Description

Technical Field

[0001] The present invention relates to the field of power detection technology, and in particular to a substation inspection method, device, equipment and storage medium. Background Art

[0002] With the continuous development and popularization of drone technology, drones are becoming increasingly widely used. In the power sector, they are often used to inspect transmission lines. However, due to the dense equipment density, complex electromagnetic environment, and high-criticality of substation equipment, the consequences of a voltage loss in substation equipment are relatively serious. Therefore, the use of drones in substation inspections is relatively risky, and the use of drones for substation equipment inspections is still a new field.

[0003] Due to the complex electromagnetic environment in substations, if drones are needed to inspect them, they must have strong anti-interference capabilities. In addition, the navigation methods used by drones, such as magnetic compass navigation, are more susceptible to magnetic field interference, and need to be avoided by methods such as visual navigation, Beidou navigation, and dual-antenna directionality. Therefore, if the drone's anti-interference capability is insufficient, it will seriously affect the safety of the equipment in the substation during its inspection. Summary of the Invention

[0061] Example 1

[0062] Figure 1 A flowchart of a substation inspection method provided in Example 1 of the present invention is applicable to the situation where a suitable drone is selected to inspect the substation to be inspected. The method can be executed by a substation inspection device, which can be implemented by software and / or hardware. The substation inspection device can be configured on a computer device, which can be a notebook, desktop computer, smart tablet, etc.

[0063] like Figure 1 As shown, the first embodiment provides a substation inspection method, which specifically includes the following steps:

[0064] S101. Obtain a power frequency electromagnetic field strength set corresponding to the substation to be inspected.

[0065] In this embodiment, the substation to be inspected can be specifically understood as a substation that requires inspection to determine the operational status of its equipment. The power-frequency electromagnetic field strength set can be specifically understood as the set of power-frequency electric field strength and power-frequency magnetic field strength at different locations within the substation to be inspected. Power-frequency electric field strength refers to the strength of the electric field generated by a charge that varies sinusoidally with time at 50 Hz or 60 Hz. Power-frequency magnetic field strength can be specifically understood as the magnetic field strength generated by AC power transmission and transformation facilities.

[0066] Specifically, when the substation to be inspected needs to be inspected, the power frequency electric field strength and power frequency magnetic field strength of different locations in the substation to be inspected and the areas that need to be highly concerned during the inspection are obtained, and the set of each power frequency electric field strength and each power frequency magnetic field strength is determined as the power frequency electromagnetic field strength set corresponding to the substation to be inspected.

[0067] In an embodiment of the present invention, by obtaining multiple power frequency electromagnetic field strengths at different locations in the substation to be inspected, the results obtained after performing anti-interference tests based on the above power frequency electromagnetic field strengths are more accurate and can cover the entire range of the substation to be inspected, thereby improving the safety and accuracy of subsequent inspections.

[0068] S102. Adjust the test parameters in the test area according to the power frequency electromagnetic field strength set, and perform anti-interference tests on at least three candidate drones according to the test parameters.

[0069] In this embodiment, the test area can be specifically understood as the area designated for testing candidate drones. The test parameters can be specifically understood as the parameters used to adjust the electric or magnetic field strength within the test area. The candidate drones can be specifically understood as drones of different brands, hardware, or models that can be used for substation inspections. The anti-interference test can be specifically understood as a test used to determine how the drone's operating state is affected by the electromagnetic field in its location.

[0070] Specifically, the test parameters in the test area are adjusted to the power frequency electric field intensity and power frequency magnetic field intensity in the power frequency electromagnetic field intensity set in turn, and each alternative UAV is controlled to hover in the test area under each power frequency electric field intensity and each power frequency magnetic field intensity to perform anti-interference test, and the anti-interference test results of each alternative UAV under each test parameter are obtained.

[0071] S103. Determine the safe power frequency magnetic field strength and safe power frequency electric field strength corresponding to each candidate UAV based on the anti-interference test results corresponding to each candidate UAV.

[0072] In this embodiment, the safe power frequency magnetic field strength can be specifically understood as the maximum magnetic field strength that will not affect the working state of the alternative drone. The safe power frequency electric field strength can be specifically understood as the maximum electric field strength that will not affect the working state of the alternative drone.

[0073] Specifically, for the multiple anti-interference test results corresponding to each alternative UAV, the test parameters corresponding to the anti-interference test results with successful test results are determined, and the maximum power frequency electric field strength and power frequency magnetic field strength are selected from each test parameter. The power frequency electric field strength is determined as the safe power frequency electric field strength corresponding to the alternative UAV, and the power frequency magnetic field strength is determined as the safe power frequency magnetic field strength corresponding to the alternative UAV.

