More and more high voltage direct current (HVDC) converters are being located in a load area in
the Yangtze River Delta Region in China. It’s large transmission capacity and intensive placement are hardly
seen in other countries. Accurate and reliable study tools and methods are extremely needed for power system
engineers and researchers to deal with such problems which were never met before and otherwhere. A novel
approach on electromagnetic modeling of alternating current / direct current (AC/DC) system is proposed and
simulation is carried out to replay a real AC 3-phase to ground fault on a multi-infeed high voltage direct current
(MIHVDC) system. AC system is specially simplified. Dynamic models and real parameters are adopted in
main AC/DC equipments concerned and retained. Modeling and simulation are based on the power system
computer aided design/electro-magnetic transient in direct current (PSCAD/EMTDC) system software package.
Comparisons between simulation results and the records from the fault recorders are studied including both AC
and DC quantities.
