线路换流换流器（LCC）高压直流换流站运行和维护指南

[中文适用范围]： 本技术报告提供了 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导。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运维实践，可供新的高压直流用户参考，以优化运维策略并协助执行运维。维护工作。本文件仅重点介绍 LCC 换流站@（包括背靠背高压直流输电系统）内设备的运行和维护。本文件不涵盖高压直流输电线路@高压直流电缆和电压源换流器（VSC）的运行和维护。注：通常，高压直流换流站的买方和供应商之间的协议包括有关特定系统合同要求的具体要求。此类特定要求将取代本文档中提到的一般/典型描述，并且本文档中提到的所有功能不一定适用于所有系统。 [外文原描述]： IEC TR 63065:2017(E) 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.
