An alternative approach to provisions of the Network Code on blocking HVDC LCC systems during short-circuits in AC network [PDF]
E3S Web of Conferences, 2019 The Network Code for HVDC systems introduces a requirement for such systems to remain in operation in an AC network during short-circuits. This requirement (among others) is determined by a time curve of a minimum voltage in HVDC connection point.
