Abstract

In this paper, a new hybrid approach to modeling the magnetic induction produced by HV overhead power line which combines the current simulation method (CSM) and adaptive simulated annealing algorithm (ASA) is discussed. The aim of the ASA algorithm is to find the optimal position and number of current loops used in bundles conductors for an accurate magnetic induction. Several parameters affecting the magnetic induction have been studied; it is observed that, taking into account the effect of conductor sag is much more interesting particularly at the mid-span length where the magnetic induction becomes very significant, the results also indicated that the maximum magnetic induction levels are less than the limits recommended by the ICNIRP standard for general public and occupational exposure. The calculated results are compared with those obtained from the COMSOL 4.3a Multiphysics software. A good agreement has been reached.

Highlights

Electricity is an essential factor to stimulate economic growth needed to improve and facilitate the daily quality of life of all human population, the continued rise in the world's population and with the tendency to concentrate in large cities
In view of the above, this study aims to determine the levels of the magnetic induction created in the vicinity of High Voltage (HV) power transmission lines, using the current simulation method (CSM)
This paper presents a novel optimized technique for quasistatic modelling and analyzing the magnetic induction generated by HV power line based on the current simulation method (CSM) coupled with the adaptive simulated annealing (ASA)

Summary

Introduction

Electricity is an essential factor to stimulate economic growth needed to improve and facilitate the daily quality of life of all human population, the continued rise in the world's population and with the tendency to concentrate in large cities. This has created an unprecedented demand in the consumption of electrical energy and has accelerated the installation of new high voltage power transmission lines near or in the populated areas. It is important to accurately analyze the distribution of electric and magnetic fields in the vicinity of high voltage overhead power lines, in order to improve protection of human health and the environment [4,5,6]
