摘　　要：为更好地评估低压智能电能表的各项通信性能、建立专门的智能电能表通信性能仿真平台及克服低压电力线通信过程中高阻抗、高噪声、高污染的影响,研发了性能良好的干扰屏蔽措施,根据传导噪声的传导和耦合机理,提出一种传导噪声隔离供电电源设计方案。试验证明,该方案低压电力线窄带载波通信频段内的传导噪声隔离效果优于80dB,保持有效信号正常通信。To calibrate the communication performance of low-voltage smart electrical meter, a specified communica- tion simulation platform need to be built, which can eliminate the effect of high resistance and high noise. Some novel in- terference shield approaches are introduced in this paper. More significantly, a conducted noise isolating power source for low power line communication is proposed based on conducted noise coupling principle. Test show that noise isolating per- formance of this proposal is better than 80dB, which keeps the normal communication qualification.
