Response Bounds Analysis for Transmission Lines Characterized by Uncertain Parameters

This work is focused on the study of multiconductor transmission lines (MTL) with uncertain parameters; i.e. the values of r, l, c and g can vary in an interval. The wavelet expansion in time domain is used in order to obtain an accurate and low cost representation of the line in terms of an algebraic system. The wavelet representation applied to the study of MTL with variation of the electrical parameters, allow us to easily calculate a set of equivalent distributed generators which represent the effects of the disturbance produced by the parameter variation. This analysis allows us to directly evaluate the response bounds related to the parameters uncertainties without performing repeated simulations (Morite Carlo Method).