[0074] S104. Determine a target drone from among the candidate drones based on the set of safety power frequency magnetic field intensities, safety power frequency electric field intensities, and power frequency electromagnetic field intensities, so as to inspect the substation to be inspected by the target drone.

[0075] In this embodiment, the target drone can be specifically understood as a drone among the candidate drones that meets the conditions of inspecting the substation to be inspected that currently needs to be inspected without being disturbed by the electromagnetic field in the substation to be inspected, which affects the working status.

[0076] Specifically, the maximum power frequency electric field intensity and power frequency magnetic field intensity are determined from the power frequency electromagnetic field intensity set, which indicates that the drone will be subjected to the maximum electromagnetic field interference during the inspection of the substation to be inspected. Then, an alternative drone whose safe power frequency magnetic field intensity is greater than the maximum power frequency magnetic field intensity and whose safe power frequency electric field intensity is greater than the maximum power frequency electric field intensity is determined from each alternative drone. It is used as the target drone. It can be considered that the anti-interference ability of the target drone is sufficient to support its inspection of the substation to be inspected without affecting its working status. Then, the determined target drone is used to inspect the substation to be inspected along a predetermined inspection route.

[0077] The technical solution of this embodiment is to obtain a power frequency electromagnetic field strength set corresponding to the substation to be inspected; adjust the test parameters in the test area according to the power frequency electromagnetic field strength set, and perform anti-interference tests on at least three alternative drones according to the test parameters; determine the safe power frequency magnetic field strength and safe power frequency electric field strength corresponding to each alternative drone based on the anti-interference test results corresponding to each alternative drone; determine the target drone from each alternative drone based on the safe power frequency magnetic field strength, the safe power frequency electric field strength and the power frequency electromagnetic field strength set, so as to inspect the substation to be inspected through the target drone. By adopting the above technical solution, when it is necessary to inspect the substation with inspection, the electromagnetic field strength in the test area is adjusted according to the power frequency electromagnetic field strength at different positions in the substation with inspection, and anti-interference tests on multiple alternative drones are completed in the test area. According to the anti-interference test results of each alternative drone, the safe power frequency magnetic field strength and safe power frequency electric field strength of different alternative drones are determined. Then, according to each safe power frequency magnetic field strength and each safe power frequency electric field strength, a target drone that is suitable for inspecting the substation to be inspected is selected, and the substation to be inspected is inspected by the target drone, which solves the problem that the substation cannot be inspected by drone due to the complex electromagnetic environment in the substation. According to the electromagnetic field strength of the substation to be inspected itself, a drone with anti-interference performance that meets its needs is selected, and it is inspected by the drone, thereby improving the inspection efficiency of the substation while ensuring the safe operation of the substation equipment.

[0078] Example 2

[0079] Figure 2 A flowchart of a substation inspection method provided in the second embodiment of the present invention is provided. The technical solution of the embodiment of the present invention is further optimized on the basis of the above-mentioned optional technical solutions. By obtaining the power frequency electric field strength and power frequency magnetic field strength corresponding to different preset measuring point positions in the substation to be inspected, and setting them in the test area as test parameters, each candidate drone can determine the corresponding test working state for each different test parameter in the test area, and then determine the anti-interference test result of the candidate drone based on the test working state, and determine the safe power frequency electric field strength and safe power frequency magnetic field strength corresponding to each candidate drone based on the anti-interference test result, and determine the candidate drone with a safe power frequency magnetic field strength greater than or equal to the maximum power frequency magnetic field strength and a safe power frequency electric field strength greater than or equal to the maximum power frequency electric field strength as the target drone. By selecting a drone with anti-interference capability that meets the requirements of the substation to be inspected, the substation is inspected without human intervention, and the drone is not likely to fall due to electromagnetic interference, thereby affecting the safety of the substation equipment. While ensuring the safe operation of the substation equipment, the inspection efficiency of the substation is improved.

[0080] like Figure 2As shown, a substation inspection method provided by the second embodiment of the present invention specifically includes the following steps:

[0081] S201. Obtain the power frequency electric field strength and power frequency magnetic field strength corresponding to different preset measuring points in the substation to be inspected.

[0082] The preset measuring point locations are electromagnetically sensitive locations in the substation to be inspected, including at least a main transformer, a reactor and a substation inspection walkway.

