Method for drawing degree distribution map of common damage to power transmission line

Abstract

The invention discloses a method for drawing a degree distribution map of common damage to a power transmission line. The method comprises a step 1 of screening common damage types; a step 2 of acquiring common damage risk map data; a step 3 of re-grading the risks of the screened common damage types; a step 4 of computing the average weighted value of damage data; a step 5 of making a re-grading damage risk map overlay analysis rule; a step 6 of preprocessing the damage risk maps according to the rule; a step 7 of performing overlay analysis on the damage risk maps; and a step 8 of generating an average damage degree distribution map. The method solves a technical problem that a power transmission line operation and maintenance strategy in the prior art cannot overall consider and fully utilize the damage to a power transmission line when established, and cannot really reflect the key points of a power transmission line operation and maintenance area or provide reliable support service for operation and maintenance periods.

Description

Technical field: [0001] The invention belongs to the prevention and control technology of disaster hazards of transmission lines, and in particular relates to a method for drawing a distribution map of common disaster hazards of transmission lines. Background technique: [0002] Since the reform and opening up, my country's economy has continued to develop at a high speed, and the stable development of the power system has provided a strong development momentum for the country and society. At the same time, the power system is increasingly facing internal and external high-risk or emergencies. If a large-scale power outage is caused, it is very likely to lead to a major disaster in modern society and cause various secondary disasters. The power systems of various countries exist in the natural environment and social environment, and it is inevitable that they will be challenged by extreme natural conditions and the social environment intentionally or unintentionally. At any ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method for drawing a distribution map of the hazard degree distribution of common disasters on transmission lines, so as to solve the problem that the transmission line disasters in the prior art cannot be considered and fully utilized when the operation and maintenance strategy of the transmission line is formulated. The operation and maintenance strategy cannot truly reflect the key points of the transmission line operation and maintenance area, nor can it provide reliable support services and other technical issues during the special operation and maintenance period
