摘要

为了实现敏感电子设备(如变电站和住宅中的信息设备和数字继电器)的电磁兼容，研究接地系统在雷击浪涌作用下的瞬态性能是非常重要的。地埋导线接地网被认为是高压变电站和大型电站接地系统最有效的解决方案，地埋接地环是通信建筑和住宅接地系统的有效解决方案。本文介绍了基于时域有限差分(FDTD)方法的接地网单元暂态性能的计算机分析和实验结果，并通过实验结果和分析结果的比较，证实了这种新的模拟方法对于分析接地网暂态性能是可行的

Computer analysis of transient performance of grounding grid element based on the finite-difference time-domain method

It is important to study the transient performance of grounding systems for lightning surges in order to realize electromagnetic compatibility (EMC) of sensitive electronics, such as information devices and digital relays in substations and/or residential houses. Grounding grids of buried conductors are considered as the most effective solution for grounding systems of high-voltage substations and large plants, and buried earth rings are effective solutions for grounding systems of communication buildings and residential houses. In this paper, computer analysis based on the finite-difference time-domain (FDTD) method and experimental results of the transient performance with respect to a grounding grid element, which is also considered as a buried earth ring, are presented and it is confirmed that the novel simulation method is practical for analyzing the transient performance of the grounding grids through comparison of experimental and analytical results
