Analysis on Calculation and Influencing Factors on Lightning Induced Overvoltage of 10 kV Power Distribution Network
摘要
Abstract
In order to study influencing factors on lightning induced overvoltage of 10 kV power distribution network,based on electromagnetic field principle in the stage of lead discharge to lightning return,this paper confirms an optimal calcula-tion model by studying several mathematical models for working out lightning induced overvoltage without considering influ-ence of environmental factors such as temperature,humidity and terrain. It analyzes influencing factors on lightning induces overvoltage by using MATLAB simulation software and obtains relationship between various influencing factors and lightning induced overvoltage. The result indicates that the lightning current amplitude is larger,the line height is higher and the lightning strike distance is closer,the overvoltage amplitude and gradient of wave head is larger.关键词
