雷雨大风与河北电网灾害特征分析
The Characteristic Analysis of Thunderstorm Gale and Electrical Network Disaster in Hebei
摘要
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.关键词
