[中文适用范围]： 本文件包含关于多供应商高压直流(HVDC)电网系统(也称为HVDC电网)的规划、规范和执行的指南。本文件使用"HVDC电网系统"或"HVDC电网"来描述具有两个以上HVDC站连接到共同直流电路的高压直流输电系统。直流电路可以是径向或网状拓扑或其组合。本文件适用于额定直流电压高于50kV(对地)的高压系统。本文件涵盖以下技术方面： • HVDC电网与交流系统的协调 • HVDC电网特性 • HVDC电网控制 • HVDC电网保护 • AC/DC换流站 • HVDC电网设施，包括直流开关站和HVDC输电线路 • 研究及相关模型 • 测试 不在本文件范围内的内容包括： • DC/DC换流站 [外文原描述]： IEC TS 63291-1:2023 contains guidelines on planning, specification, and execution of multi-vendor HVDC grid systems also referred to as HVDC grids. The terms "HVDC grid systems" or "HVDC grids" are used in this document to describe HVDC systems for power transmission having more than two HVDC stations connected to a common DC circuit. The DC circuit can be of radial or meshed topology or a combination thereof. In this document, the term "HVDC grids" is used. While this document focuses on requirements specific for HVDC grids, some requirements are considered applicable to all HVDC systems in general, i.e., including point‑to‑point HVDC systems. Existing IEC (e.g. IEC TR 63363-1 [1]), Cigre or other relevant documents have been used for reference as far as possible. Corresponding to electric power transmission applications, this document is applicable to high voltage systems, i.e. those having typically nominal DC voltages higher than 50 kV with respect to earth are considered in this document. NOTE While the physical principles of DC networks are basically voltage independent, the technical options for designing equipment get much wider with lower DC voltage levels, e.g. in case of converters or switchgear. This document covers technical aspects of: - coordination of HVDC grid and AC systems, - HVDC grid characteristics, - HVDC grid control, - HVDC grid protection, - AC/DC converter stations, - HVDC grid installations, including DC switching stations and HVDC transmission lines, - studies and associated models, - testing. Beyond the scope of this document, the following content is proposed for future work: DC/DC converter stations.
