摘　　要：低压电力线通信的可靠性是影响其普遍应用的最大问题。文章阐述了国内外学者在频率选择、输入阻抗、噪声干扰及信号衰减特性等方面的研究成果。其中,噪声干扰特性对低压电力线通信可靠性影响最大。文章重点介绍了噪声干扰特性分类、特点及建模等方面的研究成果。通过分析各特性现有数学模型,建立精确模型是提高低压电力线通信可靠性的基础,也是今后电力线通信领域发展的重要方向。The reliability issue of low-voltage power line communication is the biggest problem impeding its universal application. The domestic and foreign scholars＇ research results of frequency selection, input impedance, noise interference and signal attenuation characteristics are described. The noise interference characteristic has the greatest impact on the reliability of low-voltage power line communication. This paper introduces the classification, features and modeling research of the noise interference. By analyzing the existing mathematical models of the characteristics, we conclude that the establishment of accurate models is the foundation of improving the reliability of low-voltage power line communication. and will be the important direction of power line communication development in the future.
