中文摘要: 利用1983—2008年26年河北省灾情直报数据资料，统计分析大风灾情记录及大风灾害对河北电网设施损坏的时空分布特征。结果表明：（1） 7～12级大风是造成电网安全事故的主要灾害性大风；（2） 大风灾害致电网安全事故年变化存在显著差异，最多高达43起/年，最少年仅为2起/年；（3） 月分布呈显著的单峰曲线变化，6—8月为大风灾害电网安全事故高峰期，占全年大风灾害总次数的83％；（4） 空间分布极不均匀，燕山南麓、太行山东麓以及沿海地区是电网灾害事故相对多发区域；（5） 通过典型个例分析、成因分析，提出灾害性天气服务对策，为加强河北省电力行业气象服务及防灾减灾提供参考。

Abstract:By using the gale disaster data in Hebei Province from 1983 to 2008, the characteristics of wind disasters leading to power system security incidents in time and space are analyzed. Results showed that: (1) The high winds of 7 to 12 scales are main factors for the electrical network security accident; (2) Wind induced power disasters (WIPD) have significant changes yearly, the most disasters can be up to 43 cases in a year, and the least only 2 cases; (3) Monthly distribution of WIPD presents a remarkable unimodal pattern, power disasters are mainly concentrated in the summer half year, the 97.8% of total disasters happened in April to October; (4) The spatial distribution of WIPD is extremely uneven, the electrical network disaster accidents were relatively more in Tangshan, Baoding and Cangzhou, but there were relatively few in Zhangjiakou and Chengde region. On this basis, through the case analysis and causation analysis， the prevention measures were proposed, which provided the reference to strengthening the entire province meteorological service， and the disaster prevention and reduction.
