METHODS FOR PREVENTING ICE PROCESSES OF HIGH-VOLTAGE AIR LINES IN AREAS WITH A SEVERE CLIMATE CHANGE

Abstract

This article discusses the freezing processes that occur in winter on the 220 kV Zarafshan-Muruntau high-voltage overhead lines and methods for eliminating them. The article describes the dangerous consequences of ice accumulation on wires, weighting of wires and the occurrence of power outages. Based on experimental studies, mechanical means of protection against freezing - vibration, roller and automatic devices - were analyzed. The coefficient of ice mass reduction as a result of mechanical action and methods for determining it using modeling are indicated. The possibilities of real-time ice mass estimation and control using MATLAB and SCADA systems were also analyzed. The results confirm the effectiveness of using mechanical devices in practice
