| Abstract: | as one of the communication options, power line communication has its special advantages. The medium voltage power line communication has a broad application and prospect. The characteristic of channel in medium voltage power line is critical to communication. In order to assess the transmission characteristics of medium voltage power line ,this paper presents an example taken from a specific community in Beijing with distribution voltage of 10 kV. The noise,impedance and transmission attenuation in the frequency of 10-35 kHz were tested. And with the aid of software MATLAB,some data was analyzed and valuable results was obtained. The influence of channel characteristics on medium voltage power line communication is discussed and countermeasures are proposed. |
