A Novel Fault Location Technique for VSCHVDC Cable of Offshore Wind Farm

large and remote offshore wind farms (OWFs) use voltage source convertor (VSC) systems in order to send electrical power to main grid. SubmarineHVDC cables are used as transmission link. They are liable to insulation breakdown. Fault location in HVDC cable is one of major issue in these systems. Exactlocating of fault can significantly reduce high cost of repairing of submarine HVDC cable. In this paper, a novel method is presented in order to find fault place.Determination of fault place is done by using transient current of cable sheath when fault occurs. Thesimulation results show that suggested technique is capable of locating different faults in an accurate way
