摘　　要：低压电力线信道特性是设计低压电力线载波通信系统的基础。文中采用自行设计和研制的测量系统对将低压电力线用做高频通信网络时的电气特性 ,包括输入阻抗特性、信号衰减特性和系统的噪声特性等 ,进行了大量的试验研究。在此基础上 ,建立了一个将低压电力网用做高频载波通信信道的模型。该模型的建立提供了一个实用、有效的平台 ,为低压电力网载波通信系统的研究和设计打下了良好的基础。The characteristics of power line channel are the foundation of designing the low voltage power line carrier communication system. With the measuring system designed by the author, many experiments are made to investigate the electrical characteristics of power line used as high frequency carrier communication channel including the characteristics of input impedance and signal attenuation as well as noise. Based on the experimental results, a model for the power line channel in high frequency is proposed. This model provides a practical and effective platform for exploring and designing power line carrier communication system.
