高压直流(HVDC)系统. 交流滤波器的规格和设计评估指南. 第3部分: 建模

[中文适用范围]： IEC TR 62001 的这一部分是一份技术报告，提供有关转换器之间的谐波相互作用、预先存在的谐波、交流网络阻抗建模和交流滤波器性能仿真的指导。本文档的范围涵盖了谐波失真和可听频率干扰方面感兴趣频率范围的交流侧滤波。它不包括设计用于在 PLC 和无线电干扰频谱中有效的滤波器。本文档涉及“传统”交流滤波器技术和线路换向高压直流 (HVDC) 转换器。 [外文原描述]： IEC TR 62001-3:2016(E), which is a Technical Report, provides guidance on the harmonic interaction across converters, pre-existing harmonics, AC network impedance modelling and simulation of AC filter performance. The scope of this document covers AC side filtering for the frequency range of interest in terms of harmonic distortion and audible frequency disturbances. It excludes filters designed to be effective in the PLC and radio interference spectra. This document concerns the "conventional" AC filter technology and line-commutated high-voltage direct current (HVDC) converters. This first edition of IEC TR 62001-3, together with IEC TR 62001-1, IEC TR 62001-2 and IEC TR 62001-4, cancels and replaces IEC TR 62001 published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC TR 62001: a) expanded and supplemented Clause 6; b) new Clause 4; c) new Clause 5; d) new annexes on the location of worst case network impedance; e) accuracy of network component modelling at harmonic frequencies; f) further guidance for the measurement of harmonic voltage distortion; g) project experience of pre-existing harmonic issues; h) worked examples showing impact of pre-existing distortion; i) comparison of calculation methods.
