A fault-transient synchrophasor is computed over a window of pre-fault and fault samples. A faultsynchrophasor is computed over a window of fault samples only. fault-transient synchrophasors are discarded and are generally not used in the synchrophasor applications. Recently, an algorithm has been proposed to compute faultsynchrophasor from fault-transient synchrophasor in phasor data concentrator (PDC). The accuracy of the existing algorithm deteriorates due to fault-induced transients and inaccurate fault starting time. A robust algorithm has been proposed to compute faultsynchrophasor from fault-transient synchrophasor in PDC. The proposed algorithm does not use fault starting time in the calculations. It also performs better than the existing algorithm when fault-induced transients are present in the signal. The proposed algorithm is simple, non-iterative and performs satisfactorily in various investigated scenarios. The advantage of the proposed algorithm has been demonstrated in the context of fault location application.
