| Along with the rapid development of the electric technology, the harm caused by the electromagnetic radiation has been more and more grievous. Electromagnetic radiation pollution can jam the electric equipment, even could hurt people's body. It is conjectured that the electromagnetic radiation pollution will be the primary pollution instead of other pollutions in the future.This paper discusses primarily on the following subjects: According to the electromagnetic radiation criterion from"Regulation for electromagnetic radiation protection"(GB 8702-88);"Technical regulations on environmental impact assessment of electromagnetic radiation produced by 500KV ultrahigh voltage transfer power engineering"(HJ/T 24-1998) etc, design a test software about electromagnetic radiation. Calculate and analyze the electromagnetic radiation distribution of power frequency electric field under 500KV super-voltage transmission line and the influential factors, amend and compare the formula of prediction model using the basis of charge equivalent method and image method; citing the base station, combine with antenna gain and antenna directivity, predicted the different area's electromagnetic radiation condition according to different electromagnetic directivity and compare with practice measure data to analyze; calculate and analyze the near field distribution of symmetry dipole antenna. Finally append them to the software.The detecting and measuring platform software is developed using Microsoft Visual Basic programming language. It also has a friendly man-machine interface. |
