[0003] In related technologies, further analysis and judgment are made through the lightning data corresponding to the fault period, and positioning is often carried out with the help of drone inspection and ranging technologies. It is difficult to find faults one by one due to lightning strikes in the distribution network, and the accuracy of fault analysis and positioning is not high.

[0032] Method Embodiment

[0033] According to an embodiment of the present invention, a method for determining a lightning fault point is provided. Figure 1 is a flow chart of a method for determining a lightning fault point according to an embodiment of the present invention. Figure 1 As shown, the method for determining a lightning fault point according to an embodiment of the present invention specifically includes:

[0034] In step S110, the coordinates of each tower on the fault line are obtained, and the coordinates of the lightning strike point that coincides with the fault time are obtained, which specifically includes:

[0035] The coordinates of each tower on the fault line are collected in advance. For each lightning, the concentrated lightning fault point must be the position closest to the fault line. Therefore, it is only necessary to obtain the tower closest to the lightning strike position on the fault line. If the lightning strike time coincides with the fault line time, the location of the lightning fault point can be confirmed.

[0036] Obtain the fault type of the current fault, confirm the delay caused by the fault type, subtract the delay from the fault time to get the lightning strike moment, obtain the coordinates of the lightning strike point closest to the lightning strike moment as the coordinates of the lightning strike point that matches the fault time, and the subsequent lightning strike point coordinates are these coordinates;

[0037] The delay caused by different fault types is different. For example, fault A will occur about 1 minute after the lightning strike, and fault B will occur about 5 minutes after the lightning strike. The delay time is obtained based on past experience or data statistics. If fault B occurs at 10:10, the lightning strike time is about 10:05.

[0038] The coordinates of the tower and the lightning strike point are both achieved through the intelligent positioning technology GPS.

[0039] In step S120, the curvature radius is calculated according to the preset latitude value of the area to which the fault line belongs, and the distance change caused by unit latitude and the distance change caused by unit longitude are calculated according to the curvature radius, which specifically includes:

[0040] Since the distance between the lightning strike point and the tower is not very large, the error of the comprehensive lightning data is generally within 3 kilometers. The longitude and latitude of the coordinates of the two points are slightly different, and the curvature radius of the two points can be considered to be the same. Therefore, the preset latitude value in the area to which the fault line belongs is selected to represent the two points. Preferably, the preset latitude value can be the latitude value of the center point in the area;

[0041] The curvature radius of the weft coil is calculated according to Formula 1, and the curvature radius of the warp coil is calculated according to Formula 2:

[0042]

[0043]

[0044] Wherein, RW represents the curvature radius of the latitude circle, RJ represents the curvature radius of the meridian circle, B represents the preset latitude value, TANB represents the tangent value of the preset latitude, TANB=TAN(B / 180×π), a represents the major semi-axis of the earth ellipsoid, and b represents the minor semi-axis of the earth ellipsoid;

[0045] In the WGS84 coordinate system, the semi-major axis of the Earth's ellipsoid is approximately 6378137 meters, and the semi-minor axis of the Earth's ellipsoid is approximately 6356752 meters; Figure 2 Schematic diagram of the earth ellipsoid of the embodiment of the present invention, such as Figure 2 As shown, it shows the longitude lines distributed on the earth that intersect with the ground through lines parallel to the earth's axis, as well as the latitude lines formed by the intersection of all planes perpendicular to the earth's axis with the earth's surface.

[0046] The distance change caused by unit latitude is calculated according to formula 3, and the distance change caused by unit longitude is calculated according to formula 4:

[0050] In step S130, the north-south distance between each tower and the lightning strike point is calculated according to the coordinates of each tower, the coordinates of the lightning strike point and the distance change caused by the unit latitude; the east-west distance between each tower and the lightning strike point is calculated according to the coordinates of each tower, the coordinates of the lightning strike point and the distance change caused by the unit longitude; the straight-line distance between each tower and the lightning strike point is calculated according to the north-south distance and the east-west distance, specifically including:

[0051] Get the latitude values ​​of each tower coordinate and the latitude values ​​of the lightning strike point coordinate, combine the distance change caused by unit latitude, and use formula 5 to calculate the north-south distance:

[0052] SW1=(WD-WD1)×3600×KW Formula 5;

[0053] Among them, SW1 represents the north-south distance between the tower and the lightning strike point, WD represents the latitude value of the lightning strike point coordinates, and WD1 represents the latitude value of the tower coordinates;

[0054] Obtain the longitude values ​​of each tower coordinate and the longitude values ​​of the lightning strike point coordinate, and use Formula 6 to calculate the east-west distance based on the distance change caused by unit longitude:

[0055] SJ1=(JD-JD1)×3600×KJ Formula 6;

[0056] Among them, SJ1 represents the east-west distance between the tower and the lightning strike point, JD represents the longitude value of the lightning strike point coordinates, and JD1 represents the longitude value of the tower coordinates;

[0057] The difference multiplied by 3600 seconds means converting the longitude or latitude difference into seconds, and then multiplying it by the coefficient to calculate the east-west distance and the north-south distance;

[0058] Use Formula 7 to calculate the straight-line distance between each tower and the lightning strike point:

[0059]

[0060] Among them, S1 represents the straight-line distance between the tower and the lightning strike point.

[0061] In step S140, a calculation program is used to obtain a tower that is closest to the lightning strike point in a straight line as a faulty tower, and a detection tool is used to detect the lightning fault point within a threshold range of the faulty tower, specifically including:

[0062] A calculation program is used to cyclically poll and calculate the straight-line distance to the nearest tower. The detection tools used include but are not limited to fault indicator light equipment, smart sensors, drone inspections, infrared thermal imagers, etc. In the embodiment of the present invention, the threshold range refers to the area with the faulty tower as the center and the preset threshold as the radius.

[0063] To sum up, in response to the existing problems, the method for determining the lightning fault point of the present invention calculates the distance between the coordinates of each tower on the fault line and the lightning strike point, selects the nearest tower as the fault tower, and further detects the specific lightning fault point near the fault tower, first screens out a rough range and then performs precise detection, which improves the detection efficiency as a whole; when confirming the coordinates of the lightning strike point that coincides with the time, the delay corresponding to different fault types can be considered, and the lightning strike time can be determined more accurately; when calculating the distance, the curvature radius is calculated based on the earth ellipsoid theory, which improves the accuracy of the distance calculation, and the calculation of the curvature radius is based on the preset latitude value of the area to which the fault line belongs, which can eliminate the slight differences between the towers and the lightning strike points.
