“….sinh 2 h ave Pij is the magnetic normal field coefficient determined by the coordinates of the i th boundary point and the j th filamentary line current and is given by [13]. (7) Rij is the distance between simulation current point j and match point i; Rj is the fictitious radius of current filament simulation (see Figure 2). We find another expression [12,14] which uses Equation (8) to calculate the magnetic coefficient.…”

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.

“…Most assume that power transmission lines are straight horizontal conductors, parallel to a flat ground, and parallel to each other. The sag due to the line weight is neglected or modeled by introducing an average height for the horizontal line [7][8][9][10][11].…”

“…The effects that occur when these physical agents interact with biological systems depend on the frequency, amplitude of the fields, and exposure time. In the article [3], the installation of a safe distance of high-voltage power lines from residential complexes that are potentially in the zone of its influence is formulated. Measurements of the level of electric and magnetic field strength were carried out taking into account seasonal and daily fluctuations in electrical loads.…”

Nowadays, one of the key issues in the ecological field and environmental protection is the influence of the electromagnetic field distribution intensity generated by low-frequency energy objects on the urban system. The purpose of environmental monitoring is to establish sanitary protection zones, taking into account the necessary maximum permissible conditions, during the construction and commissioning of new energy facilities. The agglomeration environment of the Shymkent city in the Republic of Kazakhstan where there is an increased electromagnetic pollution propagation generated by 110 and 220 kV high-voltage lines has been taken as the object under study. At the initial stage, the geometric parameters of power transmission lines have been determined by ground-based laser scanning and were later used in the main calculations to determine the electric and magnetic field distribution intensity. The mirror image method has been used to determine the electric and magnetic field levels in high-voltage transmission lines. As a result of the calculations obtained a geoinformation map was constructed based on the gradient of electric and magnetic fields in the studied territories using the inversely weighted distance method with the use of the ESRI ARC Gis application program. A three-dimensional characteristic is constructed that visually shows the dependence of the time spent by people in the zone of electromagnetic radiation, which depends on the radiated object. This characteristic is a sanitary protection zone that restricts the routing of line workers.

“…It can be assumed that the interaction of electromagnetic radiation with a living organism will depend on the amount and parameters of the transmitted energy, as well as on the type of irradiated tissue [2]. In the article [3], the specific goal was to determine the safe distance from the electromagnetic field created by high-voltage overhead power lines in the immediate vicinity of the specified section. Measurements were made for both electric and magnetic fields in different months in order to detect the highest levels of electromagnetic field fluctuations during peak loads.…”

Energy objects, installations of high and ultra-high voltage, are considered man-made, dangerous objects in terms of the intensity of the electric and magnetic field distribution, which create ion shells in high-altitude zones and spread a certain radius on the territory of a residential area. In this regard, during the construction and commissioning of low-frequency power facilities, it is necessary to conduct a specific environmental analysis on the selected territory. One of the main sanitary and epidemiological requirements for the construction and commissioning of high – voltage power lines is to take into account changes in the daily and seasonal distribution of electrical loads along high-voltage power lines, which have a continuous dynamic characteristic that increases the level of electric and magnetic field strength. In turn, the development of information support for environmental problems of the territory based on GIS technologies makes it possible to record information about the ecological state of the territory at a specific time and present this state with a set of thematic environmental maps of various territorial or district entities. It should be noted that the above characteristics increase the advantage of geoinformation technologies as an information platform of the database, which will make it possible to obtain data for processing operational analyses and conclusions about the state of the environment around high-voltage power lines.
