直流输电线路下方建筑物附近离子流场的计算
Calculation of the Ionized Field Under DC Transmission Lines With Buildings Nearby
摘要
Abstract
The electric field around the building under DC transmission lines is so complex that the calculation method based on the Deutsch assumption which cannot consider the effect of the wind when solving the ionized field near the building would result in large errors theoretically.Based on the upstream finite element method(FEM),a new iterative controlling method was used to calculate the ionized field around the building model under a DC test line.The iteration was efficiently convergent,and the calculation result agreed well with the measured data,which indicates that the method based on the upstream FEM method is valid for solving the ionized field under DC transmission lines with buildings nearby.Taking the wind velocity into account,the ionized field of the test line was calculated,and it was found that the effect of the wind on the electric field around the building is remarkable,thus the effect should be considered when calculating the electromagnetic environment under DC transmission lines with buildings nearby.关键词
