A TRIDIMENSIONAL APPROACH FOR MAGNETIC FIELD CALCULATION IN POWER SYSTEMS

This paper presents the basis and application of a three-dimensional magnetic field computational method for electric power systems. The main application of this algorithm is the evaluation of the environmental impact of transmission and distribution power systems which produces a growing public concern. An advantage of this method is to depict in quality and quantity the magnetic field density due to geometrically complex three phase installations such as overhead power lines or power substations, including underground cables. The routines were programmed using Fortran and Matlab softwares, making use of the advantages of each of them. The calculation begins with the data upload of the electric system. The system's characteristics comprise the spatial coordinates (beginning and end of…
