NPR-IEC/TR 62001-1, which is a Technical Report, provides guidance on the specifications of AC filters for high-voltage direct current (HVDC) systems with linecommutated converters and filter performance calculation. This document deals with the specification and design evaluation of AC side harmonic performance and AC side filters for HVDC schemes. It is intended to be primarily for the use of the utilities and consultants who are responsible for issuing the specifications for new HVDC projects and evaluating designs proposed by prospective suppliers. 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 Power Line Carrier (PLC) and radio interference spectra. The bulk of this document concentrates on the "conventional" AC filter technology and linecommutated HVDC converters. The changes entailed by new technologies are also discussed.
