A New Strategy for Optimizing HSIL Transmission Lines

Abstract

This paper presents an efficient procedure for optimizing the electric field at ground level of high surge impedance loading transmission lines. Such lines have the capacity to achieve higher power transmission rates than the conventional ones. The ellipsoidal method is applied in order to maximize the transmitted power and minimize the electric field at ground level through the variation of the conductor's positions in the tower, given its physical and electrical constraints. By means of an efficient new approach to handle the conductors, the optimization gives birth to compact line designs combined with conventional bundles of conductors. Furthermore, it is shown that the proposed strategy can increase the transmitted power, reduce the electric field at ground level, and shorten the running time of the optimization algorithm.

Methodology for Minimizing Electric Field at Ground Level from Transmission Lines Using Sensitivity Analysis

“…The gradient project method has been used in the design of new transmission lines with non-conventional shapes in [17]. In [18] a new methodology takes the optimization of HSIL lines without change the bundle shapes, only change the centroids of each bundle. The ellipsoidal method, proposed in [19] is adopted by [18] for minimizing electric field at ground level.…”
