摘　　要：稳定可靠且经济的通信系统是配电自动化系统实施的基础。针对城市以电缆为主供电的配电网特点,提出一种基于配电网电缆屏蔽层的宽带载波通信技术,其物理层通信速率可达30 Mbps,支持TCP/IP协议,可实现对等通信方式。通过对线路输入阻抗和载波通信频谱的测量分析,配置了相应的通信模式,在小陆家嘴地区的实际通信试验表明了该方式的有效性。The stable, reliable, and economic communication system is the basis of the distribution automation system. Based on the features of the cable distribution network, a broadband carrier wave communication technology based on the cable shielding lay is proposed. Its physical layer communication speed reaches 30 Mbps and it supports TCP/IP protocol and peer to peer communication mode. According to the analysis of the input impedance and the frequency spectrum of the carrier wave communication in the 10 kV distribution communication channel, a relevant communicating mode was designed. The communication experiment in the Small Lujiazui area proves the communication mode effective.
