摘要

本文介绍了变电站开关合闸和大气放电引起的高频过电压瞬变时接地网的行为。网格的仿真基于传输线法(TLM)。仿真的输出是由这种高频过电压输入在网格的某些点上引起的感应电流和传导电流的总和。细导线由Naylor和Christopoulos开发的节点表示。

Analysis of real overvoltage transient in a TLM-modeled

This paper presents the behavior of a grounding mesh in presence of a high-frequency overvoltage transient caused by switch closing in electrical substations and atmospheric discharges. The simulation of the mesh is based on Transmission Line Method (TLM). The output of the simulation is the sum of induced and conducted currents caused by such high-frequency overvoltage input in some spot of the mesh. Thin wires are represented by nodes developed by Naylor and Christopoulos.
