| 摘 要： | 本文使用有限时域差分法(FDTD)对由局部放电产生的电磁波在GIS典型结构(直线型和L型结构)中的传播特性进行了仿真研究。通过设置不同的电磁波激发方向、对比不同测量角度的信号时域和频域特征、以及比较两种结构的仿真结果,获得了TEM波和TE模波在直线型和L型结构中的传播特性,以及L型结构产生的反射波特征。仿真结果表明,影响电磁波传播的因素主要包括电磁波激发方向、模波速度色散和模波模式转变等。

| Abstract: | Propagation characteristic of electromagnetic wave which is excited by partial discharge in GIS is simulated based on the method of FDTD.The transmission characteristics of TEM and TE,and reflected wave which is generated by Lshaped tanks are analyzed in the straight and L-shaped tanks of GIS structure,through setting the different directions of electromagnetic,and comparing the time and frequency domain results of electromagnetic wave in different structures and measurement angles.There are some factors that influence E-M wave transmission characteristic,such as directions of electromagnetic wave,wave velocity dispersion and wave mode transformation. |
