Power swing blocking function is integrated in distance relays to ensure security during power swing. However, if a fault occurs during power swing, it must be detected and cleared by the relay as quickly as possible. Since power swings and three-phase faults are both balanced phenomena, discriminating them is very challenging. This paper proposes a method to detect three-phase fault during power swing by computing the Hilbert envelope of the current waveform followed by zero-frequency filtering. The average rate of change in amplitude of the zero-frequency filtered current is used as the fault detector index. The discrimination capability between three-phase fault and power swing of the extracted feature is the main contribution of this paper. Results of various possible test cases simulated through EMTDC/PSCAD show that the proposed method is fast and reliable in detecting three-phase faults during power swings.
