标准摘要
[中文适用范围]： 本部分IEC 63222旨在提供有关电力质量预测评估中用户特性的公认工程实践的规定。总结了在规划阶段对非线性、不平衡、冲击和波动负载或发电建模的最佳实践，以预测公共电力系统中的电力质量扰动。 本文件侧重于电力网络中交流电力质量分析的频域建模，通常在高达50次谐波范围内（50 Hz系统中为2.5 kHz或60 Hz系统中为3 kHz）。不平衡在三相系统中分析，仅考虑负序分量。提供的方法和建模指南适用于作为扰动源的用户设施与电力系统的连接表示。网络元素的建模不在本文件范围内。 这些指南在定义用户设备的电力质量性能规范时将非常有用。它们还将帮助用户在建模其设施时评估或证明符合系统所有者/运营商提供的排放限制，并调查和指定缓解措施。 [外文原描述]： IEC TS 63222-3:2024 is intended to provide provisions regarding recognized engineering practices applicable to assess the user’s characteristics in power quality predicted assessment. It summarizes the best practice in non-linear, unbalanced, impact and fluctuating loads or generations modelling for power quality disturbance anticipation in public power systems at the planning stage. This document focuses on frequency-domain modelling for AC power quality analysis in electric power networks, typically in the range up to the 50th harmonic (2,5 kHz in 50 Hz systems or 3 kHz in 60 Hz systems). Unbalance is analyzed in three-phase systems and only negative sequence component is considered. The approach and modelling guidelines provided are valid on the representation of user installations connected to power systems acting as sources of disturbance. Modelling of the network elements is out of the scope of the document. These guidelines will be valuable in the definition of power quality performance specifications for user equipment. They will also assist users when modelling their installation to assess or demonstrate compliance with the emission limits provided by the system owner/operator and to investigate and specify mitigation measures.