[0083] Specifically, when it is necessary to inspect the equipment in the substation to be inspected, measuring points are set at locations in the substation to be inspected where large electromagnetic fluctuations may occur, as well as at electromagnetic sensitive locations, and the power frequency electric field strength and power frequency magnetic field strength corresponding to the measuring point locations are collected at the corresponding measuring points.

[0084] For example, when measuring the power frequency magnetic field, the power frequency magnetic field meter can be set up at a distance of 1-2 meters from the ground, such as 1.5 meters; the measuring probe can be supported by a small dielectric handle and held by the measuring personnel; the preset measuring point location can be other electromagnetic sensitive locations such as the substation patrol walkway, control building, etc. When measuring the power frequency magnetic field strength near the main transformer and reactor by the measuring probe, the measuring probe can be set at a distance of 1 meter from the main transformer and reactor casing or fence boundary; at a specific time, place and meteorological conditions, if the reading of the power frequency magnetic field meter is stable, the power frequency magnetic field strength is the reading of the power frequency magnetic field meter when the measurement reading is stable; if the reading of the power frequency magnetic field meter fluctuates, fixed interval readings are used, and the average value of each reading is determined as the power frequency magnetic field strength corresponding to the measuring point location.

[0085] Continuing with the above example, when measuring the power frequency electric field, the power frequency electric field meter can be set up at a distance of 1-2 meters from the ground, such as 1.5 meters. The measurement personnel should be far enough away from the probe of the power frequency electric field meter, generally at least 2.5 meters, to avoid large electric field distortion at the power frequency electric field meter. The distance between the power frequency electric field meter and fixed objects should be no less than 1 meter to limit the influence of fixed objects on the measured values ​​of the power frequency electric field meter to an acceptable level. The preset measurement point location can be other electromagnetic sensitive areas such as the substation patrol corridor, control building, etc. Sensing position, when measuring the power frequency electric field strength near the main transformer and reactor through the measuring probe, the measuring probe should be 2.5m away from the casing of the main transformer or the fence boundary, and the maximum value of the field strength near the main transformer should be measured; under specific time, place and meteorological conditions, if the reading of the power frequency electric field meter is stable, the power frequency electric field strength is the reading of the power frequency electric field meter when the measurement reading is stable; if the reading of the power frequency electric field meter fluctuates, take fixed interval readings, and determine the average value of each reading as the power frequency electric field strength corresponding to the measuring point.

[0086] S202: Determine a set of the power frequency electric field intensities and the power frequency magnetic field intensities as a power frequency electromagnetic field strength set.

[0087] S203. During an anti-interference test of an alternative UAV, test parameters within the test area are sequentially set to parameter values ​​corresponding to each power-frequency magnetic field strength or each power-frequency electric field strength in the power-frequency electromagnetic field strength set.

[0088] Specifically, in the process of conducting anti-interference tests on each candidate UAV, each time an anti-interference test is conducted, the test parameters in the test area are adjusted once, and according to the power frequency electric field strength and power frequency magnetic field strength included in the power frequency electromagnetic field strength set, the parameter values ​​in the test equipment that generates electric fields or magnetic fields in the test area are adjusted so that the electric field strength in the test area is equal to the power frequency electric field strength, or the magnetic field strength in the test area is equal to the power frequency magnetic field strength.

[0089] For example, when the basis for adjusting the test parameters in the test area is the industrial frequency magnetic field strength, the test equipment in the test area can be a current-carrying coil arranged in the center of the test area. Assuming that the industrial frequency magnetic field strength targeted by the device selection drone during the current anti-interference test is B1, the current I1 that needs to pass through the current-carrying coil can be determined based on the correspondence between the industrial frequency magnetic field strength and the industrial frequency current. This current is the test parameter corresponding to the industrial frequency magnetic field strength B1.

[0090] Continuing with the above example, when the basis for adjusting the test parameters in the test area is the power frequency electric field strength, the test equipment in the test area can be a parallel plate set in the center of the test area. Assuming that the power frequency electric field strength targeted by the device selection drone during the current anti-interference test is E1, the voltage U1 that should be applied to both ends of the parallel plate can be determined based on the corresponding relationship between the power frequency electric field strength and the power frequency voltage. This voltage is the test parameter corresponding to the power frequency electric field strength E1.

