Magnetic Field Modeling and Study Produces of High Voltage Overhead Power Line

With the expansion development of electric power plants systems is raised the continuous consumption of energy resources, this caused more need of the production of high amount power. Consequently, it was an increasing concern about the possible potential dangers resulting from the influence of the power lines on the objects and facilities located nearby. In this presented paper, a simple approach and a two-dimensional (2D) quasi-static numerical modelling of the magnetic field using image method to determine and examine the magnetic induction produced by high voltage overhead transmission lines and its lateral profile is discussed. Several parameters affecting the magnetic induction strength have been studied; it is observed that taking into account the effect of the exact catenary curve of the power line conductors is much more interesting particularly at the mid-span level in the center distance where the magnetic field becomes very significant. According to these values, we note that the exposure limits set by the International guidelines for magnetic induction strength are respected for occupational and public exposure. The simulation results obtained by this method are also verified then are available applied in the literature, a good calculation is achieved and satisfied full enough and it sufficient that confirms the validity and accuracy of the proposed method.
