Research on the Induced Electric Field of Human under EHV AC Transmission Lines Based on BAS-CSM Algorithm

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.
