配电网工频通信技术及其应用

工频通信技术是一种特殊的电力线通信技术，具有独特的通信机理和易实现性。与传统的电力线载波技术相比．最大的优势在于信号能够直接穿透配电变压器，实现跨变压器台区的通信而无需中继，具有通信距离远、抗干扰性能强的特点。文章介绍了基于电力配电网的工频通信系统的构成及其通信方式，分析了工频通信技术的工作原理，详细阐述了信号的调制原理、编码方式及信号检测技术．最后介绍了工频通信技术的主要技术特点及其应用，为工频通信技术在我国配电网中的应用提供参考。

Application of power frequency communication technology in power distribution network

Power frequency communication technology is a special power line communication technology. With the advantages of longer transmission distance and stronger anti-interference performance, the communication signals can be transmitted directly through the distribution transformers to realize cross transformer transmission without any repeaters. In this paper, the author introduces the configuration of power frequency communication system and its communication mode, analyses the working principle, discusses the...
