This paper proposes a novel dc series arc fault detection and localization method in PV systems using parallel capacitors, which can detect the variation of the current with high sensitivity as only the high frequency components of the arc current can pass through the capacitors.
A capacitor is used in parallel with the solar panel array. When the arc is generated, the dc component of the current does not pass through the capacitor, but the high frequency components do. Therefore, both the variations of the rate of change and the spectrum of the capacitor current can be detected with good sensitivity.
A detection method for series dc arc faults in a PV system based on time and frequency characteristics of a parallel capacitor current is proposed. Series and parallel solar panel array systems are constructed, and a capacitor is paralleled with the load.
Against the backdrop of accelerating the achievement of the “dual carbon” goals, the installation and use of photovoltaic power generation systems have been increasing year by year . With the rapid promotion of photovoltaic systems, the issue of arc faults in DC systems has become prominent .
Arc fault in a PV string can be localized comparing capacitor current amplitudes. A dc series arc fault is difficult to detect and localize due to the lack of a current zero crossing point. Unless there is an adequate protection, these faults can pose a threat to the stable operation of a photovoltaic (PV) system.
Though it is hard to localize the series arc fault within one panel string accurately, it is still possible to identify the possible locations near to or far from the parallel capacitor. 4.3. Detecting method for series arc fault
