摘　　要：目前电力线载波通信面临着传输速率、可靠性及电磁兼容等诸多方面的挑战。近年来,迅猛发展的超宽带无线通信技术为应对这些挑战提供了新的思路。文章首先简要介绍了超宽带通信技术,在分析低压电力线信道特性的基础上,用SystemV iew软件建立超宽带脉冲通信系统模型,并进行了原理性仿真;探讨将超宽带技术(UWB)应用于电力线高速通信的可行性,并就其中的关键和难点进行了归纳和阐述;最后展望了应用前景。At present, Power Line Communication （PLC） faces many challenges, such as the transfer rate, reliability, and electromagnetic compatibility etc. The Ultra-Wide Band （UWB） wireless communication technology has been developing rapidly in recent years, and it offered a new thinking to reply these challenges. The article introduces UWB technology briefly at first; and then on the basis of analyzing channel characteristic of the low-voltage power line, the systematic model of UWB pulse communication was set up with System View software, and the simulation results are given. The feasibility of ultra-wild band technology applying in high-speed power line communication is discussed, and furthermore some key issues in practice are presented. Finally, the prospect of UWB applied to power line communication is brought forward.
