Mixed Operation

Dc distribution systems are multiterminal systems characterized by complexity and mixed operation of ac and dc. Ac side faults are more likely to happen and may cause more serious consequences compared with dc transmission systems, thus must be considered seriously. In this paper, ac side faults of the prototype dc distribution system under high impedance grounding scheme are analyzed in detail. Fault characteristics of dc side voltages and currents under ac side faults are drawn and sorted. A protection scheme of ac side faults is proposed based on dc voltage and current measurements. The effectiveness of the protection scheme proposed is demonstrated by simulation under PSCAD/EMTDC.
