Abstract

A novel method to determine the transfer functions of power line networks is presented. Although a number of the evaluation methods have been proposed, the major drawbacks are on approximation, complexity and intuitiveness. The presented method overcomes those by making use of backward impedance transfer and forward voltage transfer techniques. Additionally, the novel method offers an extra feature that transfer functions at any points throughout the network can be simultaneously determined in one implementation. This paper first reviews some major existing methods. Then, the method of impedance and voltage transferring is derived and fulfilled with an implementation algorithm and mathematic description. Lastly, an implementation of the method on a sample network for the transfer function is demonstrated. Channel capacity is adopted as the measure for the quality of the channels.
