A simplified steady-state characterization of long AC transmission lines

Abstract

In this paper, a simplified formulation of the steady-state, distributed-parameter model of AC transmission lines is presented, which is sufficiently accurate in practice for very long lines. The simplification stems from a reduction in the number of parameters involved in the model and provides a better understanding of the effect that the remaining parameters have on the line performance (i.e., transmission capability, power losses, voltage drop, etc.) at different voltage levels and line lengths.
