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.There-fore,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.
