Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of zero-value insulator identification, and in particular to a zero-value insulator identification method, a storage medium, an electronic device and a device applied to the method. BACKGROUND

[0002] For the detection and maintenance of power transmission lines, porcelain insulator strings need to be detected more efficiently. Traditional manual power-off contact detection is inefficient and poses a great safety risk to personnel during operation.

[0003] Zero-value insulator detection is one of the common tasks of power transmission line outage maintenance and live-line work. Current solutions include measuring the electric field at the symmetric points of the insulator string to determine whether the electric field is symmetrical to determine whether the double string contains zero-value insulators. However, if the two parallel symmetric insulators on the double string are both zero-value insulators, the measurement of the electric field by symmetry may result in a missed judgment. Moreover, this solution can only detect whether there are zero-value insulators, but cannot determine which string in the double string the zero-value insulator is located in, and still requires manual tower climbing detection to determine the specific location. At the same time, this solution measures zero-value insulators by the symmetry of the electric field distribution of the insulator string, which has a high requirement for the overall arrangement of the insulator string. In actual working conditions, the insulator string may be misaligned to some extent, which may change the electric field distribution of the insulator string. Therefore, when this solution is applied to zero-value insulator detection, the detection accuracy is difficult to guarantee, and the detection is relatively inconvenient.

[0004] Therefore, there is an urgent need for a solution to solve the problem of inconvenient zero-value insulator detection. SUMMARY

[0089] As attached Figure 6 As shown, the detection algorithm for slight misalignment is:

[0090] When there is a slight mismatch between the matching of strings A and B in this segment, the electric field moduli E1, E2, E3, and E4 are obtained through adjustable electric field probes a, b, c, and d, respectively. The average electric field strength at the locations of the adjustable electric field probes a, b, c, and d is then calculated. Define the local unilateral electric field distortion factor. , The closer a value is to 1, the smaller the degree of local unilateral electric field distortion. The local unilateral electric field distortion factors on two planes symmetrical above and below the planes containing strings A and B are respectively... And calculate their average value. = ; Calculate the degree of distortion | 1- |*z, where z is a preset scaling parameter, set to 10. 3 Preset unilateral electric field distortion threshold T If |1- |*10 3 > This means that there must be an insulator with a zero value on one and only one side of strings A and B. If |1-1|, it means that string A has a zero-value insulator; conversely, if |1-1|, it means that string B has a zero-value insulator. |*10 3 Then, the electric field moduli E5, E6, E7, and E8 are obtained through electric field probes e, f, g, and h, and the average electric field strength at the locations of electric field probes e and f is calculated. And the average electric field strength at the locations of electric field probes g and h. Preset mild zero value judgment threshold ,like If the value is zero, it means that both strings A and B have zero-value insulators; otherwise, neither strings A nor B have zero-value insulators.

[0091] As attached Figure 9 Appendix Figure 10 and attached Figure 11 As shown, in another specific embodiment, when the 15th insulator of string B is a zero-value insulator, the electric field mode distribution around the two parallel insulator strings A and B under an 800kV DC voltage is calculated for misalignment values ​​d of 0cm, 2.5cm, and 5cm. In this embodiment, through simulations under multiple misalignment value d conditions, the results are further summarized when a zero-value insulator appears in the 800kV parallel insulator strings, and a T value of 85 is determined to be suitable for 800kV double-string insulators. Table 2 gives the characteristic parameter values ​​for misalignment values ​​d of 0cm, 2.5cm, and 5cm.

[0092] Table 2 T-characteristic parameter values

[0093]

[0094] The selection principle for T is to be as close as possible to the lower limit of the electric field distortion around the zero-value insulator. Since the location selected in Table 2 is the position of the steel foot of the zero-value insulator, the electric field modulus around the zero-value insulator is the smallest at this location. Therefore, |1- |*10 3 The value of T is relatively large. Observing the electric field mode curve, it can be seen that the electric field has changed significantly in the neighborhood with a radius of 0.1m, reaching the conditions required for zero measurement. Considering the error between simulation and actual working conditions, and taking into account a certain margin, this embodiment selects the value of T as 85.

[0095] As attached Figure 12 Appendix Figure 13 and attached Figure 14As shown, in another embodiment, when the 15th insulator of the A string and the B string is a zero-value insulator, the overall electric field mode distribution around the two parallel insulator strings of the A string and the B string under 800 kV DC voltage is shown when the misalignment value d is 0 cm, 2.5 cm, and 5 cm, respectively. In this algorithm embodiment, through simulation under multiple misalignment value d conditions, further summary is made when the zero-value insulator appears in the 800 kV parallel insulator string, and the determination of the characteristic parameter value suitable for the 800 kV double-string insulator is proposed The value of the characteristic parameter is 4.5 kV / m. Table 3 shows the characteristic parameter values when the misalignment value d is 0 cm, 2.5 cm, and 5 cm, respectively.

