高压变电站用电气设备.产品和系统标准的通用建议.第1部分:交流

[中文适用范围]： IEC 指南 111 的此部分为横向出版物，为高压变电站（高于 1 kV）的产品和系统标准的协调提供指导。它涉及大多数情况下在高压 (HV) 变电站中发现的交流设备。本文件包含所有高压变电站产品和系统标准的通用规范建议，每个建议都由每个技术委员会的特定技术背景补充，这自然保留了其技术选择的自由。本文件适用于制定变电站交流部分的高压电力电子设备的产品和系统标准。注 1：与直流 (DC) 相关的 IEC 指南 111-2 正在制定中。一旦发布，IEC 指南 111-2 将适用于制定变电站 HVDC 部分的产品和系统标准。注2：IEC 标准化管理委员会 (SMB) 已决定，类似本指南的指南可以包含强制性要求，所有 IEC 委员会在开展本指南范围内的技术工作时均应遵守这些要求，也可以包含可遵循或可不遵循的指导性要求。本指南中的强制性要求以“应”字标识。仅供指导的陈述以动词“应当”标识。（参见 ISO/IEC 指令，IEC 补充规定第 1 部分，A.1.1。） [外文原描述]： IEC Guide 111-1:2023 is a horizontal publication which gives guidance for the harmonization of product and system standards for HV substations (higher than 1 kV). It addresses AC equipment which is found in high-voltage (HV) substations in most cases. This document contains recommendations for common specifications for all HV substation product and system standards, each of which is augmented by the technical background specific to each technical committee, which naturally retains freedom in its technical choices. This document is applicable when developing product and systems standards for HV power electronic equipment for the AC part of the substation. This first edition of IEC Guide 111-1, together with IEC Guide 111-2, cancels and replaces the second edition of IEC Guide 111 published in 2004. The main changes with respect to the previous edition are as follows: IEC Guide 111 is revised into two parts – Part 1 for AC and Part 2 for DC (Part 2 to be prepared); the scope of the document has been expanded to cover electric equipment in AC high-voltage substations; new definitions have been included; normal conditions have been revised; a general revision of other clauses.
