Empirical Wavelet Transform-Based Differential Protection Scheme for Micro-Grid
https://orcid.org/http://orcid.org/0000-0001-7396-8926
This paper proposes an empirical wavelet transform (EWT)-based differential protection scheme for micro-grids. EWT offers better time–frequency representation of the signal as compared to wavelet transform and empirical mode decomposition which have the limitations like noise and mode mixing effect. The currents attained at both the ends of the line will be handled through EWT for extracting the intrinsic mode functions which are further used to compute the differential energy. The differential energy is used to identify the fault in the micro-grid operating in different configurations. The proposed work is verified for various faults, high impedance faults which are tested on a standard micro-grid model. The results show the suitability of the proposed scheme for micro-grid protection.
