The risk assessment of power network is beneficial to improve the reliability of power system. It only considers the condition of the equipment itself in conventional power network risk assessment methods, but lacks of a consideration of the various influence factors in the network. A comprehensive risk assessment method based on Equipment Condition and entropy is proposed to evaluate power network...
Here we report characteristics of more than 100 cases of Narrow Bipolar Events (NBEs) occurred during two thunderstorms on the basis of our analysis of the dataset collected by a GPS based three-station time of arrival (TOA) lightning location system deployed in Northeast China during the summer of 2010. All of the NBEs were of positive polarity and the amplitude of VLF/LF initial pulse of NBE was...
Lightning-related fatalities, injuries and property damages reported in China from 1997 to 2009 are summarized by using the National Lightning Hazards Database. Therefore, characteristics of the incidents including 5,033 deaths, 4,670 injuries and 61,614 damage reports are analyzed. For the spatial distribution of lightning disasters in China, the eastern costal and southern areas have more frequent...
From analysis of VLF/LF bandwidth electric and magnetic fields and associated VHF emission of 245 NBE-related records during a thunderstorm, the temporal context of NBEs with ordinary lightning discharges was studied. Both negative and positive NBEs could occur in the thunderstorm and -NBEs tended to occur at a much higher altitude than +NBEs. 26 of 377 NBEs were identified as isolated ones since...