[0091] S204. Determine the test power frequency magnetic field strength or the test power frequency electric field strength corresponding to the test area under the test parameters, and determine the field strength deviation between the test power frequency magnetic field strength and the corresponding power frequency magnetic field strength, or between the test power frequency electric field strength and the corresponding power frequency electric field strength.

[0092] In this embodiment, the power frequency magnetic field strength test can be specifically understood as the magnetic field strength within the test area; the power frequency electric field strength test can be specifically understood as the electric field strength within the test area. The field strength deviation can be specifically understood as the difference between the power frequency magnetic field strength test and the corresponding power frequency magnetic field strength, or the difference between the power frequency electric field strength test and the corresponding power frequency electric field strength.

[0093] Specifically, when the anti-interference test is a test for the power frequency magnetic field strength, before the test, the probe of the power frequency magnetic field measuring instrument is placed in the center of the corresponding test equipment structure in the test area, the collected magnetic field strength is determined as the test power frequency magnetic field strength in the test area, and the difference between the test power frequency magnetic field strength and the power frequency magnetic field strength corresponding to the test parameters is determined as the field strength deviation; when the anti-interference test is a test for the power frequency electric field strength, before the test, the probe of the power frequency electric field measuring instrument is placed in the center of the corresponding test equipment structure in the test area, the collected electric field strength is determined as the test power frequency electric field strength in the test area, and the difference between the test power frequency electric field strength and the power frequency electric field strength corresponding to the test parameters is determined as the field strength deviation.

[0094] S205 , determining whether the field intensity deviation is within a preset field intensity deviation threshold; if so, executing step S207 ; if not, executing step S206 .

[0095] In this embodiment, the preset field strength deviation threshold can be understood as a threshold range used to determine whether the field strength within the test area meets the field strength requirements for anti-interference testing of candidate drones. For example, the field strength deviation threshold can be ±5% of the corresponding field strength, and can also be set based on actual circumstances. This embodiment of the present invention is not limited to this.

[0096] Specifically, by judging whether the field strength deviation is within the preset field strength deviation threshold, if so, it can be considered that the test power frequency magnetic field intensity or the test power frequency electric field intensity in the test area is similar to the power frequency magnetic field intensity or the power frequency electric field intensity required to test the alternative UAV, and can be used to perform anti-interference test on the alternative UAV, and step S207 is executed at this time; if not, it can be considered that the test power frequency magnetic field intensity or the test power frequency electric field intensity in the test area is quite different from the power frequency magnetic field intensity or the power frequency electric field intensity required to test the alternative UAV, and the accuracy of the anti-interference test result performed using it is low, and the magnetic field intensity or electric field intensity in the test area needs to be adjusted to meet the test requirements, and step S206 is executed at this time.

[0097] S206: Adjust the test parameters corresponding to the field intensity deviation, and return to step S204.

[0098] Specifically, the adjustment direction of the field strength in the test area is determined according to the field strength deviation, and the adjustment parameters used to adjust the test parameters are determined according to the correspondence between the power frequency magnetic field strength and the power frequency current, or according to the correspondence between the power frequency electric field strength and the power frequency voltage. The test parameters are adjusted by the adjustment parameters, and the corresponding magnetic field or electric field is generated in the test area according to the adjusted test parameters, and the process returns to step S204 to determine whether the corresponding field strength deviation meets the anti-interference test conditions for the alternative UAV.

[0099] S207: Determine that the test parameter settings are complete.

[0100] S208: Obtain the initial working status of the candidate UAV.

[0101] Among them, the initial working state includes the initial minimum number of satellites, the initial compass state, the initial real-time dynamic signal state and the initial positioning state.

[0102] In this embodiment, the initial operating state can be specifically understood as the operating state of the alternative drone when it is not interfered with by the electromagnetic field. The initial minimum number of satellites can be specifically understood as the minimum number of satellites whose signals can be received by the satellite signal receiving device installed on the alternative drone when it is not interfered with by the electromagnetic field. The initial compass state can be specifically understood as the pointing state of the compass installed on the alternative drone when it is not interfered with by the electromagnetic field. The initial real-time dynamic signal state can be specifically understood as the state of the alternative drone performing real-time dynamic positioning (RTK) based on real-time differential GPS measurement technology when it is not interfered with by the electromagnetic field. The initial positioning state can be specifically understood as the state of the alternative drone acquiring GPS signals when it is not interfered with by the electromagnetic field.

[0103] Specifically, before each anti-interference test is performed on an alternative UAV, the minimum initial number of satellites, initial compass status, initial real-time dynamic signal status, and initial positioning status of the corresponding device in the alternative UAV are obtained to determine whether the alternative UAV can undergo anti-interference testing.

