IEC TR 63127:2019+AMD1:2024 CSV focuses on the system design of converter stations. It is applicable to point-­to-­point 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.
