Implications for harmonics and filtering of the installation of HVDC converter stations in close proximity

This Technical Brochure examines the full extent of possible technical concerns in the area of harmonics and filtering of the installation of HVDC converter stations in close proximity. It provides guidance on the pre-specification studies to screen the possibility of harmonic interactions and to determine specific system data and technical requirements, such as network harmonic impedance, reactive power controller philosophy and harmonic limits. It will also provide a basis of knowledge of the aspects to be considered in performance and rating studies and the possible implications for the design of the filtering equipment. The possible approaches for co-ordination of filter designs is discussed in the Brochure, taking into account not only technical aspects, but also economic, contractual…
