DIGITAL TRANSMISSION PERFORMANCE OF CARRIER CHANNELS ON DISTRIBUTION POWER-LINE NETWORKS

The analysis of the transmitting features of wire-to-ground and wire-t o-wire carrier channels on power distribution networks is performed bo th in the frequency- and in the time-domain. A new formulation of the lossy ground return parameters is considered, which applies in a wide frequency-range and in case of poorly conductive sail. The sensitivity of the frequency-spectra and longitudinal profiles of the transmitted voltages to the distribution system configuration, load termination a nd ground resistivity is investigated. The eye-diagram approach is use d in order to ascertain the transmission quality of carrier channels o n tree- and mesh-type networks, in case of high capacity digital signa ls.
