1 Scope This part of IEC 62001 provides in-depth consideration regarding three particularly important aspects of design, which are also mentioned elsewhere in other parts of the IEC 62001 series, which are: AC network impedance modelling, the treatment of pre-existing harmonics in performance and rating calculations, and harmonic interaction across converters (cross-modulation). This document concentrates on passive AC filter technology and line-commutated high-voltage direct current (HVDC) converters, but much of the content is equally relevant to VSC converter technology. Where there is a distinction, this is indicated in the text. 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 specifically designed to be effective in the PLC and radio interference spectra.
