چکیده
|
This paper investigates relation and influence between electromagnetic fields generated by high voltage transmission lines and human health. a novel pylon with optimal phase arrangement through possible configuration is presented by optimizing a multiobjective cost function consists of the electric field, magnetic field, and the segments cost. for comparison between current pylons and the proposed pylon, the human model is placed below high voltage overhead lines and then electromagnetic fields and current density is simulated. electromagnetic fields from overhead lines are calculated by using plscadd and plstower software based on maxwell rsquo;s method. the human body is modeled by the finite element method (fem) in matlab. results show that the new pylon decreases electromagnetic fields distribution on the human body and this pylon also mitigates the rightofway width by its special position of phase conductors.

Abstract
|
This paper investigates relation and influence between electromagnetic fields generated by high voltage transmission lines and human health. A novel pylon with optimal phase arrangement through possible configuration is presented by optimizing a multiobjective cost function consists of the electric field, magnetic field, and the segments cost. For comparison between current pylons and the proposed pylon, the human model is placed below high voltage overhead lines and then electromagnetic fields and current density is simulated. Electromagnetic fields from overhead lines are calculated by using PLSCADD and PLSTOWER software based on Maxwell rsquo;s method. The human body is modeled by the Finite Element Method (FEM) in MATLAB. Results show that the new pylon decreases electromagnetic fields distribution on the human body and this pylon also mitigates the rightofway width by its special position of phase conductors.
