摘要
低压电力线路作为信息传输的信道由于不需进行新的通信网络的投资与建设,因而越来越多地受到人们的关注,针对电力线路实际的电气参数,根据电力线理论以及实际电力线路的具体特性,建立了电力线理想等效电路和电力线载波通信的仿真电路模型,根据仿真电路模型利用PSp ise仿真软件对电力线路实际的电气参数进行了离线仿真研究,通过仿真研究得出了电力线信道的各个电气参数是如何影响通信质量的,为今后设计实际低压电力线载波通信系统电路及选择电路的有关参数时提供了理论依据。
As the transmission channel, low voltage power line has no need of new investment and construction of communications network, it has attracted the most attention. According to the actual electric parameter and theory of power line and its material characteristic, perfect equivalent circuit of power line and simulation model of its carrier telecommunication are built. Based on the model, off - line simulation is taken by using PSpice simulation software, how each electric parameter of power line channel can influence communication quality is reached. It provides the theory base for designing actual circuit of low voltage power line carrier communication system and choosing related parameters for the future.
