Abstract

This article presents an analysis of radio interference (RI) lateral profiles produced in different design options for a bipolar HVDC transmission line proposed for the Turkish Power Transmission System. The method used to compute the radio interference levels considers a transmission line model that takes in consideration the skin effect in 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. The results show how some proposed designs can exceed the recommended RI limits while others can produce RI with values considered acceptable.
