| 摘 要： | 主要对超高压串补输电线路的串补系统及串补线路区内外故障时行波信号在频域上的透射系数和反射系数及其幅频特性进行了详细的仿真分析.结果表明,串补系统对低频信号分量衰减较为严重,且串补度越大,衰减越严重.串补线路区内和区外故障时行波高频信号会出现明显差异,且差异的大小与线路边界的频率特性有关.

| Abstract: | In this paper,the series compensated system of the extra-high-voltage transmission line is analyzed and simulated.In addition to this,the reflective and refractive coefficients of the travelling wave when internal fault or external fault occurs and their amplitude-frequency characteristics are also studied.The results indicate that the series compensated system makes the high attenuation of the low frequency signals,which will be higher when the degree of the series compensation increases.The high frequency... |
