The use of voltage source converter (VSC) based HVDC transmission for the interconnection of various power networks is increasing day by day. However, VSCs susceptibility to DC faults, particularly the potential damage caused to the converter switches due to overcurrent, is an issue. The fault clearing must be done very rapidly, to limit the effect of the fault on neighboring networks. This paper analyses the two terminal behavior of a VSC- based HVDC system under DC fault condition. In this work, HVDC link is connected between the systems of two different frequencies. Simulations are carried out in RSCAD/RTDS>sup/sup< software and the performance of the system is analyzed for DC faults and the results are presented.
