| 摘 要： | 中压配电线是广泛存在的资源，利用中压配电线来实现数据通信对配电自动化及公用通信是最经济、最便捷和最有效的方式。为了评价中压配电线作为通信媒体的传输特性，文中对位于南京市郊的一条中压10kV配电线路进行了现场测量，对100-450kHz频率范围内的线路阻抗、噪声及传输衰耗特性进行了系统的分析研究，并且利用计算机对测量的大量数据进行了统计分析，给出了一些具有价值的结论，进而讨论了其对宽带数字载波通信的影响。

| Abstract: | Using the meddle voltage distribution line as a communication medium for the distribution automation and public communication is an effective and economic way compared with other modes because of the plentiful infrastructure.In order to assess the transmission characteristics of the medium distribution line,this paper presents an example in Nanjing area.Statistical analysis of the measurement results is introduced,and the effects on broadband digital carrier communication are discussed too. |
