The purpose of this PAS is to provide a guide for the design of electrode stations for HVDC links
intended for ground return. This design guide was prepared by the CIGR? Working Group 14.21:
HVDC Ground Electrode Design during the period 1995-1998.
It is not the purpose of this report to provide detailed instructions on how to work out an HVDC
link from the initial idea to final decisions on sites, ratings, constructional principles for converter
stations and for connecting lines/cables. In the often hectic planning phase of a new link, the main
emphasis will be concentrated on converter stations and the line/cable, while less attention is paid
to a simultaneous evaluation of possible current return principles.
