| 摘 要： | 从传输线的理论出发,建立了山西某535线路的一段仿真模型,基于该模型研究了10 kV电力线信道的衰减特性,并将仿真所得的衰减频点与实际线路中可以通信的频点相对比,验证了模型的正确性.分析了在分支线路上增加电缆对信道的影响以及载波通道间的串音衰减.增加电缆后由于存在了波阻抗的不连续点,行波在传输过程中发生反射和折射,产生了较大的衰耗.变电站内电气设备间和导线间的电磁耦合的存在,使得载波通道间产生串音衰减.

| Abstract: | The attenuation characteristics over 10 kV medium voltage power line channels using the transmission line theory are analyzed.And the simulation model of a section line of Shanxi 535 lines is established based on transmission line theory.In order to verify the correctness of the model,the results of simulation are compared to the actual line.The impact of channel when the cable is added to branch line and the crosstalk attenuation of the carrier channel are analyzed.There are non-consecutive points of the w... |
