“…Performance impact of arc faults at different dc microgrid locations and their implications on controller protection algorithms is explored in [10]. For example, for a constant power load, an input side series arc fault can actually increase the arc current in response to a drop in input voltage [4]. The problem with unintentional unplugging of home appliances in a residential dc distribution system is highlighted in [11].…”

Low voltage dc distribution grids face issues associated with arc faults, aggravated by the absence of current zero crossing. The focus of this work is to comprehensively develop a method of series arc fault detection at the load side power electronics, based on the electrode dependent initial voltage drop occurring at the arc initiation. The proposed arc detection algorithm is described along with the structure and time constants of the designed bandpass filter. The operational boundaries of the arc detection algorithm are defined for copper electrodes depending on the set threshold voltage and the system parameters, like grid inductance, resistance and the load capacitance. Further, the detection time and the zone of guaranteed positive detection are depicted. These are validated through test simulations on the state space model of the system. Finally, experimental validation of the proposed scheme is carried out, wherein, a series arc is generated in the dc circuit and the programmed micro-controller provides a real time signal upon detecting the arcing event. The results on variation in detection time with set threshold voltage is also presented experimentally.

“…Sensitive detection, differentiation and selective clearance of parallel and series dc arc faults is one of the important protection aspects. As compared to ac microgrids, dc distribution systems are more susceptible to sustained arcs due to the absence of current zero crossing [4], [5].…”

“…Moreover, series arcing can be an issue when high power loads are unplugged. Special plugs with leading pins is one of the possible solutions, but also selective load side arc detection could be implemented [32]. Furthermore, coordination with frequency-based backup protection would need to be standardized.…”

“…Plug-related arching for consumer electronics needs to be investigated as there is not an inherent zero voltage crossing in the dc bus to minimize it. With constant power loads dominating any microgrid, arching current increases when plugging out a load from the dc bus [28]. The influence of constant power loads in arching during plugging in and out has not been addressed.…”
