IEC TS 63014-1:2018（E）旨在提供一套全面且一致的指南，以促进使用线路换流器的高压直流（HVDC）系统直流侧设备的规范。对于点对点高压直流输电系统，本文件涵盖了位于换流阀和直流架空线路或电缆终端之间的所有直流侧设备，不包括换流阀本身。对于背靠背高压直流输电系统，本文件涵盖了除换流阀本身以外的所有直流侧设备。

IEC TS 63014-1:2018(E) is intended to provide an overall and consistent set of guidelines to facilitate the specification of equipment for the DC-side of a high-voltage direct current (HVDC) system using line-commutated converters. For point-to-point HVDC transmission systems, this document covers all DC-side equipment located between the converter valves and the DC overhead line or cable termination, excluding the converter valves themselves. For back-to-back HVDC systems, this document covers all DC-side equipment excluding the converter valves themselves.
