چکیده
Abstract A large number of connecting wires and electrical contact points exist in photovoltaic power generation systems, which can easily cause the occurrence an arc fault. Failure to detect isolate faults time will result serious fire hazards. In document, a new approach fault monitoring positioning built on variational mode decomposition is presented for variety series DC systems. The frequency-domain properties signals collected under different working conditions are obtained by use (VMD), detection matching changes features same sub-mode. Finally, 400KW system model Matlab/Simulink simulation verification. outcome indicated that technique capable accurately detecting locating faults.

Series Arc Fault Detection Algorithm Based on Autoregressive Bispectrum Analysis
Arc fault is one of the most critical reasons for electrical fires. Due to the diversity, randomness and concealment of arc faults in low-voltage circuits, it is difficult for general methods to protect all loads from series arc faults. From the analysis of many series arc faults, a large number of high frequency signals generated in circuits are found. These signals are easily affected by Gaus...

متن کاملResearch on Low-voltage Series Arc Fault Detection Method Based on Least Squares Support Vector Machine
Arc fault is one of the important reasons of electrical fires. In virtue of cross talk, randomness and weakness of series arc faults in low-voltage circuits, very few of techniques have been well used to protect loads from series arc faults. Thus, a novel detection method based on support vector machine is developed in this paper. If series arc fault occurs, high frequency signal energy in circ...
