With the study on the transient state of series compensated lines under symmetrical and asymmetrical fault conditions, it’s obtained that low frequency component is much larger than aperiodic component of the measured transient current if the fault location is behind the series compensated capacitor. Due to the non-linear volt-ampere characteristics of MOV, the equivalent capacitive of series compensated device changes with time. Hence, the frequency of low frequency component caused by series compensated capacitor is time-varying. Hilbert-Huang Transformation is applied to analyze the instantaneous frequency and amplitude of the low frequency component to identify the fault location. The simulation results prove this method works.

W artykule przedstawiono metodę lokalizacji awarii symetrycznych i niesymetrycznych w układach kompensacji szeregowej. Określono wpływ charakterystyki napięciowo-prądowej łącznika warystorowego na wartość harmonicznych niższego stopnia, wprowadzanych do sieci. Zastosowano transformację Hilbert-Huang w celu analizy chwilowej częstotliwości i amplitudy składowej niskiej częstotliwości oraz określenia miejsca awarii. Wykonano badania symulacyjne.
