带线路换流器的高压直流（HVDC）系统的性能.第1部分:稳态条件

[中文适用范围]： 本部分IEC 60919提供了关于高压直流(HVDC)系统稳态性能要求的一般指导。它涉及使用由三相桥(双向)连接组成的12脉冲换流单元的两端HVDC系统的稳态性能(见图1)，但不涵盖多端HVDC输电系统。假设两端都使用晶闸管阀作为主要半导体阀，并具有双向功率流动能力。本文档不考虑二极管阀。 本文档仅涵盖线路换向换流器，包括电容器换向换流器电路配置。半导体线路换向换流器的一般要求在IEC 60146-1-1、IEC TR 60146-1-2和IEC 60146-1-3中给出。不考虑电压源换流器。 本技术报告涵盖稳态性能，随后是关于动态性能和暂态性能的附加文件。在准备两端HVDC系统规范时，应考虑所有三个方面。 应认识到系统性能规范与系统单个组件的设备设计规范之间的区别。本文档未定义设备规范和测试要求。本文档还排除了详细的地震性能要求。此外，由于不同HVDC系统之间存在许多差异，本文档不详细考虑这些差异；因此，它不应直接用作特定项目的规范，而是为适合实际系统需求的适当规范提供基础。 本文档涵盖稳态性能，随后是IEC TR 60919-2关于故障和切换以及IEC TR 60919-3关于动态条件的附加文件。在准备两端HVDC系统规范时，应考虑所有三个方面。 [外文原描述]： IEC TR 60919-1:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 60919-1:2020(E) provides general guidance on the steady-state performance requirements of high-voltage direct current (HVDC) systems. It concerns the steady-state performance of two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double-way) connections, but it does not cover multi­terminal HVDC transmission systems. Both terminals are assumed to use thyristor valves as the main semiconductor valves and to have power flow capability in both directions. Diode valves are not considered in this document. This edition includes the following significant technical changes with respect to the previous edition: - Figure 8 and Figure 20 have been updated, a new Figure 18 "LCC/VSC hybrid bipolar system" has been added; - the HVDC system control objectives have been supplemented; - additional explanations regarding the HVDC system control structure have been given; - a new subclause 13.6 on HVDC system protection has been added.
