Current state and problems of reliability of power supply systems of electrical complexes of industrial enterprises

Abstract

In accordance with the Energy Strategy of Russia until 2035 and the Decree of the Government of the Russian Federation "Improving the reliability and quality of power supply to consumers of electric energy through the introduction of new technologies and optimization of the activities of territorial grid organizations", the issues of improving the reliability of power supply of electrical complexes of industrial enterprises in a market economy are of particular importance.This article presents the results of a survey of managers and specialists of the services of the chief power engineer of industrial enterprises, representatives of design institutes, equipment manufacturers, university researchers on the existing problems of reliability of power supply systems of industrial enterprises. The expediency of substantiating the identification of the current situation by the main reliability indicators and their relationship in the existing economic conditions for calculating the reliability of power supply systems is substantiated. A comparative analysis of the responses of respondents of energy services is presented, their interpretation is given.The main problems in the following blocks are identified: the quality of the enterprise's energy supply and its reliability; the reliability of energy distribution within the enterprise and control of the influence of installed electrical equipment on the quality of the electrical network; knowledge regarding reliability and interest in carrying out such calculations. Recommendations are given on the identified problems, including the analysis of individual indicators of reliability of power supply to industrial enterprises.
