IEC TR 60919-3:20 9+A1:2016+A2:2021为高压直流（HVDC）系统的动态性能提供了一般指南。动态性能意味着包括那些特征频率或时域覆盖瞬态和稳态之间范围的事件和现象。在本说明书中不考虑二极管阀。本报告（IEC 60919-3）涵盖动态性能，并附有稳态（IEC 60919-1）和瞬态（IEC 60919-2）性能的出版物。在编制双端HVDC系统规范时，应考虑所有三个方面。本报告不应直接用作特定项目的规范，而是为适合特定电力传输方案的实际系统要求的适当规范提供基础。本报告无意区分用户和制造商对指定工作的责任。第二版取消并取代了第一版，第一版于1999年作为技术规范发布。它构成技术修订。与上一版相比，此版本包括以下重大技术变更: a)本报告仅涉及线路换向转换器； b)对控制系统技术进行了重大改变； c)增加了一些环境约束，例如可听噪声限制； d)包括电容器耦合转换器(CCC)和受控串联电容器转换器(CSCC)。

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.
