This paper is discussed a transient current-based microgrid connected power system protection scheme using the Wavelet Approach described on wavelet detailed coefficients of Mother Biorthogonal 1.5 wavelet. The proposed algorithm is tested in a microgrid connected power systems environment and proved for the detection, discrimination, and location of faults which is almost independent of fault impedance, fault inception angle (FIA), and fault distance of feeder line.
