Dc Microgrid Fault Detection Using Multiresolution Analysis Of Traveling Waves, Rudy Montoya
Dc Microgrid Fault Detection Using Multiresolution Analysis Of Traveling Waves, Rudy Montoya
Mechanical Engineering ETDs
Fast detection and isolation of faults in a DC microgrid is of particular importance. Fast tripping protection (i) increases the lifetime of power electronics (PE) switches by avoiding high fault current magnitudes and (ii) enhances the controllability of PE converters. This thesis proposes a traveling wave (TW) based scheme for fast tripping protection of DC microgrids. The proposed scheme utilizes a discrete wavelet transform (DWT) to calculate the high-frequency components of DC fault currents. Multiresolution analysis (MRA) using DWT is utilized to detect TW components for different frequency ranges. The Parseval energy calculated from the MRA coefficients are then used …
