Benefits of technology

This technology uses lighting data about an entire network's wires to detect any damage or other issues with it before they can cause problems such as power failures. It also analyzes how frequently there are damages made during normal operations to help identify possible causes early preventive measures against these types of events.

Problems solved by technology

This patented technical problem addressed in this patents relates to detecting electrical arcs caused during lightening events at high altitudes (lights) with sensors placed near the top surface of communication cables.

Embodiment Construction

[0040] The technical solution of the present invention will be described below in conjunction with the accompanying drawings.

[0041] Such as figure 1 As shown, it is a flow chart of the method for associating lightning data and transmission line body operation data in the present invention. The method comprises the steps of:

[0042] Step 1: Inject W, E, D, F component attributes.

[0043] Let W be the lightning set, E be the transmission line equipment set, D be the defect set, and F be the fault set. W and E can perform matching and connection operations through positional relationship. D, F and W can be matched and connected through the time relationship. D, F and E can be matched and connected through the positional relationship.

[0044] According to the needs of the analysis scale, each type of collection can include different quantities of specific components, for example: W can inject a series of lightning strike times and lightning current intensity vector valu...

Abstract

The invention provides a method of associating lightning data with operation data of a power transmission line. The comprises the following steps: step one, injecting W, E, D, F component attributes; step two, carrying out data connection and scalarization on lightning data based on a K-means method; step three, searching frequent items by using Apriori and finding out a result meeting a support degree and confidence; step four, setting a precondition lhs and a postcondition rhs and filtering the result; and step five, restoring the scalarization lightning data to obtain knowledge having guiding significance. According to the method provided by the invention, With the lightning data related with main faults, an association analysis is carried out based on a power transmission line as an element; and a frequent rule the influence on the power transmission line by the lightning force is discovered from lots of defect faults, so that the power transmission line is repaired in a targeted manner. Therefore, fault and defect occurrence is reduced and the reference basis is provided.
