Assessment Approaches of Climate Factors Influence for Design of Overhead Transmission Lines

A plan for the development of the electric power industry at the present stage has become impossible excluding climate change, especially when it comes to ensuring the sustainability of the power grid infrastructure. In this paper, it was carried out the analysis of the regulatory requirements of international, Russian and foreign standards for the power grid infrastructure design under the climatic factors influence. Comparative tables have been formed reflecting the consideration of climatic factors (wind and ice/snow) on the objects of the power grid complex with the designation of the main indicators that are evaluated for the choice of construction and materials for the execution of poles and wires of overhead transmission lines in Russia, the EU and the USA. Recommendations on improving the mechanisms for climatic factors in the design of overhead transmission lines were formed, a list of recommended adjustments of design loads, maps of climatic zoning and the period of repeatability for Russian reference documents was indicated. The results can be used to improve the regulatory framework and develop more effective strategies for the design and operation of power grid facilities.
