基于核密度估计的输电线路走廊杆塔-地闪复合密度统计方法
Statistical Method of Flash-tower Composite Density in Transmission Line Corridor Based on Kernel Density Estimation
摘要
Abstract
Due to the shortage of China's land resources,muti-circuit transmission lines sharing corridor are very common.Line corridor coverage area is very limited compared with the range of lightning activity.The density of line towers is not the same in the corridor.Therefore,it is a worthy problem to study how to measure the impact of lightning activity in the corridor.We adopt the kernel density estimation to carry out statistics of the flash density and the lightning flash density of transmission line corridor in Baise area.According to the calculation of correlation coefficient,the correlation between flash density,lighting flash density and tower density is crosschecked.After comparison,it is obtained that the correlation between lightning flash density and the flash-tower composite density is the highest,which is 0.85.However,the correlation coefficient between transmission line corridor flash density and lightning density is only 0.51.As a result,a concept of flash-tower composite density is put forward,which can be used to measure the lightning distribution within the transmission line corridor effectively.关键词
