| 摘 要： | 传统的雷电地域分布采用雷电日(雷暴日)的概念,但所有可听雷声中云间雷占有一定比例,而只有地面落雷密度才对电网防雷有影响.从高级调度中心的建设需求出发,根据雷电定位系统统计数据计算出地区落雷密度,从而使华东地区线路跳闸率计算方法更精确,可供防雷的分析研究参考.

| Abstract: | Traditionally the lightning geographical distribution is characterized by thunderstorm day.However the cloud-to-ground lightning flashes and the flashes over the cloud layers account for different proportion of the total audible strikes and in case of the lightning protection problem,the density of cloud-to-earth lightning flashes is of more significance.The author computed the regional density of the cloud-to-earth lightning flashes based on the lightning location system and calculated the trip-out rate of... |
