中文摘要:

本文针对低压电力线载波通信及电力用户用电信息采集应用,分析了窄带OFDM低压电力线载波技术的发展现状以及国际标准化情况。文章首先分析了低压配电网电力线信道的特点,揭示了新一代低压电力线载波通信均采用窄带OFDM调制技术的原因；文章针对我国电力用户用电信息采集电力线载波本地网络,提出了一种协议栈模型,目的是为标准化建立一个分层协议框架,实现不同厂家载波终端的互联互通和互操作。文章最后分析了物理层工频过零点传输的必要性,并对几个主要的窄带OFDM物理层标准进行了比较。

英文摘要:

This paper analyzes the recent development and standardization of narrow-band OFDM technology for low-voltage power line communications(PLC) targeting automatic meter reading and management (AMR/AMM) applications. The pager first introduces the characteristics of low-voltage power distribution lines when used as communication channel, and reveals the reason way OFDM(Orthogonal Frequency Division Multiplexing) has been widely adopted for the new generation of PLC. The paper then proposes a protocol stack model for the local PLC in AMR/AMM system to establish a layered framework for standard development to realize interoperability. Based on this model, the paper finally focuses on the PLC physical layer, analyzes the necessity of zero-crossing transmission, and performs a comparison of the main narrow-band OFDM PLC standards.
