Abstract
In this paper, a new time-domain-based method is proposed for fault location in HVDC transmission lines. In the proposed method, an equation is derived for locating the fault for different transmission-line models (lumped-line model, \(\uppi \)-line model, and distributed-line model). Then, a method is suggested to precisely determine the transmission-line resistance using DC component of voltage and current at the both terminals (pre-fault). The performance of the proposed method is evaluated based on a test system by the PSCAD/EMTDC and MATLAB software. The performance and precision of the proposed methods are evaluated for short-circuit fault in different conditions, such as different fault resistances, difference fault distances, different minimum injected current of the inverter during the fault, and different pre-fault conditions. The simulation results confirm that the proposed method is much more accurate in locating faults compared to other counterparts.
