Abstract
This paper evaluates the performance of phasor-based and traveling-wave fault-location techniques for submarine export cables in offshore wind farms that utilize grid-following Type-4 inverter-based resources (IBRs). A detailed electromagnetic transient (EMT) model of the Horns Rev 2 offshore wind farm is used to evaluate four phasor-based techniques (impedance-based, simple reactance, Takagi, and modified Takagi) and two traveling-wave techniques (single-ended and double-ended). Among the phasor-based methods, the simple reactance and modified Takagi approaches provide the most consistent estimates, although both require approximately 50-60 ms for transient stabilization. In contrast, the single-ended and double-ended traveling-wave methods achieve the highest location accuracy, supported by transformer stray capacitances that preserve high-frequency wavefronts at the IBR side. The results offer guidance for selecting reliable fault-location techniques for offshore wind export cable protection and monitoring.
