摘要智能电网代表未来电网的发展方向,电力线通信（PLC）技术在其中正发挥着愈来愈重要的作用。由于PLC网络存在阻抗不连续,引发多径传输,直接影响信号接收质量,多径传输特性是影响PLC通信性能优劣的关键因素,虽然之前对PLC多径传输已进行过广泛研究,但这些研究往往基于特定场合确定信息、特性已知情况下的分析,普适性不强,且未考虑多径传输中具有较少反射、较低衰减、并体现其主要特性的最短路径,本文通过构建结合最短路径的PLC多径传输统计模型,无需具体网络分析,旨在为PLC通信系统设计提供更加通用的参考。

Abstract：Smart grid represents the development direction of future power grid. Power line communication (PLC) technology plays a more and more key role in it. Due to the impedance discontinuous in PLC system, which causes multipath transmission and directly influences the quality of signal received, the property of multipath transmission is the critical factor to affect the performance of PLC system. Although there are many studies on multipath transmission, those studies are based on the analysis of specific situation information and features, which doesn’t have good universality and consider the shortest path that has less reflection and attenuation. Combined with the shortest path, the paper analyzes and constructs the statistical model of PLC multipath transmission, without specific network analysis, which can offer reference for the design of PLC system.

Key words： Smart grid power line communication (PLC) multipath transmission the shortest path
