Arc Fault and Flash Signal Analysis of DC Distribution System Using MATLAB Simulink

An arc fault is a discharge of electrical energy through the air. Under normal operation two conductors are connected and the flow of electrons passes through the essentially zero resistance path. If the connection is corroded or impure, it will have resistance and heat is generated. Over time the heat will wear down the contact and result in small arcs between connections. These arcs begin as low current faults, but given enough time they have the potential to breakdown to another phase or ground conductor resulting in a dangerous high current fault. In this paper, a new approach using WT base spectral energy calibration for arc fault analysis and classification with Fuzzy Logic Controller in dc systems is projected. In this approach we were design a cassie arc model for representation of practical arc condition. The arc voltage was analyzed using wavelet analysis and that feature of wavelet then utilized for design fuzzy rule base data. The method of detection associate arc fault involves solar PV output voltage analysis and so feature identification. This complete system was implemented and tested in MATLAB simulink 2015 atmosphere.
