摘要
Abstract
Substation is place where strong current and weak current of power system concentrate most,and its elec-tromagnetic environment is complex.Power frequency current,over-current caused by lightning,operating current and the impulse current and so on,will cause a variety of electromagnetic disturbance, and equipment and buildings in substation can block electromagnetic radiation to some degree, and effects of refraction and reflection make electro-magnetic interference situation more complex.Therefore,electromagnetic environment of substation,effects of objects in the substation on the propagation of electromagnetic radiation worth deep researches.By means of FEKO,this pa-per sets electric dipole made up of a length of wire as interference source,simulates and analyzes over radiation situa-tion of electric dipole in free space.We set interference source near a simplified transformer model,simulate and ana-lyze filed intensity of transformer nearby.Next,set interference source in different places of simplified substation mod-el,and simulate by FEKO,and obtain the electric field distribution graphs of interference source in horizontal plane of different height,and analyze interference result of substation by graphs.关键词
