摘要
Abstract
In recent years the power cable lines occupy much higher proportion of transmission lines in urban power transmission and distribution system, and people begins paying attention to electromagnetic environmental problem caused by power cables. On the basis of referring to the electromagnetic environmental characteristics and impact factors of overhead transmission lines and considering the features of power cable itself, the modeling of main electromagnetic environmental impact factors on power frequency magnetic field and corresponding algorithm are researched, and simulative analysis on typical distribution of three kinds of power frequency magnetic fields caused by power cable is performed. Simulation results show that the triangular arrangement of three-phase power cable can reduce magnetic field intensity at ground surface to a great extent. Finally the power frequency electromagnetic fields caused by two power cable lines are tested and the measured power frequency electromagnetic field intensities, which basically conform to the value of theoretical analysis, are negligible; the measured power frequency magnetic induction density levels are lower than the magnetic field exposure limits specified in current national standards.关键词
