Abstract

Inadequate safety issues that may arise from the 500kV substation for live working, field strength and induced current distribution under 500kV bus are analyzing based on the finite element method. By dividing cells and functional for extreme perform spatial field distribution calculation, proper analysis of the field intensity distribution space is carried out. And the spatial field distribution substation is gotten, then to get the induced current in accordance with the space field strength and induced current relationship formula. Building the brief mannequin, and making a simulation with An soft for electromagnetic field around the human body under the Pipe Type Bus Bar of a 500kV substation distributed, electromagnetic field around the body charged distortion and induced current distribution under the bus are analyzed.
基于有限元法的带电工作磁场强度和感应电流分析
基于有限元法分析了500kV变电站带电工作时可能出现的安全不足问题,500kV母线下的场强和感应电流分布。通过划分单元和极值函数进行空间场分布计算,对场强分布空间进行了合理的分析。并得到变电站的空间场分布,然后根据空间场强与感应电流的关系公式得到感应电流。建立了简要的人体模型,并用An软件对500kV变电站管式母线下分布的人体周围电磁场进行了仿真,分析了母线下人体周围电磁场的带电畸变和感应电流分布。
