A New Numerical Analysis of Line Equations Considering Corona Loss on Single-Conductor System

Abstract

It is very important to investigate the wave attenuation and distortion due to corona discharge, for the purpose of solving successfully the surge problems on the ultra-high voltage transmission systems. So, in this paper, from the nonlinear line equations considering corona loss on a single-conductor system, the author derived a new ditigal calculation to analyse the attenuation and distortion of the travelling waves caused by corona discharge on a single-conductor system, which is founded on their surge analyser considering corona loss. Then, they compared their digital computation results with the experimental ones on the artificial transmission line by the other researchers and they could successfully elect the optimum values of the corona loss constants of the positive and negative travelling waves.
