摘要
笔者简要介绍了矩量法的基本原理。针对电力系统线性结构特点,阐述了矩量法用于计算电力系统工频电磁场的工程算法。基于该算法,使用国际知名软件包CDEGS计算了某地区实际输电线路的工频电磁场分布,计算结果与实测符合得很好。还分析了降低输电线路在地面附近电场强度的实用性措施,以供工程参考。
The fundamental principle of the moment method and its engineering algorithm for computing power frequency electromagnetic field around transmission line in power system is introduced. Based on the algorithm, the distribution of power frequency electromagnetic field around an actual transmission line is calculated with the HIFREQ program of the software CDEGS, and the calculation results agree well with the measured values. In addition, some practical measures for reducing the electrical field strength above ground are analyzed.