[0096] Table 3 Characteristic parameter value

[0097]

[0098] The selection principle is to be as close as possible to the lower limit value of identifying the zero-value insulator. When the misalignment value d is larger, the electric field mode at the zero-value insulator is smaller, and the difference between the electric field mode around the adjacent insulators is also smaller. As shown in Table 2, when d = 5 cm, The minimum value is 5.79. As long as the zero-value insulator can be normally identified when the misalignment value d = 5 cm, the misalignment value d can be guaranteed to be less than 5.79. The zero-value insulator under the working condition can be identified, so the value is less than this value. In order to prevent misjudgment, considering the error between simulation and actual working condition and combining with a certain margin, the value of the misalignment value d in this embodiment is selected to be less than 5.79. The value of the characteristic parameter is 4.5 kV / m. Table 4 shows the results of the zero-value insulator detection verification of the algorithm.

[0100]

[0101] As shown in the accompanying drawings, Figure 7 The detection algorithm corresponding to the moderate misalignment is:

[0102] When the A string and the B string match the moderate misalignment, the electric field mode values E1, E2, E3, E4, and E0 are obtained by the adjustable electric field probe a, the adjustable electric field probe b, the adjustable electric field probe c, the adjustable electric field probe d, and the electric field probe o, respectively, and the field intensity average value of the A string and the field intensity average value of the B string are calculated.

[0103] The electric field mode values E5, E6, E7, and E8 are obtained by the electric field probe e, the electric field probe f, the electric field probe g, and the electric field probe h, respectively, and the moderate first zero-value judgment threshold value And determine whether it satisfies If satisfied, and Then, further determine whether it satisfies If the condition is met, then string A has zero-value insulators; if the condition is not met, then string A has no zero-value insulators.

[0104] If satisfied But not satisfied Then determine whether it satisfies If the condition is met, then string B has zero-value insulators; if the condition is not met, then string B has no zero-value insulators.

[0105] If not satisfied Then calculate the average electric field strength at the points where electric field probes e and f are located. And the average electric field strength at the locations of electric field probes g and h. Preset moderate second zero value judgment threshold And further determine, if the conditions are met , If the condition is met, then both string A and string B have zero-value insulators; if not, then neither string A nor string B has zero-value insulators.

[0106] As attached Figure 15 Appendix Figure 16 and attached Figure 17 As shown in another specific embodiment, when the 15th insulator of string B is a zero-value insulator, the overall distribution of the electric field mode around the parallel insulator strings of strings A and B under 800kV DC voltage is illustrated under the conditions of misalignment values ​​d of 6cm, 8cm, and 10cm. In this algorithm embodiment, through simulations under multiple misalignment value d conditions, the results are further summarized when a zero-value insulator appears in the 800kV parallel insulator strings, and a method suitable for 800kV double-string insulators is proposed. The value is taken as 3.5 kV / m. Table 5 gives the characteristic parameter values ​​for the misalignment values ​​d as 6 cm, 8 cm, and 10 cm.

When d=10cm, the insulators on the double string are in the case of symmetry between the steel foot and the steel cap. At this time, |E A -EB At the minimum, within this misalignment range, as long as the zero-value insulator can be correctly identified when the misalignment value d=10cm, the misalignment value can be guaranteed. Zero-value insulators under operating conditions can be identified, so the settings are... To prevent misjudgment, considering the errors between simulation and actual working conditions, and taking into account a certain margin, this embodiment selects a value smaller than this one.

[0117] When the matching of strings A and B in this segment is severely misaligned, the adjustable electric field probes a, b, c, and d are displaced and their spacing is automatically adjusted until the spacing between adjustable electric field probes a and c equals the misalignment value d, and the spacing between adjustable electric field probes b and d equals the misalignment value d. At this point, the extreme values ​​of the electric field modulus of adjustable electric field probes a, b, c, and d are E, respectively. 1,k E 2,k E 3,k and E 4,k And extract the extreme values ​​E of the electric field modulus of the adjustable electric field probes a, b, c, and d at the points in strings A and B above. 1,k-1 E 2,k-1 E 3,k-1 and E 4,k-1 The electric field probe o obtains the electric field modulus E0 for this segment;

If the value is zero, then the segment of string B has a zero value; otherwise, the segment of string B has no zero value.

[0120] As attached Figure 21 Appendix Figure 22 and attached Figure 23 As shown, in another specific embodiment, when the 12th insulator of string A and the 19th insulator of string B are both zero-value insulators, and the misalignment values ​​d are 10.5cm, 13cm, and 15cm respectively, the overall distribution of the electric field mode around the two parallel insulator strings A and B under 800kV DC voltage is illustrated. In this algorithm embodiment, through simulations under multiple misalignment value d conditions, the occurrence of zero-value insulators in 800kV parallel insulator strings is further summarized, and a method suitable for 800kV double-string insulators is proposed. The value is taken as 6kV / m. Table 8 gives the characteristic parameter values ​​for the misalignment values ​​d as 10.5cm, 13cm, and 15cm.
