摘要
采用等效电荷法和镜像法,建立输电线路三维计算模型;考虑输电线路各个区域上分布的电荷不均匀,对模型进行离散;利用Matlab平台计算出空间三维电场强度和磁感应强度,同时可实现电场强度和磁感应强度等值线图分布计算,并将计算过程程序化。将计算结果同CDEGS软件计算结果和实测值分别进行对比分析,结果证明了本程序的有效性和准确性。
A three-dimensional numerical model based on equivalent charge method and image method is built. Considering the nonuniformity distribution of electric charge on power transmission line, the three-dimensional electric field intensity and magnetic induction intensity are calculated by Matlab. Besides, the electric field intensity and magnetic induction intensity isoline distribution map can be calculated at the same time. The calculation results of the program are proved to be effective and accurate by comparing with the calculated results of CDEGS software and actual measured values.
