Characteristics of wire icing and distribution of standard ice thickness during ice return period in Liaoning province
摘要
Abstract
Studying wire icing characteristics and distribution of standard ice thickness during the ice return period has an important scientific significance to prevent a freezing disaster accident and develop wire of electric power design and related engineering climate feasibility demonstration.Based on wire icing observation data from 1980 to 2011 at 11 meteorological stations of Liaoning province,the characteristics of wire icing and distribution of stand-ard ice thickness during the ice return period in Liaoning province were analyzed by methods of an extreme proba-bility distribution model,a terrain correction and an empirical correction.The results indicate that ice freezing weather often happens in the east mountain areas,south coastal area,west and southeast coastal areas of Liaoning province.The maximum values of standard ice thickness in 30-year,50-year and 100-year return periods are 10.0 mm,11.9 mm and 14.4 mm respectively,and they all occur in Dandong area.关键词
