摘要
分析了配电网电力线通信信道存在的高噪声、变化的低阻抗、高衰减等一般性问题 ,阐述了电力线扩频载波通信的基本原理及其抗时变衰减、抗随机干扰的优越性 ;从应用角度总结了配电网电力线扩频载波通信技术的国内外现状以及在配电网自动化、楼宇自动化以及公用通信领域的典型应用。
Based on the analysis of the transmission characteristics of high noise level,varying impedance and high damping of the medium and low voltage distribution lines,the fundamentals of the spread spectrum carrier power line communication and its substantial potential in anti- interference and anti- fading are described.The development of the distribution line communication and its applications in distribution automation,automation of the high- rise buildings and some other public communication areas are also reviewed and a conclusion is reached that the high rate data communication via distribution line is an active direction.
