This paper outlines an optimization calculation procedure used for a 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 as balanced as possible. As a result, three optimum schemes are induced in this paper for 200 KV transmission lines. The parameters of compact lines and their unbalance, surge impedance, electric field distribution under the line, corona loss and radio noise level are also evaluated. Electromagnetic field management and field minimization over the right-of-way of the optimum schemes are also presented. EMF fields are analyzed, evaluated and compared to attainable fields of standard compact and conventional lines. (C) 1998 Elsevier Science Ltd.
