BS PD IEC/TR 62001-4:2016, which is a Technical Report, provides guidance on the basic dataof AC side filters for high-voltage direct current (HVDC) systems and their components suchas ratings, power losses, design issues and special applications, protection, seismicrequirements, equipment design and test parameters.
This document covers AC side filtering for the frequency range of interest in terms ofharmonic distortion and audible frequency disturbances. It excludes filters designed to beeffective in the power line carrier (PLC) and radio interference spectra.
It concerns the "conventional" AC filter technology and line-commutated HVDC converters.
