This article presents a novel method to locate the voltage sag source based on directional overcurrent (DOC) relay information. In this method the source of voltage sag is located by using the variation of magnitude of measured current positive-sequence component during sag and presag conditions and the sign of its phase-angle jump. The performance of the proposed method is compared with distance relay (DR) and phase change in sequence current (PCSC) methods by using PSCAD/EMTDC on a simulated case study. The results show the good and unique performance of the novel method in cases where only currents are recorded.

W artykule zaprezentowano nową metodę lokalizacji źródła zapadu napięcia bazującej na informacji o kierunkowym przeciążeniu prądowym. Źródło zapadu napięcia jest lokalizowane na podstawie pomiaru amplitudy i fazy prądu w czasie zapadu i przed zapadem. Porównano metodę z z dotychczas stosowanymi metodami DR i PCSC.
