Measurement and Characterization of an MV Distribution Network for Data Communication

Abstract

This study discusses a measurement campaign carried out over medium-voltage distribution networks, covering the frequency band 100-500 kHz. From the obtained data set, magnitude of channel frequency responses, average channel attenuation, additive noise power spectral density, and achievable data rate are investigated. A numerical analysis shows that the magnitude of the channel frequency response presents a low level of frequency selectivity in the analyzed frequency band. Also, the measured channels can achieve data rates over 3 Mbps.

Ambient Energy Harvesting: The Potential of Additive Noise in Urban and Rural Medium-Voltage Electric Power Networks

“…The urban MV channels corresponds to PL segments from 10 m up to 1,300 m. In relation to rural channels, these lengths range from 2,000 m and can reach up to 4,360 m. The CFR estimates cover the frequency band from 100 kHz to 500 kHz, which is lower and upper bounded by the adopted inductive coupler and an analog low-pass filter. For more details about the CFR estimation, the applied measurement setup and its components see [12].…”

“…This appendix shows the maximum, mean, and minimum values of the magnitude associated with the MV-PLC CFRs in Figs. 10 and 11 for the urban and rural environments, respectively [12].…”
