摘　　要：本文讨论了OFDM应用于电力线载波通信的原理,探讨了通信系统的硬件实现,提出了一种基于OFDM的电力线宽带高速通信系统的实现方案,并对其应用于小区集中抄表做了详细的论述分析,试点项目从变电站10kV中压出线到低压用电终端均采用电力线宽带通信,传输速率高达2Mbps以上。The OFDM applied to the principle of power-line carrier communication are discussed in this paper. Hardware implementation of communication system is also proposed.This paper presents an OFDM-based broadband high -speed power line communication system implementations and its use in residential meter reading to do a detailed discourse analysis.The pilot project from 10kV medium voltage substation outlet to the low-voltage electric terminal is used in broadband power line communication,and the transmission rates are up to more than 2Mbps.
