Reprint An experimental set-up for characterizing the residential power grid variable behaviour

The objective of this work is to establish the basic setup and methodology for analyzing the effect of common disturbances on the residential power line channel response regarding time and network topology. Such information is necessary in the process of developing a method of real-time channel sensing used in a multi-carrier communication system that performs dynamical sub-channel bandwidth allocation. Measurements are performed on a controlled experimental power line network, constructed in the image of common residential circuits, but isolated from external sources of disturbance. Transmission line and two-port network theory are used to produce a theoretical model of the network transfer function, which conforms to the experimental results.
