Abstract

Some structures in a power system can be modeled as multi-conductor transmission lines or transmission line in order to analyze the transient process when the switches are operated or electromagnetic pulse is imposed. In this paper the modeling of a transmission line and its finite difference time domain (FDTD) method are researched, and then extended to the transmission line network and nonuniform line. After the method is tested, some examples are finally analyzed in order to predict the transient voltage in power substations.

多导体输电线路在变电站暂态分析中的应用
为了分析开关操作或施加电磁脉冲时的暂态过程,可以将电力系统中的某些结构建模为多导体传输线或传输线。本文研究了传输线的建模及其时域有限差分(FDTD)方法,并将其推广到传输线网络和非均匀线路中。在对该方法进行测试后,最后对一些算例进行了分析,以便对变电站的暂态电压进行预测。
