One of the basic problems of electric power systems is the absence of normative documents regulating the operation, maintenance and repair of the capital equipment, the service life of which exceeds the normative value. We shall name them «old equipment» (OE). The essence of the difficulties to be overcome is reduced to the absence of methodologies for quantitative estimation of operational reliability and safety of OE, with the subsequent comparative analysis of OE. Considering the science intensity, cumbersomeness and labour intensity of solving this problem, the necessity of development of the relevant automated systems becomes indisputable. In this article, some features are considered of an estimation of an integral indicator and comparative analysis of unique facilities. Here, unique facilities mean those, which have no analogues in terms of the set combination of varieties of significant attributes. The methodological foundations of the synthesis of integral indicators are considered: ensuring the infallibility of the information base; requirements to evaluations of integral indicators; providing the physical essence of the integral indicator; possible types of integral indicators; the comparison of integral indicators of operational efficiency in the framework of the theory of testing statistical hypotheses for one-dimensional random variables is associated with a high risk of erroneous decisions; the assessment of the critical values of the integral indicator is carried out on the basis of simulation modeling within the framework of the fiducial approach.The development of automated systems for collecting and formalizing data on the technical condition of OE, the automated analysis and synthesis of these data, performing standardization of TEI, evaluating integral indicators and some results of comparative analysis, preparing operational recommendations to improve work efficiency, developing appropriate methodological guidelines, indicate the possibility of an objective assessment of the operational efficiency of OE and a decrease in the risk of unacceptable consequences. For an illustration of recommended methods and algorithms, technical and economic parameters of power units with SGI-400 are used.

“…TС of OPL determines the reliability and safety of their work. Therefore, it is relevant to assess the operational reliability indicators by analogy with the individual reliability of power units [6]. The seeming simplicity of this solution is deceptive, and, first of all, because there are no statistics of continuous monitoring TC of the OPL, and it is impossible to estimate the reliability indicators of specific OPLs based on the statistics of failure within one month due to their small number.…”

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.
