Analysis of Icy Accidents in Electrical
35–110 kV Networks of the Donbass Power System
Abstract: During the operation of overhead power transmission lines, dangerous effects on overhead line elements are possible that are not provided for by the conditions of normal operation and lead to damage and accidents. The article is devoted to the analysis of accidents in the electric networks of
35–110 kV of the Donbass power system, which occurred as a result of ice formation on the conductors of overhead power transmission lines. Examples of technological violations (accidents) that led to the most serious consequences due to damage to overhead line supports during icy-frost deposits on conductors in the autumn-winter period of 2023–2024 are given. The distribution of technological violations on transmission lines objects of the power system under icy-wind effects, as well as the distribution of types of technological violations associated with damage to supports, has been studied. The main components of a comprehensive system of measures to prevent icy accidents and improve the reliability of electrical networks are proposed.
Keywords: overhead power transmission lines (OPTL), conductor, icy-frost deposits, technological disruption (accident).
