These Guidelines and Parameter Lists to Functional Specifications describe specific functionalrequirements for HVDC Grid Systems. The terminology “HVDC Grid Systems” is used here describingHVDC systems for power transmission having more than two converter stations connected to a commonDC circuit.
While this document focuses on requirements, that are specific for HVDC Grid Systems, some requirementsare considered applicable to all HVDC systems in general, i.e. including point-to-point HVDC systems.Existing IEC, Cigre or other documents relevant have been used for reference as far as possible.
