Abstract

This paper outlines an optimization calculation procedure used for bundled conductor configuration of compact transmission lines to improve certain operating performance and electromagnetic fields (EMF) management techniques. The objective function of this optimization problem is to allow the charges and surface maximum gradients on all subconductors to be the same and and to be as balanced as possible. As a result, three optimum schemes are induced in this paper for 220 kV transmission lines. Parameters of compact lines and their unbalance, surge impedance, electric field distribution under the line, corona loss and radio noise level are also evaluated. EMF management and field minimization over the right-of-way (ROW) of the optimum schemes are also presented. EMF fields are analyzed, evaluated and compared to attainable fields of standard compact and conventional lines.
