摘要

The paper deals with harmonic analysis of HVDC submarine cables. The longitudinal series impedance matrix is computed with reference to armoured cables. The results are also compared with Finite Element models showing a very good agreement. This investigation can be considered the first step of more detailed further analysis about the propagation of harmonics on the d.c. and a.c. sides. Some novel matrix procedures are presented in order to pass from the loop impedance to the longitudinal series impedance matrix and to eliminate the grounded conductors. Comparisons with ATP-EMTP are not possible for a four metallic layered (core, screen, reinforcement and armour) HVDC cable since ATP-EMTP only takes three metallic layered cables into account.
