“…(a) Series arc fault: this fault is caused by a discontinuity in the current path due to a broken conductor, loosened conductor, or a high impedance connection due to corrosion (b) Parallel arc faults: parallel faults also occur due to mechanical damage, nesting rodents, or failure within the PV module Contrary to AC systems, the current through DC arc does not possess a zero crossing [24,25]; thus, there is a likelihood that a PV array arc will be sustained. Parallel AF draws large amount of fault current as compared to series AF due to large voltage potential difference involved in the former [26].…”

The environmentally clean nature of solar photovoltaic (PV) technology causes PV power generation to be embraced by all countries across the globe. Consequently, installation and utilization of PV power systems have seen much growth in recent years. Although PV arrays of such systems are robust, they are not immune to faults. To guarantee reliable power supply, economic returns, and safety of both humans and equipment, highly accurate fault detection, diagnosis, and interruption devices are required. In this paper, an overview of four major PV array faults and their causes are presented. Specifically, ground fault, line-line fault, arc fault, and hot spot fault have been covered. Next, conventional and advanced fault detection and diagnosis (FDD) techniques for managing these faults are reviewed. Moreover, a single evaluation metric has been proposed and utilized to evaluate the performances of the advanced FDD techniques. Finally, based on the papers reviewed, PV array fault management future trends and possible recommendations have been outlined.

Abstract. Electrical arc faults that occur in photovoltaic systems represent a danger due to their economic impact on production and distribution. In this paper we propose a complete system, with focus on the methodology, that enables the detection and localization of the arc fault, by the use of an electromagnetic-acoustic sensing system. By exploiting the multiple emissions of the arc fault, in conjunction with a real-time detection signal processing method, we ensure accurate detection and localization. In its final form, this present work will present in greater detail the complete system, the methods employed, results and performance, alongside further works that will be carried on. IntroductionThis current work intends to propose a case-study of an electrical arc fault detection and localization system, with emphasis on the detection and localization principles, and also on statistical performance evaluation. The physical principle behind this system is the simultaneous generation of the arc fault of electromagnetic waves, as well as sound (and low ultrasound) pressure waves. By exploiting this bidimensionality of the arc phenomena, the system (and the signal processing methods that it uses) manages to correctly assess the presence of the arc fault, as well as the distance at which it occurred.In the first section, a brief description of previous and current embodiments of the system will be presented. Following, in section 2, we will describe the necessary signal processing in order to ensure robust detection of the arc fault. And in section 3, results and performances for one type of measurement will be presented, followed by our conclusions. The full paper version of the article will focus on the statistical evaluation of methods, in a wider range of configurations.

“…Due to the complexity of the MHD model, some researchers chose simpler arc models to study how the arc and the circuit affect each other. In [28], the arc was simplified as a constant value resistor in the simulation, and the influences of the series and parallel arc on the PV system were analyzed. In [29], series DC arc faults were simulated in a DC microgrid.…”

Despite the rapid development of photovoltaic (PV) industry, direct current (DC) fault arc remains a major threat to the safety of PV system and personnel. While extensive research on DC fault arc has been conducted, little attention has been paid to the long-time interactions between the PV system and DC arc. In this paper, a simulation system with an arc model and PV system model is built to overcome the inconvenience of the fault-arc experiments and understand the mechanism of these interactions. For this purpose, the characteristics of the series DC arc in a small grid-connected PV system are first investigated under uniform irradiance. Then, by comparing with different arc models, the Habedank model is selected to simulate the fault arc and a method to determine its parameters under DC arc condition is proposed. The trends of simulated arc waveforms are consistent with the measured data, whose fitting degree in adjusted R-squared is between 0.946 and 0.956. Finally, a phenomenon observed during the experiment, that the negative perturbation of the maximum power point tracking (MPPT) algorithm can reduce the arc current, is explained by the proposed model.
