Abstract:

Photovoltaic systems are one of the most promising solutions of clean energy. The scale of PV plants ranges from the domestic to commercial applications. Like every other power system, they are prone to various kind of faults. In this talk, I will give an overview of the major faults in a PV plants. In addition, emphasis will be given to electrical faults i.e. line to line (L-L) and line to ground (L-G) faults. PV array fault occurs gradually due to the slow deterioration of PV cable or panel insulation. As a result, the insulation impedance, slowly disappears from the high value to 0. Most of the literature methods analyze and detect faults at zero fault impedance. However, for a finite fault resistance, the detection, classification and localization of the fault becomes a challenging problem. The state-of-the-art algorithms in this regard will be discussed in detail.
