Abstract

This article presents the computation of radio interference (RI) lateral profiles produced by corona discharge in a bipolar HVDC transmission line of ±500 kV. The method used to compute the RI levels considers a transmission line model that takes into consideration the skin effect by using the concept of complex penetration depth in the pole conductors and in the ground plane. Also, the attenuation constants are calculated from the line parameters and the bipolar system is decoupled by using modal decomposition theory. Furthermore, the influence of four variables in both RI levels and the maximum bundle electric field is analyzed: sub-conductors radius, bundle spacing, the number of sub-conductors in the bundle and the soil resistivity. Afterwards, vector optimization is applied in order to minimize the RI levels produced by the bipolar line. Finally, RI lateral profiles with both nominal and optimal values are compared.
