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.
