Quantitative analysis of the operational reliability of overhead power lines

Abstract

The relevance of ensuring the efficiency of equipment, devices and installations (facilities) of electric power systems increases every year, becoming the most important problem of maintaining energy security. The decrease in work efficiency is due to a number of factors, but, above of all, due to an increase in the relative number of objects whose service life exceeds the standard value. An illustration of the methodology for quantifying, comparing and ranking the monthly average values of the operational reliability indicators of 110 kV and higher overhead power lines is given in order to identify and restore the wear of the least reliable lines.
