System design is the basis of construction and operation of HVDC systems. It defines the overall philosophy for the HVDC transmission system and enables the ratings and specifications for the equipment integrated in the project.

This document focuses on the system design of converter stations. It is applicable to point-topoint and back-to-back HVDC systems based on line-commutated converter (LCC) technology.

This document provides guidance and supporting information on the procedure for system design and the technical issues involved in the system design of HVDC transmission projects for both purchaser and potential suppliers. It can be used as the basis for drafting a procurement specification and as a guide during project implementation.Cross References:IEC 60633IEC TR 60919-3IEC 61803IEEE 1124:2003IEC 60287 (all parts)IEC TS 61973IEC TR 63014-1CIGRE TB 518CIGRE TB 352IEC TS 62344CIGRE TB 92IEC 60060-1IEC TR 60919-2CIGRE TB 68CIGRE TB 115IEC 60076-6IEC 60700-1IEC TR 62001 (all parts)IEC/IEEE 65700-19-03CIGRE TB 563IEC/IEEE 60076-57-129IEC 60071-5IEC TR 60919-1:2010