[0104] It should be made clear that before each anti-interference test, the initial working state of the corresponding candidate UAV must be obtained, and whether its initial working state meets the preset working conditions must be determined.

[0105] S209: Determine the test readiness state of the candidate UAV based on the initial working state and the preset working conditions.

[0106] In this embodiment, the preset operating conditions can be specifically understood as conditions for determining whether the candidate drone can perform inspections without interference. For example, the preset operating conditions can include the minimum number of satellites being greater than a preset number of satellites, the compass status being normal, the real-time dynamic signal status being normal, and the positioning status being normal.

[0107] Specifically, by judging whether the initial working state of the alternative UAV meets the preset working conditions, the test preparation state of the alternative UAV can be determined. When the initial working state meets the preset working conditions, the test preparation state of the alternative UAV is determined to be ready. When any item in the initial working state does not meet the preset working conditions, the test preparation state of the alternative UAV is determined to be incomplete.

[0108] That is, if the minimum value of the initial number of satellites is greater than the preset number of satellites, the initial compass state is normal, the initial real-time dynamic signal state is normal, and the initial positioning state is normal, then the test preparation state is determined to be ready; if the minimum value of the initial number of satellites is less than or equal to the preset number of satellites, the initial compass state is abnormal, the initial real-time dynamic signal state is abnormal, and / or the initial positioning state is abnormal, then the test preparation state of the alternative UAV is determined to be incomplete.

[0109] S210: Determine the candidate UAV whose test preparation status is "ready completed" as the target candidate UAV that needs to undergo anti-interference testing.

[0110] Specifically, since the anti-interference test for the UAV needs to ensure that the UAV can work normally in the absence of electromagnetic field interference, in order to avoid affecting the accuracy of the anti-interference test results due to the UAV's own reasons, when the test preparation status of the alternative UAV is ready, it can be considered that the current working status of the UAV can support it to perform normal inspection tasks. At this time, the alternative UAV can be used as the target alternative UAV that needs to undergo anti-interference testing.

[0111] S211 is to conduct an anti-interference test on a candidate target UAV under a test parameter, controlling the candidate target UAV to hover in the center of the test area after the test parameter setting is completed.

[0112] Specifically, for the anti-interference test of each target candidate UAV under each test parameter, the target candidate UAV can be allowed to fly into the test power frequency magnetic field or test power frequency electric field generated according to the set test parameters in the test area by importing the route into the target candidate UAV. At the same time, the target candidate UAV can be made to hover stably after flying to the center of the test area to simulate the influence of the electromagnetic field in the substation on the target candidate UAV during the inspection process in the substation.

[0113] S212: Obtain the test working status of the target candidate UAV.

[0114] Among them, the test working status includes testing the minimum number of satellites, testing the compass status, testing the real-time dynamic signal and testing the positioning status.

[0115] In this embodiment, the test working state can be specifically understood as the working state of the candidate UAV when it is hovering in the center of the test area and is affected by the electromagnetic field in the test area.

[0116] Specifically, during each anti-interference test for each target candidate UAV, the minimum number of test satellites, test compass status, test real-time dynamic signal and test positioning status of the corresponding device in the target candidate UAV are obtained after the UAV hovers in the center of the test area, so as to clarify whether the target candidate UAV can work normally under the influence of the electromagnetic field in the test area.

[0117] S213. Determine an anti-interference test result of the target candidate UAV under the test parameters according to the test working status and preset working conditions.

[0118] It should be made clear that the preset working conditions used to determine whether the drone can operate normally in the absence of interference and in the presence of interference should be the same to ensure the consistency of anti-interference test standards and improve test accuracy.

[0119] Specifically, by determining whether the target candidate drone's test operating status meets the preset operating conditions, the anti-interference test result of the target candidate drone under the corresponding test parameters can be determined. When the test operating status meets the preset operating conditions, it can be considered that the target candidate drone can normally perform the inspection task under the electromagnetic field corresponding to the test parameters. In this case, the anti-interference test result corresponding to the test parameters is determined to be successful. When the test operating status does not meet the preset operating conditions, it can be considered that the target candidate drone cannot normally perform the inspection task under the electromagnetic field corresponding to the test parameters, and may cause damage to the substation equipment along its inspection route. In this case, the anti-interference test result corresponding to the test parameters is determined to be a failure.

