Line Configuration Analysis of an Overhead Ground Wire the Effect of Electric Fields Distribution around the HV Power Transmission Line Using Finite Element Method

摘要

This paper has proposed a mathematical model of electric fields caused by high voltage (HV) conductors of electric power transmission systems by using a set of second-order partial differential equations (PDE). This study has considered line configuration of an overhead ground wire (OHGW) the effect on electric fields emitted around a 500-kV power transmission line. Comparison among seven test cases configuration, varying height of OHGW, varying distance between two-line of OHGW and varying size of OHGW, has been illustrated. Computer-based simulation utilizing the two-dimensional finite element method (FEM) in the time harmonic mode, instructed in MATLAB programming environment with graphical representation for electric field strength has been investigated. From all test cases, the calculation line of 1.0 m above the ground level is set to investigate the electric fields acting on a human.
