基于电压源换流器（VSC）的高压直流（HVDC）输电性能第1部分:稳态条件

[中文适用范围]： 本技术报告旨在呈现有关电压源换流器 (VSC) 高压直流 (HVDC) 传输系统稳态性能要求的“现状”一般指导。它涉及利用功率双向流动换流器的双端 VSC HVDC 传输系统的稳态性能。本文件涵盖了 VSC HVDC 传输系统的不同配置，包括对称单极、非对称单极、带接地回路的双极、带专用金属回路的带接地回路的带专用金属回路的刚性双极配置。不同 VSC HVDC 传输系统之间存在许多变化。本文件不详细考虑这些变化；因此，它不能直接用作特定项目的规范，而是为系统稳态性能要求提供一般基础。通常，性能规范基于包含两个 VSC HVDC 换流站的完整系统。然而，有时 VSC HVDC 传输系统也可以从多个供应商单独指定和购买，而不是从单个交钥匙供应商购买。在这种情况下，可以考虑各部分与整体 VSC HVDC 系统性能目标的协调，以及各部分与系统的接口的清晰定义。VSC HVDC 传输系统的主要部件在 IEC 62747 中介绍。参考 IEC 62747，HVDC 变电站/换流站定义为 VSC HVDC 传输系统的一部分，包括在一个位置安装的一个或多个 VSC 换流单元，连同建筑物、电抗器、滤波器、无功功率供应、控制、监控、保护、测量和辅助设备。交流变电站不包含在本文件中。本文件提供有关系统设计程序以及 VSC HVDC 传输项目设计中涉及的技术问题的指导和辅助信息。本文件可用作起草采购规范的依据，并作为项目实施的指南。 [外文原描述]： IEC TR 63363-1:2022(E) is to present the "state of the art" with respect to general guidance on the steady-state performance demands of VSC HVDC transmission systems. It concerns the steady-state performance of two-terminal VSC HVDC transmission systems utilizing converters with power flow capability in both directions. Different configurations of a VSC HVDC transmission system are covered in this document, including the symmetrical monopolar, asymmetrical monopolar, bipolar with earth return, bipolar with dedicated metallic return and rigid bipolar configurations. There are many variations between different VSC HVDC transmission systems. This document does not consider these in detail; consequently, it cannot be used directly as a specification for a particular project, but rather to provide the general basis for the system steady-state performance demands. Normally, the performance specifications are based on a complete system including two VSC HVDC converter stations. However, sometimes a VSC HVDC transmission system can also be separately specified and purchased from multiple vendors instead of single turnkey vendor. In such cases, due consideration can be given to the coordination of each part with the overall VSC HVDC system performance objectives and the interface of each with the system can be clearly defined. The major components of the VSC HVDC transmission system are presented in IEC 62747. Referring to IEC 62747, an HVDC substation/converter station is defined as that part of the VSC HVDC transmission system which consists of one or more VSC converter units installed in a single location together with buildings, reactors, filters, reactive power supply, control, monitoring, protective, measuring and auxiliary equipment. The AC substations are not covered in this document. This document provides guidance and supporting information on the procedure for system design and the technical issues involved in the system design of VSC HVDC transmission projects for both owners and contractors. This document can be used as the basis for drafting a procurement specification and as a guide during project implementation.
