting electromagnetic tests outdoors or in environments with significant humidity fluctuations. In situations requiring long-term monitoring of the electromagnetic environment, dynamically adjusting the probe's rotation speed ensures the continuity and reliability of the test data.

[0104] In this embodiment, this method ensures that the electromagnetic probe can provide accurate and reliable test data under different ambient humidity conditions, thereby improving the overall quality and efficiency of electromagnetic environment testing.

[0105] In an exemplary embodiment, when the ambient humidity is greater than a second preset humidity threshold, the test distance between the substation and the test location is shortened; wherein the second preset humidity threshold is greater than a first preset humidity threshold.

[0106] Specifically, the first preset humidity threshold is a lower humidity threshold. When the humidity exceeds this value, some measures may need to be taken, such as adjusting the rotation speed of the probe. The second preset humidity threshold is a higher humidity threshold (e.g., 60%). When the humidity exceeds this value, further measures are needed, such as shortening the test distance.

[0107] By shortening the distance between the substation and the test site, the distance electromagnetic waves travel through the air can be reduced, thus minimizing attenuation. Reducing the distance helps improve measurement accuracy because electromagnetic field strength decreases with distance. The test distance is adjusted dynamically, based on real-time humidity monitoring results to determine whether a shorter distance is necessary. Safety factors must also be considered when adjusting the test distance to ensure the safety of test personnel and equipment.

[0108] The specific operation involves using a humidity sensor to monitor the humidity of the test environment in real time. When the humidity exceeds a second preset humidity threshold, the test distance is shortened according to a predetermined strategy. An automatic control system can be developed to automatically adjust the test distance based on humidity monitoring results. In some cases, the test distance can also be manually adjusted by the tester based on humidity readings. By shortening the test distance, the quality of electromagnetic environment test data obtained under high humidity conditions can be improved. This method enhances the adaptability of the testing method to environmental changes, ensuring reliable test results under different humidity conditions. This method is particularly useful in exceptionally humid environments or climates, such as tropical rainforests or high-humidity seasons.

[0109] In this embodiment, by shortening the test distance between the substation and the test site under high humidity conditions, the adverse effects of humidity on electromagnetic testing can be effectively addressed, ensuring the accuracy and reliability of the test data.

[0110] In one exemplary embodiment, determining the influence adjustment coefficient of the electromagnetic probe based on ambient humidity includes:

[0111] Determine the mathematical model relating ambient humidity to the horizontal rotation rate of the electromagnetic probe;

[0112] Using a mathematical model, the influence adjustment coefficient of the electromagnetic probe is dynamically calculated based on the ambient humidity. The mathematical model includes the influence factors of ambient humidity on the propagation speed of electromagnetic waves and the influence factors on the sensitivity of the electromagnetic probe.

[0113] Specifically, it is used to describe the relationship between ambient humidity and the performance of electromagnetic probes (including horizontal rotation rate). The mathematical model typically includes multiple parameters and equations that reflect the specific impact of humidity on electromagnetic wave propagation speed and probe sensitivity.

[0114] Humidity can affect the speed at which electromagnetic waves propagate in the air; a propagation speed effect factor is used to quantify this effect. Humidity can also affect the sensitivity of the probe, i.e., the probe's ability to respond to changes in the electromagnetic field; a sensitivity effect factor is used to quantify this effect.

[0115] Using real-time monitored ambient humidity data, a mathematical model is used to dynamically calculate the adjustment coefficient. The calculated adjustment coefficient is then used to adjust the horizontal rotation rate of the electromagnetic probe to adapt to the current humidity conditions.

[0116] The model helps predict the performance changes of electromagnetic probes under different humidity conditions. By applying the model, test parameters can be optimized, improving the accuracy and efficiency of testing. Performance data of electromagnetic probes under different humidity conditions are collected for model building and validation. Algorithms are developed to calculate the mathematical model, enabling automatic calculation of adjustment coefficients. Experimental data is used to validate the accuracy of the mathematical model, ensuring it can reliably predict the impact of humidity on probe performance. The model is adjusted based on the validation results to improve its predictive accuracy. In actual testing, the probe's rotation rate is automatically adjusted according to humidity to maintain test accuracy.

[0117] In this embodiment, this method ensures that the electromagnetic probe maintains optimal performance under different humidity conditions, thereby improving the quality and reliability of electromagnetic environment testing.

[0118] In an exemplary embodiment, shortening the test distance between the substation and the test location when the ambient humidity is greater than a second preset humidity threshold includes:

[0119] The distance sensor is used to monitor the test distance between the substation and the test site in real time. When the ambient humidity is greater than the second preset humidity threshold, the test distance between the substation and the test site is shortened, and the pitch angle and power output of the electromagnetic probe are automatically adjusted according to the humidity change.

[0120] Specifically, a humidity sensor is used to monitor ambient humidity in real time to ensure timely response to humidity changes. A second preset humidity threshold is set; when the humidity exceeds this threshold, corresponding adjustment measures are initiated. A distance sensor is used to monitor the distance between the substation and the test location in real time. When the humidity exceeds the second preset humidity threshold, the test distance is automatically or manually shortened to reduce the impact of humidity on electromagnetic wave propagation. The pitch angle of the electromagnetic probe is automatically adjusted according to humidity changes to optimize the reception and transmission direction of electromagnetic waves. Adjusting the pitch angle improves signal reception quality and reduces signal attenuation caused by humidity. The power output of the electromagnetic probe is automatically adjusted according to changes in humidity and distance to ensure signal strength and coverage. In high humidity environments, increased power output may be necessary to compensate for signal attenuation and maintain test accuracy. An automated control system is developed to automatically adjust test parameters based on real-time monitored humidity and distance data. The system can provide real-time feedback on the adjustment results, ensuring that test parameters are always in optimal condition. This method is particularly useful when conducting electromagnetic tests outdoors or in environments with significant humidity variations. In situations requiring long-term monitoring of the electromagnetic environment, dynamically adjusting test parameters ensures the continuity and reliability of test data.

[0121] In this embodiment, these adjustments improve the accuracy of electromagnetic testing in high humidity environments. Automated adjustments reduce manual intervention and increase testing efficiency.
