Abstract
With matlab,detailed simulation research on the power frequency electrical field and power frequency magnetic field of UHV transmission line was made.The method to establish the simulation models and concrete modules of the program were introduced,and calculated examples were used for simulation.The result of simulation showed that,lightning shield lines had few effects on electromagnetic field beneath the transmission lines,while electrical field above the ground became weaker as the transmission lines became higher toward the ground.From the result it can be seen that it can reduce the power frequency electric field beneath the transmission lines to increase height of transmission lines and so on.The result of simulation had important guiding meaning to the construction of UHV transmission lines.
