为了实现配电网高速、可靠通信,对其信道特性进行了研究。从多导体传输线理论出发,在试验场地架设了三相传输线,测得不同情况下的信号传输规律,采用MATLAB对其建模仿真并验证结果的正确性。由于信号在传输线上的传输规律与线路的一次参数密切相关,分析了如何根据线路的型号、材质、布线结构来计算不同频率下线路的一次参数矩阵。分析结果表明,在衰减较小的频段,采用合理调制方式可以实现信号高速、可靠传输。

In order to realize high-speed and reliable communication in the distribution network,the channel characteristics are studied and three-phase transmission lines are set up in the test field for measuring the signal transmission line in different conditions employing the multi-conductor transmission line theory.The MATLAB simulation is performed to verify the correctness of the results.As the signal transmission law is closely related to the primary parameters of the transmission line,an analysis is made of the parameter matrix calculation of the parameters according to the type of line,material quality and configuration at different frequencies.The results show that it is likely to realize high-speed and reliable signal transmission in rather low attenuation band employing rational modulation.
