[0023] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The technical solutions in the embodiments of the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0026] As described in the background section, high-voltage direct current (HVDC) grounding electrodes operate in a unipolar return configuration during operational faults or equipment maintenance. The current discharged into the ground in this configuration is in the thousands of amperes, causing changes in the nearby soil and creating a potential difference between different locations. This potential difference induces current in buried metal components, leading to corrosion of the buried metal structure. The degree of interference to pipelines caused by HVDC unipolar operation is related to the grounding electrode's discharge current, the unipolar operation time, soil environment, and pipeline parameters. Current research progress includes installing potential monitoring devices along the buried pipeline route to monitor potential shifts. However, based on the characteristics of high-voltage direct current interference, soil is also a major factor affecting the degree and range of interference. It is also necessary to monitor the soil ground potential gradient when the grounding electrode is running as a single electrode, and further establish the correlation between the ground current, the ground potential gradient, and the pipeline potential. Existing solutions often require manual testing due to the large distance between the two electrodes, resulting in low testing efficiency. To solve the problem that existing solutions cannot determine the possibility of current corrosion between the two electrodes, embodiments of this application provide a method, apparatus, computer-readable storage medium, electronic device, and system for determining the risk level of current corrosion between two electrodes.

[0030] In the embodiments, a method for determining the risk level of galvanic corrosion between two electrodes running on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0031] Figure 2 is a flowchart of a method for determining the risk level of galvanic corrosion between two electrodes according to the embodiments of the present application. As shown in Figure 2 the method includes the following steps:

[0032] In step S201, a plurality of test potentials are obtained, the plurality of test potentials are obtained by placing a plurality of test pieces between two electrodes, the test potential is the potential value of the test piece, the electrodes and the test pieces are respectively located in the soil, and the test pieces are located on the side close to the center of the earth of the electrodes;

[0033] Specifically, one of the two test pieces as end portions is taken as a reference test piece;

[0034] Step S202, according to all the above test potential, determine a plurality of target test pieces, a plurality of the above target test pieces are at least part of all test pieces;

[0035] Specifically, as shown in Figure 3 MMO group 1 and MMO group 2 are two electrodes respectively, test piece Z1 is a reference test piece, test piece Z2 and test piece Z4 are target test pieces, the efflux current between Z1 and Z2 is detected, and the efflux current between Z4 and Z5 is detected;

[0036] Step S202, comprising the following steps:

[0037] Determine that the test piece corresponding to the test potential greater than or equal to the predetermined potential in all the above test potential is the target test piece.

[0038] Specifically, for example, the test potential is 5, 6, 7, 8, 9 in turn, and the predetermined potential is 7.5, then the test pieces corresponding to 8 and 9 are target test pieces, by screening the target test pieces, the subsequent calculation amount is reduced, and the speed of subsequent determination of corrosion grade is improved.

[0039] Step S203, according to all the above target test pieces, determine the efflux current corresponding to each of the above target test pieces, the efflux current is the current flowing between two adjacent target test pieces;

[0040] Before step S203, that is, before determining the risk level of current corrosion of each target test piece according to all the above efflux currents, the method further comprises:

[0041] Obtain a first efflux current average, the first efflux current average is the average of all the above efflux currents;

[0042] Determine that the first efflux current average is the predetermined efflux current.

[0043] Specifically, for example, the efflux current is 10, 11, 12, 13, and 15 respectively, then 12.2 is the first efflux current average, and 12.2 is determined as the predetermined efflux current, which provides guarantee for the accuracy of subsequent determination of the risk level of current corrosion.

[0044] Before step S203, that is, before determining the risk level of current corrosion of each target test piece according to all the above efflux currents, the method further comprises: obtaining an efflux current median, the efflux current median is the median of all the above efflux currents; determine that the efflux current median is the predetermined efflux current.

[0045] Specifically, for example, the efflux currents are 11, 12, 13, 14, and 15, respectively, 13 is the first efflux current average, and 13 is determined as the predetermined efflux current, which guarantees the accuracy of the subsequent determination of the risk level of current corrosion.

[0046] Before step S203, that is, before the risk level of current corrosion of the position corresponding to each target test piece is determined according to all the efflux currents, the method further comprises:

[0047] The first efflux current is one of all the efflux currents, and the second efflux current is one of all the efflux currents; and a second efflux current average is obtained, which is the average of the first efflux current and the second efflux current.

