Distribution line carrier is one of the media alternatives
available for providing two-way communications between the
substation and various feeder locations. Distribution line
carrier propagation measurements reported in previous
literatures have shown that the propagation of signals on a
power distribution line is difficult to predict due to the
complexity of distribution systems. Analytical tools that can
analyze signal propagation on the distribution lines would
facilitate the study of this communication scheme for
distribution automation. In this paper, an efficient approach
based on three-phase bus admittance matrix and sparse matrix
and sparse vector techniques is proposed to calculate the
received signal voltage at any feeder point. Sparsity
techniques used to reduce execution time and memory space
requirement. This Analytical tool is used to analyze the
effects of frequencies, transformer types, loads, and network
configurations on distribution system line carrier signal
attenuation.
