摘要
噪声干扰是影响电力线通信可靠性的最主要因素之一,主要包括五类噪声:有色背景噪声、窄带噪声、异步于工频的周期脉冲噪声、同步于工频的周期脉冲噪声和异步脉冲噪声。搭建了背景噪声测量电路,测量了实际电力线通信信道噪声,分析了电力线通信信道噪声的一般特性,为今后建立电力线通信信道噪声的可靠模型提供了理论支持。
Noise interference is one of the main influencing factors on power line communication＇s reliability. The noise includes： colored background noise, narrowband noise, periodic impulsive noise asynchronous with the power frequency, periodic impulsive noise synchronous with the power frequency, asynchronous impulse noise. In this paper, the background noise measurement circuit is built, the actual power line communication channel noise is measured, and the general pow- er line communication channel noise characteristics are analyzed as well. This provides a theoretical support for the establishment of a reliable power line communication channel noise model in the future.
