Abstract

The space electric field generated by high-voltage AC transmission lines will act on people and objects around them through electrostatic induction. When the induced voltage is too high, the human body will experience transient electric shock, so it’s necessary to limit the ground electric field. To address the problem of electric field effects on human body under AC transmission lines, the beetle antennae search algorithm (BAS) optimization charge simulation method (CSM) is applied to calculate the electric field distribution under EHV AC transmission lines, and the finite element method is used to analyze the effects of power frequency electric field intensity on human body under 500kV EHV AC transmission lines. The results show that the presence of the human body reduces the electric potential around it and the power frequency electric field will be strongly distorted at the human head. The distribution of the electric field and induced current density around the human body under 500kV AC transmission lines is quantitatively calculated to provide a reference for assessing the safety of the human body exposed to EHV AC transmission lines.

基于BAS-CSM算法的超高压交流输电线路下人体感应电场研究

高压交流输电线路产生的空间电场会通过静电感应作用于周围的人和物体。当感应电压过高时，人体会产生瞬态触电，因此有必要对地电场进行限制。针对交流输电线路下电场对人体的影响问题，采用甲虫天线搜索算法(BAS)优化电荷模拟方法(CSM)计算了超高压交流输电线路下电场分布，并采用有限元法分析了500kV超高压交流输电线路下工频电场强度对人体的影响。结果表明，人体的存在降低了人体周围的电势，工频电场在人的头部会发生强烈的畸变。定量计算500kV交流输电线路下人体周围的电场分布和感应电流密度，为评估人体接触超高压交流输电线路的安全性提供参考。
