摘要： 利用石家庄地区2004—2021年输电线路风害事故资料和发生时地面气象观测资料、高分辨率融合实况资料、高空环流形势场资料、探空资料,采用气候统计方法和天气学原理分析了输电线路风害事故的时空变化,确定了易发生输电线路风害事故的天气实况特征、天气系统配置和探空物理量指标,并对2022—2023年输电线路风害事故预报的准确性进行检验。结果表明:石家庄地区输电线路风害事故以异物短路为主,主要分布在以主城区为中心的周边县区(包括藁城、新乐、正定、栾城和井陉),多发生在春季和夏季的白天时段,集中在中午到傍晚时段,断线、风偏、倒塔、导线舞动发生次数很少。输电线路风害事故发生时,异物短路、断线、倒塔的日极大风速对应风向以西北风为主,风偏的日极大风速对应风向以偏西风为主,导线舞动的日极大风速对应风向以东北风为主。断线、风偏、倒塔发生时,日极大风力较大;异物短路、导线舞动发生的日极大风力较小。输电线路风害事故发生的气象条件在2022—2023年得到较好的预测检验,对当地电力部门防范风害事故有一定指导意义。

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.
