The question of defining ice and wind loads on overhead power transmission lines in complex relief
Abstract: The paper deals with the definition of ice and wind loads for overhead power transmission lines in a complex terrain. The authors have used a comparative approach to the definition of climatic loads on overhead lines in mountainous terrain on the example of different techniques. As sources of information used data from the climatic zoning Regulations for Electrical (amended in 1965 and 2006). As well as used data closest weather stations in the 50-year period in order to clarify the microclimatic zonation. Analysis of climatological information led to the conclusion that the methodology of Regulations-2006 provides the most reliable design. However, the use of weather stations located in different orographic conditions, due to their weak correlation leads to a significant increase in the loads on the OPTL. Analysis of the topographical conditions of the location of weather stations and OPTL, together with the definition of conditions of formation of ice and wind effects can significantly reduce the load.
Keywords: overhead power transmission lines (OPTL), ice and wind loads, weather data, climatic zoning.
