摘要
高压输电线路周围的电磁场分布是电网建设单位、电力运行管理单位和公众关注的焦点。以110 kV同塔双回高压输电线路为研究对象,对50 Hz工频下输电线路周围空间电磁场分布进行研究。选用COMSOL Multiphysics仿真软件,构建高压输电线路模型,设定模型参数,建立激励条件和边界条件,对150 cm以下地面高度的电场强度和磁感应强度进行仿真。研究发现:磁感应强度最大值为0.35534μT,电场强度最大值为423.11 V/m,分别仅为ICNIRP标准公众暴露限值的0.17%和8.46%。110 kV高压输电线路周围的电磁环境是安全的,不会对公众身体健康产生较大影响。
The electromagnetic field distribution around the high voltage transmission line is the focus of the power grid construction unit,power operation management unit and public.Taking the 110 kV onetower double-circuit high voltage transmission line as the research object,the spatial electromagnetic field distribution around the transmission line under the 50 Hz power frequency is studied.Using the COMSOL Multiphysics simulation software,the model of the high voltage transmission line is constructed,the parameters of the model are set,the excitation conditions and boundary conditions are established,and the electric field intensity and magnetic induction intensity of the ground height below 150 cm are simulated.It is found that the maximum value of magnetic induction intensity is 0.35534μT,and the maximum value of electric field intensity is 423.11 V/m,which are only 0.17% and 8.46% of the ICNIRP standard public exposure limit,respectively.The electromagnetic environment around the 110 kV high voltage transmission line is safe and will not have a great impact on the public health.
