Computation of Corona Radio Interference Levels in HVDC Transmission Lines

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