带有线性整流转换器的高压直流(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。本规范中使用的“动态性能”一词，是指其特征频率或时域涵盖从瞬态条件到稳态之间范围的事件和现象。它涉及双端高压直流系统与相关交流系统或其元件（如发电厂、交流线路和母线、无功电源等）在稳态或瞬态条件下的动态性能相互作用。假设双端高压直流系统采用由三相桥（双路）连接组成的12脉波换流单元。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配合，并具有双向功率流动能力。本规范不考虑二极管阀。虽然未明确考虑多端高压直流输电系统，但本规范中的大部分信息同样适用于此类系统。本报告仅涵盖换相换流器，包括电容换相换流器电路配置。半导体换相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，并配有稳态（IEC 60919-1）和瞬态（IEC 60919-2）性能的出版物。在编制双端高压直流系统规范时，应考虑这三个方面。系统性能规范与系统各组成部分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，但应关注那些可能影响系统性能规范的要求。不同的高压直流系统之间存在许多可能的变体，因此此处未详细考虑这些变体。本报告不应直接用作特定项目的规范，而应作为基础，用于制定适合特定电力系统输电方案实际需求的适当规范。本报告无意区分用户和制造商在指定工作方面的责任。 [外文原描述]： IEC/TR 60919-3:2009 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.
