IEC TR 63065:2017+AMD1:2022提供了LCC换流站安全经济运行和维护的基本原则和一般建议的一般指南。这些指南基于过去几十年在世界各地高压直流换流站成功使用的操作和维护实践，可供新的高压直流输电用户参考，以优化操作和维护政策，并协助执行操作和维护工作。本文件仅关注LCC换流站内设备的操作和维护，包括背靠背高压直流输电系统。本文件不包括高压直流架空输电线路、高压直流电缆和电压源变流器（VSC）的运行和维护。

IEC TR 63065:2017+AMD1:2022 provides general guidance on basic principles and general proposals for the safe and economic operation and maintenance of an LCC converter station. These guidelines are based on the operation and maintenance practices that have been used successfully during the last decades at HVDC converter stations all over the world, and can be referred to by new HVDC users to optimize operation and maintenance policy and assist in performing the operation and maintenance work. This document focuses only on the operation and maintenance of the equipment inside an LCC converter station, including back-to-back HVDC systems. The operation and maintenance of HVDC overhead transmission lines, HVDC cables and voltage sourced converter (VSC) are not covered by this document.
