Abstract: In order to study and determine the meteorological conditions of transmission line wind damage accidents in Shijiazhuang area,,surface meteorological observations,high resolution fusion live data,upper-air circulation situation field data,radiosonde data and the detailed data of transmission line wind damage accidents at the time of occurrence from 2004 to 2021 were used to analyze the spatio-temporal changes of transmission line wind damage accidents by using climatic statistical methods,weather principles and ArcGis and sufer software,the weather reality characteristics and weather system configuration and radiosonde physical quantities index which were prone to transmission line wind damage accidents were summarized and determined.The forecast accuracy of transmission lines wind damage accidents from 2022 to 2023 was tested by the meteorological conditions of transmission lines wind damage accidents.The results show that,transmission line wind damage accidents are mainly foreign body short-circuit in Shijiazhuang area,which are mainly distributed in the surrounding counties as the center of the main urban area including Gaocheng,Xinle,Zhengding,Luancheng,Jingxing,which mainly occur in the daytime of spring and summer,concentrating from noon to evening,and the frequency of line breakage,wind deviation,tower toppling,and conductor galloping is very small.When the transmission line wind damage accidents occur,the diurnal maximum dominant wind direction of foreign body short-circuit,line breakage and tower toppling is the northwest wind,the diurnal maximum dominant wind direction of wind deviation is the westerly wind,and the diurnal maximum dominant wind direction of conductor galloping is the northeast wind.The benchmark wind force of line breakage,wind deviation and tower toppling is larger,the benchmark wind force of foreign body short-circuit and conductor galloping is smaller.The meteorological conditions of the transmission line wind damage accidents had been well predicted and tested from 2022 to 2023,which had certain guiding significance for the local power department to prevent lightning strike accidents.
