| 摘 要： | 针对学生宿舍区、教学实验区和居民区3个典型的电力环境,使用低压电力线噪声采集设备采集噪声数据,处理得到10~500 kHz噪声功率谱,进而分析电力线噪声幅值随典型通信频率及在不同时段的变化趋势.结果表明:噪声幅值随频率的升高而降低,低频段噪声对电力线通信影响较大,在用电高峰时段噪声幅值会有10~35 dBμV的波动.因此,就抗干扰程度而言,载波频带为100~450 kHz的美国标准比载波频带为3~148.5 kHz的欧洲标准更适合电力载波通信传输.

| Abstract: | The low-voltage power line noise acquisition equipment was used to collect noise data in three power environments including the student dormitory,teaching experimentation area and residential area,processing to get 10 ~ 500 kHz noise power spectrum was gotten variation tendency of the power line noise amplitude with typical communication frequency and different periods were analyzed. The results showed that： noise amplitude will decrease with the increase of the frequency; Low-frequency noise has a greater impact on the power line; During power peak periods,noise amplitude will fluctuate 10 ~ 35 dBμV. Therefore,as far as noise level,the America standard carrier frequency band of 100 ~ 450 kHz was more suitable for power line carrier communication than the European standard carrier frequency band of 3 ~ 148. 5 kHz. |
