Abstract
The main objective of this study is to establish the level of reliability of electricity distribution systems, which is currently characterized by multiple problems, because, at present, these systems have a complex configuration and are affected by a significant number of refusals, conditioned by various influencing factors. To achieve the proposed objective, the most important indicators were selected, which allow estimating the level of reliability of electricity distribution systems, regardless of structure and configuration. The main results obtained are those related to the application of the proposed reliability assessment procedure for estimating reliability indicators, which are of significant importance for the operation of electricity distribution systems, thus providing the possibility of justified planning of measures to prevent refusals and increase the level of reliability of the examined systems.
