电能质量管理 第1部分：总则

[中文适用范围]： IEC TS 63222-1:2026 RLV 包含该国际标准的正式版本及其修订标记版。修订标记版仅提供英文，便于用户快速、便捷地对照正式标准与其上一版本之间的所有变更。 本标准旨在就公共电力供应网络中电能质量管理领域所适用的公认工程实践，提供与主要用例相关的条款。它总结电能质量管理的相关运作情况，梳理现行标准，明确电能质量评估工作的要求，并推动电能质量管理最佳实践的制定。电能质量管理范畴涵盖与网络管理共用的用例及相应的电能质量要求，包括支持客户侧网络运行、网络及扩展规划等内容。 本文件以“用例”形式呈现电能质量管理实践中可能存在的“共性且重复使用”的场景。所列用例实施方案仅供信息参考。文件进一步将共通要求提炼为具体条款，作为后续标准化工作的基础，围绕与给定系统交互的角色展开；接口要求则留待后续标准化活动处理。文中还讨论了电能质量管理中各相关方（如网络运营商、网络用户等）之间的关系。 本第二版取消并替代2022年发布的第一版。与前一版相比，本版包含以下重要技术变更： - 完善了 IEC 63222-1:2022 中规划的用例，新增四个业务用例和三个系统用例； - 对 IEC 63222-1:2022 中部分措辞及技术细节进行了修订。 [外文原描述]： IEC TS 63222-1:2026 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 63222-1:2026 is intended to provide provisions associated to the main use cases regarding recognized engineering practices applicable to power quality management in public electric power supply networks. It summarizes the operation in power quality management and investigates the current standards, for requirement of power quality assessment work, as well as to promote the development of power quality management best practices. The power quality management domain groups use cases and associated power quality requirement common to network management, including customer support network operation, network and extension planning. This document captures possible "common and repeated usage" of power quality management under the format of "use case". Use case implementations are given for information purpose only. This document derives the common requirement as provisions by further standardization activities, in terms of actors interacting with the given system. The interface requirement is considered for later standardization activities. The relationship of the stakeholders in power quality management, such as network operator, network user, etc, are discussed in the document. This second edition cancels and replaces the first edition published in 2022. This edition includes the following significant technical changes with respect to the previous edition: - this document completes the use cases planned in IEC 63222-1:2022: four business use cases and three system use cases are added; - this document makes adjustments to the wording of certain phrases and technical details in IEC 63222-1:2022.