[0048] The second efflux current average is determined as the predetermined efflux current.

[0049] Specifically, for example, the efflux currents are 11, 12, 13, 14, and 15, respectively, 13 is the first efflux current, 14 is the second efflux current, the second current average is 13.5, and 13.5 is determined as the predetermined efflux current, which guarantees the accuracy of the subsequent determination of the risk level of current corrosion.

[0050] Step S204, according to all the efflux currents, the risk level of current corrosion of the position corresponding to each target test piece is determined, the risk level of current corrosion is used to represent the possibility of current corrosion within a predetermined time period after the current time, in the case that the efflux current is greater than or equal to the predetermined efflux current, the risk level of current corrosion of the position corresponding to the target test piece is determined as the first risk level; in the case that the efflux current is less than the predetermined efflux current, the risk level of current corrosion of the position corresponding to the target test piece is determined as the second risk level, the possibility corresponding to the first risk level is greater than the possibility corresponding to the first risk level.

[0051] Specifically, the predetermined time period can be a time period starting from the determination of the risk level of current corrosion at the current time and stopping after half a day (i.e., 12 hours), and the risk level of current corrosion is determined by the greater the efflux current, the easier the soil is to corrode.

[0052] In an embodiment of the present application, the method further comprises: determining that the test piece corresponding to the test potential less than the predetermined potential is a discarded test piece, and the discarded test piece is the test piece not used to determine the efflux current.

[0053] Specifically, by selecting discarded test pieces, useless test pieces can be identified as early as possible, thus preventing discarded test pieces from affecting subsequent operations.

[0054] Through the above embodiments, by burying electrodes and test pieces in the soil respectively, the test potential corresponding to each test piece is obtained, and the target test piece can be selected. Based on all the above target test pieces, the outflow current corresponding to each target test piece is determined. Finally, the risk level of current corrosion is determined by the outflow current. This saves too much manpower and can achieve the purpose of determining the risk level of current corrosion between two electrodes, thereby solving the problem that the existing solution cannot determine the possibility of current corrosion between two electrodes.

[0055] By measuring the potential of each test piece, it can be determined that the test piece closer to the two poles has a higher potential, while the test piece farther away from the two poles has a lower potential. This indicates that the test piece closer to the two poles has a larger outflow current, while the test piece farther away from the two poles has a smaller outflow current.

[0056] To enable those skilled in the art to better understand the technical solution of this application, the implementation process of the method for determining the risk level of current corrosion between two electrodes in this application will be described in detail below with reference to specific embodiments.

[0057] This embodiment relates to a specific method for determining the risk level of current corrosion between two electrodes, including the following steps:

[0058] Step S1: As Figure 3 As shown, the first reference electrode was placed at position 1 of MIMO group, and the second reference electrode was moved gradually towards MIMO group 2 with MIMO group 1 (i.e., the positive ground electrode) as the center and a spacing of 1m. The range of change of ground potential gradient at different distances during the operation of the ground electrode single electrode was tested under different power supply output currents (0A to 2.5A).

[0059] Step S2: Connect a 100Ω resistor in series between Z1 and Z2, Z2 and Z3, Z3 and Z4, and Z4 and Z5 respectively. Test the voltage across the resistors between Z1 and Z2, Z2 and Z3, Z3 and Z4, and Z4 and Z5 under different output current conditions of the DC power supply, and then calculate the outflow current between different test pieces.

[0060] Step S3: Under the output current conditions of 0A, 0.5A, 1A, 1.5A, 2A and 2.5A, the ground potential gradient from 1m, 2m, 3m to 10m is shown in Table 1. By measuring the potential of each test piece, it can be seen that the potential of the test piece closer to the two poles is higher and the potential of the test piece farther away from the two poles is lower. Thus, it can be seen that the outflow current of the test piece closer to the two poles is larger and the outflow current of the test piece farther away from the two poles is smaller.

