Mapping the Recurence of Icing Thickness Growth Rate
The study on the ice thickness growth rate recurrence of power grid not only guides the anti icing design of transmission lines,but also provides reference for the deployment of anti icing measures and emergency decisionmaking.In this paper,we use 97 meteorological observation station data in Hunan combined with the probability distribution function of Pearson type III,calculate ice growth rate recurrence.And we analyze its 15 years,30 years,50 years and 100 years spatial distribution.It finds that the serious icing of Hunan power grid locate in Chenzhou.It has the characteristics of long duration,large thickness and fast growth of icing.The second serious areas are the central and northern part of Hunan.The ice accretion in the central region has no significant change at different recurrence periods.In southwest Hunan,although the duration of ice accretion is longer,the icing growth is slow.
