Abstract  Series DC arcing fault pose an extreme safety risk in DC power system because it is difficult to be detected. A sliding discrete fourier transform (DFT) based arcing fault recognition method is proposed to meet the requirement of real-time in detection and reduction in algorithm complexity. The arcing initiation stage is the best moment for fault detection based on analysis both in time domain and in frequency domain. Accordingly, three characteristic frequencies, 40 kHz, 80 kHz and 100 kHz, are selected for the point by point sliding DFT calculation. Moreover, a time-window of 200μs is used to implement the algorithm for simplicity and accuracy. Finally, it is concluded that all the three spectrums increase significantly during the arcing fault. And the sliding DFT algorithm can be applied for series DC arcing fault recognition.
