Methodology for Assessing the Degree of Aging Overhead Power Transmission Lines of EES

Abstract

The main objects of the EES, the service life of which exceeded the standard value, are increasingly beginning to determine the efficiency of work every year. This manifested in an increase in the number of automatic emergency shutdowns, the number and complexity of emergency-hazardous defects. Organization of operation, maintenance and repair of these facilities recommended carried out according to their technical condition. And since the technical condition determines the reliability and safety of the object, it is therefore recommended to take these properties into account more fully. These recommendations in the EES carried out at a high quality level, intuitively, according to operating experience.In this article, as distributed objects of continuous operation, overhead power transmission lines (OPTL) with a voltage of 110 kV and higher, the service life of which exceeds the standard value, are considered. The issues of quantifying the degree of significance of the aging problem for a set OPTL, their classification and methodology for assessing the difference in the degree of aging when classifying them according to given types of characteristics are considered. The methodology and algorithm of methodological support for the management of the EES and network enterprises during the organization of operation, maintenance and repair, been developed.
