GIS-based gridding power transmission line operation and maintenance difficulty quantitative evaluation method

Abstract

The invention discloses a GIS-based gridding power transmission line operation and maintenance difficulty quantitative evaluation method, which uses power transmission line operation and maintenance difficulty evaluation data of each grid unit, adopts an entropy weight method as a weight calculation model, combines with GIS system spatial analysis, formulates power transmission line operation and maintenance difficulty grades of different operation and maintenance difficulties, can be used for objectively grading a final operation and maintenance difficulty value, avoids the subjectivity caused by manual grading, formulates different operation and maintenance difficulty intervals, and enables the operation and maintenance personnel to be able to query the operation and maintenance difficulty range of each sample specifically according to the grading intervals. In addition, the GIS-based gridding power transmission line operation and maintenance difficulty quantitative evaluation method provides a power transmission line operation and maintenance difficulty quantitative evaluation reference based on geological positions for a power grid operation and maintenance patrol inspection department by means of geological information visualization service offered by the GIS, provides guidance suggestion for a power grid operation and maintenance department in the aspects of operation and maintenance management, personnel assignment and resource optimization, avoids excessive manpower and material resource investment, and saves cost.

Description

technical field [0001] The invention relates to a method for quantitatively evaluating the difficulty of operation and maintenance of transmission lines, in particular to a method for quantitatively evaluating the difficulty of operation and maintenance of transmission lines based on GIS grid. Background technique [0002] As a basic component of power grid operation, transmission lines have a vital impact on the normal operation of power supply facilities. Ensuring the normal operation of transmission lines and formulating reasonable operation and maintenance strategies have always been the focus of power grid operation and maintenance departments. Considering the harmful high-voltage safety hazards of transmission lines, residential areas with high population density and the vicinity of main roads are avoided in the initial planning and design. Therefore, the construction location is remote and the terrain environment is complex, which brings difficulties difficulty. Alt...

Problems solved by technology

Considering the harmful high-voltage safety hazards of transmission lines, residential areas with high population density and the vicinity of main roads are avoided in the initial planning and design. Therefore, the construction location is remote and the terrain environment is complex, which brings difficulties difficulty

Although maintenance personnel can understand the operation and maintenance information through external data and other information, they cannot comprehensively evaluate the difficulty of operation and maintenance

On the other hand, the risk sources of transmission lines involve multiple factors. In addition to objective factors such as conventional equipment and personnel, it also involves external factors such as regional characteristics, natural disasters, pollution flashover volcanoes and external damage, which further increases the risk of transmission lines. Difficulty of Comprehensive Assessment of Line Operation and Maintenance Difficulty

Since the quantitative standards of most external factors are difficult to unify, the operation and maintenance department has relatively little research and excavation on them, which indirectly affects the operation and maintenance decision-making, reduces work efficiency, and increases unnecessary waste of resources , consume a lot of manpower and material resources
