摘　　要：以智能用电信息采集系统的建设为背景,介绍了低压宽带电力线载波通信技术的Homeplug AV标准和Homeplug GP标准,对比分析了二者PHY层与MAC层的差异。就OFDM子载波的调制方式BPSK、QPSK和16QAM信号的性能、误码率和能量效率展开了比较。仿真结果表明:Homeplug AV标准下的宽带电力线载波技术可以获得较高的系统容量,适用于局域网络网关,以汇聚信息流形成坚强组网拓扑;Homeplug GP标准下的宽带电力线载波技术功率消耗低、数据通信速率稳定,适用于智能家居、低压电力集抄和充电桩计量等领域。Homeplug AV standard and Homeplug GP standard of low voltage broadband power line carrier communication techniques are introduced taking smart power electric data acquisition system as background. The differences between PHY standards and MAC standards have been analyzed. Performance, BER and power efficiency of BPSK, QPSK and 16QAM signals have been compared. Simulation results show that broadband power line carrier technique of Homeplug AV can achieve higher system capacity, which is applicable for network gateway to gather information flow and form a strong topology. Low power consumption and stable data communication speed under Homeplug GP technique is applicable for smart home, low voltage power meterreading and charging pile metering.
