标准摘要
[中文适用范围]: 本部分IEC 60919作为技术报告,提供了关于高压直流(HVDC)系统瞬态性能和故障保护要求的指导。它涉及使用12脉波换流单元(由三相桥(双路)连接组成)的两端HVDC系统与故障和开关相关的瞬态性能,但不包括多端HVDC输电系统。然而,讨论了作为两端系统一部分的并联换流器和并联线路的某些方面。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。本报告未考虑二极管阀。 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在IEC 60146-1-1、IEC 60146-1-2和IEC 60146-1-3中给出。未考虑电压源换流器。 本报告由三部分组成。IEC 60919-2涵盖瞬态性能,将伴随配套文件IEC 60919-1(稳态性能)和IEC 60919-3(动态性能)。已努力避免三部分之间的重复。因此,本报告的用户在准备购买两端HVDC系统的规范时,应考虑所有三个部分。 提醒读者注意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。虽然此处未定义设备规范与测试要求,但指出了可能影响系统性能规范的内容。注意,详细的地震性能要求不在本技术报告中。此外,由于不同HVDC系统之间存在许多可能的差异,这些差异未详细考虑。因此,本报告不应直接用作特定项目的规范,而是为根据实际电力传输方案的系统需求定制适当规范提供基础。本报告无意区分用户和制造商对指定工作的责任。 本报告中使用的高压直流(HVDC)传输术语和定义见IEC 60633。 由于设备项目通常是单独指定和采购的,HVDC传输线、接地电极线和接地电极仅因其对HVDC系统性能的影响而被包括在内。 就本报告而言,假设HVDC变电站由一个或多个安装在同一位置的换流单元组成,连同建筑物、电抗器、滤波器、无功电源、控制、监控、保护、测量和辅助设备。虽然本报告未讨论交流开关站,但包括交流滤波器和无功电源,尽管它们可能连接到与HVDC变电站分开的交流母线。 [外文原描述]: IEC TR 60919-2:2008+A1:2015+A2:2020 provides guidance on the transient performance and fault protection requirements of high voltage direct current (HVDC) systems. It concerns the transient performance related to faults and switching for two-terminal HVDC systems utilizing 12-pulse converter units comprised of three-phase bridge (double way) connections but it does not cover multi-terminal HVDC transmission systems. However, certain aspects of parallel converters and parallel lines, if part of a two-terminal system, are discussed. The converters are assumed to use thyristor valves as the bridge arms, with gapless metal oxide arresters for insulation co-ordination and to have power flow capability in both directions. Diode valves are not considered in this report. This second edition cancels and replaces the first edition, published in 1991, and constitutes a technical revision. It includes the following main changes with respect to the previous edition: - it concerns only line-commutated converters; - isignificant changes have been made to the control system technology; - some environmental constraints, for example audible noise limits, have been added; - the capacitor coupled converters (CCC) and controlled series capacitor converters (CSCC) have been included. This consolidated version consists of the second edition (2008), its amendment 1 (2015) and its amendment 2 (2020). Therefore, no need to order amendment in addition to this publication.