[0061] Table 1 Potential table for the range of 1 to 10m

[0062]

[0063] Step S4: Convert the ground potential in Table 1 into a ground potential gradient, such as... Figure 4 As shown, within the same distance range, the ground potential gradient exhibits a trend of first decreasing rapidly, then decreasing slowly, and finally stabilizing as the distance increases. Analysis of the ground potential gradient within different distance ranges reveals that the gradient is mostly concentrated very close to the grounding electrode. Under output current conditions of 0A, 0.5A, 1A, 1.5A, 2A, and 2.5A, the current distribution of the test pieces between Z1 and Z2 and between Z4 and Z5 is as follows: Figure 5 As shown, the outflow current between test pieces Z1 to Z2 and Z4 to Z5, which are close to the grounding electrode, is much greater than the outflow current of the test piece at the grounding electrode in the middle position.

[0064] Step S5: Based on all the aforementioned outflow currents, determine the risk level of current corrosion at the location corresponding to each of the aforementioned target test pieces. The risk level of current corrosion is used to characterize the probability of current corrosion occurring within a predetermined time period. If the predetermined time period is after the current moment, and the outflow current is greater than or equal to the predetermined outflow current, determine the risk level of current corrosion at the location corresponding to the aforementioned target test piece as a first risk level; if the outflow current is less than the predetermined outflow current, determine the risk level of current corrosion at the location corresponding to the aforementioned target test piece as a second risk level. The probability corresponding to the first risk level is greater than the probability corresponding to the first risk level.

[0065] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0066] This application also provides a device for determining the risk level of inter-electrode current corrosion. It should be noted that this device can be used to execute the method for determining the risk level of inter-electrode current corrosion provided in this application. This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.

[0067] The following describes the apparatus for determining the risk level of current corrosion between two electrodes provided in the embodiments of this application.

The electrodes and test pieces are located in the soil, with the test pieces positioned on the side of the electrodes closer to the Earth's center. The first determination unit 62 determines multiple target test pieces based on all the test potentials, where the multiple target test pieces are at least a portion of all the test pieces. The second determination unit 63 determines the outflow current corresponding to each target test piece based on all the target test pieces, where the outflow current is the sum of the potentials of two adjacent test pieces. The third determining unit 64 is used to determine the risk level of current corrosion at the location corresponding to each of the target test pieces based on all the aforementioned outflow currents. The risk level of current corrosion is used to characterize the probability of current corrosion occurring within a predetermined time period. The predetermined time period is after the current moment. If the outflow current is greater than or equal to the predetermined outflow current, the risk level of current corrosion at the location corresponding to the target test piece is determined to be a first risk level. If the outflow current is less than the predetermined outflow current, the risk level of current corrosion at the location corresponding to the target test piece is determined to be a second risk level. The probability corresponding to the first risk level is greater than the probability corresponding to the first risk level.

[0069] In the aforementioned device, electrodes and test pieces are buried in the soil to obtain the test potential corresponding to each test piece, thereby selecting the target test piece. Based on all the target test pieces, the outflow current corresponding to each target test piece is determined. Finally, the risk level of current corrosion is determined by the outflow current. This saves a lot of manpower and achieves the purpose of determining the risk level of current corrosion between two electrodes, thus solving the problem that existing solutions cannot determine the possibility of current corrosion between two electrodes.

[0073] In one embodiment of this application, the device further includes a third acquisition unit and a sixth determination unit.

[0074] In one embodiment of this application, the device further includes a fourth acquisition unit, a fifth acquisition unit, and a seventh determination unit. Before determining the risk level of current corrosion at the location corresponding to each of the aforementioned target test pieces based on all the aforementioned outflow currents, the fourth acquisition unit is used to acquire a first outflow current and a second outflow current, wherein the first outflow current is one of the aforementioned outflow currents, and the second outflow current is one of the aforementioned outflow currents; the fifth acquisition unit is used to acquire an average value of the second outflow current, wherein the average value of the second outflow current is the average of the first outflow current and the second outflow current; and the seventh determination unit is used to determine that the average value of the second outflow current is the predetermined outflow current.

[0075] The device for determining the risk level of current corrosion between the two electrodes includes a processor and a memory. The first acquisition unit, the first determination unit, the second determination unit, and the third determination unit are all stored as program units in the memory. The processor executes the program units stored in the memory to achieve the corresponding functions. All of the above modules are located in the same processor; or, the above modules are located in different processors in any combination.
