Abstract

The paper considers the issue of expertise of \“Bashkirenergo” LLC and methods of wires and lightning-conductors of overhead power lines deicing. We have made a duration analysis of the icy season for LLC \“Bashkirenergo” energy network and its influence on the reliability of power equipment. We have undertaken an analysis of current activities to prevent and eliminate icing accidents. Using the vast experience of LLC \“Bashkirenergo” and academic basis of the Ufa State Aviation Technical University we have developed our own comprehensive contingency plans to prevent and eliminate icing emergencies. These plans include – 1. Preparation and further updating of zoning plans depending on glazed crust thickness; 2. Preparation and further updating of zoning plans depending on recurrence and intensity of conductor galloping; 3. Implementation of active and passive methods of deicing; 4. Implementation of active and passive methods of limitation of conductor galloping; 5. Implementation of computer-aided icing surveillance systems; 6. Staff training and development. The above plans to enhance the reliability of overhead power lines during intensive icing periods will help to improve ice melting systems, ensuring prompt data communication from respective sections of high-voltage lines and extending melting areas. Based on analytical investigations proven by experimental studies we may draw necessary conclusions on the most effective deicing methods and means in the territory of Bashkortostan. All this together have allowed for the increase in reliability of electrical networks of \“Bashkirenergo” LLC during the autumn and winter season. Keywords: ice, transmission lines, map of ice thickness, de-ice systems, galloping control, wireless monitoring, staff trainings.
