This is a distance relay protection scheme in PSCAD. Four transmission line PSCAD functions are used to model two 100km transmission lines and simulate faults along the lines. Tline1+Tline2=100km and ...

ABSTRACT: The fault recovery of VSC-HVDC transmission system is often influenced by many factors, such as the reactive power compensation characteristics of the inverter and the dynamic performance of ...

Abstract: Taking Jinnan ± 800kV ultra-high voltage direct current power transmission system as study object, this paper discusses simulation model of UHVDC by PSCAD /EMTDC (Power system computer aided ...
