摘　　要：噪声特性作为电力线信道的1个重要特性,对低压电力线载波通信有着较强的影响作用。我国低压电网环境复杂,电力线上存在着各种强时变性的噪声干扰。结合现场某一典型台区的电能采集情况以及采集到的噪声数据,分析得出电力线噪声在频域与时域2个方面对低压电力线载波通信的影响规律。Noise characteristics, as an important feature of power line channel, has a strong effect on low-vohage power line carrier communication. There are a variety of strong time-varying noises on power line due to complex environment of low-voltage grid. According to the electric energy and noise acquisition data from a typical area of the site, this article analyzes the impact of the power line noise on the low-voltage power line carrier communication in the frequency domain and time domain.

关 键 词：噪声特性 低压载波通信 噪声分析
