Abstract

In this paper, an extensive set of noise measurements on the low voltage part of the electrical power distribution network is presented. These measurements were taken in a laboratory environment for several months by means of a spectrum analyzer. Automatic remote measurement software was specifically designed and used for this purpose. The frequencies considered range from 30 kHz to 1 MHz, well above the allowed band specified in the European standard to communications over the electrical power distribution network. These noise measurements are important for the design of communication systems, such as power line carrier, which use the distribution line as a communications medium. Several kinds of noise are specifically studied, including impulsive noise, switching and non-switching periodic noise and background noise. In particular, the behavior of noise levels as a function of time of day is analyzed. Finally, a statistical model is also shown.

30 kHz ~ 1 MHz配电网低压部分噪声的研究与建模

本文介绍了一套广泛的配电网低压部分噪声测量方法。这些测量是在几个月的实验室环境中通过频谱分析仪进行的。自动远程测量软件是专门为此目的而设计和使用的。所考虑的频率范围从30千赫到1兆赫，远高于欧洲标准中规定的通过电力分配网络进行通信的允许频带。这些噪声测量对于通信系统的设计非常重要，例如电力线载波，它使用配电线路作为通信介质。具体研究了几种噪声，包括脉冲噪声、开关和非开关周期噪声以及背景噪声。特别地，噪声水平的行为作为一天的时间的函数进行了分析。最后，给出了统计模型。
