+AMD1:2016+AMD2:2021 CSV 修改件2.带线路换流器的高压直流（HVDC）系统的性能.第3部分:动态条件

[中文适用范围]： 本技术报告提供了关于高压直流（HVDC）系统动态性能的一般指导。动态性能，如本规范中所用，旨在包括那些特征频率或时域覆盖瞬态条件和稳态之间范围的事件和现象。它关注于由于两端HVDC系统与相关交流系统或其元件（如发电厂、交流线路和母线、无功功率源等）在稳态或瞬态条件下的相互作用而产生的动态性能。假设两端HVDC系统使用由三相桥（双路）连接组成的12脉冲换流单元。假设换流器使用晶闸管阀作为桥臂，采用无间隙金属氧化物避雷器进行绝缘协调，并具有双向功率流能力。本规范中不考虑二极管阀。虽然未明确考虑多端HVDC输电系统，但本规范中的大部分信息同样适用于此类系统。本报告仅涵盖线路换向换流器，包括电容换向换流器电路配置。半导体线路换向换流器的一般要求见IEC 60146-1-1、IEC 60146-1-2和IEC 60146-1-3。不考虑电压源换流器。本报告（IEC 60919-3）涵盖动态性能，伴随有关稳态（IEC 60919-1）和瞬态（IEC 60919-2）性能的出版物。在准备两端HVDC系统规范时，应考虑所有三个方面。系统性能规范与系统单个组件的设备设计规范之间存在差异。虽然此处未定义设备规范和测试要求，但请注意那些会影响系统性能规范的内容。不同HVDC系统之间存在许多可能的差异，因此这些差异未详细考虑。本报告不应直接用作特定项目的规范，而应提供基础，以制定适合实际系统需求的适当规范。本报告无意区分用户和制造商对指定工作的责任。 [外文原描述]： IEC TR 60919-3:2009+A1:2016+A2:2021 provides general guidance on the dynamic performance of high-voltage direct current (HVDC) systems. Dynamic performance is meant to include those events and phenomena whose characteristic frequencies or time domain cover the range between transient conditions and steady state. Diode valves are not considered in this specification. This report (IEC 60919-3) which covers dynamic performance, is accompanied by publications for steady-state (IEC 60919-1) and transient (IEC 60919-2) performance. All three aspects should be considered when preparing two-terminal HVDC system specifications. This report should not be used directly as a specification for a specific project, but rather to provide the basis for an appropriate specification tailored to fit actual system requirements for a particular electric power transmission scheme. This report does not intend to discriminate between the responsibility of users and manufacturers for the work specified. This second edition cancels and replaces the first edition, which was issued as a technical specification in 1999. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) this report concerns only line-commutated converters; b) significant changes have been made to the control system technology; c) some environmental constraints, for example audible noise limits, have been added; d) the capacitor coupled converters (CCC) and controlled series capacitor converters (CSCC) have been included.
