摘　　要：电力线载波(PowerLine Communications,PLC)在用电设备智联网中承担了接入层和传输层的大部分通信任务,对于数据的真实性、可靠性、时效性起着至关重要的作用。介绍了当前电力线通信发展现状及需要解决的关键技术,包括了基本信道特性、基于OFDM的调制解调技术、多节点的接入方式、基于实际电力接入网结构的子网划分策略,并结合用电设备智联网的架构和组网方式提出了适宜的路由寻址策略。Power Line Communication （PLC） undertakes most communication tasks in access layer and transport layer of the Smart Interact of Power Consumption Equipments （SIPCE）, and plays a crucial role on the facticity, reliability and timeliness of the data transmission via the powerline. This paper introduces the current development status of the PLC as well as some key technologies to be solved, including the basic channel characteristics, modulation techniques based on OFDM, multi-nodes access techniques, sub-netting issues based on real powerline access structure. In addition, based on the architecture and networking mode of the SIPCE, this paper proposes the available routing and addressing strategies.
