Abstract

The invention provides an evaluation system based on the service life of a power transmission line. The system calculates the characteristic value, the variance contribution rate and the cumulative contribution rate of each principal component through a principal component analysis method, builds an aging evaluation model, and calculates the actual aging degree value of an OPGW optical cable. According to the system, through the OPGW optical cable aging evaluation model, real-time monitoring of various key parameters of the OPGW optical cable is realized.

Description

technical field [0001] The invention relates to the technical field of fiber grating applications, in particular to an evaluation system based on transmission line life. Background technique [0002] With the ever-increasing pressure on global resources and the environment, the deepening of the power marketization process, and the continuous improvement of users' requirements for power reliability and quality, building a safer, more reliable, environmentally friendly and economical power system has become a common goal of the global power industry. . According to the international and domestic development trends, the State Grid Corporation of China (hereinafter referred to as the company) proposes that the construction should be based on the principles of unified planning, unified standards, and unified construction, with the UHV grid as the backbone grid, and the coordinated development of grids at all levels, with informationization, automation, and interaction. A robust ...
