A troubleshooting method for overhead transmission lines based on fault modes and fault trees

Abstract

The invention provides a method for overhauling the fault of an overhead transmission line built on the basis of a fault mode and a fault tree. The method comprises the following steps of: (1) knowing the system structure of the overhead transmission line, and formulating a fault mode analysis table of the overhead transmission line; (2) building an overhead transmission line fault tree analysis model according to the fault mode analysis table; (3) quickly finding out the fault happening mode and the fault happening reason according to the overhead transmission line fault tree analysis model built in the step (2) when the fault of the overhead transmission line is observed by the line patrol of professional persons and observed by an on-line monitoring device; (4) finding out the fault mode analysis table built in the step (1) according to an output result of the fault mode analyzed and obtained according to the overhead transmission line fault tree analysis model, and formulating a fault overhaul strategy; and (5) formulating an overhead transmission line fault overhaul form according to the fault overhaul strategy. After the method provided by the invention is used, the overhead transmission line fault mode analysis table and the fault tree analysis model are built, so that the specific parts where the fault happens can be quickly positioned when equipment breaks down, the fault reason can be found out, and the overhaul strategy can be formulated comprehensively and quickly.

Description

technical field [0001] The invention relates to the field of maintenance of power transmission and transformation equipment, in particular to a method for troubleshooting overhead transmission lines based on fault modes and fault trees, and belongs to the transformation technology of the method for troubleshooting overhead transmission lines based on fault modes and fault trees. Background technique [0002] Overhead transmission lines are an important part of the power system and the lifeblood of the power transmission system. Its main function is to transmit electrical energy. The operating status of overhead transmission lines has a direct and huge impact on the reliability of the entire system. At present, the national economy is developing at a high speed, and the scale of the power grid has been greatly expanded accordingly. However, due to the natural environment, external force damage, production quality and human factors, a large number of faults such as overhead t...

At present, the national economy is developing at a high speed, and the scale of the power grid has been greatly expanded accordingly. However, due to the natural environment, external force damage, production quality and human factors, a large number of faults such as overhead transmission lines have been caused. These faults will not only affect The transmission capacity of overhead transmission lines may also cause large-scale power outages, which will seriously affect the development of the national economy