[0120] That is, if the minimum number of test satellites is greater than the preset number of satellites, the test compass status is normal, the test real-time dynamic signal status is normal, and the test positioning status is normal, the anti-interference test result is determined to be successful; otherwise, the anti-interference test result is determined to be a failure.

[0121] S214. For a candidate UAV, determine at least one power frequency magnetic field strength and at least one power frequency electric field strength corresponding to each anti-interference test result indicating a successful anti-interference test result.

[0122] Specifically, since multiple anti-interference tests are conducted on a candidate drone and multiple anti-interference test results are obtained, the test parameters corresponding to successful anti-interference test results are determined. Furthermore, based on the test parameters, the corresponding power frequency electric field strength and power frequency magnetic field strength in the substation are determined for each successful anti-interference test result. It should be clarified that each successful anti-interference test result must include at least one test under a magnetic field and one test under an electric field.

[0123] S215. Determine the maximum value among the power frequency magnetic field intensities as the safe power frequency magnetic field intensity corresponding to the candidate UAV.

[0124] S216. Determine the maximum value among the power frequency electric field intensities as the safe power frequency electric field intensity corresponding to the candidate UAV.

[0125] S217. Determine the maximum power frequency magnetic field intensity and the maximum power frequency electric field intensity corresponding to the substation to be inspected based on the power frequency electromagnetic field intensity set.

[0126] Specifically, the maximum power frequency magnetic field strength among the power frequency magnetic field strengths in the power frequency electromagnetic field strength set is determined as the maximum power frequency magnetic field strength corresponding to the substation to be inspected; the maximum power frequency electric field strength among the power frequency electric field strengths in the power frequency electromagnetic field strength set is determined as the maximum power frequency electric field strength corresponding to the substation to be inspected.

[0127] S218. Determine as a target drone a candidate UAV whose safe power frequency magnetic field strength is greater than or equal to the maximum power frequency magnetic field strength and whose safe power frequency electric field strength is greater than or equal to the maximum power frequency electric field strength.

[0128] Specifically, when the safety power frequency magnetic field strength is greater than or equal to the maximum power frequency magnetic field strength, and the safety power frequency electric field strength is greater than or equal to the maximum power frequency electric field strength, it can be considered that the alternative drone corresponding to the above parameters can still perform the inspection task normally even in the place with the largest electromagnetic interference in the substation to be inspected. At this time, the alternative drone corresponding to the above parameters is determined as the target drone that can be used to inspect the substation to be inspected.

[0129] S219. Use the target drone to inspect the substation to be inspected.

[0130] Optionally, embodiments of the present invention also provide another method for inspecting the substation to be inspected by selecting a target drone from candidate drones based on a set of safe power frequency magnetic field intensities, safe power frequency electric field intensities, and power frequency electromagnetic field intensities. The maximum power frequency electric field intensities and maximum power frequency magnetic field intensities for different inspection areas within the substation to be inspected can be determined based on the power frequency electromagnetic field intensities. For each inspection area, candidate drones are identified whose safe power frequency magnetic field intensities are greater than or equal to the maximum power frequency magnetic field intensities and whose safe power frequency electric field intensities are greater than or equal to the maximum power frequency electric field intensities. These candidate drones are then designated as target drones for inspecting the inspection area. After determining target drones for all inspection areas, the corresponding inspection areas within the substation to be inspected are inspected using the selected target drones. When planning the route, it is considered that the target drone's flight path should not include inspection areas with intensities greater than its safe power frequency magnetic field intensities and safe power frequency electric field intensities.

[0131] The technical solution of this embodiment obtains the power frequency electric field strength and power frequency magnetic field strength corresponding to different preset measuring point positions in the substation to be inspected, and sets them as test parameters in the test area in sequence, so that each alternative drone can determine the corresponding test working state for each different test parameter in the test area, and then determine the anti-interference test result of the alternative drone based on the test working state, and determine the safe power frequency electric field strength and safe power frequency magnetic field strength corresponding to each alternative drone based on the anti-interference test result, and determine the alternative drone whose safe power frequency magnetic field strength is greater than or equal to the maximum power frequency magnetic field strength and whose safe power frequency electric field strength is greater than or equal to the maximum power frequency electric field strength as the target drone. By selecting a drone whose anti-interference capability meets the requirements of the substation to be inspected, the substation is inspected without human participation, and the drone is not likely to fall due to electromagnetic interference, thereby affecting the safety of the substation equipment. While ensuring the safe operation of the substation equipment, the inspection efficiency of the substation is improved.
