Electromagnetic Transient Performance of Optimally Designed High Surge Impedance Loading Lines

The objectives of this paper are (i) to create a revolutionary design for transmission lines by shifting phase configurations and subconductors into “unconventional” arrangements that are geometrically optimized to maximize natural power, and (ii) to study electromagnetic transients owing to simultaneous and sequential line energization for unconventional high surge impedance loading (HSIL) lines via an inverse numerical Laplace transform method. Compared to conventional lines, all unconventional HSIL line designs proposed in this paper led to less severe surges, indicating another advantage to these lines.

I. Introduction

The next-generation of unconventional, self-reactive power compensation HSIL lines may become a game-changing technological innovation that will replace traditional overhead line designs to mitigate the contemporary challenges of power transmission.
