摘要 电力线宽带通信已成为承载智能电网应用的最重要的通信技术之一,特别针对高级量测系统和家庭局域网,应用尤为广泛。目前绝大多数电力线宽带通信产品都基于正交频分复用、离散多频调制或扩频技术,这些技术在不同场景下的通信性能各异。文章为电力线通信设备提出了性能测试模型,用于评测其传输容量和噪声容限。基于该模型,测试了4种使用不同调制技术的电力线通信设备,进一步分析不同调制技术的性能测试结果并取得一定结论。为减小电气设备引入噪声对通信的影响,文章提出"隔离插座",用于滤除电器侧噪声。 Broadband PLC (Power Line Communication) has become one of the most important communication technologies for Smart Gird applications, especially for AMI (Advanced Metering Infrastructure) and HAN (Home Area Network). Cur- rently, most broadband PLC products are based on OFDM, DMT or Spread-Spectrum technologies. Their performances dif- fer from each other on certain circumstances. This paper proposes a performance testing model to test PLC devices" Transmitting Capacity and Noise Tolerance. Four PLC devices using different modulation technologies respectively are tested. In addition, the performances of different technologies are analyzed and some discussions are made. To reduce the affection of noise brought in communication by electric appliances, an "isolating socket" is introduced, which can filter the noises on the appliance side.
