Fault Section Estimation in Radial LVDC Distribution System Using Wavelet Transform

The demand for low voltage DC (LVDC) distribution systems is increasing due to the rapid development of power conversion technology, increase DC-based digital loads, and expansion distributed generation (DG). For stable operation LVDC system, it necessary develop a protection method. In this paper, fault section estimated using wavelet transform (WT) in system. classified into line bus. characteristics current at each part are analyzed simple actual Based on analysis, algorithm estimation proposed detail component after performing WT. results estimations verified through various simulations EMTP MATLAB. can be utilized schemes
