Series Arc Fault Modelling in Photovoltaic Resistive Systems

Series arc fault modelling provides an effective simulation approach for understanding arc fault characteristics in photovoltaic (PV) systems. However, the measured arc fault signals are synthetic results between arc faults and many system interference factors, which makes the modelling process complicated. This paper aims at providing an effective arc fault model for the simulation research in PV resistive systems. In this paper, various arc fault data are acquired through the designed experiment platform firstly. Then the establishment direction is summarized for the arc fault modelling in PV resistive systems. Next, the series arc fault model is proposed by combining the U-I model and pink noise model. Finally, the simulation analysis of series arc fault is carried out in PV resistive systems. By comparing with the obtained experimental data, the effectiveness of the arc fault model is verified.
