Abstract

In this paper, the Radio Interference (RI) lateral profiles produced by corona discharges in a hybrid transmission line are computed. The applied method is based on the calculation of the conductor surface voltage gradients considering the interaction between AC and DC circuits. Then, the radio interference levels produced by each phase/pole conductor are calculated by means of empirical formulas presented in previous works for two weather conditions: heavy rain and fair weather. Two hybrid line configurations are compared in order to determine which one produces the lowest RI levels. After that, vector optimization is applied in order to minimize the RI levels produced by the best hybrid line configuration, considering three independent variables: subconductors radius, bundle spacing, and the number of subconductors in the bundle. Finally, RI lateral profiles with both nominal and optimal values are compared.
