Abstract:
By means of the lightning tripout data from electricity department and the cloudtoground lightning data obtained by the lightning position network from the Zhejiang Meteorological Service, the spatial and temporal distributions of electric power tripout events from 2007 to 2011 in Zhejiang Province are analyzed. The distances between tripout events and cloudtoground lightning and the relationship between the parameters of cloudtoground lightning data and the voltage classes of lightninginducing tripout events are analyzed. The results show that diurnal and monthly variation of lightning tripout events and cloudtoground lightning exhibit a singlepeak structure, and the correlation coefficients are 0.9905 and 0.9881, respectively. However, their spatial distributions are not significantly correlated. The lightning current intensity inducing tripout events of 110 kV, 220 kV, and 500 kV power lines is below 90 kA in most cases, and the current intensity inducing the tripout of 500 kV line is relatively lower. The distances between cloudtoground lightning and tripout tower are less than 2 km, so are the nearest distances between cloudtoground lightning and transmission lines.
