MODELS, DETECTION METHODS, AND CHALLENGES IN DC ARC FAULT: A REVIEW
Keywords:DC Arc fault detection, Fault diagnosis, Photovoltaic systems (PV), Fire hazard photovoltaic, Fault detection method
AbstractThe power generation of solar photovoltaic (PV) technology is being implemented in every nation worldwide due to its environmentally clean characteristics. Therefore, PV technology is signiﬁcantly growing in the present applications and usage of PV power systems. Despite the strength of the PV arrays in power systems, the arrays remain susceptible to certain faults. An effective supply requires economic returns, the security of the equipment and humans, precise fault identiﬁcation, diagnosis, and interruption tools. Meanwhile, the faults in unidentiﬁed arc lead to serious ﬁre hazards to commercial, residential, and utility-scale PV systems. To ensure secure and dependable distribution of electricity, the detection of such hazards is crucial in the early phases of the distribution. In this paper, a detailed review of modern approaches for the identiﬁcation of DC arc faults in PV is presented. In addition, a thorough comparison is performed between various DC arc-fault models, characteristics, and approaches used for the identiﬁcation of the faults.
