Embodiment Construction

[0025] Below, the embodiments of the present invention will be further described in conjunction with the accompanying drawings.

[0026] Such as figure 1 As shown, in the implementation of the technical solution proposed by the present invention, for a certain transmission line lightning tripping fault that has occurred, based on the transmission line data provided by the operating unit, the line tripping fault data and the line obtained by using the lightning location system query Corridor lightning activity information, and use lightning protection simulation analysis program, through computer analysis, use the collected and processed data to simulate and restore the faulty tower of the line that has tripped by lightning, compare and analyze, and obtain the discrimination result. Specifically, the following steps are adopted:

[0027] (1) Use computer to collect and organize transmission line information (transmission line data and line trip fault data)

[0028] Given the t...

Abstract

The invention relates to a method for judging the failure properties of shielding failure and counterattack of a transmission line. In the method, a computer is adopted to collect and process data; and for a certain lightning tripping failure of the transmission line, a lightning protection simulation analysis program is adopted and the collected and processed data is applied by the analysis of the computer to perform simulation reduction and comparison analysis on a circuit-failing tower with the lightning tripping to obtain a judgment result based on the data of the transmission line provided by a running unit, circuit tripping failure data and the lightning activity information of a line corridor obtained by the query of a lightning positioning system. The method comprises the following basic steps of: (1) performing collection and clearing-up on the data of the transmission line and the circuit tripping failure data by adopting the computer; (2) querying the lightning activity information in the corridor of the failing tower by utilizing the lightning positioning system; (3) analyzing the lightning protection performance of the failing tower by the computer by utilizing the lightning protection simulation analysis program; and (4) checking the lightning protection performance and judging the failure property. The method is simple, convenient and easy to operate and convenient to popularize and apply, and ensures low cost.

Description

technical field [0001] The invention relates to the field of electric network lightning protection, in particular to a method for judging the nature of shielding and counterattack faults of transmission lines, which is suitable for judging whether the tripping fault caused by lightning strikes on the transmission line is shielding or counterattack. Background technique [0002] At present, power grid lightning accidents are becoming more and more serious, directly affecting the safe and stable operation of the power grid and the reliability of power supply and consumption. Identifying the nature of lightning strike faults on existing transmission lines and analyzing the specific causes of lightning strike trips are important references for guiding the lightning protection transformation of power grids. [0003] As far as the applicant knows, the current identification of the nature of lightning trip faults on transmission lines mainly includes the magnetic steel rod method a...
