【摘要】 传统的二维模型已不能正确描述输电线下存在建筑物时高压线下工频电场分布,提出了采用模拟电荷法,综合考虑线路弧垂,建立有建筑物时工频电场的三维数学模型,对电场进行仿真,给出仿真结果,与没有建筑物时比较,有建筑物时电场分布更加复杂,并产生畸变点。最后按此模型采用目前流行的VC和M atlab混合编程的方式编制了仿真软件。更多还原

【Abstract】 Since the traditional 2-D model can not correctly describe the power frequency electric field distribution under the high voltage line with buildings constructed beneath the line,the 3-D mathematic model is presented which adopts the charge simulation method and considers the line sag.The 3-D model was used to simulate the electric field,and the results are given.Compared with the no-building situation,the electric field distribution with buildings is more complicated with aberration points.By using the mixed programming of the popular VC and Matlab,the simulation software was finally developed based on the model.更多还原
